Sequences of the (A) N1 riboswitch and (B) bacterial decoding A-site. (CD) Crucial contacts of aminoglycoside 6′ group within A-site from the crystal structures (NEO complex, PDB ID 2ET4 (51), PAR complex: 1J7T (52)) and optimization protocol with hydrogen atoms of (53). (EF) Two conformations of U1406 and U1495 found in the crystal structures of the A-site – PAR complex, PDB ID 1J7T and A-site – modified PAR complex, PDB ID 2BEE (54). Distances between non-hydrogen atoms are in Å. One crystal water molecule found close to uridines in the PAR complex is shown as a red sphere.
