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 RHEA:34243: GTP + H(+) + Mo-molybdopterin = diphosphate + Mo-molybdopterin guanine dinucleotide
EC 2.7.7.77
Cofactor Mg(2+)
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.
