Crystal structure and specific binding mode of sisomicin to the bacterial ribosomal decoding site.
Acs Med.Chem.Lett., 3:741-744, 2012

PubMed Abstract: Sisomicin with an unsaturated sugar ring I displays better antibacterial activity than other structurally related aminoglycosides, such as gentamicin, tobramycin, and amikacin. In the present study, we have confirmed by X-ray analyses that the binding mode of sisomicin is basically similar but not identical to that of the related compounds having saturated ring I. A remarkable difference is found in the stacking interaction between ring I and G1491. While the typical saturated ring I with a chair conformation stacks on G1491 through CH/π interactions, the unsaturated ring I of sisomicin with a partially planar conformation can share its π-electron density with G1491 and fits well within the A-site helix.
