生化/生理作用
Biliverdin reductase catalyzes the transformation of the blue-green pigment biliverdin IX to the yellow-orange bile pigment bilirubin IX by converting a double-bond between the second and third pyrrole ring into a single-bond. This enzyme has two distinct cofactor-dependent pH optima. In the acidic range of pH 6.0-6.7, NADH is utilized, whereas in the alkaline range of pH 8.5-8.7, NADPH is utilized. Biliverdin reductase is considered a major physiologic cytoprotectant. Biliverdin reductase suppresses experimental autoimmune encephalomyelitis in rats. Depletion of biliverdin reductase leads to accumulation of cellular oxidants and augmented cell death.
单位定义
