CCBL1 Catalyzes the irreversible transamination of the L-tryptophan metabolite L-kynurenine to form kynurenic acid (KA). Metabolizes the cysteine conjugates of certain halogenated alkenes and alkanes to form reactive metabolites. Catalyzes 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. Belongs to the class-I pyridoxal-phosphate-dependent aminotransferase family. 3 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
