| lysine | <amino acid> The only carrier of a side chain primary amino group in proteins. Has important structural and chemical roles in proteins. (18 Nov 1997) |
| lysine carboxypeptidase | <enzyme> A serine carboxypeptidase that removes c-terminal amino acids, preferentially lysine, from peptides and proteins. It inactivates bradykinin by this action. Registry number: EC 3.4.17.3 (12 Dec 1998) |
| lysine decarboxylase | <enzyme> Do not confuse with cada atpase Registry number: EC 4.1.1.18 Synonym: cad a gene product, cada lysine decarboxylase (26 Jun 1999) |
| lysine epsilon-dehydrogenase | <enzyme> From agrobacterium tumefaciens; forms alpha-aminoadipate delta-saemialdehyde which is spontaneously converted to delta 1-piperideine-6-carboxylate Registry number: EC 1.4.1.- Synonym: l-lysine epsilon-dehydrogenase (26 Jun 1999) |
| lysine monooxygenase | <enzyme> Minor descriptor (75-82); online and index medicus search oxygenases (75-82) Registry number: EC 1.13.12.2 Synonym: lysine oxygenase (26 Jun 1999) |
| lysine N-epsilon hydroxylase | <enzyme> Do not confuse with lysine hydroxylase, which forms 5-hydroxylysine Registry number: EC 1.14.13.- Synonym: n-epsilon lysine monooxygenase, iucd protein, aera protein, lysine n(6)-hydroxylase (26 Jun 1999) |
| lysine racemase | <enzyme> Interconverts the d- and l-isomers Registry number: EC 5.1.1.5 (26 Jun 1999) |

| lysine-p-nitroanilide hydrolase | <enzyme> Hydrolyses a wide variety of di-, tri-, and tetrapeptides, and polypeptides up to 15 amino acids; it is blocked only if proline is in the penultimate position from n-terminus or if n-terminus is blocked, e.g. Pyroglutamyl residue Registry number: EC 3.4.- Synonym: lysine-4-nitroanilide hydrolase, lys-pna hydrolase (26 Jun 1999) |
| lysine-trna ligase | <enzyme> An enzyme that activates lysine with its specific transfer RNA. Chemical name: L-Lysine:tRNA(Lys) ligase (AMP-forming) Registry number: EC 6.1.1.6 (12 Dec 1998) |
| lysinium | The cation form of lysine, either lysinium (+1) or lysinium (+2). (05 Mar 2000) |
| lysinoalanine | <chemical> N(6)-(2-amino-2-carboxyethyl)-l-lysine. An unusual amino acid, not a dipeptide, which has been found in proteins of cooked foods. It is formed in food that is heated or treated with alkali. Has been implicated in nephrocytomegalia in rats. Chemical name: L-Lysine, N6-(2-amino-2-carboxyethyl)- (12 Dec 1998) |
