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

Cofactor

Protein has several cofactor binding sites:
Ca2+ (UniProtKB | Rhea| CHEBI:29108 )

Co2+ (UniProtKB | Rhea| CHEBI:48828 )

Mg2+ (UniProtKB | Rhea| CHEBI:18420 )

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+.
thiamine diphosphate (UniProtKB | Rhea| CHEBI:58937 )

Note: Binds 1 thiamine pyrophosphate per subunit.
