摘要

In mammals, heme is degraded to biliverdin by heme oxygenase (HO) and subsequently, the biliverdin is reduced to bilirubin by biliverdin reductase (BVR). The metabolic waste product, bilirubin is now becoming recognized as having functional importance. It appears to play a key role in oxidative stress defense in vivo. Thus, heme degradation pathway has seen renewed interest in its biosynthesis. Recently, the X-ray crystal structures of HO and BVR were determined. Based on the structures, new insights into the mechanism of the heme degradation and bilirubin synthesis are discussed.
