Colicin is a protein produced by bacteria with Col plasmids. Its function is to attack E. coli through actions on its inner membrane ion channels or through ribonuclease or deoxyribonuclease actions. The C terminal domain is the ribonuclease domain. It specifically cleaves tRNA anticodons which recognise codons in the form NAY (N:any nucleotide, A:adenosine, Y:pyrimidine) which corresponds to Tyrosine, Histidine, Asparagine and Aspartic Acid. E5-CRD can be referred to as an RNA restriction enzyme that specifically recognizes and cleaves single-stranded GU sequences. [1]
