title: [Effect of gradients of monovalent cations on active transport of Ca2+ in the sarcoplasmic reticulum and proteoliposomes].
abstract: Artificially generated K+ gradient from the sarcoplasmic reticulum vesicles enhances the ATP-dependent Ca2+ transport. The effect is not specific for K+, and is observed when K+ is replaced by Na+ or choline. Dissipation of the K+, Na+, choline gradient does not influence the ATP-dependent Ca2+ transport in proteoliposomes from asolectin and purified Ca2+-ATPase. The K gradient in the presence of valinomycin stimulates the ATP-dependent Ca2+ transport in proteoliposomes.
