LP200265-9   3-Hydroxytrimethyl-L-lysine
3-Hydroxytrimethyl-L-lysine is found within the Lysine degradation (aka L-carnitine biosynthesis) pathway; it is a byproduct of trimethyllysine dioxygenase (trimethyllysine hydroxylase, EC 1.14.11.8), which converts trimethyllysine + 2-oxoglutarate to 3-Hydroxytrimethyl-L-lysine + succinate. Patients with X-linked trimethyllysine hydroxylase (TMLHE) deficiency, a carnitine deficiency disorder associated with autism, have lower than expected levels of carnitine as well as 3-Hydroxytrimethyl-L-lysine, and elevated levels of trimethyllysine.

LP200451-5   Trimethyllysine
Trimethyllysine (N6,N6,N6-Trimethyl-L-lysine) is a methylated derivative of the amino acid lysine. It is a component of histone proteins, a precursor of carnitine and a coenzyme of fatty acid oxidation. N6,N6,N6-Trimethyl-L-lysine residues are found in a number of proteins and are generated by the action of S-adenosyl-L-methionine on exposed lysine residues. When trimethyllysine is released from cognate proteins via proteolysis, it serves as a precursor for carnitine biosynthesis. Mitochondrial 6-N-trimethyllysine dioxygenase converts 6-N-trimethyllysine to 3-hydroxy-6-N-trimethyllysine as the first step for carnitine biosynthesis. Because the subsequent carnitine biosynthesis enzymes are cytosolic, 3-hydroxy-6-N-trimethyllysine must be transported out of the mitochondria by a putative mitochondrial 6-N-trimethyllysine/3-hydroxy-6-N-trimethyllysine transporter system. Plasma -N-trimethyllysine concentrations are significantly lower in systemic carnitine deficiency patients compared to normal individuals, but no significant difference in urinary -N-trimethyllysine excretion is seen between the two groups.[HMDB ID: HMDB01325] Copyright Copyright ©2005-2009 Genome Alberta (Reference to original publication: Wishart DS, Knox C, Guo AC, et al.
