Phosphorylation

Phosphorylation is the addition of a phosphate (PO43-) group to a protein or other organic molecule. Phosphorylation activates or deactivates many protein enzymes.

Protein phosphorylation in particular plays a significant role in a wide range of cellular processes. Its prominent role in biochemistry is the subject of a very large body of research (as of March 2009, the Medline database returns nearly 160,000 articles on the subject, largely on protein phosphorylation).
