[Effect of temperature on formation of lysozyme in E. coli CRT 266 (dnaB ts) after infection with bacteriophage T3].

Lysozyme formation induced by bacteriophage T3 was studied in the ts-mutant E. coli CRT 266 (dnaBts) and in the wild-type E. coli CR 34--45 (dnaB+) at different temperatures. It was found that lysozyme was formed in E. coli CRT 266, however, no lysozyme synthesis took place at 41.5 degrees C. These results indicate that the expression of the lysozyme gene is disturbed in the ts-mutant at 41.5 degrees C.
