Unreferenced date August 2007 In biochemistry , a synthase is an enzyme that catalyse s a Biosynthesis synthesis process. Following the EC number classification, they belong to the group of ligase s, with lyase s catalysing the reverse reaction. 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 with any enzyme that catalyzes synthesis whether or not it uses nucleoside triphosphates , whereas synthetase is to be used synonymously with ligase . ref http www.chem.qmul.ac.uk iubmb newsletter misc synthase.html ref Examples ATPsynthase Citrate synthase Tryptophan synthase Pseudouridine synthase Fatty acid synthase Cellulose synthase UDP forming Cellulose synthase GDP forming References references Enzymes Category Lyases Enzyme stub de Synthasen fr Synthase lt Sintaz pl Syntazy sv Syntas zh ... more details
