Protein diffusion in Escherichia coli

This dissertation describes the creation of a system to provide insight about the affects of protein expression on intracellular diffusion. Fluorescence recovery after photobleaching (FRAP) is used to obtain diffusion coefficients. Nuclear magnetic resonance spectroscopy detection of 19F isotopic-enriched proteins and fluorescent labeling with FlAsH and were attemped before settling on FRAP studies with green fluorecent protein (GFP). To regulate protein levels in Escherichia coli, several vector and promoter combinations were tested. Eventually, a single vector was created containing the structural gene for GFP under the lac promoter and a test protein under the araBAD promoter. With this vector, the test protein was expressed at varying levels and GFP was expressed at a constant level. Although chymotrypsin inhibitor 2 was originally chosen as the test protein, it was quickly replaced by alpha-synuclein, maltose binding protein, tau-40, and calmodulin. My most important result is that regardless of the type or amount of protein that was co-expressed, the GFP diffusion coefficient remained constant. We conclude that expression of these soluble proteins has little to no effect on the diffusion of GFP. Several disadvantages of FRAP became apparent in the process of obtaining these data. FRAP and the other common techniques for measuring translational diffusion, present numerous obstacles when working with structures that are only slightly larger than optical resolution, such as Escherichia coli cells. To overcome these obstacles, I also developed a new method to assess diffusion using through-prism total internal reflection fluorescence microscopy with continuous photobleaching. Here, the theoretical basis for this technique is presented. I demonstrate its applicability by measuring the diffusion coefficient, 6.3 ± 1.1 µm2/sec, of GFP in Escherichia coli cells

Sirtuin-mediated nuclear differentiation and programmed degradation in Tetrahymena

<p>Abstract</p> <p>Background</p> <p>The NAD⁺-dependent histone deacetylases, known as "sirtuins", participate in a variety of processes critical for single- and multi-cellular life. Recent studies have elucidated the importance of sirtuin activity in development, aging, and disease; yet, underlying mechanistic pathways are not well understood. Specific sirtuins influence chromatin structure and gene expression, but differences in their pathways as they relate to distinct chromatin functions are just beginning to emerge. To further define the range of global chromatin changes dependent on sirtuins, unique biological features of the ciliated protozoan <it>Tetrahymena thermophila </it>can be exploited. This system offers clear spatial and temporal separation of multiple whole genome restructuring events critical for the life cycle.</p> <p>Results</p> <p>Inhibition with nicotinamide revealed that sirtuin deacetylase activity in <it>Tetrahymena </it>cells promotes chromatin condensation during meiotic prophase, differentiation of heterochromatin from euchromatin during development, and chromatin condensation/degradation during programmed nuclear death. We identified a class I sirtuin, called Thd14, that resides in mitochondria and nucleoli during vegetative growth, and forms a large sub-nuclear aggregate in response to prolonged cell starvation that may be peripherally associated with nucleoli. During sexual conjugation and development Thd14 selectively concentrates in the parental nucleus prior to its apoptotic-like degradation.</p> <p>Conclusions</p> <p>Sirtuin activity is important for several functionally distinct events requiring global chromatin condensation. Our findings suggest a novel role for sirtuins in promoting programmed pycnosis by acting on chromatin destined for degradation. The sirtuin Thd14, which displays physiological-dependent differential localization within the nucleus, is a candidate for a chromatin condensation enzyme that is coupled to nuclear degradation.</p

Quantifying GFP Diffusion in Escherichia coli by Using Continuous Photobleaching with Evanescent Illumination

