| - | Amikacin is the 4,6-linked aminoglycoside modified at position N1 of the, 2-deoxystreptamine ring (ring II) by the L-haba group. In the present, study, the crystal structure of a complex between oligonucleotide, containing the bacterial ribosomal A site and amikacin has been solved at, 2.7 A resolution. Amikacin specifically binds to the A site in practically, the same way as its parent compound kanamycin. In addition, the L-haba, group interacts with the upper side of the A site through two direct, contacts, O2*...H-N4(C1496) and N4*-H...O6(G1497). The present crystal, structure shows how the introduction of the L-haba group on ring II of, aminoglycoside is an effective mutation for obtaining a higher affinity to, the bacterial A site.
