Enzyme Information

2.2.1.1
Transketolase.
based on mapping to UniProt P23254
Sedoheptulose 7-phosphate + D-glyceraldehyde 3-phosphate = D-ribose 5-phosphate + D-xylulose 5-phosphate.
-!- Wide specificity for both reactants, e.g. converts hydroxypyruvate and R-CHO into CO(2) and R-CHOH-CO-CH(2)OH. -!- The enzyme from the bacterium Alcaligenes faecalis shows high activity with D-erythrose 4-phosphate as acceptor.
