Function and Biology Details

Reactions catalysed: 
L-2-aminoadipate + 2-oxoglutarate = 2-oxoadipate + L-glutamate
Glycine + 2-oxoglutarate = glyoxylate + L-glutamate
(1a) L-kynurenine + glyoxylate = 4-(2-aminophenyl)-2,4-dioxobutanoate + glycine 
(1a) L-kynurenine + 2-oxoglutarate = 4-(2-aminophenyl)-2,4-dioxobutanoate + L-glutamate
L-methionine + glyoxylate = 4-methylthio-2-oxobutanoate + glycine
