General description
L-lysine contains basic side chain and is hydrophilic in nature. The N-butyl amino group in the side chain is found to be protonated at physiological pH. Upon degradation, L-lysine gives ketone bodies. Transamination of lysine with α-ketoglutarate produces acetoacetyl CoA. L-lysine serves as a precursor for secondary metabolites, such as β-lactam antibiotics. It also serves as a precursor for the biosynthesis of α-aminoadipic acid.
Application
L-Lysine is an essential proteinogenic α amino acid used in a wide range of applications. It has been used:
- as a supplement in cell culture media
- as a substrate for enzymes such as L-lysine oxidase (EC 1.4.3.14)
- as a component of poly-lysine polymers
- as a substrate for oxidation and glycation mechanism studies
- in the preparation of cobaltous lysine

In beta-lactam producing microorganisms, the first step in the biosynthesis of the beta-lactam ring is the condensation of three amino acid precursors: alpha-aminoadipate, L-cysteine and D-valine. In Nocardia lactamdurans and other cephamycin-producing actinomycetes, alpha-aminoadipate is generated from L-lysine by two
