8055911-3	1994	Phalloidin, subfragment 1 isolated from rabbit skeletal muscle myosin and chicken intestinal myosin I are demonstrated to be able to polymerize the actin from this complex in the presence of 1 mM MgCl2.	Magnesium Chloride	196-201	actin, beta	Gallus gallus	148-153	
8055911-11	1994	This Kd was found to be 0.4 microM in the presence of 1 mM MgCl2 and the absence of KCl and, thus, close to the critical concentration of actin polymerization under these conditions.	Magnesium Chloride	59-64	actin, beta	Gallus gallus	138-143	
8395885-3	1993	At pH 7.5 and 37 degrees C, in the presence of 0.1 M KCl and 2 mM MgCl2, the dissociation constant at infinite actin dilution, Ko, is 2.17 microM.	Magnesium Chloride	66-71	actin, beta	Gallus gallus	111-116
