Enzyme Information

2.8.1.7
Cysteine desulfurase.
based on mapping to UniProt O32164
L-cysteine + acceptor = L-alanine + S-sulfanyl-acceptor.
-!- The sulfur from free L-cysteine is first transferred to a cysteine residue in the active site, and then passed on to various other acceptors. -!- The enzyme is involved in the biosynthesis of iron-sulfur clusters, thio-nucleosides in tRNA, thiamine, biotin, lipoate and pyranopterin (molybdopterin). -!- In Azotobacter vinelandii, this sulfur provides the inorganic sulfide required for nitrogenous metallocluster formation.
