	''Eco''RI is a type II restriction endonuclease. It recognizes and cleaves DNA on a specific palindromic sequence: GAATTC. ''Eco''RI has been extracted from strain R Escherichia coli, a common bacterium, which populates the intestine of mammalians. In bacteria, restriction enzymes protect the cell by cutting foreign DNA from bacteriophages (specific bacterial viruses) in both strands. Bacterial DNA is protected by a specific methylation of ''Eco''RI recognition sequences.		''Eco''RI is a type II restriction endonuclease.
