ID:TMLH_HUMAN DESCRIPTION: RecName: Full=Trimethyllysine dioxygenase, mitochondrial; EC=1.14.11.8; AltName: Full=Epsilon-trimethyllysine 2-oxoglutarate dioxygenase; AltName: Full=Epsilon-trimethyllysine hydroxylase; AltName: Full=TML hydroxylase; AltName: Full=TML-alpha-ketoglutarate dioxygenase; Short=TML dioxygenase; Short=TMLD; Flags: Precursor; FUNCTION: Converts trimethyllysine (TML) into hydroxytrimethyllysine (HTML). CATALYTIC ACTIVITY: N(6),N(6),N(6)-trimethyl-L-lysine + 2- oxoglutarate + O(2) = 3-hydroxy-N(6),N(6),N(6)-trimethyl-L-lysine + succinate + CO(2). COFACTOR: Binds 1 Fe(2+) ion per subunit (By similarity). COFACTOR: Ascorbate. PATHWAY: Amine and polyamine biosynthesis; carnitine biosynthesis. SUBUNIT: Homodimer (By similarity). SUBCELLULAR LOCATION: Mitochondrion matrix. TISSUE SPECIFICITY: All isoforms, but isoform 8, are widely expressed in adult and fetal tissues. Isoform 8 is restricted to heart and skeletal muscle. DISEASE: Defects in TMLHE are the cause of epsilon-trimethyllysine hydroxylase deficiency (TMLHED) [MIM:300872]. An inborn error of carnitine biosynthesis associated with an increased risk for developing autistic behavior. Autism is a complex multifactorial, pervasive developmental disorder characterized by impairments in reciprocal social interaction and communication, restricted and stereotyped patterns of interests and activities, and the presence of developmental abnormalities by 3 years of age. Most individuals with autism also manifest moderate mental retardation. SIMILARITY: Belongs to the gamma-BBH/TMLD family.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
