Spiegazione:
La fosforilazione is an important mechanism by which the activity of proteine can be altered after they are formed. A phosphate group (#PO""_4^(3-)#) is added to a protein by specific enzymes called kinases. This phosphate group is usually provided by ATP, the energy carrier of the cell.
