ColE1

ColE1 is a plasmid found in bacteria. Its name derives from the fact that it carries a gene for colicin E1 (the cea gene). It also codes for immunity from this product with the imm gene. In addition, the plasmid has a series of mobility (mob) genes. Its size and the presence of a single EcoRI recognition site caused it to be considered as a vector candidate.^[1]
