Common NameN6,N6,N6-Trimethyl-L-lysine
DescriptionN6,N6,N6-Trimethyl-L-lysine, also known as epsilon-N-trimethyl-L-lysine or delta-trimethyllysine, belongs to the class of organic compounds known as l-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. Mitochondrial 6-N-N6,N6,N6-Trimethyl-L-lysine dioxygenase converts 6-N-N6,N6,N6-Trimethyl-L-lysine to 3-hydroxy-6-N-N6,N6,N6-Trimethyl-L-lysine as the first step for carnitine biosynthesis. It is a component of histone proteins, a precursor of carnitine and a coenzyme of fatty acid oxidation. N6,N6,N6-Trimethyl-L-lysine is a very strong basic compound (based on its pKa). N6,N6,N6-Trimethyl-L-lysine exists in all living organisms, ranging from bacteria to humans. Within humans, N6,N6,N6-trimethyl-L-lysine participates in a number of enzymatic reactions. In particular, N6,N6,N6-trimethyl-L-lysine and S-adenosylhomocysteine can be biosynthesized from L-lysine and S-adenosylmethionine; which is mediated by the enzyme histone-lysine N-methyltransferase SETD7. In addition, N6,N6,N6-trimethyl-L-lysine and oxoglutaric acid can be converted into 3-hydroxy-N6,N6,N6-trimethyl-L-lysine and succinic acid through its interaction with the enzyme trimethyllysine dioxygenase, mitochondrial. In humans, N6,N6,N6-trimethyl-L-lysine is involved in carnitine synthesis. N6,N6,N6-Trimethyl-L-lysine was first documented in 1979 (PMID: 454517). When N6,N6,N6-Trimethyl-L-lysine is released from cognate proteins via proteolysis, it serves as a precursor for carnitine biosynthesis (PMID: 3111294) (PMID: 2106342) (PMID: 3093513) (PMID: 3136187).
