Studies on cytochrome c oxidase activity of the cytochrome c1aa3 complex from Thermus thermophilus.
Cytochrome oxidase from T. thermophilus is isolated as a noncovalent complex of cytochromes c1 and aa3 in which the four redox components of aa3 appear to be associated with a single approximately 55,000-D subunit while the heme C is associated with a approximately 33,000-D peptide (Yoshida, T., Lorence, R. M., Choc, M. G., Tarr, G. E., Findling, K. L., and Fee, J. A. (1983) J. Biol. Chem. 258,...
متن کاملThe biometric and cytochrome oxidase subunit I (COI) gene sequence analysis of syngnathus abaster (Teleostei: Syngnathidae) in Caspian sea
The black-striped pipefish, Syngnathus abaster, is a species of the Syngnathidae family. This study provides data on the morphometric, meristic and genetic structuring of the Caspian Sea pipefish, Syngnathus abaster. Eight morphometric characteristics based on total length and five morphometric characteristics based on standard length were analyzed. A total of 50 specimens were collected in bra...
متن کاملStudies on Cytochrome c Oxidase Activity of the Cytochrome ~ 1 ctct 3 Complex from Thermus thermophilus
Cytochrome oxidase from T. thermophilus is isolated as a noncovalent complex of cytochromes c1 and aa3 in which the four redox components of aa3 appear to be associated with a single -55,000-D subunit while the heme C is associated with a -33,000-D peptide (Yoshida, T., Lorence, R. M., Choc, M. G., Tarr, G. E., Findling, K. L., and Fee, J. A. (1983) J. Biol. Chem. 258, 112-123). We have examine...
متن کاملThe Cytochrome C-cytochrome Oxidase Complex
In the preceding paper the oxidation of substrates by “indophenol oxidase” was demonstrated to be a joint action of cytochrome and cytochrome oxidase. It was further shown that with a given amount of oxidase the velocity of hydroquinone oxidation reached a maximum as the amount of added cytochrome was increased. The latter fact immediately suggested the probability that the rapid aerobic oxidat...
متن کاملEvolution of eutherian cytochrome c oxidase subunit II: heterogeneous rates of protein evolution and altered interaction with cytochrome c.
Cytochrome c oxidase subunit II (COII), encoded by the mitochondrial genome, exhibits one of the most heterogeneous rates of amino acid replacement among placental mammals. Moreover, it has been demonstrated that cytochrome c oxidase has undergone a structural change in higher primates which has altered its physical interaction with cytochrome c. We collected a large data set of COII sequences ...
