  • Title: [Isolation and characterization of Pseudomonas aeruginosa bacteriophage phikF77 mutants].
    Author: Kulakov LA, Balakshina VV, Morenkova MA, Zhulanova EIu, Boronin AM.
    Journal: Genetika; 1991 Nov; 27(11):1904-11. PubMed ID: 1802782.
    Abstract:
    It was found that phage phi kF77 is resistant to all known Pseudomonas aeruginosa restriction systems. Three types of mutants (dc-) which were unable to grow on different restrictive strains were isolated. All of them belong to one complementation group. Some of these mutations affected also the number of nicks in phage phi kF77 DNA and increased phage resistance to temperature treatment. It may be supposed that genes responsible for antirestriction mechanisms and introduction of nicks into DNA are connected in definite way.
