Comments [?]

FUNCTION	dGTPase preferentially hydrolyzes dGTP over the other canonical NTPs.
CATALYTIC ACTIVITY	Reaction=dGTP + H2O = 2'-deoxyguanosine + triphosphate + H(+); Xref=Rhea:RHEA:15193, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:17172, ChEBI:CHEBI:18036, ChEBI:CHEBI:61429; EC=3.1.5.1;
COFACTOR	Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
case <OC:Enterobacterales>
SUBUNIT	Homotetramer.
end case
SIMILARITY	Belongs to the dGTPase family. Type 1 subfamily.
case not <OC:Enterobacterales>
CAUTION	As this bacterium is not an Enterobacterale, this protein may not have a true dGTPase activity.
