Comments
[?]
| FUNCTION | Transfers a GMP moiety from GTP to Mo-molybdopterin (Mo-MPT) cofactor (Moco or molybdenum cofactor) to form Mo-molybdopterin guanine dinucleotide (Mo-MGD) cofactor. |
| CATALYTIC ACTIVITY | Reaction=Mo-molybdopterin + GTP + H(+) = Mo-molybdopterin guanine dinucleotide + diphosphate; Xref=Rhea:RHEA:34243, ChEBI:CHEBI:15378, ChEBI:CHEBI:33019, ChEBI:CHEBI:37565, ChEBI:CHEBI:71302, ChEBI:CHEBI:71310; EC=2.7.7.77; |
| COFACTOR | Name=Mg(2+); Xref=ChEBI:CHEBI:18420; |
| case <OC:Pseudomonadota> | |
| SUBUNIT | Monomer. |
| end case | |
| DOMAIN | The N-terminal domain determines nucleotide recognition and specific binding, while the C-terminal domain determines the specific binding to the target protein. |
| SUBCELLULAR LOCATION | Cytoplasm. |
| SIMILARITY | Belongs to the MobA family. |
