Superinfection exclusion proteins in mycobacteriophages

What I Found


Superinfection exclusion proteins in mycobacteriophages

  • Group of phages with nearly identical protein closely matching two SIE proteins of enterobacteriophages

  • Surprising. Expected other gram positive phages due to cell wall differences


Superinfection exclusion proteins in mycobacteriophages

  • Compared these to list of SIE proteins known from in vitro experiments.

  • Close match with Imm protein of Coliphage T4
