HUMAN BILIVERDIN IX BETA REDUCTASE: NADP COMPLEX

OverviewOverview

Biliverdin IXbeta reductase (BVR-B) catalyzes the pyridine, nucleotide-dependent production of bilirubin-IXbeta, the major heme, catabolite during early fetal development. BVR-B displays a preference for, biliverdin isomers without propionates straddling the C10 position, in, contrast to biliverdin IXalpha reductase (BVR-A), the major form of BVR in, adult human liver. In addition to its tetrapyrrole clearance role in the, fetus, BVR-B has flavin and ferric reductase activities in the adult. We, have solved the structure of human BVR-B in complex with NADP+ at 1.15 A, resolution. Human BVR-B is a monomer displaying an alpha/beta dinucleotide, binding fold. The structures of ternary complexes with mesobiliverdin, IValpha, biliverdin IXalpha, FMN and lumichrome show that human BVR-B has, a ... [(full description)]
