>TIGR01814 kynureninase kynureninase; InterPro: IPR010111 This entry describes kynureninase, it is a pyridoxal-5'-phosphate (PLP)-dependent enzyme that catalyzes the hydrolytic cleavage of L-kynurenine to anthranilic acid and L-alanine. Kynurinine is a Trp breakdown product and a precursor for NAD. This reaction is a key step in the catabolism of L-tryptophan by Pseudomonas fluorescens and some other bacteria (1). In fungi and vertebrates, kynurenine is first hydroxylated to 3-hydroxykynurenine, which is the preferred substrate of kynureninase in those organisms, resulting in 3-hydroxyanthranilate and L-alanine. Sequence alignment with other PLP-dependent enzymes indicated that kynureninase is in subgroup IVa of the aminotransferases, along with nifS, CsdB, and serine-pyruvate aminotransferase, which suggests that kynureninase has an aminotransferase fold .; GO: 0030170 pyridoxal phosphate binding, 0030429 kynureninase activity, 0006569 tryptophan catabolic process, 0009435 NAD biosynthetic process, 0005737 cytoplasm.
