Enzyme Information
| 2.5.1.113 |
[CysO sulfur-carrier protein]-thiocarboxylate-dependent cysteine synthase.
based on mapping to UniProt P9WP53
O-phospho-L-serine + [CysO sulfur-carrier protein]-Gly-NH-CH(2)-C(O)SH = [CysO sulfur-carrier protein]-Gly-NH-CH(2)-C(O)-S-L-cysteine + phosphate.
-!- The enzyme participates in an alternative pathway for L-cysteine biosynthesis that involves a protein-bound thiocarboxylate as the sulfide donor. -!- The enzyme from the bacterium Mycobacterium tuberculosis also has very low activity with O(3)-acetyl-L-serine (cf. EC 2.5.1.65). -!- Formerly EC 2.5.1.n5.
