The product of the bacteriophage S gene has been previously shown to be required for an essential step in triggering host cell lysis. By using two different protein labeling systems, maxicells and UV-irradiated infected cells, we identified the S gene product as an 8,500-molecular-weight polypeptide associated with the cell envelope. The apparent molecular weight is significantly less than the 11,500 predicted from the S gene sequence. We were unable to confirm two previous identifications of S gene products, an acidic 15,000-molecular-weight polypeptide found by two-dimensional gel electrophoresis of infected cells and a 5,500-molecular-weight polypeptide in purified phage particles.
