The Rex phenotype of altruistic cell death following infection of a lambda lysogen by T4rII mutants is suppressed by plasmids expressing OOP RNA.

Abstract excerpt

The coordinate expression from induced lambda prophages of pLit-rexB-tImm (late immunity transcription, LIT RNA) and po-oop-t(o) (OOP RNA) has remained unexplained. The initial assigned sequence for pLit bore no relationship to po. We have identified two promoter sites for independent rexB transcription, denoted here pLit2 and pLit1, which are separated by about 330 bp. The upstream pLit1 site shares with po a...
