Restriction endonucleases are named by a standard procedure. The first letter of the enzymes indicates the genus name, followed by the first two letters of the species, then comes the strain of the organism and finally a roman numeral indicating the order of discovery. For example, EcoRI is from Escherichia (E) coli (co), strain RY 13 (R) and first endonuclease (I) to be discovered.
