Colicin-E9

Gene

col

Organism
Escherichia coli
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

This plasmid-coded bactericidal protein is an endonuclease active on both single- and double-stranded DNA but with undefined specificity.
Colicins are polypeptide toxins produced by and active against E.coli and closely related bacteria.
