synthetase(redirected from aminoacyl-tRNA s's)
Also found in: Dictionary, Encyclopedia.
ligase; any of a class of enzymes that catalyze the joining together of two molecules coupled with the breakdown of a pyrophosphate bond in ATP or a similar triphosphate.
An enzyme catalyzing the synthesis of a specific substance. Synthetase is limited, in the Enzyme Commission Report, to use as a trivial name for the ligases (EC class 6), which in turn are those synthesizing enzymes that require the cleavage of a pyrophosphate linkage in ATP or a similar compound. Reversal of lyase (EC class 4) reactions, producing a synthesis, is indicated (in trivial names) by synthase; such reactions do not involve pyrophosphate cleavage. For individual synthetases, see the specific names.
Any of a group of enzymes that catalyze the synthesis of a compound. Also called synthase.
An enzyme catalyzing the synthesis of a specific substance.
