ID 2.8.1.11 DE molybdopterin synthase sulfurtransferase. AN molybdopterin synthase sulfurylase. CA [molybdopterin-synthase sulfur-carrier protein]-C-terminal Gly-Gly-AMP + CA AH2 + S-sulfanyl-L-cysteinyl-[cysteine desulfurase] = [molybdopterin- CA synthase sulfur-carrier protein]-C-terminal Gly-NH-CH2-C(O)SH + A + AMP + CA H(+) + L-cysteinyl-[cysteine desulfurase]. CC -!- The enzyme transfers sulfur to form a thiocarboxylate moiety on the CC C-terminal glycine of the small subunit of EC 2.8.1.12. CC -!- In the human, the reaction is catalyzed by the rhodanese-like CC C-terminal domain (cf. EC 2.8.1.1) of the MOCS3 protein, CC a bifunctional protein that also contains EC 2.7.7.80 at the CC N-terminal domain. CC -!- Formerly EC 2.8.1.n1.
