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