Abstract

The association of dimetric rabbit phosphorylase b to tetrameric form was studied. The results indicate that transformation from dimer to tetramer in the presence of 0.2 M sodium fluoride and 0.04 M 2-mercapto-ethanol (at 20° at pH 6.8 or 7.5) is influenced by 5′-AMP as follows: 1. (1){A figure is presented} 2. (2){A figure is presented}. In the absence of sodium fluoride, complete tetramerization of the enzyme with 5 × 10^-3 M AMP was not possible.
