A NOVEL IRON CENTRE IN THE SPLIT-SORET CYTOCHROME C FROM DESULFOVIBRIO DESULFURICANS ATCC 27774
Overview
The facultative sulfate/nitrate-reducing bacterium Desulfovibrio, desulfuricans ATCC 27774 harbours a split-Soret cytochrome c. This, cytochrome is a homodimeric protein, having two bis-histidinyl c-type, haems per monomer. It has an unique architecture at the haem domain: each, haem has one of the coordinating histidines provided by the other monomer, and in each monomer the haems are parallel to each other, almost in van, der Waals contact. This work reports the cloning and sequencing of the, gene encoding for this cytochrome and shows, by transcriptional analysis, that it is more expressed in nitrate-grown cells than in sulfate-grown, ones. In addition, the gene-deduced amino acid sequence revealed two new, cysteine residues that could be involved in the binding of a non-haem iron, ... [(full description)]
