From Wikipedia

In biochemistry, a kinase (, EC 2.7.-.-) is a protein enzyme that catalyzes the transfer of phosphate groups to substrates. This process is known as phosphorylation. Typically ATP is the phosphate donor. Kinases are pervasive, the human genome codes for about 500 of these enzymes. Kinases are part of the larger family of phosphotransferases. Kinases should not be confused with phosphorylases, which catalyze the addition of inorganic phosphate groups to an acceptor, nor with phosphatases, which remove phosphate groups (dephosphorylation). The phosphorylation state of a molecule, whether it be a protein, lipid or carbohydrate, can affect its activity, reactivity and its ability to bind other molecules. Therefore, kinases are critical in metabolism, cell signalling, protein regulation, cellular transport, secretory processes and many other cellular pathways, which makes them very important to physiology.
