citocromo-c oxidasa
complejo IV del transporte de electrones
Scope note: Complejo enzimático con múltiples subunidades que contiene el GRUPO CITOCROMO A, el CITOCROMO A3, dos átomos de cobre y 13 subunidades proteicas diferentes. Es el complejo oxidasa terminal de la CADENA RESPIRATORIA y recoge electrones que son transferidos desde el GRUPO DEL CITOCROMO C reducido, que los cede al OXÍGENO molecular, que es reducido entonces dando lugar a agua. La reacción redox se asocia de manera simultánea al transporte de PROTONES a través de la membrana mitocondrial interna.

Scope note: A multisubunit enzyme complex containing CYTOCHROME A GROUP; CYTOCHROME A3; two copper atoms; and 13 different protein subunits. It is the terminal oxidase complex of the RESPIRATORY CHAIN and collects electrons that are transferred from the reduced CYTOCHROME C GROUP and donates them to molecular OXYGEN, which is then reduced to water. The redox reaction is simultaneously coupled to the transport of PROTONS across the inner mitochondrial membrane.
