Abstract
At present, three-dimensional structures characterizing specific tetracycline/protein interactions are available only for the Tet repressor, TetR. This is the regulatory switch for the most common resistance mechanism against tetracyclines, Tc, in Gram-negative bacteria. Crystallographic investigations with at least 2.5 A resolution of TetR/Tc complexes [1 2] and the TetR/DNA complex [3] provide a clear view of endpoints for the functional allosteric pathway of this distinct regulatory system and reveal mechanisms that underlie TetR/Tc recognition and induced conformational changes forcing dissociation of the repressor/operator-DNA complex, TetR/tetO.
