[gamma-32P]ATP as a tracer of the fragmentation of Ca-F-actin.
[gamma-32P]ATP-G-actin was polymerized in 4 mM-CaCl2, and the distribution of the radioactive nucleotide among the oligomeric and the polymeric species was studied. The results obtained are best explained by assuming spontaneous fragmentation.
