CC -!- FUNCTION: Nucleoside diphosphate sugar hydrolase that hydrolyzes GDP-
CC mannose as its preferred substrate, yielding GMP and mannose-1-
CC phosphate. {ECO:0000250|UniProtKB:P37128}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=GDP-alpha-D-mannose + H2O = alpha-D-mannose 1-phosphate + GMP
CC + 2 H(+); Xref=Rhea:RHEA:27978, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:57527, ChEBI:CHEBI:58115, ChEBI:CHEBI:58409;
CC Evidence={ECO:0000250|UniProtKB:P37128};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:P37128};
CC -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:P37128}.
CC -!- DOMAIN: In the dimer, the N-terminal domains are swapped between the
CC two monomers, such that residues of both chains contribute to the
CC active site. {ECO:0000250|UniProtKB:P37128}.
CC -!- SIMILARITY: Belongs to the Nudix hydrolase family. NudK subfamily.
CC {ECO:0000305}.
