CC -!- FUNCTION: Converts molybdopterin precursor Z into molybdopterin. This
CC requires the incorporation of two sulfur atoms into precursor Z to
CC generate a dithiolene group. The sulfur is provided by MoaD (By
CC similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 [molybdopterin-synthase sulfur-carrier protein]-C-terminal
CC Gly-NH-CH2-C(O)SH + cyclic pyranopterin phosphate + H2O = 2
CC [molybdopterin-synthase sulfur-carrier protein]-C-terminal Gly-Gly +
CC 4 H(+) + molybdopterin; Xref=Rhea:RHEA:26333, Rhea:RHEA-COMP:12160,

CC ChEBI:CHEBI:90778; EC=2.8.1.12;
CC -!- PATHWAY: Cofactor biosynthesis; molybdopterin biosynthesis.
CC -!- SUBUNIT: Heterotetramer of 2 MoaD subunits and 2 MoaE subunits. Also
CC stable as homodimer. The enzyme changes between these two forms during
CC catalysis (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the MoaE family. {ECO:0000305}.
