Publication Abstract from PubMed We have determined the solution structure of ribosomal protein L18 from Thermus thermophilus. L18 is a 12.5 kDa protein of the large subunit of the ribosome and binds to both 5 S and 23 S rRNA. In the uncomplexed state L18 folds to a mixed alpha/beta globular structure with a long disordered N-terminal region. We compared our high-resolution structure with RNA-complexed L18 from Haloarcula marismortui and T. thermophilus to examine RNA-induced as well as species-dependent structural differences. We also identified T. thermophilus S11 as a structural homologue and found that the structures of the RNA-recognition sites are conserved. Important features, for instance a bulge in the RNA-contacting beta-sheet, are conserved in both proteins. We suggest that the L18 fold recognizes a specific RNA motif and that the resulting RNA-protein-recognition module is tolerant to variations in sequence. The solution structure of ribosomal protein L18 from Thermus thermophilus reveals a conserved RNA-binding fold.,Woestenenk EA, Gongadze GM, Shcherbakov DV, Rak AV, Garber MB, Hard T, Berglund H Biochem J. 2002 May 1;363(Pt 3):553-61.
