[The possible H+-dependent functional connection between cell membrane and mitochondria in smooth muscle cells].
It has been found that Mg2, ATPase of the smooth muscle cells plasma membrane has the properties of an H(+)-sensitive enzymatic sensor which is characterized by a linear dependence between the initial maximal rate of the reaction, V0, and the pH value. The feasible role of plasma membrane Mg(2+)-ATPase in some reactions responsible for the control of proton and Ca2+ homeostasis in myometrium cells has been debated.
