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.
gollark: We even have an automatic power plant control system. If someone ctrl-t's the program to edit the code without flipping the manual control to off it could even melt!
gollark: Compromise: the power plant itself is TMI. The island is sheep island or whatever.
gollark: Ten Metre Island is online though not actually sending power anywhere.
gollark: * most
gollark: If I had immersive engineering we would have bauxite. I didn't add it, though.
