This view shows enzymes only for those organisms listed below, in the list of taxa known to possess the pathway. If an enzyme name is shown in bold, there is experimental evidence for this enzymatic activity.

In this pathway, L-lysine is converted to (S)-2-amino-6-oxohexanoate by L-lysine 6-aminotransferase. (S)-2-amino-6-oxohexanoate is subsequently cyclized by spontaneous intramolecular dehydration to 1-piperideine 6-carboxylate [Soda68, Tanizawa85, Fujii00a].
This enzymatic activity has been shown in the γ-proteobacterium Flavobacterium lutescens IFO3084 (previously known as Achromobacter liquidum) [Tanizawa85] and in the actinomycete Streptomyces clavuligerus.
Further catabolism of L-2-aminoadipate in [Flavobacterium] lutescens has not been described although in some other γ-proteobacteria it is catabolized to glutarate (see MetaCyc pathway L-lysine degradation V).
Iin Streptomyces clavuligerus L-2-aminoadipate is a precursor of β-lactam antibiotics and is a substrate for δ-(L-α-aminoadipyl)-L-cysteinyl-D-valine synthetase (see isopenicillin N biosynthesis) [deLa97].
