In biochemistry, a synthase is an enzyme that catalyses a synthesis process. Note that, originally, biochemical nomenclature distinguished synthetases and synthases. Under the original definition, synthases do not use energy from nucleoside triphosphates (such as ATP, GTP, CTP, TTP, and UTP), whereas synthetases do use nucleoside triphosphates. However, the Joint Commission on Biochemical Nomenclature (JCBN) dictates that 'synthase' can be used wit… Websynthetase: [noun] an enzyme that catalyzes the linking together of two molecules usually using the energy derived from the concurrent splitting off of a pyrophosphate group from a triphosphate (such as ATP) — called also#R##N# ligase.
