CC -!- FUNCTION: Acts as a sulfur carrier required for molybdopterin
CC biosynthesis. Component of the molybdopterin synthase complex that
CC catalyzes the conversion of precursor Z into molybdopterin by mediating
CC the incorporation of 2 sulfur atoms into precursor Z to generate a
CC dithiolene group. In the complex, serves as sulfur donor by being
CC thiocarboxylated (-COSH) at its C-terminus by UBA4. After interaction
CC with MOCS2B, the sulfur is then transferred to precursor Z to form
CC molybdopterin. {ECO:0000256|HAMAP-Rule:MF_03051}.
CC -!- PATHWAY: Cofactor biosynthesis; molybdopterin biosynthesis.
CC {ECO:0000256|ARBA:ARBA00005046, ECO:0000256|HAMAP-Rule:MF_03051}.
CC -!- SUBUNIT: Heterotetramer; composed of 2 small (MOCS2A) and 2 large
CC (MOCS2B) subunits. {ECO:0000256|HAMAP-Rule:MF_03051}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_03051}.
CC -!- PTM: C-terminal thiocarboxylation occurs in 2 steps, it is first acyl-
CC adenylated (-COAMP) via the hesA/moeB/thiF part of UBA4, then
CC thiocarboxylated (-COSH) via the rhodanese domain of UBA4.
CC {ECO:0000256|HAMAP-Rule:MF_03051}.
CC -!- SIMILARITY: Belongs to the MoaD family. MOCS2A subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_03051}.
CC -!- SIMILARITY: Belongs to the eukaryotic ribosomal protein eS28 family.
CC {ECO:0000256|ARBA:ARBA00005943}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
