Abstract excerpt
We have isolated 21 mutants of catabolite gene activator protein (CAP) defective in transcription activation at the lac promoter but not defective in DNA binding. The amino acid substitutions in the mutants map to a single region of CAP: amino acids 156-162. As assessed in vitro, the substituted CAP variants are nearly completely unable to activate transcription at the lac promoter but bind to DNA with the same...
