Molecular dynamics characterization of the structures and induction mechanisms of a reverse phenotype of the tetracycline receptor.

Abstract excerpt

Molecular-dynamics simulations have been used to investigate the mechanism of induction of a mutant (revTetR) of the tetracycline repressor protein (TetR) that shows the reverse phenotype (i.e., it is induced in the absence of tetracyclines and not in their presence). Low-frequency, normal-mode analyses demonstrate that the reverse phenotype is reproduced by the simulations on the basis of criteria established...
