ENZYME: 2.2.1.11

Entry

EC 2.2.1.11                 Enzyme

Name

6-deoxy-5-ketofructose 1-phosphate synthase;
DKFP synthase

Class

Transferases;
Transferring aldehyde or ketonic groups;
Transketolases and transaldolases

Sysname

2-oxopropanal:D-fructose 1,6-bisphosphate glycerone-phosphotransferase

Reaction(IUBMB)

(1) 2-oxopropanal + D-fructose 1,6-bisphosphate = D-glyceraldehyde 3-phosphate + 1-deoxy-D-threo-hexo-2,5-diulose 6-phosphate [RN:R10049];
(2) 2-oxopropanal + D-fructose 1-phosphate = D-glyceraldehyde + 1-deoxy-D-threo-hexo-2,5-diulose 6-phosphate [RN:R10050]

Reaction(KEGG)

R10049 R10050

Substrate

2-oxopropanal [CPD:C00546];
D-fructose 1,6-bisphosphate [CPD:C00354];
D-fructose 1-phosphate [CPD:C01094]

Product

D-glyceraldehyde 3-phosphate [CPD:C00118];
1-deoxy-D-threo-hexo-2,5-diulose 6-phosphate [CPD:C16848];
D-glyceraldehyde [CPD:C00577]

Comment

The enzyme plays a key role in an alternative pathway of the biosynthesis of 3-dehydroquinate (DHQ), which is involved in the canonical pathway for the biosynthesis of aromatic amino acids. The enzyme can also catalyse the reaction of EC 4.1.2.13, fructose-bisphosphate aldolase.
