  • PubMed Abstract: 

    The TipAL protein, a bacterial transcriptional regulator of the MerR family, is activated by numerous cyclic thiopeptide antibiotics. Its C-terminal drug-binding domain, TipAS, defines a subfamily of broadly distributed bacterial proteins including Mta, a central regulator of multidrug resistance in Bacillus subtilis. The structure of apo TipAS, solved by solution NMR [Brookhaven Protein Data Bank entry 1NY9], is composed of a globin-like alpha-helical fold with a deep surface cleft and an unfolded N-terminal region. Antibiotics bind within the cleft at a position that is close to the corresponding heme pocket in myo- and hemoglobin, and induce folding of the N-terminus. Thus the classical globin fold is well adapted not only for accommodating its canonical cofactors, heme and other tetrapyrroles, but also for the recognition of a variety of antibiotics where ligand binding leads to transcriptional activation and drug resistance.
