Description
QDPR Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 267 amino acids (1-244 a.a.) and having a molecular mass of 28.2kDa.QDPR is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Additional Information
IntroductionQDPR belongs to the short-chain dehydrogenases/reductase (SDR) family of enzymes. Operating as a homodimer, QDPR has an imperative role in the recycling of tetrahydrobiopterin (BH4), a vital cofactor for the hydroxylation of the aromatic amino acids (tryptophan, tyrosine and phenylalanine). More precisely, QDPR catalyzes the regeneration of BH4 from quinonoid dihydrobiopterin (qBH2), the product generated from the hydroxylation reactions. Mutations in the QDPR gene may lead to phenylketonuria II.
SynonymsDihydropteridine reductase, HDHPR, Quinoid dihydropteridine reductase, QDPR, DHPR, PKU2, SDR33C1.
