Summary Circular dichroism (CD) was utilized to probe two discrete loci of the ionophore lasalocid A during conformational perturbations associated with complex formation. This required deconvolution of the observed CD spectrum into components arisin

The ability of ion permeability-inducing agents (ionophores) to complex and transport cations and amines across membranes has provided a novel approach for the pharmacological modification of biological systems. Of particular interest is X-537A, sinc

The divalent ionophores A23187 and X-537A induce parthenogenesis in sea urchin eggs. This results from their ability to mobilize intracellular Ca 2+ , which is implicated in both artificial parthenogenesis as well as the natural fertilization process

Monensin, a carboxylic ionophore, produces strong pressor, positive chronotropic effects and elevates the blood glucose level when injected intravenously (100 μg/kg) into pentobarbital anesthetized dogs or administered orally (2 mg/kg) to conscious

The partition of alkali cations and anions between an aqueous and an immiscible organic phase has been studied in the absence and presence of neutral and carboxylic ionophores of the valinomycin and nigericin types, respectively. Cation extraction in

The turnover numbers of the ionophores valinomycin, the macrolide actins, enniatin B and dicyclohexyl 18-crown-6 for translocation of cations through the mitochondrial membrane have been compared quantitatively. The rank order of decreasing maximum t

Subfractions of adrenal medullary homogenates were analyzed in two-dimensional polyacrylamide gels to assess the extent of protein homology. Chromaffin granule proteins were highly acidic, with the exception of the soluble form of the enzyme dopamine

The significance of intracellular Na+ concentration in catecholamine secretion of cultured bovine adrenal chromaffin cells was investigated using the monovalent carboxylic ionophore monensin. This ionophore, which is known to mediate a one-for-one ex
