CC -!- FUNCTION: Catalytic subunit of the molybdopterin synthase complex, a
CC complex that catalyzes the conversion of precursor Z into
CC molybdopterin. Acts by mediating the incorporation of 2 sulfur atoms
CC from thiocarboxylated MOCS2A into precursor Z to generate a dithiolene
CC group. {ECO:0000255|HAMAP-Rule:MF_03052}.
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; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_03052};
CC -!- PATHWAY: Cofactor biosynthesis; molybdopterin biosynthesis.
CC {ECO:0000255|HAMAP-Rule:MF_03052}.
CC -!- SUBUNIT: Heterotetramer; composed of 2 small (MOCS2A) and 2 large
CC (MOCS2B) subunits. {ECO:0000255|HAMAP-Rule:MF_03052}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03052}.
CC -!- SIMILARITY: Belongs to the MoaE family. MOCS2B subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_03052}.
