General annotation (Comments)

Function

Catalyzes the conversion of 4-hydroxy-tetrahydrodipicolinate (HTPA) to tetrahydrodipicolinate By similarity. HAMAP-Rule MF_00102 SAAS SAAS023940

Catalytic activity

(S)-2,3,4,5-tetrahydropyridine-2,6-dicarboxylate + NAD(P)+ + H2O = (2S,4S)-4-hydroxy-2,3,4,5-tetrahydrodipicolinate + NAD(P)H + H+. HAMAP-Rule MF_00102 SAAS SAAS023940

Pathway

Amino-acid biosynthesis; L-lysine biosynthesis via DAP pathway; (S)-tetrahydrodipicolinate from L-aspartate: step 4/4. HAMAP-Rule MF_00102 SAAS SAAS023940

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_00102 SAAS SAAS023940.

Sequence similarities

Belongs to the DapB family. HAMAP-Rule MF_00102

Caution

Was originally thought to be a dihydrodipicolinate reductase (DHDPR), catalyzing the conversion of dihydrodipicolinate to tetrahydrodipicolinate. However, it was shown in E.coli (PubMed:20503968) that the substrate of the enzymatic reaction is not dihydrodipicolinate (DHDP) but in fact (2S,4S)-4-hydroxy-2,3,4,5-tetrahydrodipicolinic acid (HTPA), the product released by the DapA-catalyzed reaction.
