Mg, Ca-activation of ATPase of Paccinian corpuscles

Abstract

An ATPase activated by Mg++ or Ca++ ions was found in single mechanoreceptors (Paccinian corpuscles) of cats; the addition of Ca++ (10−5 M) to the Mg-ATPase increased its activity by 1.6 times. The optimum for activity of Mg- or Ca-ATPase lies in the alkaline pH region. High substrate specificity of Mg,Ca-ATPase was demonstrated. Parachloromercuribenzoate… (More)
