Summary
Enables cysteine-S-conjugate beta-lyase activity and glutamine-phenylpyruvate transaminase activity. Involved in L-kynurenine metabolic process and pyruvate metabolic process. Predicted to be located in cytosol and mitochondrial matrix. Predicted to be active in mitochondrion. Orthologous to human KYAT1 (kynurenine aminotransferase 1).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
