TMLD is an alias for the gene, Trimethyllysine hydroxylase, epsilon, in humans. Other names include: Trimethyllysine dioxygenase, mitochondrial; Epsilon-trimethyllysine hydroxylase; TML hydroxylase; TML-alpha-ketoglutarate dioxygenase; TML dioxygenase; Epsilon-trimethyllysine 2-oxoglutarate dioxygenase; Trimethyllysine dioxygenase, mitochondrial ; butyrobetaine (gamma), 2-oxoglutarate dioxygenase (gamma-butyrobetaine hydroxylase) 2; AUTSX6; BBOX2; TMLH; TMLHED; XAP130. The encoded protein is an enzyme with an amino acid length of 421 and a mass of 49.5 kDa. Other isoforms may exist. TMLD is a member of the Gamma-BBH/TMLD family. This gene shares homology with other species, including: Mouse, Rat, Zebrafish, Frog, Chicken.
