背景介绍
Cytochrome C oxidase (COX) is the terminal enzyme of the
mitochondrial respiratory chain. It is a multi-subunit enzyme
complex that couples the transfer of electrons from cytochrome c to
molecular oxygen and contributes to a proton electrochemical
gradient across the inner mitochondrial membrane. The complex
consists of 13 mitochondrial- and nuclear-encoded subunits. The
mitochondrially-encoded subunits perform the electron transfer and
proton pumping activities. The functions of the nuclear-encoded
subunits are unknown but they may play a role in the regulation and
assembly of the complex. This gene encodes the nuclear-encoded
subunit Vb of the human mitochondrial respiratory chain enzyme.

功能
Component of the cytochrome c oxidase, the last enzyme in the mitochondrial electron transport chain which drives oxidative phosphorylation. The respiratory chain contains 3 multisubunit complexes succinate dehydrogenase (complex II, CII), ubiquinol- cytochrome c oxidoreductase (cytochrome b-c1 complex, complex III, CIII) and cytochrome c oxidase (complex IV, CIV), that cooperate to transfer electrons derived from NADH and succinate to molecular oxygen, creating an electrochemical gradient over the inner membrane that drives transmembrane transport and the ATP synthase. Cytochrome c oxidase is the component of the respiratory chain that catalyzes the reduction of oxygen to water. Electrons originating from reduced cytochrome c in the intermembrane space (IMS) are transferred via the dinuclear copper A center (CU(A)) of subunit 2 and heme A of subunit 1 to the active site in subunit 1, a binuclear center (BNC) formed by heme A3 and copper B (CU(B)). The BNC reduces molecular oxygen to 2 water molecules using 4 electrons from cytochrome c in the IMS and 4 protons from the mitochondrial matrix.
