Type I restriction enzymes cut DNA at random locations far from their recognition sequence, type II cut within or close to their recognition sequence, type III cut outside of their recognition ...

Type III restriction–modification (R–M) systems are composed of two enzymes: a methyltransferase (encoded by a mod gene) and a restriction endonuclease (encoded by a res gene).

Market Segmentation: Segmentation By Type Based on types, the global restriction enzyme market is segmented into type I, type II, type III, and others.
