  • Title: Interactions between cro repressor and the model specific binding site.
    Author: Kirpichnikov MP, Kurochkin AV, Chernov BK, Skryabin KG.
    Journal: FEBS Lett; 1984 Oct 01; 175(2):317-20. PubMed ID: 6236998.
    Abstract:
    Binding of lambda phage cro repressor to the synthetic half of OR3, the most conservative half of the specific binding sites, was investigated by proton nuclear magnetic resonance spectroscopy. It was found that the alpha-helical segment (27-36) of the protein was involved in specific interactions with the model binding site. The 3-dimensional structure of cro repressor does not change noticeably upon complex formation. Intercalation can be excluded as a possible means of interaction.
