Human Kynurenine Aminotransferase I in complex with Glycerol

Released:

Function and Biology Details

Reactions catalysed:
L-glutamine + phenylpyruvate = 2-oxoglutaramate + L-phenylalanine
(1a) L-kynurenine + 2-oxoglutarate = 4-(2-aminophenyl)-2,4-dioxobutanoate + L-glutamate
(1a) an L-cysteine-S-conjugate = a thiol + 2-aminoporp-2-enoate
