CRYSTAL STRUCTURE OF RAT BILIVERDIN REDUCTASE AT 1.4 A
Overview
Biliverdin reductase (BVR) is a soluble cytoplasmic enzyme that catalyzes the conversion of biliverdin to bilirubin using NADH or NADPH as electron donor. Bilirubin is a significant biological antioxidant, but it is also neurotoxic and the cause of kernicterus. In this study, we have determined the crystal structure of rat BVR at 1.4 A resolution. The structure contains two domains: an N-terminal domain characteristic of a dinucleotide binding fold (Rossmann fold) and a C-terminal domain that is predominantly an antiparallel six-stranded beta-sheet. Based on this structure, we propose modes of binding for NAD(P)H and biliverdin, and a possible mechanism for the enzyme.
About this Structure
1GCU is a Single protein structure of sequence from Rattus norvegicus. Active as Biliverdin reductase, with EC number 1.3.1.24 Full crystallographic information is available from OCA.
