Function
function
Catalyzes the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate.
Catalytic activity
- D-sedoheptulose 7-phosphate + D-glyceraldehyde 3-phosphate = aldehydo-D-ribose 5-phosphate + D-xylulose 5-phosphate
Cofactor
Protein has several cofactor binding sites:
Ca2+ (UniProtKB | Rhea| CHEBI:29108 )
Mn2+ (UniProtKB | Rhea| CHEBI:29035 )
Co2+ (UniProtKB | Rhea| CHEBI:48828 )
Note: Binds 1 Mg2+ ion per subunit. Can also utilize other divalent metal cations, such as Ca2+, Mn2+ and Co2+.
Note: Binds 1 thiamine pyrophosphate per subunit.
