Function
function
Catalyzes the conversion of 4-hydroxy-tetrahydrodipicolinate (HTPA) to tetrahydrodipicolinate.
Catalytic activity
- (S)-2,3,4,5-tetrahydrodipicolinate + H2O + NAD+ = (2S,4S)-4-hydroxy-2,3,4,5-tetrahydrodipicolinate + H+ + NADH
Pathway
Amino-acid biosynthesis; L-lysine biosynthesis via DAP pathway; (S)-tetrahydrodipicolinate from L-aspartate: step 4/4.
