Aminoglycoside-modifying enzymes (AMEs) constitute the most prevalent mechanism of resistance to aminoglycosides by bacteria. We show that aminoglycosides can be doubly modified by the sequential actions of AMEs, with the activity of the second AME in most cases unaffected, decreased, or completely abolished. We demonstrate that the bifunctional enzyme AAC(3)-Ib/AAC(6')-Ib' can diacetylate gent...

Ames has used statistical models to generate music in various styles [Ames & Domino 92]. Regardless of the musical results obtained, this approach cannot provide an accurate understanding of the cognitive processes associated to jazz performance. Other approaches (e.g. [Steedman 84]) have been devoted to designing representation frameworks that adopt a systematic logical standpoint. Musical kno...
