Description Kynurenine--oxoglutarate aminotransferase
Notes The family is composed by enzymes similar to the prototypical rat kynurenine aminotransferase, but endowed with a broad substrate specificity. For example, the rat kynurenine aminotransferase I also shows alpha-aminoadipate aminotransferase activity ( while the T. thermophilus enzyme has been found responsible for the kynurenine-oxoglutarate aminotransferase reaction and for the glutamine-phenylpyruvate reaction (
The family includes the mammalian proteins earlier termed 'glutamine transaminase K'.
