Abstract

By means of laser flash photolysis, the transient absorption anisotropy (TAA) of the triplet probe, 5-iodoacetamide-Eosin, labeling rabbit skeletal F-actin was measured in the 10(-6)-10(-3) s time range. The TAA curve at 20 degrees C showed a relatively slow decay phase covering several hundred microseconds and a large residual anisotropy (approximately 0.1 at 2 ms). After analysis with Barkley & Zimm's formula, it was concluded that the TAA of Eosin-F-actin can be approximated by the anisotropy decay due to torsional motion of F-actin.
