EC Number Crystallization (Comment) Organism
2.3.1.82 structure of the kanamycin A complex of AAC(6')-Im. The substrate binds in a shallow positively-charged pocket, with the N6' amino group positioned appropriately for an efficient nucleophilic attack on an acetyl-CoA cofactor. Comparison of fortimicin binding to AAC(6')-Im and AAC(6')-Ie Escherichia coli

General Information

EC Number General Information Comment Organism
2.3.1.82 physiological function when expressed in the Escherichia coli JM83 strain, AAC(6')-Im produces resistance to a wide range of clinically important 4,6-disubstituted aminoglycosides with minimal inhibitory concentration values 8-128fold above those for the recipient strain Escherichia coli
