The interaction of ribonuclease inhibitor (RI) with kanamycin was studied by molecular modeling. The preliminary binding model was constructed using the Affinity module of the Insight II molecular modeling program and the key residues involved in the combination of RI binding to kanamycin were determined. Meanwhile, we determined relevant surface characteristics determining the interaction behavior. The modeling results indicated that electrostatic interactions and H-bond forces may work as major factors for the molecular interaction between kanamycin and RI. The above results are useful for elucidating the molecular principles upon which the selectivity of a kanamycin is based. The quartz-crystal microbalance (QCM) is a new method usually used to monitor the binding function of macromolecules with samples online in a flow-injection analysis (FIA) system. The experimental results demonstrate that kanamycin has an extraordinary affinity to the basic protein RI, and our result is consistent with the molecular modeling results. These principles can in turn be used to study the molecular recognition mechanism and design a mimic of kanamycin for the development of new RI binders.
