CC Evidence={ECO:0000256|HAMAP-Rule:MF_01225};
CC Note=Binds 2 [4Fe-4S] clusters. Binds 1 [4Fe-4S] cluster coordinated
CC with 3 cysteines and an exchangeable S-adenosyl-L-methionine and 1
CC [4Fe-4S] cluster coordinated with 3 cysteines and the GTP-derived
CC substrate. {ECO:0000256|HAMAP-Rule:MF_01225};
CC -!- PATHWAY: Cofactor biosynthesis; molybdopterin biosynthesis.
CC {ECO:0000256|HAMAP-Rule:MF_01225}.
CC -!- SUBUNIT: Monomer and homodimer. {ECO:0000256|HAMAP-Rule:MF_01225}.
CC -!- SIMILARITY: Belongs to the radical SAM superfamily. MoaA family.
CC {ECO:0000256|HAMAP-Rule:MF_01225}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
