[Discovery of new sites of CA2+ binding by vesiculated fraction of plasma membranes of the smooth muscle cells in the presence of alameticin].
A study carried out with plasma membrane vesicular fraction from rabbit intestine smooth muscle demonstrated that a new type of Ca-binding sites with high affinity appear in a Mg2(+)--free medium. Another type of low affinity Ca-binding sites was revealed in ATP-free medium.
