A role for accessory genes rI.-1 and rI.1 in the regulation of lysis inhibition by bacteriophage T4.

Lysis inhibition (LIN) is a known feature of the T-even family of bacteriophages. Despite its historical role in the development of modern molecular genetics, many aspects of this phenomenon remain mostly unexplained. The key element of LIN is an interaction between two phage-encoded proteins, the T holin and the RI antiholin.
