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 کاملSynergistic efficacy of Bisbenzimidazole and Carbonyl Cyanide 3-Chlorophenylhydrazone combination against MDR bacterial strains
Activation of efflux systems and the formation of biofilm are majorly adapted by microbes to resist antimicrobial agents. PPEF (bisbenzimidazole) targeting topoisomerase IA is observed to be an effective bactericidal agent against both Gram-positive and Gram-negative bacterial strains and thus can be developed as potent broad-spectrum antibiotic against MDR strains. PPEF treatment did not cause...
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 کاملMutants of Mycobacterium smegmatis unable to grow at acidic pH in the presence of the protonophore carbonyl cyanide m-chlorophenylhydrazone.
Mycobacterium smegmatis is able to grow and survive at acidic pH, and exhibits intracellular pH homeostasis under these conditions. In this study, the authors have identified low proton permeability of the cytoplasmic membrane, and high cytoplasmic buffering capacity, as determinants of intrinsic acid resistance of M. smegmatis. To identify genes encoding proteins involved in protecting cells f...
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...
