KEGG ENZYME: 2.2.1.3

ENZYME: 2.2.1.3

Entry

EC 2.2.1.3                  Enzyme

Name

formaldehyde transketolase;
dihydroxyacetone synthase

Class

Transferases;
Transferring aldehyde or ketonic groups;
Transketolases and transaldolases

Sysname

D-xylulose-5-phosphate:formaldehyde glycolaldehydetransferase

Reaction(IUBMB)

D-xylulose 5-phosphate + formaldehyde = D-glyceraldehyde 3-phosphate + glycerone [RN:R01440]

Reaction(KEGG)

R01440;
(other) R06861 R06862

Substrate

D-xylulose 5-phosphate [CPD:C00231];
formaldehyde [CPD:C00067]

Product
