Evidence that the Streptomyces developmental protein WhiD, a member of the WhiB family, binds a 4Fe-4S cluster

WhiD is required for the late stages of sporulation in the Gram-positive bacterium Streptomyces coelicolor. WhiD is a member of the WhiB-like family of putative transcription factors that are present throughout the actinomycetes but absent from other organisms. This family of proteins has four near-invariant cysteines, suggesting that these residues might act as ligands for a metal cofactor. Overexpressed WhiD, purified from Escherichia coli, contained substoichiometric amounts of iron and had an absorption spectrum characteristic of a [2Fe-2S] cluster. After Fe-S cluster reconstitution under anaerobic conditions, WhiD contained similar to4 iron atoms/monomer and similar amounts of sulfide ion and gave an absorption spectrum characteristic of a [4Fe-4S] cluster. Reconstituted WhiD gave no electron paramagnetic resonance signal as prepared but, after reduction with dithionite, gave an electron paramagnetic resonance signal (g similar to2.06, 1.94) consistent with a one-electron reduction of a [4Fe-4S](2+) cluster to a [4Fe-4S](1+) state with electron spin of S = 1/2. The anaerobically reconstituted [4Fe-4S] cluster was oxygen sensitive. Upon exposure to air, absorption at 410 and 505 nm first increased and then showed a steady decrease with time until the protein was colorless in the near UV/visible region. These changes are consistent with an oxygen-induced change from a [4Fe-4S] to a [2Fe-2S] cluster, followed by complete loss of cluster from the protein. Each of the four conserved cysteine residues, Cys-23, -53, -56, and -62, was essential for WhiD function in vivo

Thigh-length compression stockings and DVT after stroke

Controversy exists as to whether neoadjuvant chemotherapy improves survival in patients with invasive bladder cancer, despite randomised controlled trials of more than 3000 patients. We undertook a systematic review and meta-analysis to assess the effect of such treatment on survival in patients with this disease

'Voyaging in': colonialism and migration

A major reference chapter on the history of the literature of colonialism and migration 1945-70. The book marks an intervention into conventional histories of British Literature. The chapter illustrates and analyses the influential formation of alternative modernities by migrant writers resident in Britain during this period; it also extends the gaze to the period before 1945 earlier in the twentieth century. Maps new ways of reading literary history; broad and wideranging discussion of migration during this period

Reservoir quality of Cenozoic carbonate buildups and coral reef terraces

Almost half of SE Asia's considerable hydrocarbon reserves are contained in carbonates. The majority of these reservoirs are Miocene buildups up to tens of kilometres across. However, with the exception of a few fields, there is little detailed data on how local depositional and diagenetic conditions influence the considerable heterogeneities in reservoir quality often encountered. This study focuses on factors influencing the facies, diagenetic and reservoir variability of comparable Modern, Quaternary and Neogene reef associated deposits from the Tukang Besi Archipelago, Central Indonesia.The Archipelago includes large atolls, a number of smaller buildups and 4 main islands each with modern rimmed shelves or fringing reefs. On the islands, over ten late Neogene and Quaternary coral reef terraces have been uplifted to maximum heights of ~300 m. Analysis of the modern deposits allows initial reservoir potential to be assessed and related to local environmental conditions. The influence of diagenesis on final reservoir quality is evaluated for the depositional facies exposed in the uplifted terraces. The overall spatial distribution of effective porosity across the area is strongly dependent on local energy conditions, water depth, carbonate producers, size of atolls or islands, climate and local meteoric diagenetic processes. This evaluation of spatial variability in carbonate reservoir characteristics provides much needed analogue data as the hydrocarbon industry focuses on improving recovery from existing fields and exploring for new reserves
