A colleague has just identified a novel protein kinase that acts to phosphorylate and inactivate a protein X that you have begun to study. From your understanding of the regulation of protein activity, what additional protein do you predict will interact with the phosphorylated form of protein X to restore it’s activity?

Solution

The additional protein that will interact with the phosphorylated form of protein X to restore its activity is dephosphorylase enzyme which will remove the phosphate group attached by the protein kinase enzyme.
