brief introduction
Synthase: will accompany Adenosine triphosphate （ ATP ）The enzyme that catalyzes the synthesis reaction by decomposing is called synthase. In this process, ATP is decomposed into ADP and orthophosphoric acid or AMP and pyrophosphoric acid. The catalytic reaction mechanism is as follows: A + B + ATP ←→ A · B+ADP+Pi or
A + B + ATP ←→ A · B + AMP + PPi
For example, Aminoacyl tRNA synthetase It belongs to this kind of enzyme.
