Description
Mitochondrial proton pumps are large enzyme complexes (CI, CII, CIV, CV) spanning the inner mt-membrane, partially encoded by mtDNA. CI, CII and CIV are proton pumps that drive protons against the electrochemical proton motive force, driven by electron transfer from reduced substrates to oxygen. In contrast, CV is a proton pump that utilizes the energy of proton flow along the proton motive force to drive phosphorylation of ADP to ATP.
