CC -!- FUNCTION: Catalyzes the isomerization of sedoheptulose 7-phosphate in
CC D-glycero-D-manno-heptose 7-phosphate. {ECO:0000256|HAMAP-
CC Rule:MF_00067}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 D-sedoheptulose 7-phosphate = D-glycero-alpha-D-manno-
CC heptose 7-phosphate + D-glycero-beta-D-manno-heptose 7-phosphate;
CC Xref=Rhea:RHEA:27489, ChEBI:CHEBI:57483, ChEBI:CHEBI:60203,
CC ChEBI:CHEBI:60204; EC=5.3.1.28;
CC Evidence={ECO:0000256|ARBA:ARBA00000348, ECO:0000256|HAMAP-
CC Rule:MF_00067};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00067};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000256|HAMAP-Rule:MF_00067};
CC -!- PATHWAY: Carbohydrate biosynthesis; D-glycero-D-manno-heptose 7-
CC phosphate biosynthesis; D-glycero-alpha-D-manno-heptose 7-phosphate and
CC D-glycero-beta-D-manno-heptose 7-phosphate from sedoheptulose 7-
CC phosphate: step 1/1. {ECO:0000256|HAMAP-Rule:MF_00067}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496,
CC ECO:0000256|HAMAP-Rule:MF_00067}.
CC -!- MISCELLANEOUS: The reaction produces a racemic mixture of D-glycero-
CC alpha-D-manno-heptose 7-phosphate and D-glycero-beta-D-manno-heptose 7-
CC phosphate. {ECO:0000256|HAMAP-Rule:MF_00067}.
CC -!- SIMILARITY: Belongs to the SIS family. GmhA subfamily.
CC {ECO:0000256|ARBA:ARBA00009894, ECO:0000256|HAMAP-Rule:MF_00067}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
