シトクロムc
Cytochrome c oxidase subunit 6B1 is an enzyme that in humans is encoded by the "COX6B1" gene. Cytochrome "c" oxidase 6B1 is a subunit of the cytochrome "c" oxidase complex, also known as Complex IV, the last enzyme in the mitochondrial electron transport chain. Mutations of the COX6B1 gene are associated with severe infantile encephalomyopathy and mitochondrial complex IV deficiency (MT-C4D).
