Descrição: Activators: Papain is activated by cysteine, sulphide, sulphite and more. It is enhanced when heavy metal binding agents such as EDTA are also present. N-bromosuccinimide enhances the activity. Inhibitors: Substances which react with sulphydryl groups including heavy metals, carbonyl reagents. Aldehydes are papain inhibitors. Benzoylamidoacetonitrile is an inhibitor. See Shapira and Arnon (1967a and b) on antibody inhibitors. Papain may be inactivated by H₂O₂ generated by γ-irradiation of H₂O⁻ the active SH group being oxidised to sulphenic acid. Specific inhibitors are AEBSF, antipain, cystatin, E-64, leupeptin, PMSF, TLCK and TPCK.

Descrição: Human nicotinate phosphoribosyltransferase (NAPRTase) is localised in the cytoplasm and is involved in biological processes such as NAD biosynthetic and metabolic processes, nicotinamide metabolic process, nicotinate nucleotide salvage, response to oxidative stress and water-soluble vitamin metabolic process. It functions by catalyzing the conversion of nicotinic acid (NA) to NA mononucleotide (NaMN) and is essential for NA to increase cellular NAD levels and prevent oxidative stress of the cells. It is a crucial factor in the NAD+ biosynthesis pathway. Catalytic activity: Beta-nicotinate D-ribonucleotide + diphosphate = nicotinate + 5-phospho-alpha-D-ribose 1-diphosphate.

Descrição: Kynurenine aminotransferases (KATs) are pyridoxal-5’-phosphate-dependent enzymes that catalyse 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.
