L-Lysine is an essential proteinogenic α amino acid used in a wide range of applications including as a supplement in cell culture media; a substrate of enzymes such as L-lysine oxidase (EC 1.4.3.14); a component of poly-lysine polymers; and a substrate for oxidation and glycation mechanism studies.

The melanogenic marine bacterium M. mediterranea synthesizes marinocine, a protein with antibacterial activity. We cloned the gene coding for this protein and named it lodA [P. Lucas-Elío, P. Hernández, A. Sanchez-Amat, F. Solano, Purification and partial characterization of marinocine, a

A sensitive and reliable LC-(ESI)MS/MS method was developed and validated for the simultaneous analysis of five common advanced glycation endproducts (AGEs) after enzymatic digestion in raw and roasted almonds. AGEs included carboxymethyl-lysine (CML), carboxyethyl-lysine (CEL), pyralline (Pyr), argpyrimidine (Arg-p), and

We investigated the antioxidant and anti-inflammatory activities of both crude and ultrafiltrated Maillard reaction (MR) products (MRPs) derived from sugar-amino acid MR models, comprising fructose (Fru), glucose (Glu) or ribose (Rib) reacted with glycine (Gly) or lysine (Lys), respectively. Crude

Serum protein glycation and formation of advanced glycation endproducts (AGE) correlates with diabetic complications. Highly AGE-modified albumin is frequently used to study the biochemical and cellular activities of AGE-proteins. However, moderately modified albumin samples are expected to be (patho)physiologically more

L-lysine (L-Lys) in living bodies is critical for metabolism; therefore, determination of its levels in food is important. Most enzymatic methods for L-Lys analysis are performed using L-lysine oxidase (LyOx), but commercially manufactured LyOx is generally not highly selective for
