Cytochrome c oxidase is an enzyme that:

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. WebIt has been almost 5 years since the first structures of cytochrome c oxidase, from Paracoccus denitrificans and bovine heart mitochondria, were revealed. Since then many different proton pumping mechanisms have been proposed for the enzyme; however, no definitive conclusion has been achieved. In this article, we revisit the original structures ...

WebAbstract. The intricate biogenesis of multimeric organellar enzymes of dual genetic origin entails several levels of regulation. In Saccharomyces cerevisiae, mitochondrial cytochrome c oxidase (COX) assembly is regulated translationally. Synthesis of subunit 1 (Cox1) is contingent on the availability of its assembly partners, thereby acting as ... WebInhibition of this enzyme results in the collapse of the mitochondrial membrane potential, disruption of pyrimidine biosynthesis, and subsequent parasite death. Resistance to atovaquone in the field is associated with point mutations in the Q(o) pocket of cytochrome b, most notably near the conserved Pro(260)-Glu(261)-Trp(262)-Tyr(263) (PEWY ...
