Metabolite Identification
Common NameD-Lysine
DescriptionL-lysine, also known as (S)-2,6-diaminohexanoic acid or lysine acid, is a member of the class of compounds known as L-alpha-amino acids. L-alpha-amino acids are alpha amino acids which have the L-configuration of the alpha-carbon atom. L-lysine is soluble (in water) and a moderately acidic compound (based on its pKa). L-lysine can be found primarily in most biofluids, including feces, urine, cerebrospinal fluid (CSF), and sweat, as well as throughout all human tissues. Within the cell, L-lysine is primarily located in the cytoplasm, in the mitochondria, in the nucleus and in the peroxisome. It can also be found in the extracellular space. L-lysine exists in all living species, ranging from bacteria to humans. In humans, L-lysine is involved in several metabolic pathways, some of which include pyridoxine dependency with seizures, carnitine synthesis, lysine degradation, and transcription/Translation. L-lysine is also involved in several metabolic disorders, some of which include 2-aminoadipic 2-oxoadipic aciduria, glutaric aciduria type I, biotinidase deficiency, and hyperlysinemia II or saccharopinuria. Moreover, L-lysine is found to be associated with hyperdibasic aminoaciduria I, cystinuria, tyrosinemia I, and propionic acidemia. L-lysine is a non-carcinogenic (not listed by IARC) potentially toxic compound. Common posttranslational modifications include methylation of the ε-amino group, giving methyl-, dimethyl-, and trimethyllysine (the latter occurring in calmodulin); also acetylation, sumoylation, ubiquitination, and hydroxylation – producing the hydroxylysine in collagen and other proteins. O-Glycosylation of hydroxylysine residues in the endoplasmic reticulum or Golgi apparatus is used to mark certain proteins for secretion from the cell. In opsins like rhodopsin and the visual opsins (encoded by the genes OPN1SW, OPN1MW, and OPN1LW), retinaldehyde forms a Schiff base with a conserved lysine residue, and interaction of light with the retinylidene group causes signal transduction in color vision (See visual cycle for details). Deficiencies may cause blindness, as well as many other problems due to its ubiquitous presence in proteins (Wikipedia). Proteins of the herpes simplex virus are rich in L-arginine, and tissue culture studies indicate an enhancing effect on viral replication when the amino acid ratio of L-arginine to L-lysine is high in the tissue culture media. When the ratio of L-lysine to L-arginine is high, viral replication and the cytopathogenicity of herpes simplex virus have been found to be inhibited. L-lysine may facilitate the absorption of calcium from the small intestine (DrugBank). Chronically high levels of lysine are associated with at least 5 inborn errors of metabolism including: D-2-Hydroxyglutaric Aciduria, Familial Hyperlysinemia I, Hyperlysinemia II, Pyruvate carboxylase deficiency and Saccharopinuria (T3DB). L-lysine is an essential amino acid. Normal requirements for lysine have been found to be about 8 g per day or 12 mg/kg in adults. Children and infants need more, 44 mg/kg per day for an eleven to-twelve-year old, and 97 mg/kg per day for three-to six-month old. Lysine is highly concentrated in muscle compared to most other amino acids. Lysine is high in foods such as wheat germ, cottage cheese and chicken. Of meat products, wild game and pork have the highest concentration of lysine. Fruits and vegetables contain little lysine, except avocados. Normal lysine metabolism is dependent upon many nutrients including niacin, vitamin B6, riboflavin, vitamin C, glutamic acid and iron. Excess arginine antagonizes lysine. Several inborn errors of lysine metabolism are known, such as cystinuria, hyperdibasic aminoaciduria I, lysinuric protein intolerance, propionic acidemia, and tyrosinemia I. Most are marked by mental retardation with occasional diverse symptoms such as absence of secondary sex characteristics, undescended testes, abnormal facial structure, anemia, obesity, enlarged liver and spleen, and eye muscle imbalance. Lysine also may be a useful adjunct in the treatment of osteoporosis. Although high protein diets result in loss of large amounts of calcium in urine, so does lysine deficiency. Lysine may be an adjunct therapy because it reduces calcium losses in urine. Lysine deficiency also may result in immunodeficiency. Requirements for this amino acid are probably increased by stress. Lysine toxicity has not occurred with oral doses in humans. Lysine dosages are presently too small and may fail to reach the concentrations necessary to prove potential therapeutic applications. Lysine metabolites, amino caproic acid and carnitine have already shown their therapeutic potential. Thirty grams daily of amino caproic acid has been used as an initial daily dose in treating blood clotting disorders, indicating that the proper doses of lysine, its precursor, have yet to be used in medicine. Low lysine levels have been found in patients with Parkinson's, hypothyroidism, kidney disease, asthma and depression. The exact significance of these levels is unclear, yet lysine therapy can normalize the level and has been associated with improvement of some patients with these conditions. Abnormally elevated hydroxylysines have been found in virtually all chronic degenerative diseases and coumadin therapy. The levels of this stress marker may be improved by high doses of vitamin C. Lysine is particularly useful in therapy for marasmus (wasting) and herpes simplex. It stops the growth of herpes simplex in culture, and has helped to reduce the number and occurrence of cold sores in clinical studies. Dosing has not been adequately studied, but beneficial clinical effects occur in doses ranging from 100 mg to 4 g a day. Higher doses may also be useful, and toxicity has not been reported in doses as high as 8 g per day. Diets high in lysine and low in arginine can be useful in the prevention and treatment of herpes. Some researchers think herpes simplex virus is involved in many other diseases related to cranial nerves such as migraines, Bell's palsy and Meniere's disease. Herpes blister fluid will produce fatal encephalitis in the rabbit (http://www.dcnutrition.com)..
