(A) ADAR-catalyzed deamination of adenosine to inosine in RNA changes the H-bonding potential of the modified nucleobase. (B) Hydrogen bonding patterns for G–C, I–C, and A–U Watson–Crick base pairs. (C) Hydrogen bonding patterns for G–U, I–U, and I–A wobble base pairs. H-bonds are shown as dashed lines.
