EC 2.8.1.11 Details
EC number
2.8.1.11
Accepted name
molybdopterin synthase sulfurtransferase
Reaction
[molybdopterin-synthase sulfur-carrier protein]-Gly-Gly-AMP + [cysteine desulfurase]-S-sulfanyl-L-cysteine + reduced acceptor = AMP + [molybdopterin-synthase sulfur-carrier protein]-Gly-NH-CH2-C(O)SH + [cysteine desulfurase]-L-cysteine + oxidized acceptor
Other name(s)
adenylyltransferase and sulfurtransferase MOCS3, Cnx5 (gene name), molybdopterin synthase sulfurylase
Systematic name
[cysteine desulfurase]-S-sulfanyl-L-cysteine:[molybdopterin-synthase sulfur-carrier protein]-Gly-Gly sulfurtransferase
Comment
The enzyme transfers sulfur to form a thiocarboxylate moiety on the C-terminal glycine of the small subunit of EC 2.8.1.12, molybdopterin synthase. In the human, the reaction is catalysed by the rhodanese-like C-terminal domain (cf. EC 2.8.1.1) of the MOCS3 protein, a bifunctional protein that also contains EC 2.7.7.80, molybdopterin-synthase adenylyltransferase, at the N-terminal domain.
