previous studies indicated that ( i ) t4 gene s product ( gps ) protects infected cells from superinfection lysis from without , ( ii ) the absence of gps in infected cells also leads to lysis from within even when t4 e lysozyme is absent , ( iii ) t4 gene 5 product ( gp5 ) , a polypeptide of the virion baseplate , may be responsible for inducing lysis from without , and ( iv ) altered gp5 of the t4 mutant 5ts1 can replace e lysozyme to cause lysis from within .
