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 -!- 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, ECO:0000305}.
