引用 | ジャーナル: Cell / 年: 2000 タイトル: Solution structure of the E. coli 70S ribosome at 11.5 A resolution. 著者: I S Gabashvili / R K Agrawal / C M Spahn / R A Grassucci / D I Svergun / J Frank / P Penczek / 要旨: Over 73,000 projections of the E. coli ribosome bound with formyl-methionyl initiator tRNAf(Met) were used to obtain an 11.5 A cryo-electron microscopy map of the complex. This map allows ...Over 73,000 projections of the E. coli ribosome bound with formyl-methionyl initiator tRNAf(Met) were used to obtain an 11.5 A cryo-electron microscopy map of the complex. This map allows identification of RNA helices, peripheral proteins, and intersubunit bridges. Comparison of double-stranded RNA regions and positions of proteins identified in both cryo-EM and X-ray maps indicates good overall agreement but points to rearrangements of ribosomal components required for the subunit association. Fitting of known components of the 50S stalk base region into the map defines the architecture of the GTPase-associated center and reveals a major change in the orientation of the alpha-sarcin-ricin loop. Analysis of the bridging connections between the subunits provides insight into the dynamic signaling mechanism between the ribosomal subunits. #1: ジャーナル: Embo J. / 年: 1998 タイトル: The Crystal Structure of Ribosomal Protein S4 Reveals a Two-Domain Molecule with an Extensive RNA-Binding Surface: One Domain Shows Structural Homology to the Ets DNA-Binding Motif 著者: Davies, C. / Gerstner, R.B. / Draper, D.E. / Ramakrishnan, V. / White, S.W. #2: ジャーナル: Nature / 年: 1992 タイトル: The Structure of Ribosomal Protein S5 Reveals Sites of Interaction with 16S Rrna 著者: Ramakrishnan, V. / White, S.W. #3: ジャーナル: Embo J. / 年: 1994 タイトル: Crystal Structure of the Ribosomal Protein S6 from Thermus Thermophilus 著者: Lindahl, M. / Svensson, L.A. / Liljas, A. / Sedelnikova, I.A. / Eliseikina, I.A. / Fomenkova, N.P. / Nevskaya, N. / Nikonov, S.V. / Garber, M.B. / Muranova, T.A. / Rykonova, A.I. / Amons, R. #4: ジャーナル: Structure / 年: 1997 タイトル: The Structure of Ribosomal Protein S7 at 1.9 A Resolution Reveals a Beta- Hairpin Motif that Binds Double-Stranded Nucleic Acids 著者: Wimberly, B.T. / White, S.W. / Ramakrishnan, V. #5: ジャーナル: J.Mol.Biol. / 年: 1998 タイトル: Crystal Structure of Ribosomal Protein S8 from Thermus Thermophilus Reveals a High Degree of Structural Conservation of a Specific RNA Binding Site 著者: Nevskaya, N. / Tischenko, S. / Nikulin, A. / Al-Karadaghi, S. / Liljas, A. / Ehresmann, B. / Ehresmann, C. / Garber, M. / Nikonov, S. #6: ジャーナル: Structure / 年: 1998 タイトル: Conformational Variability of the N-Terminal Helix in the Structure of Ribosomal Protein S15 著者: Clemons Jr., W.M. / Davies, C.R. / White, S.W. / Ramakrishnan, V. #7: ジャーナル: Biochemistry / 年: 1996 タイトル: Solution Structure of Prokaryotic Ribosomal Protein S17 by High-Resolution NMR Spectroscopy 著者: Jaishree, T. / Ramakrishnan, V. / White, S.W. #8: ジャーナル: Nature / 年: 1999 タイトル: Structure of a bacterial 30S ribosomal subunit at 5.5 A resolution 著者: Clemons Jr., W.M. / May, J.L.C. / Wimberly, B.T. / Mccutcheon, J.P. / Capel, M.S. / Ramakrishnan, V. #9: ジャーナル: Embo J. / 年: 1993 タイトル: Ribosomal Protein L6: Structural Evidence of Gene Duplication from a Primitive RNA-Binding Protein 著者: Golden, B.L. / Davies, C. / Ramakrishnan, V. / White, S.W. #10: ジャーナル: Cell(Cambridge,Mass.) / 年: 1999 タイトル: A Detailed View of a Ribosomal Active Site: The Structure of the L11-RNA Complex 著者: Wimberly, B.T. / Guymon, R. / Mccutcheon, J.P. / Ramakrishnan, S.W. / White, V. #11: ジャーナル: J.Mol.Biol. / 年: 1999 タイトル: The Two Faces of the Escherichia Coli 23 S Rrna Sarcin/Ricin Domain: The Structure at 1.11 A Resolution 著者: Correll, C.C. / Wool, I.G. / Munishkin, A. #12: ジャーナル: Embo J. / 年: 1996 タイトル: Crystal Structure of the RNA Binding Ribosomal Prot L1 from Thermus Thermophilus 著者: Nikonov, S. / Nevskaya, N. / Eliseikina, I. / Briand, C. / Al-Karadaghi, S. / Svensson, A. / Liljas, A. / Aebarson, A. #13: ジャーナル: Embo J. / 年: 1998 タイトル: Crystal Structure of Methionyl-Trnafmet Transformylase Complexed with the Initiator Formyl-Methionyl-Trnafmet 著者: Schmitt, E. / Panvert, M. / Blanquet, S. / Mechulam, Y. | |||||||||
