REDUCED SOXAX COMPLEX FROM RHODOVULUM SULFIDOPHILUM
OverviewOverview
Reduced inorganic sulfur compounds are utilized by many bacteria as, electron donors to photosynthetic or respiratory electron transport, chains. This metabolism is a key component of the biogeochemical sulfur, cycle. The SoxAX protein is a heterodimeric c-type cytochrome involved in, thiosulfate oxidation. The crystal structures of SoxAX from the, photosynthetic bacterium Rhodovulum sulfidophilum have been solved at 1.75, A resolution in the oxidized state and at 1.5 A resolution in the, dithionite-reduced state, providing the first structural insights into the, enzymatic oxidation of thiosulfate. The SoxAX active site contains a haem, with unprecedented cysteine persulfide (cysteine sulfane) coordination., This unusual post-translational modification is also seen in, sulfurtransferases ...
