Kynurenine aminotransferases (KATs) are pyridoxal-5’-phosphate-dependent enzymes that catalyze the conversion of L-kynurenine into kynurenic acid, a neuroactive metabolite whose unbalancing is associated with a number of brain disorders. Biochemical and structural investigations revealed that L-kynurenine (L-KYN) recognition by hKAT II is achieved by exploiting structural features that are peculiar of this isoform, thus offering the possibility to select/design inhibitor molecules specifically targeting hKAT II to be used as modulators of kynurenic acid synthesis in the CNS. hKAT II is one of the aminotransferases involved in the pyridoxal 5'-phosphate (PLP)-dependent irreversible transamination of L-kynurenine (L-KYN) to kynurenic acid (KYNA) in the central nervous system. When assayed in vitro the protein also displays beta-elimination activity.
Recombinant protein corresponding to full-length human KAT II, fused to His-tag at N-terminal, expressed in E. coli.
Applications:Suitable for use in testing potential kynurenic acid synthesis inhibitors by performing either in vitro end point assays followed by HPLC-UV or continuous spectrophotometric analysis.
Storage and Stability:Aliquot to avoid repeated freezing and thawing and store at -70°C. Aliquots are stable for 6 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
