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:0000255|HAMAP-Rule:MF_01225};
CC   -!- PATHWAY: Cofactor biosynthesis; molybdopterin biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_01225}.
CC   -!- SUBUNIT: Monomer and homodimer. {ECO:0000255|HAMAP-Rule:MF_01225}.
CC   -!- SIMILARITY: Belongs to the radical SAM superfamily. MoaA family.
