synthetase

 [sin´thĕ-tās]
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.

syn·the·tase

(sin'thĕ-tās),
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.

synthetase

/syn·the·tase/ (-thĕ-tās) a term used in the names of some of the ligases, no longer favored because of its similarity to synthase and its emphasis on reaction products.

synthetase

(sĭn′thĭ-tās′, -tāz′)
n.
Any of a group of enzymes that catalyze the synthesis of a compound. Also called synthase.

syn·the·tase
