| ligase | <enzyme, molecular biology> Major class of enzymes that catalyse the linking together of two molecules (category 6 in the I.U.B.C.E. Nomenclature) for example DNA ligases that link two fragments of DNA by forming a phosphodiester bond. (18 Nov 1997) |
|---|---|
| ligase amplification reaction | <molecular biology> Method for detecting small quantities of a target DNA, with utility similar to PCR. It relies on DNA ligase to join adjacent synthetic oligonucleotides after they have bound the target DNA. Their small size means that they are destabilised by single base mismatches and so form a sensitive test for the presence of mutations in the target sequence. (18 Nov 1997) |

| ligase |
In biochemistry, a ligase is an enzyme that can catalyse the joining of two molecules ("ligation" or "gluing together") by forming a new chemical bond, with accompanying hydrolysis of ATP or other similar molecules. For example, an enzyme that catalyzed this reaction would be a ligase: The common names of ligases often include the word "ligase," such as DNA ligase, an enzyme commonly used in molecular biology laboratories to join together DNA fragments. ...
