Similar to other cytochromec peroxidases, they reduce hydrogen peroxide to water using c type haem as an oxidizable Enzyme substrate substrate . However, since they possess two, instead of one, haem prosthetic groups , this family of bacteria bacterial CCPs reduce hydrogen peroxide without the need to generate semi stable free radical s. The two haem groups have significantly different redox potentials. The high potential 320 mV haem feeds electron s from electron shuttle protein s to the low potential 330 mV haem, where peroxide is Redox reduced indeed, the low potential site is known as the peroxidatic site . ref name pmid8591033 cite journal author Fulop V, Ridout CJ, Greenwood C, Hajdu J title Crystal structure of the di haem cytochromec peroxidase from Pseudomonas aeruginosa journal Structure volume 3 issue 11 pages 1225 33 year 1995 month November pmid 8591033 doi url ref The CCP protein itself is structured into two domains, each containing one c type haem group, with a calcium binding site at the domain interface.
