A calmodulin-activated (Ca(2+)-Mg2+)-ATPase is involved in Ca2+ transport by plasma membrane vesicles from Trypanosoma cruzi.

Abstract

High-affinity Ca(2+)-activated ATPases that do not show any demonstrable dependence on Mg2+ have been reported in the plasma membranes of different trypanosomatids, and it has been suggested [McLaughlin (1985) Mol. Biochem. Parasitol. 15, 189-201; Ghosh, Ray, Sarkar & Bhaduri (1990) J. Biol. Chem. 265, 11345-11351] that these enzymes may have a role in Ca2… (More)
