First letter of the name comes from the genus and the second two letters come from species of the prokaryotic cell from which they were isolated.
For example, EcoR I comes from
Eco= Escherichia coli RY 13
In EcoR I,
letter R= derived fron the name of the strain,
Roman numbers indicate the order in which the enzymes were isolated from that strain of bacteria.
