thumb|300px|Eco RII dimer based on [[Protein Data Bank|PDB ID 1NA6 ]] EcoRII (pronounced 'eco R two') is an Restriction endonuclease enzyme (REase) of the restriction modification system (RM) naturally found in Escherichia coli, a Gram-negative bacteria. Its molecular mass is 45.2 kDa, being composed of 402 amino acids.
==Mode of action== EcoRII is a bacterial Type IIE REase that interacts with two or three copies of the pseudopalindromic DNA recognition sequence 5'-CCWGG-3' (W = A or T), one being the actual target of cleavage, the other(s) serving as the allosteric activator(s). EcoRII cuts the target DNA sequence CCWGG, generating sticky ends.
