Structure of 7S.S RNA. (A) Secondary structure of 7S RNA with the approximate positions of SRP19 and SRP54M indicated. The nucleotide sequence and 2D-topology diagram of the 7S.S RNA fragment used for crystallization are given. The numbering corresponds to full-length M. jannaschii 7S RNA. Lines between bases indicate WC base pairs, open circles noncanonical pairs, and filled circles tertiary RNA–RNA interactions. Nucleotides of particular interest are highlighted in red. (B) Ribbon representation of free M. jannaschii 7S.S RNA colored as in A. (C) 7S.S RNA in complex with SRP19 (PDB code 1LNG; Hainzl et al. 2002).
