Cytochrome oxydase
WebHuman cytochrome c oxidase is composed of 13 subunits. The three major subunits form the catalytic core and are encoded by mitochondrial DNA (mtDNA). The remaining subunits are nuclear-encoded. The primary sequence is known for all human subunits and the crystal structure of bovine heart cytochrome c oxidase has recently been reported. WebApr 27, 2007 · Rather, under both 20 and 80% O (2), mitochondrial reactive oxygen species (ROS) production is approximately 2-fold less in HeLa-80 cells, likely related to a significantly higher cytochrome c oxidase (COX) activity ( approximately 2-fold), which may act to deplete upstream electron-rich intermediates responsible for ROS generation.
