Question

what is phosphorylation??

Answer 1

Phosphorylation is an important mechanism by which the activity of proteins can be altered after they are formed. A phosphate group (PO3−4) is added to a protein by specific enzymes called kinases. This phosphate group is usually provided by ATP, the energy carrier of the cell.

Answer 2

In chemistry, phosphorylation of a molecule is the attachment of a phosphoryl group. Together with its counterpart, dephosphorylation, it is critical for many cellular processes in biology.
