Vanadate inhibition of the Ca++-ATPase of sarcoplasmic reticulum from pig heart

A Hagenmeyer et al. Basic Res Cardiol. 1980 May-Jun.

Abstract

Ca++-ATPase of sarcoplasmic reticulum from pig heart can be inhibited by vanadate with half maximal inhibition at about 10(-5)M NH4VO3. At the same time vanadate lowers the [Mg++] for maximal activity of the Ca++-ATPase to half, from 8 X 10(-3)M to 4 X 10(-3)M Mg++. At low vanadate concentrations around 5 X 10(-8)M the Ca++-ATPase was activated.
