CC   -!- FUNCTION: Catalyzes the isomerization of sedoheptulose 7-phosphate in
CC       D-glycero-D-manno-heptose 7-phosphate. {ECO:0000255|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; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00067};
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00067};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000255|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:0000255|HAMAP-Rule:MF_00067}.
CC   -!- PATHWAY: Bacterial outer membrane biogenesis; LOS core biosynthesis.
CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_00067}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|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:0000255|HAMAP-Rule:MF_00067}.
CC   -!- SIMILARITY: Belongs to the SIS family. GmhA subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_00067}.
