Ligases

Ligases are enzymes that join two molecules together by catalysing the synthesis of a new chemical bond between the molecules.^[1] Ligases require energy, generally in the form of nucleoside triphosphates, in order to carry out their function.

Ligase enzymes often have the words 'ligase' or 'synthetase' in their name, for example, 'DNA ligase'. ^[2]
