Abstract
The presence of alpha-actinin has little influence on polymerizing act in with regards to the lag phase, rate and amplitude. Rising KCl or Mg Cl2 concentrations parallel an increase in polymerization rate and a d ecrease in lag phase for both protein species. The observed overall sm aller actin fluorescence amplitudes in the presence of alpha-actinin i s due to a higher ratio of free G-actin to F-actin at steady state.
