Pharma IQ Glossary: Kinase

Kinase, or Phosphotransferase, is a type of enzyme that transfers phosphate groups from high-energy donor molecules, such as adenosine triphosphate (ATP) to specific substrates. The process is referred to as phosphorylation, not to be confused with phosphorolysis, which is carried out by phosphorylases. Phosphorylation is the transfer of a phosphate group to a molecule.
