S8–RNA interactions. (A) Surface contacts between E. coli S8 (purple) and mRNA1a (green). Buried surface area on the mRNA is shown in dark green and buried surface from S8 is shown in dark purple. (B) Hydrogen bonding between E. coli S8 and its spc operon mRNA-binding site. Two base-specific hydrogen bonds occur (Y85:G37, and S104:A14). All other protein hydrogen bonds involve phosphates or sugars. (C) A comparison of RNA–protein interactions between E. coli S8/mRNA (blue) and T. thermophilus S8/rRNA (orange). Phosphorus atoms and Cα atoms shown were used for the superposition.
