In vivo and in vitro evidence for an anti-Rho activity induced by the phage P4 polarity suppressor protein Psu.

Virology - 6 Jan 1997

Linderoth N A, Tang G, Calendar R

Abstract excerpt

The polarity suppression (Psu) protein of bacteriophage P4 causes suppression of transcriptional polarity in Escherichia coli by overcoming Rho termination factor activity. Two new psu mutants defective in polarity suppression are described. The psu5 mutation deletes codons 95-98 from about the m...
