complejo III de transporte del electrón
complejo del citocromo bc1
ubiquinol-citocromo-C reductasa
Scope note: Complejo enzimático que contiene GRUPO DEL CITOCROMO B, CITOCROMO C1 y centros de hierro-azufre. Cataliza la oxidación del ubiquinol a UBIQUINONA y transfiere los electrones al CITOCROMO C. En la MITOCONDRIA, la reacción redox se asocia al transporte de PROTONES a través de la membrana mitocondrial interna.

Scope note: A multisubunit enzyme complex that contains CYTOCHROME B GROUP; CYTOCHROME C1; and iron-sulfur centers. It catalyzes the oxidation of ubiquinol to UBIQUINONE, and transfers the electrons to CYTOCHROME C. In MITOCHONDRIA the redox reaction is coupled to the transport of PROTONS across the inner mitochondrial membrane.
