[The effect of specific mutation crp a in the genetic locus of receptor protein cAMP (CRP) on the expression of Escherichia coli K-12 deo-operon].

Genetika - 1 Mar 1990

Nechaeva G D, Mironov A S

Abstract excerpt

Expression of the deo operon of Escherichia coli is subjected to double negative control by DeoR and CytR repressors and to the positive control by cAMP-CRP complex. However, sensitivity of the deo operon to catabolite repression is only revealed in bacteria with disrupted synthesis of the CytR protein, since the function of the latter is to prevent CRP activation of the deo operon transcription. In the present...
