(A) Probability distribution in the location of the side chain in the i6A hypermodified nucleobase at the 37th position in E. coli tRNA. (B) Overlays of i6A, io6A, or ms2i6A modified nucleobases in tRNA with respect to the nucleobase ring for structures taken at 5 ns intervals over the MD simulations. (C) Average structural deviation of anticodon nucleotides (RMSF, Å) over the MD simulations with respect to the initial structure for each i6A modified tRNA compared to unmodified A-tRNA.
