متن کاملStudies on Cytochrome c Peroxidase
Apoproteins of cytochrome c peroxidase, horseradish peroxidase, and sperm whale myoglobin were recombined with manganese complexes of proto-, hemato-, meso-, and deuteroporphyrins to form manganese porphyrin-protein complexes. These complexes were purified by column chromatography. All the manganese porphyrin-containing cytochrome c peroxidases were crystallized. Light absorption maxima of mang...
متن کاملEffect of specific lysine modification on the reduction of cytochrome c by succinate-cytochrome c reductase.
The reduction of cytochrome c by succinate-cytochrome c reductase was studied at very low cytochrome c concentrations where the reaction between cytochrome c1 and cytochrome c was rate limiting. The rate constant for the reaction was found to be independent of ionic strength up to 0.1 M chloride, and to decrease rapidly at higher ionic strength, suggesting that the interaction between cytochrom...
متن کاملPeroxidase activity enhancement of horse cytochrome c by dimerization.
The peroxidase activity of horse cytochrome c was enhanced by its dimerization, where its Compound III (oxy-form) and Compound I (oxoferryl porphyrin π-cation radical) species were detected in the reactions with hydrogen peroxide and meta-chloroperbenzoic acid, respectively. These results show that oligomeric cytochrome c can contribute as a proapoptotic conformer by the increased peroxidase ac...
متن کاملThe crystal structure of cytochrome c peroxidase.
The three-dimensional conformation of yeast cytochrome c peroxidase has been determined from a 2.5 A electron density map computed with phases obtained from two isomorphous mercury derivatives. Partial sequence information that has recently become available aided in completion of the tracing of the polypeptide backbone, confirmed the presence of a proximal histidine heme ligand and aided in ide...
