swb1
Description Beta-hydroxykynurenine aminotransferase (2.6.1.-)
Catalyzed reaction Beta-hydroxy-L-kynurenine + 2-oxoglutarate = 3,4-dihydroxyquinoline-2-carboxylate + L-glutamate
Cofactor Pyridoxal phosphate
The enzyme is not to be confused with 3-hydroxykynurenine aminotransferase (QbsB).

The immediate keto product of the reaction, 4-(2-amino phenyl)-3-hydroxy 2,4-dioxobutanoate, is converted into 3,4-dihydroxyquinoline-2-carboxylate by a spontaneous reaction.
