CC -!- FUNCTION: Converts the D-glycero-alpha-D-manno-heptose 1,7-bisphosphate
CC intermediate into D-glycero-alpha-D-manno-heptose 1-phosphate by
CC removing the phosphate group at the C-7 position. {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-glycero-alpha-D-manno-heptose 1,7-bisphosphate + H2O = D-
CC glycero-alpha-D-manno-heptose 1-phosphate + phosphate;
CC Xref=Rhea:RHEA:28522, ChEBI:CHEBI:15377, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:60207, ChEBI:CHEBI:61574; EC=3.1.3.83;
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC -!- PATHWAY: Nucleotide-sugar biosynthesis; GDP-D-glycero-alpha-D-manno-
CC heptose biosynthesis; GDP-D-glycero-alpha-D-manno-heptose from D-
CC glycero-alpha-D-manno-heptose 7-phosphate: step 2/3.
CC -!- PATHWAY: Capsule biogenesis; capsule polysaccharide biosynthesis.
CC -!- SUBUNIT: Monomer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the GmhB family. {ECO:0000305}.
