Abstract

In the present technical note for 31P-NMR, we used a new pH-dependent dissociation constant of MgATP, and re-estimated changes in the intracellular free Mg2+ concentration and pH from the chemical shifts of beta- and gamma-ATP during Na+-removal in smooth muscle. We confirmed the role of Na+ - Mg2+ exchange.
