Sysname
L-aspartate 4-semialdehyde:1-deoxy-D-threo-hexo-2,5-diulose 6-phosphate methylglyoxaltransferase
Reaction(IUBMB)
L-aspartate 4-semialdehyde + 1-deoxy-D-threo-hexo-2,5-diulose 6-phosphate = 2-amino-3,7-dideoxy-D-threo-hept-6-ulosonate + 2,3-dioxopropyl phosphate [RN:
R08568 ]
Reaction(KEGG)
Substrate
L-aspartate 4-semialdehyde [CPD:
C00441 ];
1-deoxy-D-threo-hexo-2,5-diulose 6-phosphate [CPD:
C16848 ]
Product
2-amino-3,7-dideoxy-D-threo-hept-6-ulosonate;
2,3-dioxopropyl phosphate [CPD:
C16849 ]
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.
History
EC 2.2.1.10 created 2012
Pathway
ec00400 Phenylalanine, tyrosine and tryptophan biosynthesis
ec01110 Biosynthesis of secondary metabolites
Orthology
