title: Characterization of B278, a phage different from Mu that also produces auxotrophic mutations in Escherichia coli K12.
abstract: Bacteriophage B278 has been characterized and compared with Mu, the only phage known to produce random mutations in E. coli. Although both phages are morphologically indistinguishable and have a similar host range, they clearly differ at both the protein and the DNA level. B278 apparently possesses a DNA protection mechanism that is different from the mom system described for Mu.
