CC -!- FUNCTION: In the cytoplasm, catalyzes the conversion of glucose-6-
CC phosphate to fructose-6-phosphate, the second step in glycolysis, and
CC the reverse reaction during gluconeogenesis.
CC {ECO:0000250|UniProtKB:P06744}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=alpha-D-glucose 6-phosphate = beta-D-fructose 6-phosphate;
CC Xref=Rhea:RHEA:11816, ChEBI:CHEBI:57634, ChEBI:CHEBI:58225;
CC EC=5.3.1.9; Evidence={ECO:0000250|UniProtKB:P06744};
CC -!- PATHWAY: Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-
CC phosphate and glycerone phosphate from D-glucose: step 2/4.
CC {ECO:0000305}.
CC -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:P06744}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol
CC {ECO:0000250|UniProtKB:P78917}.
CC -!- SIMILARITY: Belongs to the GPI family. {ECO:0000305}.
