54Mn2+ as a tracer of the polymerization of actin. Intermediate oligomers condense to give F-actin.
Mg2+, at submicromolar concentrations, is needed for the nucleation of actin [Maruyama (1981) J. Biol. Chem. 256, 1060-1062]. I show here that Mn2+ fulfils the same function. It binds to oligomers present in the ATP-G-actin solutions with a ratio of 2-3 Mn2+ ions per 100 actin monomers and with an a...
