Other name(s): kynurenine transaminase (cyclizing); kynurenine 2-oxoglutarate transaminase; kynurenine aminotransferase; L-kynurenine aminotransferase
Systematic name: L-kynurenine:2-oxoglutarate aminotransferase
Comments: A pyridoxal-phosphate protein. Also acts on 3-hydroxykynurenine. The product 4-(2-aminophenyl)-2,4-dioxobutanoate is converted into kynurenate by a spontaneous reaction.
