    Influence of static and dynamic disorder on the visible and infrared absorption spectra of carbonmonoxy horseradish peroxidase

    Spectroscopy of horseradish peroxidase with and without the substrate analog, benzohydroxamic acid, was monitored in a glycerol/water solvent as a function of temperature. It was determined from the water infrared (IR) absorption that the solvent has a glass transition at 170-180 K. In the absence of substrate, both the heme optical Q(0,0) absorption band and the IR absorption band of CO bound to heme broaden markedly upon heating from 10-300 K. The Q(0,0) band broadens smoothly in the whole temperature interval, whereas the IR bandwidth is constant in the glassy matrix and increases from 7 to 16 cm(-1) upon heating above the glass transition. Binding of substrate strongly diminishes temperature broadening of both the bands. The results are consistent with the view that the substrate strongly reduces the amplitude of motions of amino acids forming the heme pocket. The main contribution to the Q(0,0) bandwidth arises from the heme vibrations that are not affected by the phase transition. The CO band thermal broadening stems from the anharmonic coupling with motions of the heme environment, which, in the glassy state, are frozen in. Unusually strong temperature broadening of the CO band is interpreted to be caused by thermal population of a very flexible excited conformational substrate. Analysis of literature data on the thermal broadening of the A, band of Mb(CO) (Ansari et al., 1987. Biophys. Chem. 26:337-355) shows that such a state presents itself also in myoglobin

    Am 22. September 2008 führten Hirota und Ishida die internationale Werkstatt "Japanische Kultur -durch 'KATA'(Form/Muster) erleben" in der Freien Universität Berlin durch. An diesem Tag gab es ungefähr 20 Teilnehmer: Professor Ch. Wulf und die 'Historische Anthropologie' Studenten/innen,die einige Übungen erfuhren. In unserer Werkstatt haben sie erst unter Leitung von Ishida die Schwertkunst,Stockkunst und Aikido erfahren. Dann hat Hirota ihnen einigen Bewegungsübung als japanische kulturelle Essenz angeboten. Dieser Artikel besteht aus einem Bericht dieser Werkstatt und dem Nachdenken von KATA,sonst (1) ist der Teil von Ishida

    Evaluation of multi-exponential curve fitting analysis of oxygen-quenched phosphorescence decay traces for recovering microvascular oxygen tension histograms

    Although it is generally accepted that oxygen-quenched phosphorescence decay traces can be analyzed using the exponential series method (ESM), its application until now has been limited to a few (patho)physiological studies, probably because the reliability of the recovered oxygen tension (pO2) histograms has never been extensively evaluated and lacks documentation. The aim of this study was, therefore, to evaluate the use of the ESM to adequately determine pO2 histograms from phosphorescence decay traces. For this purpose we simulated decay traces corresponding to uni- and bimodal pO2 distributions and recovered the pO2 histograms at different signal-to-noise ratios (SNRs). Ultimately, we recovered microvascular pO2 histograms measured in the rat kidney in a model of endotoxemic shock and fluid resuscitation and showed that the mean microvascular oxygen tension, 〈pO2〉, decreased after induction of endotoxemia and that after 2 h of fluid resuscitation, 〈pO2〉 remained low, but the hypoxic peak that had arisen during endotoxemia was reduced. This finding illustrates the importance of recovering pO2 histograms under (patho)physiological conditions. In conclusion, this study has characterized how noise affects the recovery of pO2 histograms using the ESM and documented the reliability of the ESM for recovering both low- and high-pO2 distributions for SNRs typically found in experiments. This study might therefore serve as a frame of reference for investigations focused on oxygen (re)distribution during health and disease and encourage researchers to (re-)analyze data obtained in (earlier) studies possibly revealing new insights into complex disease states and treatment strategies
