Resumen

The molecular recognition of streptomycin by Bacillus subtilis aminoglycoside-6-adenyl transferase has been analysed by a combination of NMR techniques and molecular dynamic simulations. This protein inactivates streptomycin by transferring an adenyl group to position six of the streptidine moiety. Our combined ap-proach provides valuable information about the bioactive conformation for both the antibiotic and ATP and shows that the molecular recognition process for streptomycin involves a conformational selection phenomenon. The binding epitope for both ligands has also been analysed by 1D-STD experiments. Finally, the specificity of the recognition process with respect to the aminoglycoside and to the nucleotide has been studied. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
