    Cytochrome c peroxidase from yeast is a soluble haem-containing protein found in the mitochondrial electron transport chain where it probably protects against toxic peroxides. The aim of this study was to obtain a reliable structure for the doubly oxidized transient intermediate (termed compound I) in the reaction of cytochrome c peroxidase with hydrogen peroxide. This intermediate contains a semistable free radical on Trp191, and an oxyferryl haem group.
