Substrates: the bifunctional reductase/saccharopine dehydrogenase contains the first two enzyme of lysine catabolism, is concertedly regulated by metabolic and stress-associated signals. The level of the bifunctional enzyme is strongly enhanced by abscisic acid, jasmonate, and sugar starvation, whereas excess sugars and nitrogen starvation reduce its level

Substrates: the bifunctional enzyme lysine-ketoglutarate reductase/saccharopine dehydrogenase (LKR/SDH) comprises a LKR domain, which condenses lysine and 2-oxoglutarate into saccharopine, and the SDH domain, that hydrolyzes saccharopine to form glutamate and alpha-aminoadipate semialdehyde, the latter of which is oxidized to alpha-aminoadipate by aminoadipate semialdehyde dehydrogenase (AASADH). Monofunctional SDH has also been found in animals and in Arabidopsis thaliana
