The uptake and binding of the lipophilic cations ethidium+, tetraphenylphosphonium+ (TPP+), triphenylmethylphosphonium+ (TPMP+), and tetraphenylarsonium+ (TPA+) in rat liver mitochondria and submitochondrial particles were investigated. The effects of membrane potential, surface potentials and cation concentration on the uptake and binding

We studied the relationship between surface charge and release of Ca2+ in the heavy sarcoplasmic reticulum (SR) of skeletal muscle. The inner and outer surface potentials and charge densities of the membrane treated with a lipophilic anion, tetraphenylboron (TPB-), were

V Shoshan et al.
The Journal of biological chemistry, 258(5), 2837-2842 (1983-03-10)
The lipophilic anion tetraphenylboron (TPB-) but not the lipophilic cation tetraphenylarsonium (TPA+) inhibited ATP-dependent Ca2+ accumulation by isolated sarcoplasmic reticulum. TPB- did not inhibit ATP hydrolysis but did induce Ca2+ release from preloaded vesicles. It did not appear to disrupt
A Zaritsky et al.
Journal of bacteriology, 147(3), 1054-1062 (1981-09-01)
Lipophilic cations (tetraphenylarsonium, tetraphenylphosphonium, and triphenylmethylphosphonium) caused a number of major changes in the physiology of Bacillus subtilis. Macromolecular synthesis was inhibited, adenosine 5'-triphosphate concentration increased, swimming speed was reduced, tumbling was suppressed, and the capacity to take up the
