WebJun 1, 2011 · The γ and ϵ subunits of F0F1-ATP synthase from photosynthetic organisms display unique properties not found in other organisms. Although the γ subunit of both chloroplast and cyanobacterial F0F1 contains an extra amino acid segment whose deletion results in a high ATP hydrolysis activity (Sunamura, E., Konno, H., Imashimizu … WebUnlike FOF1, ATPase activity of the isolated F1 was not affected by DCCD at pH values of >7.5. (data not shown). Therefore, high sensitivity to DCCD inhibition is a good indication of the intactness of our FOF1 preparation. The reconstituted vesicles containing purified FOF1 showed substantial ATP-driven proton-pumping activity,

WebApr 25, 1984 · The FoF1-ATPasel then catalyzes the conversion of this proton electrochemical potential energy into the terminal bond energy of ATP. Two factors contribute to the proton electrochemical potential (ApH+) across the membrane, the diffusion potential of protons, or the ApH, and the electrical potential (A+). How the FoFl-ATPase … WebMar 13, 2015 · We showed previously that active PKC-α maintains F0F1-ATPase activity, whereas inactive PKC-α mutant (dnPKC-α) blocks recovery of F0F1-ATPase activity after injury in renal proximal tubules (RPTC). This study tested whether mitochondrial PKC-α interacts with and phosphorylates F0F1-ATPase.

WebUsing a library of genomic DNA from Desulfovibrio vulgaris Miyazaki F, a strict anaerobe, and two synthetic deoxyoligonucleotide probes designed for F-type ATPases, the genes for open reading frames (ORFs) 1 to 5 were cloned and sequenced. The WebF 1 is composed of 5 polypeptide units α3β3γδε that bind to the surface of the F o domain. [1] F-ATPases usually work as ATP synthases instead of ATPases in cellular environments. That is to say, it usually makes ATP from the proton gradient instead of working in the other direction like V-ATPases typically do.
