    • 52 (lac HP62-V52C). The V52C mutation was designed so as to link two lac headpieces by means of a disulfide bond, and biochemical experiments showed DNA binding parameters of the dimeric headpiece comparable with those of the intact repressor (12).

    • The NOD sequence (5′-CGATAAGATATCTTATCG-3′) was designed so as to be entirely different in all positions from the naturally occurring operators. Its binding affinity for the lac headpiece is at nonspecific levels as determined by isothermal titration calorimetry. Special care has been taken so that the length of the DNA fragment matches exactly the DNA binding site of lac repressor. Longer sequences have been tested, but they result in substantial heterogeneity originating primarily from protein sliding along the DNA.

    • 56 occurs. Furthermore, the chemical shifts of the central base pairs are identical in the free and bound NOD fragment, consistent with the absence of any structural distortion of the DNA in the nonspecific complex.
