Protein

Kynurenine--oxoglutarate transaminase 3

Gene

KYAT3

Organism

Homo sapiens (Human)

Status

Reviewed-Annotation score: -Experimental evidence at protein levelⁱ

Functionⁱ

Catalyzes the irreversible transamination of the L-tryptophan metabolite L-kynurenine to form kynurenic acid (KA). May catalyze the beta-elimination of S-conjugates and Se-conjugates of L-(seleno)cysteine, resulting in the cleavage of the C-S or C-Se bond (By similarity). Has transaminase activity towards L-kynurenine, tryptophan, phenylalanine, serine, cysteine, methionine, histidine, glutamine and asparagine with glyoxylate as an amino group acceptor (in vitro). Has lower activity with 2-oxoglutarate as amino group acceptor (in vitro) (By similarity).By similarity

Caution

The first non-coding exon of CCBL2 is in common with that of RBMXL1.Curated

Catalytic activityⁱ

L-kynurenine + 2-oxoglutarate = 4-(2-aminophenyl)-2,4-dioxobutanoate + L-glutamate.

An L-cysteine-S-conjugate + H₂O = RSH + NH₃ + pyruvate.

L-kynurenine + glyoxylate = 4-(2-aminophenyl)-2,4-dioxobutanoate + glycine.
