CC   -!- FUNCTION: Transaldolase is important for the balance of metabolites in
CC       the pentose-phosphate pathway. {ECO:0000255|HAMAP-Rule:MF_00492}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=D-glyceraldehyde 3-phosphate + D-sedoheptulose 7-phosphate =
CC         beta-D-fructose 6-phosphate + D-erythrose 4-phosphate;
CC         Xref=Rhea:RHEA:17053, ChEBI:CHEBI:16897, ChEBI:CHEBI:57483,
CC         ChEBI:CHEBI:57634, ChEBI:CHEBI:59776; EC=2.2.1.2;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00492};
CC   -!- PATHWAY: Carbohydrate degradation; pentose phosphate pathway; D-
CC       glyceraldehyde 3-phosphate and beta-D-fructose 6-phosphate from D-
CC       ribose 5-phosphate and D-xylulose 5-phosphate (non-oxidative stage):
CC       step 2/3. {ECO:0000255|HAMAP-Rule:MF_00492}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00492}.
CC   -!- SIMILARITY: Belongs to the transaldolase family. Type 1 subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_00492}.
