Accepted name: [CysO sulfur-carrier protein]-S-L-cysteine hydrolase
Reaction: [CysO sulfur-carrier protein]-Gly-NH-CH2-C(O)-S-L-cysteine + H2O = [CysO sulfur-carrier protein]-Gly-NH-CH2-COOH + L-cysteine
Other name(s): mec (gene name)
Systematic name: [CysO sulfur-carrier protein]-S-L-cysteine sulfohydrolase
Comments: Requires Zn2+. The enzyme, characterized from the bacterium Mycobacterium tuberculosis, participates in an L-cysteine biosynthesis pathway. It acts on the product of EC, [CysO sulfur-carrier protein]-thiocarboxylate-dependent cysteine synthase.
