The Effect of Ca super(2+) on the Polymerization of Carp G-Actin

The effect of Ca super(2+) on the G-F transformation of carp G-actin was examined by both the precipitation method and the ultracentrifugation method. 10 mol of Ca super(2+) is necessary for 1 mol G-actin to polymerize to F-actin. This is considered to be the nucleation of F-actin, where the G-actin...

Zusammenfassung:The effect of Ca super(2+) on the G-F transformation of carp G-actin was examined by both the precipitation method and the ultracentrifugation method. 10 mol of Ca super(2+) is necessary for 1 mol G-actin to polymerize to F-actin. This is considered to be the nucleation of F-actin, where the G-actin exists as dimer or trimer. Then, the F-actin nuclei may polymerize to form F-actin molecules.
