CC   -!- FUNCTION: Catalyzes the irreversible transamination of the L-tryptophan
CC       metabolite L-kynurenine to form kynurenic acid (KA), an intermediate in
CC       the tryptophan catabolic pathway which is also a broad spectrum
CC       antagonist of the three ionotropic excitatory amino acid receptors
CC       among others. May catalyze the beta-elimination of S-conjugates and Se-
CC       conjugates of L-(seleno)cysteine, resulting in the cleavage of the C-S
CC       or C-Se bond. Has transaminase activity towards L-kynurenine,
CC       tryptophan, phenylalanine, serine, cysteine, methionine, histidine,
CC       glutamine and asparagine with glyoxylate as an amino group acceptor (in
CC       vitro). Has lower activity with 2-oxoglutarate as amino group acceptor
CC       (in vitro). {ECO:0000250|UniProtKB:Q71RI9}.
