  • Function

    Catalyzes the conversion of gamma-aminobutyrate and L-beta-aminoisobutyrate to succinate semialdehyde and methylmalonate semialdehyde, respectively. Can also convert delta-aminovalerate and beta-alanine.
  • Tissue specificity

    Liver > pancreas > brain > kidney > heart > placenta.
  • Involvement in disease

    Defects in ABAT are a cause of gamma-aminobutyrate transaminase deficiency (GABA-AT deficiency) [MIM:613163]. The phenotype of this deficiency includes psychomotor retardation, hypotonia, hyperreflexia, lethargy, refractory seizures, and EEG abnormalities.
  • Sequence similarities

    Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family.
  • Cellular localization

    Mitochondrion matrix.
