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).

For more information about Phosphorylation, read the full article at Wikipedia.
