L lysine lactamase

In enzymology, a L-lysine-lactamase (EC 3.5.2.11) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are L-lysine 1,6-lactam and H₂O, whereas its product is L-lysine.

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in cyclic amides. The systematic name of this enzyme class is L-lysine-1,6-lactam lactamhydrolase. Other names in common use include L-alpha-aminocaprolactam hydrolase, and L-lysinamidase.
