4-hydroxy-tetrahydrodipicolinate reductase

Template:Short description Template:Infobox enzyme In enzymology, a 4-hydroxy-tetrahydrodipicolinate reductase (Template:EC number) is an enzyme that catalyzes the chemical reaction

(S)-2,3,4,5-tetrahydropyridine-2,6-dicarboxylate + NAD(P)⁺ + H₂O $\rightleftharpoons$ (2S,4S)-4-hydroxy-2,3,4,5-tetrahydrodipicolinate + NAD(P)H + H⁺

The 3 substrates of this enzyme are (S)-2,3,4,5-tetrahydropyridine-2,6-dicarboxylate, NAD⁺ or NADP⁺, and H₂O, whereas its 3 products are (2S,4S)-4-hydroxy-2,3,4,5-tetrahydrodipicolinate, NADH or NADPH, and H⁺.

This enzyme participates in lysine biosynthesis.

Nomenclature

This enzyme belongs to the family of oxidoreductases, specifically those acting on CH or CH₂ groups with NAD⁺ or NADP⁺ as acceptor. The systematic name of this enzyme class is (S)-2,3,4,5-tetrahydropyridine-2,6-dicarboxylate:NAD(P)+ 4-oxidoreductase. Other names in common use include:

• dihydrodipicolinate reductase,
• dihydrodipicolinic acid reductase, and
• 2,3,4,5-tetrahydrodipicolinate:NAD(P)+ oxidoreductase.
