[Effect of mutation crp11 in the 3',5'-cyclic adenosine monophosphate receptor on the expression of the udp gene in Escherichia coli K12 strains deficient for transcription termination factors (rho ts15)].

The suppression of temperature sensitive phenotype caused by mutation rho ts 15, making cells deficient in transcription termination, but mutation crp11 impairing the cAMP-receptor protein (cap) restores transcription termination on IS3 sequence in galactose operon and on the site before the promoter of udp gene in strains crp11 rho ts15. The obtained data suggest the direct interaction between factor Rho and cAMP-CAP complex in transcription process.
