Abstract Background OleP is a cyt P450 from Streptomyces antibioticus carrying out epoxigenation of the antibiotic oleandomycin during its biosynthesis. The timing of its reaction has not been fully clarified, doubts remain regarding its substrate and catalytic mechanis...

Abstract Background Glutathione transferases (GSTs) are a family of detoxification enzymes that catalyze the conjugation of glutathione (GSH) to electrophilic compounds. Methods A library of alpha class GSTs was constructed by DNA shuffling using the DNA encoding the hu...

article Background: Chloroplasts were formed by uptake of cyanobacteria into eukaryotic cells ca. 1.6 billion years ago. During evolution most of the cyanobacterial genes were transferred from the chloroplast to the nuclear genome. The rbcX gene, encoding an assembly ch...

Abstract Background In-cell NMR is a powerful technique to investigate proteins in living human cells at atomic resolution. Ideally, when studying functional processes involving protein–protein interactions by NMR, only one partner should be isotopically labeled. Here w...

Abstract Background In Gram-negative bacteria the ZnuABC transporter ensures adequate zinc import in Zn(II)-poor environments, like those encountered by pathogens within the infected host. Recently, the metal-binding protein ZinT was suggested to operate as an accessory...

Members of the monothiol glutaredoxin family and members of the BolA-like protein family have recently emerged as specific interacting partners involved in iron-sulfur protein maturation and redox regulation pathways. It is known that human mitochondrial BOLA1 and BOLA3...