Fluorescence recovery after photobleaching and fluorescence correlation spectroscopy are the primary means for studying translational diffusion in biological systems. Both techniques, however, present numerous obstacles for measuring translational mobility in structures only slightly larger than optical resolution. We report a new method using through-prism total internal reflection fluorescence microscopy with continuous photobleaching (TIR-CP) to overcome these obstacles. Small structures, such as prokaryotic cells or isolated eukaryotic organelles, containing fluorescent molecules are adhered to a surface. This surface is continuously illuminated by an evanescent wave created by total internal reflection. The characteristic length describing the decay of the evanescent intensity with distance from the surface is smaller than the structures. The fluorescence decay rate resulting from continuous evanescent illumination is monitored as a function of the excitation intensity. The data at higher excitation intensities provide apparent translational diffusion coefficients for the fluorescent molecules within the structures because the decay results from two competing processes (the intrinsic photobleaching propensity and diffusion in the small structures). We present the theoretical basis for the technique and demonstrate its applicability by measuring the diffusion coefficient, 6.3 ± 1.1 µm2/sec, of green fluorescent protein (GFP) in Escherichia coli cells

Effects of Recombinant Protein Expression on Green Fluorescent Protein Diffusion in Escherichia coli

Fluorescence recovery after photobleaching was used to measure the diffusion coefficient of green fluorescent protein (GFP, 27 kDa) in Escherichia coli in the presence or absence of four coexpressed proteins: cytoplasmic maltose binding protein (42 kDa), tau-40 (45 kDa), α-synuclein (14 kDa), or calmodulin (17 kDa). The GFP diffusion coefficient remains constant regardless of the type of coexpresseed protein and whether or not the coexpressed protein was induced. We conclude that expression of these soluble proteins has little to no effect on the diffusion of GFP. These results have implications for the utility of in-cell nuclear magnetic resonance spectroscopy

19 F NMR Studies of α-Synuclein Conformation and Fibrillation

Fibrils of the intrinsically-disordered protein α-synuclein are hallmarks of Parkinson's disease. The fluorescent dye thioflavin T is often used to characterize fibrillation, but this assay may not provide quantitative information about structure and mechanism. To gain such information, we incorporated the 19F-labeled amino acid, 3-fluorotyrosine, into recombinant human α-synuclein at its endogenous tyrosine residues. Tyrosine 39 is in the positively-charged N-terminal region of this 140-residue protein. The other three, tyrosines, 125, 133, and 136, are near the C-terminus. 19F-nuclear magnetic resonance spectroscopy was used to study several properties of labeled α-synuclein, including its conformation; conformational changes induced by urea, spermine, and sodium dodecyl sulfate (SDS); its interaction with SDS micelles; and the kinetics of fibril formation. The results show that the tyrosines are in disordered regions but that there is some structure near position 39 that is disrupted by urea. SDS binding alters the conformation near position 39, but the C-terminal tyrosines are disordered under all conditions. The NMR data also indicate that SDS-micelle bound α-synuclein and the free protein exchange on the 10-ms time scale. Studies of fibrillation show the utility of 19F-labeled NMR. The data indicate that fibrillation is not accompanied by the formation of large quantities of low molecular-weight intermediates. Although dye-binding and 19F NMR data show that 1-mM SDS and 1-mM spermine accelerate aggregation compared to buffer alone, only the NMR data indicate that the species formed in SDS are smaller than those formed in buffer or buffer plus spermine. We conclude that 19F NMR spectroscopy is useful for obtaining residue-level, quantitative information about the structure, binding, and aggregation of α-synuclein

Protein Nuclear Magnetic Resonance under Physiological Conditions †

Almost everything we know about protein biophysics comes from studies on purified proteins in dilute solution. Most proteins, however, operate inside cells where the concentration of macromolecules can be >300 mg per mL. Although reductionism-based approaches have served protein science well for over a century, biochemists now have the tools to study proteins under these more physiologically-relevant conditions. We review a part of this burgeoning post-reductionist landscape by focusing on high-resolution protein NMR spectroscopy, the only method that provides atomic-level information over an entire protein under the crowded conditions found in cells

Attachment as an organizer of behavior: implications for substance abuse problems and willingness to seek treatment

