The phenomenon of glucose catabolite repression was studied in E. coli mutants inable to transport this carbohydrate. The pts 1, H mutant P34 was much less sensitive to the repressive effect of glucose on beta-galactosidase synthesis than the parent type. The 1103 mutant devoid of enzyme 1 of the phosphoenolpyruvate-dependent phosphotransferase system (PTS)(More)
The genome of lambda phage with thermosensitive repressor was integrated into the pts region of the E. coli chromosome. Such a lysogenic culture behaves as a pts mutant at 30 degrees. Heating of cells of this strain leads to the induction of lambda prophage and formation of deletions in the pts region. A mutant with a deletion covering ptsH gene was(More)
