Modulation of phage Mu repressor DNA binding and degradation by distinct determinants in its C-terminal domain.

Abstract excerpt

Rapid degradation of the bacteriophage Mu immunity repressor can be induced in trans by mutant, protease-hypersensitive repressors (Vir) with an altered C-terminal domain (CTD). Genetic and biochemical analysis established that distinct yet overlapping determinants in the wild-type repressor CTD modulate Vir-induced degradation by Escherichia coli ClpXP protease and DNA binding by the N-terminal DNA-binding...
