Function
CSDA_ECOLI Catalyzes the removal of elemental sulfur and selenium atoms from L-cysteine, L-cystine, L-selenocysteine, and L-selenocystine to produce L-alanine. L-cysteine sulfinic acid is the best substrate. Functions as a selenium delivery protein in the pathway for the biosynthesis of selenophosphate.[1]
Publication Abstract from PubMed
In Escherichia coli, three cysteine desulfurases (IscS, SufS and CsdA) initiate the delivery of sulfur for various biological processes such as the biogenesis of Fe-S clusters. The sulfur generated as persulfide on a cysteine residue of cysteine desulfurases are further transferred to Fe-S scaffolds (e.g. IscU), or to intermediate cysteine-containing sulfur-acceptors (e.g. TusA, SufE, and CsdE) prior to its utilization. Herein, we report structures of CsdA, and CsdA-CsdE complex, which provide insight into the sulfur transfer mediated by the trans-persulfuration reaction. Analysis of the structures indicates that the conformational flexibility of the active cysteine loop in CsdE is essential for accepting the persulfide from the cysteine of CsdA. Additionally, CsdA and CsdE invoke a different binding mode than those of previously reported cysteine desulfurase (IscS) and sulfur-acceptors (TusA and IscU). Moreover, the conservation of interaction-mediating residues between CsdA/SufS and CsdE/SufE further suggests that the SufS-SufE interface likely resembles that of CsdA and CsdE.
