title: Over-expression of rexA nullifies T4rII exclusion in Escherichia coli K(lambda) lysogens.
abstract: Dosage and relative cellular levels of RexA and RexB proteins encoded by the rexA-rexB genes of a lambda prophage are important for the Rex+ phenotype, which was nullified when greater RexA or RexB was provided than was necessary for the complementation of a rexA- or a rexB- prophage.
