Abstract

The effect of phalloidin on filaments polymerized from ADP-actin monomers of the heart muscle was investigated with differential scanning calorimetry. Heart muscle contains alpha-skeletal and alpha-cardiac actin isoforms. In the absence of phalloidin the melting temperature was 55 degrees C for the alpha-cardiac actin isoform and 58 degrees C for the alpha-skeletal one when the filaments were generated from ADP-actin monomers. After the binding of phalloidin the melting temperature was isoform independent (85.5 degrees C). We concluded that phalloidin stabilized the actin filaments of alpha-skeletal and alpha-cardiac actin isoforms to the same extent when they were polymerized from ADP-actin monomers.
