A segment of the phage HK022 chromosome is a mosaic of other lambdoid chromosomes.
We report the sequence of a region of the PR operon of lambdoid phage HK022 and an analysis of the proteins it encodes. This region has DNA sequence elements and open reading frames that resemble those found in phages lambda, P22, and phi 80. The open reading frames encode homologs of the lambda CII transcription activator, the P22 DNA replication proteins, and a fourth protein of unknown function.
