QPRT Recombinant Protein

Source : Escherichia Coli. QPRT Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 317 amino acids (1-297 a.a.) and having a molecular mass of 32.9 kDa. The QPRT is fused to a 20 amino acid His-Tag at N-terminus and purified by proprietary chromatographic techniques. QPRT is a key enzyme in the catabolism of quinolinate. QPRT is in between the tryptophannicotinamide adenine dinucleotide (NAD) pathway, resulting in the production of nicotinic acid, carbon dioxide and pyrophosphate. Rise of QPRT levels in the brain is related to the pathogenesis of neurodegenerative disorders such as epilepsy, Alzheimer's disease, and Huntington''s disease.
