Phosphorylation and Protein Control

Phosphorylation helps control how proteins work in cells. It is the addition or removal of phosphate groups, and it is the most common chemical change that regulates cellular processes. These changes can alter a protein’s structure, activity, stability, location inside the cell, and interactions with other proteins.

Phosphorylation, the addition of a phosphate group, is an important chemical modification that helps cells to regulate protein function.

During phosphorylation, protein kinases transfer the terminal phosphate group of ATP to specific amino acid side chains of a target protein.

As a result, the target protein may change conformation...
