Descriptor

citocromos

Scope note:

Hemoproteínas cuyo característico modo de acción entraña la transferencia de equivalentes reductores asociados a un cambio reversible en el estado de oxidación del grupo prostético. Formalmente, este cambio redox implica el equilibrio reversible de un solo electrón entre los estados de Fe(II) y Fe(III) del átomo central de hierro. (Enzyme Nomenclature, 1992, p539). Las distintas subclases de citocromos se organizan según el tipo de HEMO y el rango de la longitud de onda de sus bandas de absorción alfa reducidas.

Scope note:

Hemeproteins whose characteristic mode of action involves transfer of reducing equivalents which are associated with a reversible change in oxidation state of the prosthetic group. Formally, this redox change involves a single-electron, reversible equilibrium between the Fe(II) and Fe(III) states of the central iron atom (From Enzyme Nomenclature, 1992, p539). The various cytochrome subclasses are organized by the type of HEME and by the wavelength range of their reduced alpha-absorption bands.
