The MIRAS map in the crown view at 14 Å resolution shown in stereo from the side opposite the 30S subunit. Previously indetified features such as ribosomal protein L1, L7/L12 region, and 5S ribosomal RNA in the central protuberance are labeled. To show the underlying strut-like architecture, the map is contoured at a high-density level and all density not connected has been moved.
