Interaction of carbonyl cyanide 3-chlorophenylhydrazone with cytochrome c oxidase.
Cytochrome c oxidase binds protonophore carbonyl cyanide 3-chlorophenylhydrazone (CCCP) with high affinity. There are 1.46 high-affinity binding sites per cytochrome c oxidase for CCCP with dissociation constant 2.7 x 10(-7) mol/l. The bond between the CCCP and cytochrome c oxidase accomplishes through the group on cytochrome c oxidase with pKa 6.64 and is based on the electrostatic interaction...
متن کاملActivation of Myosin Adenosine Triphosphatase by Carbonyl Cyanide P-chlorophenylhydrazone.
In an accompanying paper (l), it is shown that y-(p-arsenosophenyl)-n-butyrate activates the adenosine triphosphatase of both myosin and mitochondria, and several analogies between the properties of the active sites of these two energy transduction enzymes are discussed. Carbonyl cyanide p-chlorophenylhydrazone, which uncouples osidative phosphorylation at concentrations as low as lop7 &r (a), ...
متن کاملMaternal aging affects oocyte resilience to carbonyl cyanide-m-chlorophenylhydrazone -induced mitochondrial dysfunction in cows
Mitochondrial quality control is important for maintaining cellular and oocyte viability. In addition, aging affects mitochondrial quality in many cell types. In the present study, we examined how aging affects oocyte mitochondrial biogenesis and degeneration in response to induced mitochondrial dysfunction. Cumulus oocyte complexes were harvested from the ovaries of young (21‒45 months) and ag...
متن کاملMechanism of inhibition by carbonyl cyanide m-chlorophenylhydrazone and sodium deoxycholate of cytochrome P-450-catalysed hepatic microsomal drug metabolism.
1. Treatment of liver microsomal fraction with 0.03-0.12% sodium deoxycholate and 0.005-0.06 mM carbonyl cyanide m-chlorophenylhydrazone decreases phospholipid-dependent hydrophobicity of the microsomal membrane, assayed by the kinetics of 8-anilinonaphthalene-1-sulphonate binding and ethyl isocyanide difference spectra. 2. Sodium deoxycholate at a concentration of 0.01% lacks its detergent pro...
متن کاملThe alteration of mitotic events by ionophore A23187 and carbonyl cyanide n-chlorophenylhydrazone.
A large quantity of published work indicates that calcium ions may be involved in the regulation of mitotic events and recent reports suggest that the onset of chromosome movement is dependent upon a transient increase in free cytosolic calcium ions. In this paper we examine the effects of two agents known to perturb intracellular calcium pools on mitosis in HeLa cells. These were the calcium-s...
