The polarity suppression factor of bacteriophage P4 is also a decoration protein of the P4 capsid.

Virology - 1 Jun 1992

Isaksen M L, Rishovd S T, Calendar R, Lindqvist B H

Abstract excerpt

We show that the product of the polarity suppression (psu) gene from bacteriophage P4 associates with P4 capsids. This association can occur when Psu is (i) provided in vivo from the P4 genome or from a plasmid or (ii) provided in vitro by mixing viable phage particles with Psu protein. Psu is unable to associate with the larger capsid of P4's helper phage P2. Discrimination of the P4 and P2 capsids by Psu...
