Example of AGP-RNA complex three-dimensional structure, HNA: RNA complex. A: Precise orientation of HNA (in skeleton scheme) wound around the single-stranded RNA structure (green cartooned color); B: Representation of HNA interaction with RNA backbone; C: This shows the hydrogen bonding between RNA (in white) and HNA (in cyan). The HNA is labeled according to the scheme (h-base-α in the structure where h = anhydrohexitol, Base = AGTC nitrogenous base, α = position of residues in the complex structure). PDBID:1EJZ [47]
