title: NO news is good news.
abstract: The recent determination of the crystal structure of microsomal cytochrome P450 reductase, a diflavin protein that shuttles electrons from NADPH to the P450 heme, represents a significant advance towards the understanding of cytochromes P450. A similar advance was made in a related enzyme system, nitric oxide synthase (NOS). The crystal structure of the NOS heme domain reveals a very different architecture to that observed in P450s and offers significant insight into the production of nitric oxide, one of nature's most important regulatory molecules.