BACKGROUND: Attachment theory allows specific predictions about the role of attachment representations in organizing behavior. Insecure attachment is hypothesized to predict maladaptive emotional regulation whereas secure attachment is hypothesized to predict adaptive emotional regulation. In this paper, we test specific hypotheses about the role of attachment representations in substance abuse/dependence and treatment participation. Based on theory, we expect divergence between levels of maladaptive functioning and adaptive methods of regulating negative emotions. METHODS: Participants for this study consist of a sample of adoptees participating in an ongoing longitudinal adoption study (n = 208). The Semi-Structured Assessment of the Genetics of Alcohol-II [41] was used to determine lifetime substance abuse/dependence and treatment participation. Attachment representations were derived by the Adult Attachment Interview [AAI; [16]]. We constructed a prior contrasts reflecting theoretical predictions for the association between attachment representations, substance abuse/dependence and treatment participation. RESULTS: Logistic regression was used to test our hypotheses. As predicted, individuals classified as dismissing, preoccupied or earned-secure reported the highest rates of substance abuse/dependence. Individuals classified as dismissing reported significantly lower rates of treatment participation despite their high rates of substance abuse/dependence. As expected, the continuous-secure group reported lowest rates of both substance abuse/dependence and treatment participation. CONCLUSION: The findings from this study identify attachment representations as an influential factor in understanding the divergence between problematic substance use and treatment utilization. The findings further imply that treatment may need to take attachment representations into account to promote successful recovery

Protein 19 F NMR in Escherichia coli

Although over expression and 15N enrichment facilitate the observation of resonances from disordered proteins in Escherichia coli, 15N enrichment alone is insufficient for detecting most globular proteins. Here we explain this dichotomy and overcome the problem while extending the capability of in-cell NMR by using 19F labeled proteins. Resonances from small (~10 kDa) globular proteins containing the amino acid analog 3-fluoro-tyrosine can be observed in cells, but for larger proteins the 19F resonances are broadened beyond detection. Incorporating the amino acid analog trifluoromethyl-L-phenylalanine allows larger proteins (up to 100 kDa) to be observed in cells. We also show that site specific structural and dynamic information about both globular and disordered proteins can be obtained inside cells by using 19F NMR

Protein Hydrolysates Are Avoided by Herbivores but Not by Omnivores in Two-Choice Preference Tests

Background: The negative sensory properties of casein hydrolysates (HC) often limit their usage in products intended for human consumption, despite HC being nutritious and having many functional benefits. Recent, but taxonomically limited, evidence suggests that other animals also avoid consuming HC when alternatives exist. Methodology/Principal Findings: We evaluated ingestive responses of five herbivorous species (guinea pig, mountain beaver, gopher, vole, and rabbit) and five omnivorous species (rat, coyote, house mouse, white-footed mouse, and deer mouse; N = 16–18/species) using solid foods containing 20% HC in a series of two-choice preference tests that used a nonprotein, cellulose-based alternative. Individuals were also tested with collagen hydrolysate (gelatin; GE) to determine whether it would induce similar ingestive responses to those induced by HC. Despite HC and GE having very different nutritional and sensory qualities, both hydrolysates produced similar preference score patterns. We found that the herbivores generally avoided the hydrolysates while the omnivores consumed them at similar levels to the cellulose diet or, more rarely, preferred them (HC by the white-footed mouse; GE by the rat). Follow-up preference tests pairing HC and the nutritionally equivalent intact casein (C) were performed on the three mouse species and the guinea pigs. For the mice, mean HC preference scores were lower in the HC v C compared to the HC v Cel tests, indicating that HC’s sensory qualities negatively affected its consumption. However, responses were species-specific. For the guinea pigs, repeated exposure to HC or C (4.7-h sessions; N = 10) were found to increase subsequent HC preference scores in an HC v C preference test, which was interpreted in the light of conservative foraging strategies thought to typify herbivores. Conclusions/Significance: This is the first empirical study of dietary niche-related taxonomic differences in ingestive responses to protein hydrolysates using multiple species under comparable conditions. Our results provide a basis for future work in sensory, physiological, and behavioral mechanisms of hydrolysate avoidance and on the potential use of hydrolysates for pest management
