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}.
