The YjbH protein of Bacillus subtilis enhances ClpXP-catalyzed proteolysis of Spx.

abstract：:Plasmid pE194 has been shown to be rescued by integration after cultivation of infected Bacillus subtilis recE4 cells at a restrictive high temperature. The plasmid is also spontaneously excised from the chromosome at a low frequency by precise or imprecise excision (J. Hofemeister, M. Israeli-Reches, and D. Dubnau, M...
