Summary The partially circularly permuted, terminally redundant structure of the DNA of phage ϕH has been confirmed by a cleavage map for the restriction enzymes PstI, ClaI, BglII, HindIII, and, partially, BamHI. Six variants of phage ϕH have been isolated from 71 single plaques. Their genomes differ by several insertions, a deletion, and an inversion of a DNA segment with a minimal length of 11 kb. The inversion occurs with high frequency in variants carrying at the flanks of the invertible DNA in verted repeats of a 1.8 kb DNA element which shares sequence homology with the DNA of H. halobium and may be involved in the extreme variability of its genome.
