LIOTTA" Subject: CCL: re:rRNA summary To: "chemistry" Thank you to the various people who responded to the following message: >We would like to model the secondary structure of ribosomal >RNA and would like to contact anybody who has done similar >work or who can lead us to useful references. Are there any >crystollographic structures of rRNA available? Here is a summary of the responses: 1] "I have mostly used Michael Zukers MFold software to predict RNA secondary structure." ... and "Here is one paper:" Baldridge, G.D.; Dalton, M.W.; Fallon, A.M.; Is higher order Structure Conserved in Eukaryotic Ribosomal DNA Intergenic spacers?, Journal of Molecular Evolution, vol 35, (1992) Mark Dalton mwd %-% at %-% cray.com 2] "We are doing NMR spectroscopy of ions in ribosomal solutions, and would be interested in any information you get from the net about crystal structures etc.. of rRNA. A few articles that deal with ribosomal structure in general are: Crichton et al. 1977. PNAS 74:5547 Tardieu and Vachette 1982. EMBO J. 1?:35 Wittmann 1983. Ann. Rev. Biochem. 52:35" Harry J. Guttman guttman # - at - # poly.nn.wisc.edu 3] "Perhaps the following articles will be of interest: (a) Malhotra, Arun; Gabb, H.A; Harvey, S.C.; Modelling large nucleic -acids; Current Opinion in Structural Biology; vol 3 (2) p241-246 (1993)" (b) Malhotra, Arun; Tan, R.K.-Z.; Harvey, S.C.; Modelling large RNAs and ribonucleoprotein particles using molecular mechanics techniques, Biophysical Journal, vol 66; p1777-1795 (1994) Eberhard von Kitzing vkitzing |-at-| sunny.mpimf-Heidelberg.mpg.de 4] "There is extensive noncrystollographic work from the labs of Woese, Noller and Gutell. A quick medline search should turn these up. There is reasonable literature on ribosomal structure, by chemical cross- linking (labs of Wool and Wittman), electron micrography and maybe neutron scattering. There are probably some clues there. I doubt if there are crystals of isolated rRNAs, but if there are they should be in nucleic acids database (NDB) at Rutgers."
