Bacteriophage P4, Psu, polarity suppression protein (IPR010006)

Short name: Phage_P4_Psu

Family relationships



This entry is represented by Bacteriophage P4, Psu, the polarity suppression protein. The characteristics of the protein distribution suggest prophage matches in addition to the phage matches.

This family contains a number of phage polarity suppression proteins (Psu) (approximately 190 residues long). The Psu protein of Bacteriophage P4 causes suppression of transcriptional polarity in Escherichia coli by overcoming Rho termination factor activity [PMID: 9007066].
