My passion for extreme conditions to solve the cytochrome P450 and NO synthase reaction mechanisms
Cytochrome P450, and especially its reaction mechanism, has always been a major research interest of Professor I.C. Gunsalus. The reaction cycle of this enzyme is complex, containing many elementary steps and intermediates, and constitutes a challenge for the scientific community. During his repeated stays in our laboratories in Paris and in Montpellier, he contributed decisively to our study of the P450 reaction mechanism under extreme conditions, i.e., at subzero temperatures and at high pressure. From this initial impulse. we continued the work with different forms of cytochrome P450 and later on with nitric oxide synthase. This paper gives an overview of the insights into these enzymes gained by the use of extreme conditions. These exciting achievements were initiated by numerous discussions with Professor Gunsalus and also reflect a long-lasting collaboration and friendship. (C) 2003 Elsevier Inc. All rights reserved.
