CC -!- FUNCTION: Catalyzes the transfer of a two-carbon ketol group from a
CC ketose donor to an aldose acceptor, via a covalent intermediate with
CC the cofactor thiamine pyrophosphate. {ECO:0000256|RuleBase:RU004996}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-glyceraldehyde 3-phosphate + D-sedoheptulose 7-phosphate =
CC aldehydo-D-ribose 5-phosphate + D-xylulose 5-phosphate;

CC Evidence={ECO:0000256|RuleBase:RU004996};
CC Note=Binds 1 Mg(2+) ion per subunit. Can also utilize other divalent
CC metal cations, such as Ca(2+), Mn(2+) and Co(2+).
CC {ECO:0000256|RuleBase:RU004996};
CC -!- COFACTOR:
CC Name=thiamine diphosphate; Xref=ChEBI:CHEBI:58937;
CC Evidence={ECO:0000256|RuleBase:RU004996};
CC Note=Binds 1 thiamine pyrophosphate per subunit.
CC {ECO:0000256|RuleBase:RU004996};
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738,
CC ECO:0000256|RuleBase:RU004996}.
CC -!- SIMILARITY: Belongs to the transketolase family.
CC {ECO:0000256|ARBA:ARBA00007131, ECO:0000256|RuleBase:RU004996}.
