Abstract
The ammonium sulfate activation of phosphorylase b has been studied. Ammonium sulfate, when present in high concentrations, induces properties of phosphorylase a in phosphorylase b, such as an enhanced affinity for AMP, a reversal of the glucose-6-P inhibition and enzyme tetramerization. The data are consistent with the interpretation that sulfates bind to the Ser-14 site and the sulfate-protein interactions at this site are responsible for activation of phosphorylase b.
