Protoplast formation and leakage of intramembrane cell components: induction by the competence activator substance of pneumococci.

abstract：:Tyrosine-mediated repression of aroF and tyrP was studied by inserting DNA sequences between the two adjacent TYR R boxes which, in each case, overlap the respective RNA polymerase binding sites of these genes. In both cases, repression was greatest when homologous regions of these two TYR R boxes were on the same fac...
