This process and its inverse, dephosphorylation, are common in biology and could be driven by natural selection. Protein phosphorylation often activates (or deactivates) many enzymes.

WebPhosphorylation often acts as a switch, but its effects vary among proteins. Sometimes, phosphorylation will make a protein more active (for instance, increasing catalysis or letting it bind to a partner). In other cases, phosphorylation may inactivate the protein or cause it to be broken down.
