EC 2.2.1.11     
Accepted name: 6-deoxy-5-ketofructose 1-phosphate synthase
Reaction: (1) 2-oxopropanal + D-fructose 1,6-bisphosphate = D-glyceraldehyde 3-phosphate + 1-deoxy-D-threo-hexo-2,5-diulose 6-phosphate
(2) 2-oxopropanal + D-fructose 1-phosphate = D-glyceraldehyde + 1-deoxy-D-threo-hexo-2,5-diulose 6-phosphate

Glossary: 2-oxopropanal = methylglyoxal
1-deoxy-D-threo-hexo-2,5-diulose 6-phosphate = 6-deoxy-5-ketofructose 1-phosphate
Other name(s): DKFP synthase
Systematic name: 2-oxopropanal:D-fructose 1,6-bisphosphate glycerone-phosphotransferase
Comments: 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.
