Figure 1. Comparison of the overall protein part of LacI
tetramer structures from an identical viewpoint with respect to
monomer A (green). The dimer-dimer interface and distances
between monomers vary strongly due to the rotation of the
CD-dimer. (a) our model, (b) IPTG and ethyl mercury-bound (PDB
code 1TLF), (c) apoform (1LBI), (d) IPTG-bound (1LBH) and (e)
DNA-bound (1LBG). The distances between the C -atoms
of B102 and D102 (in ångströms) are indicated.
