title: Physical characterization of mini-mu and mini-D108.
abstract: Several derivatives of phages Mu and D108 have been isolated that carry an internal deletion generated by one of the IS1 components of a Tn9 transposon located in the A, B, or S gene of the prenatal phage. The deletions remove most of the lytic functions of the phage but leave intact either genes A and B or gene A and the left and the right end of the phages. These deleted derivatives, called mini-Mu and mini-D108, were physically characterized by electron microscopy and digestion with restriction enzymes. Mini-Mu and mini-D108, which carry an antibiotic resistance marker, are described and some of their genetic properties are summarized in the paper by Toussaint et al. (1981).
