What is the meaning of synthetase?
What is the meaning of synthetase?
Definition of synthetase : 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 ligase.
What does it mean when an enzyme has the name synthase?
catalyzes the synthesis
Synthase is an enzyme that catalyzes the synthesis of new compounds in the body. However, the Joint Commission on Biochemical Nomenclature updated the definition, describing a synthase as any enzyme that catalyzes synthesis, regardless of energy source.
What class of enzyme is synthase?
lyase group
Nevertheless, synthases belong to the lyase group (EC 4). Lyases are enzymes that catalyze the breaking a chemical bond between two parts of a molecule through biochemical means other than hydrolysis and oxidation. Accordingly, synthases are lyases going in the reverse direction and are NTP-independent.
What is the function of a synthetase?
Aminoacyl-tRNA synthetases (AARSs) are the enzymes that catalyze the aminoacylation reaction by covalently linking an amino acid to its cognate tRNA in the first step of protein translation.
Are kinases transferases?
Groups that are classified as phosphate acceptors include: alcohols, carboxy groups, nitrogenous groups, and phosphate groups. Further constituents of this subclass of transferases are various kinases. A prominent kinase is cyclin-dependent kinase (or CDK), which comprises a sub-family of protein kinases.
Is synthetase a ligase?
ligase, also called Synthetase, any one of a class of about 50 enzymes that catalyze reactions involving the conservation of chemical energy and provide a couple between energy-demanding synthetic processes and energy-yielding breakdown reactions.
What type of enzyme is synthetase?
Synthases are enzymes that promote the synthesis of a compound or substance. Their action is the opposite of that of snythetases. Furthermore, synthases do not use or require a high-energy source (e.g. ATP) whereas synthetases do. Nevertheless, synthases belong to the lyase group (EC 4).

What does tRNA synthetase mean?
Also called tRNA synthetase. a ligase that assists in translating the genetic code into protein by linking a transfer RNA with a specific amino acid. Random House Kernerman Webster’s College Dictionary, © 2010 K Dictionaries Ltd. Copyright 2005, 1997, 1991 by Random House, Inc. All rights reserved.
How many glutamine synthetase genes are there in barley?
Two glutamine synthetase genes, HvGS1_1 (gb| X69087.1) which encodes cytoplasmic glutamine synthetase [10, 28] and HvGS2 (gb| X53580.1) which encodes chloroplastic glutamine synthetase [14, 28], were included in the study and analyzed in the shoots and roots in the barley cultivars.
