Function

Aminotransferase or transaminase catalyze the reversible exchange of amino group of an amino acid with a keto group of an alpha-keto acid. Aminotransferases use pyridoxal phosphate (PLP) as cofactor.

Histidinol-phosphate aminotransferase (HPA) catalyzes the interconversion of L-histidinol phosphate and 2-oxoglutarate to L-glutarate and 3-(imidazole-4-yl)-2-oxopropyl phosphate. HPA is part of the metabolism of histidine, phenylalanine and tyrosine. ^[1]

Gamma-aminobutyrate aminotransferase (GABA) catalyzes the intercorversion of 4-aminobutanoate and 2-oxoglutarate to succinate semialdehyde and L-glutamate.

Aspartate aminotransferase (AAT) catalyzes the intercorversion of aspartate and α-ketoglutarate to oxaloacetate and glutamate. For details on AAT see Aspartate Aminotransferase.^[2]

Phosphoserine aminotransferase (PSAT) catalyzes the intercorversion of phosphoserine and oxoglutarate to phosphonooxypyruvate and glutamate. For details on PSAT see Phosphoserine aminotransferase.^[3]

Alanine glyoxylate aminotransferase (AGA) catalyzes the intercorversion of alanine and glyoxate to methyloxopropanoate and glycine.

D-amino acid aminotransferase (AAT) catalyzes the intercorversion of D-alanine and oxoglutarate to pyruvate and D-glutamate.

Aromatic amino acid aminotransferase (AROAT) catalyzes the intercorversion of aromatic amino acid and oxoglutarate to aromatic oxo acid and glutamate.

Lysine aminotransferase (LYSAT) catalyzes the intercorversion of lysine and oxoglutarate to aminoadipate semialdeyde and glutamate.

Relevance

Elevated levels of alanine aminotransferase and aspartate aminotransferase are indicators of liver damage.
