title: Location of the abi, col and imm genes on pHU011, a colicin Ib plasmid derivative.
abstract: A cleavage site map of pHU011, a derivative of the colicin Ib plasmid containing the complete SalI-B fragment ligated to pBR322, has been determined. Sites of cleavage by PstI were determined using the Smith and Birnstiel [Nucl. Acids Res. 3 (1976) 2387-2398] method of mapping, whereas those for XbaI, XhoI, and HindIII were determined by double digestions or digestion of isolated fragments. In addition, the sites of the abi gene, which causes the abortive infection by T5 bacteriophage, and of the colicin (col) gene have been determined. The results indicate that these genes are not contiguous.
