Human Gene OAT (uc001lhp.3)
  Description: Homo sapiens ornithine aminotransferase (OAT), nuclear gene encoding mitochondrial protein, transcript variant 1, mRNA.
RefSeq Summary (NM_000274): This gene encodes the mitochondrial enzyme ornithine aminotransferase, which is a key enzyme in the pathway that converts arginine and ornithine into the major excitatory and inhibitory neurotransmitters glutamate and GABA. Mutations that result in a deficiency of this enzyme cause the autosomal recessive eye disease Gyrate Atrophy. Alternatively spliced transcript variants encoding different isoforms have been described. Related pseudogenes have been defined on the X chromosome. [provided by RefSeq, Jan 2010].

  ID: OAT_HUMAN
DESCRIPTION: RecName: Full=Ornithine aminotransferase, mitochondrial; EC=2.6.1.13; AltName: Full=Ornithine delta-aminotransferase; AltName: Full=Ornithine--oxo-acid aminotransferase; Contains: RecName: Full=Ornithine aminotransferase, hepatic form; Contains: RecName: Full=Ornithine aminotransferase, renal form; Flags: Precursor;
CATALYTIC ACTIVITY: L-ornithine + a 2-oxo acid = L-glutamate 5- semialdehyde + an L-amino acid.
COFACTOR: Pyridoxal phosphate.
PATHWAY: Amino-acid biosynthesis; L-proline biosynthesis; L- glutamate 5-semialdehyde from L-ornithine: step 1/1.
SUBUNIT: Homotetramer.
INTERACTION: P56537:EIF6; NbExp=1; IntAct=EBI-721662, EBI-372243;
SUBCELLULAR LOCATION: Mitochondrion matrix.
DISEASE: Defects in OAT are the cause of hyperornithinemia with gyrate atrophy of choroid and retina (HOGA) [MIM:258870]. HOGA is a slowly progressive blinding autosomal recessive disorder.
SIMILARITY: Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family.

FrontTopSide
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.
