WebFeb 27, 1998 · (1) Cytochrome c released from the inner mitochondrial membrane to the intermembrane space can operate as an enzyme oxidizing O2.- back to O2. The reduced cytochrome c is oxidized by cytochrome oxidase (or in yeasts and bacteria, by cytochrome c peroxidase). WebComplex IV, or cytochrome c oxidase (COX), is the terminal enzyme of the mitochondrial respiratory chain that catalyzes oxidation of cytochrome c by molecular oxygen. The C12ORF62 protein is required for COX assembly ( Weraarpachai et al., 2012 ).
WebPurification of cytochrome c oxidase was carried out from the purified mitochondria by using combination techniques of detergent solubilization and reduced cytochrome c-agarose affinity chromatography. The 560-fold purified enzyme with 3.6% yield was obtained and it had low catalytic efficiency with a kcat/Km of 5.9 x 10(-5) M-1 x min-1. The ...
