Functioni

Catalyzes the condensation of (S)-aspartate-beta-semialdehyde [(S)-ASA] and pyruvate to 4-hydroxy-tetrahydrodipicolinate (HTPA).UniRule annotation

Catalytic activityi

Pyruvate + L-aspartate-4-semialdehyde = (4S)-4-hydroxy-2,3,4,5-tetrahydro-(2S)-dipicolinate + H2O.UniRule annotation

Pathwayi: L-lysine biosynthesis via DAP pathway

This protein is involved in step 3 of the subpathway that synthesizes (S)-tetrahydrodipicolinate from L-aspartate.UniRule annotation
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. Aspartokinase (lysC)
  2. Aspartate-semialdehyde dehydrogenase (asd)
  3. 4-hydroxy-tetrahydrodipicolinate synthase (dapA)
  4. 4-hydroxy-tetrahydrodipicolinate reductase (dapB)

Caution

Was originally thought to be a dihydrodipicolinate synthase (DHDPS), catalyzing the condensation of (S)-aspartate-beta-semialdehyde [(S)-ASA] and pyruvate to dihydrodipicolinate (DHDP). However, it was shown in E.coli that the product of the enzymatic reaction is not dihydrodipicolinate but in fact (4S)-4-hydroxy-2,3,4,5-tetrahydro-(2S)-dipicolinic acid (HTPA), and that the consecutive dehydration reaction leading to DHDP is not spontaneous but catalyzed by DapB.Curated

100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
