Function[CCPR_YEAST] Destroys radicals which are normally produced within the cells and which are toxic to biological systems. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe ferryl [Fe(IV)O] intermediate is important in many heme enzymes, and thus, the precise nature of the Fe(IV)-O bond is critical in understanding enzymatic mechanisms. The 1.40 A crystal structure of cytochrome c peroxidase Compound I has been determined as a function of X-ray dose while the visible spectrum was being monitored. The Fe-O bond increases in length from 1.73 A in the low-X-ray dose structure to 1.90 A in the high-dose structure. The low-dose structure correlates well with an Fe(IV) horizontal lineO bond, while we postulate that the high-dose structure is the cryo-trapped Fe(III)-OH species previously thought to be an Fe(IV)-OH species.
