Enzyme Information
| 2.6.1.1 |
Aspartate transaminase.
based on mapping to UniProt P00508
L-aspartate + 2-oxoglutarate = oxaloacetate + L-glutamate.
-!- Also acts on L-tyrosine, L-phenylalanine and L-tryptophan. -!- This activity can be formed from EC 2.6.1.57 by controlled proteolysis.
|
| 2.6.1.7 |
Kynurenine--oxoglutarate transaminase.
based on mapping to UniProt P00508
L-kynurenine + 2-oxoglutarate = 4-(2-aminophenyl)-2,4-dioxobutanoate + L-glutamate.
-!- Also acts on 3-hydroxykynurenine. -!- The product 4-(2-aminophenyl)-2,4-dioxobutanoate is converted into kynurenate by a spontaneous reaction.
