CC -!- FUNCTION: Transfers a GMP moiety from GTP to Mo-molybdopterin (Mo-MPT)
CC cofactor (Moco or molybdenum cofactor) to form Mo-molybdopterin guanine
CC dinucleotide (Mo-MGD) cofactor. {ECO:0000255|HAMAP-Rule:MF_00316}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=GTP + H(+) + Mo-molybdopterin = diphosphate + Mo-molybdopterin
CC guanine dinucleotide; Xref=Rhea:RHEA:34243, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:33019, ChEBI:CHEBI:37565, ChEBI:CHEBI:71302,
CC ChEBI:CHEBI:71310; EC=2.7.7.77; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00316};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00316};
CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_00316}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00316}.
CC -!- DOMAIN: The N-terminal domain determines nucleotide recognition and
CC specific binding, while the C-terminal domain determines the specific
CC binding to the target protein. {ECO:0000255|HAMAP-Rule:MF_00316}.
CC -!- SIMILARITY: Belongs to the MobA family. {ECO:0000255|HAMAP-
CC Rule:MF_00316}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAA70754.1; Type=Erroneous initiation; Evidence={ECO:0000305};
