EC 1.5.1.9     
Accepted name: saccharopine dehydrogenase (NAD+, L-glutamate-forming)
Reaction: N6-(L-1,3-dicarboxypropyl)-L-lysine + NAD+ + H2O = L-glutamate + (S)-2-amino-6-oxohexanoate + NADH + H+
Glossary: saccharopine = N6-(L-1,3-dicarboxypropyl)-L-lysine
(S)-2-amino-6-oxohexanoate = L-2-aminoadipate 6-semialdehyde = L-allysine
Other name(s): dehydrogenase, saccharopine (nicotinamide adenine dinucleotide, glutamate-forming); saccharopin dehydrogenase; NAD+ oxidoreductase (L-2-aminoadipic-δ-semialdehyde and glutamate forming); aminoadipic semialdehyde synthase; 6-N-(L-1,3-dicarboxypropyl)-L-lysine:NAD+ oxidoreductase (L-glutamate-forming)
Systematic name: N6-(L-1,3-dicarboxypropyl)-L-lysine:NAD+ oxidoreductase (L-glutamate-forming)
Comments: The activities of this enzyme along with EC 1.5.1.8, saccharopine dehydrogenase (NADP+, L-lysine-forming), occur on a single protein.
