L-Lysine degradation is varied among microorganisms, animals and plants. Although many initiating reactions have been studied, in some organisms not all subsequent reactions have been described. Initiating reactions include: decarboxylase (EC 126.96.36.199) in MetaCyc pathway L-lysine degradation I; saccharopine dehydrogenase (EC 188.8.131.52) in L-lysine degradation XI (mammalian); ε-N-acetylase (EC 184.108.40.206) in L-lysine degradation III; lysine 2-monooxygenase (EC 220.127.116.11) in L-lysine degradation IV; racemase (EC 18.104.22.168) in L-lysine degradation V; ε-transaminase (EC 22.214.171.124) in L-lysine degradation VI; α-oxidase (EC 126.96.36.199) in L-lysine degradation VII; ε-dehydrogenase (EC 188.8.131.52) in L-lysine degradation VIII; aminomutase (anaerobic) (EC 184.108.40.206) in L-lysine fermentation to acetate and butanoate; and a novel ε-transaminase (EC 220.127.116.11) in L-lysine degradation IX. Reviewed in [Zabriskie00].
Common intermediates leading to central metabolism include: (S)-2-amino-6-oxohexanoate/ 1-piperideine 6-carboxylate; 2-keto-6-aminocaproate/ 1-piperideine-2-carboxylate; L-2-aminoadipate; 2-oxoadipate; 5-aminopentanoate; glutarate semialdehyde; and glutarate.
In addition, a L-lysine 6-monooxygenase (EC 18.104.22.168) is involved in aerobactin bioxynthesis (see MetaCyc pathway aerobactin biosynthesis). An enzyme in human liver catalyzing the deamination of the lysine α-amino group, L-lysine 2-dehydrogenase (EC 22.214.171.124), was suggested by an early paper [Burgi66] but was not subsequently verified (in [Heydari04]).
