title: Temperate coliphage HK253: attachment site and restricted transduction of proAB mutants of Escherichia coli K-12.
abstract: Temperate coliphage HK253 integrates near the proAB locus on the Escherichia coli K-12 chromosome. It can bring about specialized transduction of proAB and phoE mutants of E. coli, but it is incapable of general transduction. One of the proline-transducing particles was found to be nondefective.
