Kinases are enzymes that catalyze the transfer of phosphate groups from phosphate-donating molecules to substrates. This process is known as phosphorylation, where the substrate gains a phosphate group and the donating molecule loses a phosphate group.  Substrate acceptors may be small organic molecules such as glucose or macromolecules such as proteins, and the phosphorylated acceptor molecule may be more or less active than the non-phosphorylated form.  Kinases are widely involved in signal transduction pathways and control complex cellular functions.
