    Description: The TRiC/CCT chaperonin is a 1-MDa hetero-oligomer of 16 subunits that assists the folding of proteins in eukaryotes. Low-resolution structural studies confirmed the TRiC particle to be composed of two stacked octameric rings enclosing a folding cavity. The exact arrangement of the different proteins in the rings underlies the functionality of TRiC and is likely to be conserved across all eukaryotes. Yet despite its importance it has not been determined conclusively, mainly because the different subunits appear nearly identical under low resolution. This work successfully addresses the arrangement problem by the emerging technique of cross-linking, mass spectrometry, and modeling. We cross-linked TRiC under native conditions with a cross-linker that is primarily reactive toward exposed lysine side chains that are spatially close in the context of the particle. Following digestion and mass spectrometry we were able to identify over 60 lysine pairs that underwent cross-linking, thus providing distance restraints between specific residues in the complex. Independently of the cross-link set, we constructed 40,320 (= 8 factorial) computational models of the TRiC particle, which exhaustively enumerate all the possible arrangements of the different subunits. When we assessed the compatibility of each model with the cross-link set, we discovered that one specific model is significantly more compatible than any other model. Furthermore, bootstrapping analysis confirmed that this model is 10 times more likely to result from this cross-link set than the next best-fitting model. Our subunit arrangement is very different than any of the previously reported models and changes the context of existing and future findings on TRiC.

    Description: Infectious diseases are the third leading cause of death in the United States and the leading cause worldwide. As the new millennium approaches, the public health community must replenish capacity depleted during years of inadequate funding while simultaneously incorporating new technologies and planning for the longer term. Among the challenges facing the public health community is the need for coordinated, global, multisectoral approaches to preventing and controlling complex infectious disease problems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Binder, S -- Levitt, A M -- Sacks, J J -- Hughes, J M -- New York, N.Y. -- Science. 1999 May 21;284(5418):1311-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Parasitic Diseases, National Center for Infectious Diseases (NCID), Centers for Disease Control and Prevention (CDC), F-22, 4770 Buford Highway, NE, Atlanta, GA 30341, USA. scb1@cdc.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10334978" target="_blank"〉PubMed〈/a〉

    Description: X-ray diffraction plays a pivotal role in the understanding of biological systems by revealing atomic structures of proteins, nucleic acids and their complexes, with much recent interest in very large assemblies like the ribosome. As crystals of such large assemblies often diffract weakly (resolution worse than 4 A), we need methods that work at such low resolution. In macromolecular assemblies, some of the components may be known at high resolution, whereas others are unknown: current refinement methods fail as they require a high-resolution starting structure for the entire complex. Determining the structure of such complexes, which are often of key biological importance, should be possible in principle as the number of independent diffraction intensities at a resolution better than 5 A generally exceeds the number of degrees of freedom. Here we introduce a method that adds specific information from known homologous structures but allows global and local deformations of these homology models. Our approach uses the observation that local protein structure tends to be conserved as sequence and function evolve. Cross-validation with R(free) (the free R-factor) determines the optimum deformation and influence of the homology model. For test cases at 3.5-5 A resolution with known structures at high resolution, our method gives significant improvements over conventional refinement in the model as monitored by coordinate accuracy, the definition of secondary structure and the quality of electron density maps. For re-refinements of a representative set of 19 low-resolution crystal structures from the Protein Data Bank, we find similar improvements. Thus, a structure derived from low-resolution diffraction data can have quality similar to a high-resolution structure. Our method is applicable to the study of weakly diffracting crystals using X-ray micro-diffraction as well as data from new X-ray light sources. Use of homology information is not restricted to X-ray crystallography and cryo-electron microscopy: as optical imaging advances to subnanometre resolution, it can use similar tools.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2859093/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2859093/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schroder, Gunnar F -- Levitt, Michael -- Brunger, Axel T -- EY016525/EY/NEI NIH HHS/ -- GM63718/GM/NIGMS NIH HHS/ -- R01 GM063817/GM/NIGMS NIH HHS/ -- U54 GM072970/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2010 Apr 22;464(7292):1218-22. doi: 10.1038/nature08892.

    Description: Group II chaperonins are essential mediators of cellular protein folding in eukaryotes and archaea. These oligomeric protein machines, approximately 1 megadalton, consist of two back-to-back rings encompassing a central cavity that accommodates polypeptide substrates. Chaperonin-mediated protein folding is critically dependent on the closure of a built-in lid, which is triggered by ATP hydrolysis. The structural rearrangements and molecular events leading to lid closure are still unknown. Here we report four single particle cryo-electron microscopy (cryo-EM) structures of Mm-cpn, an archaeal group II chaperonin, in the nucleotide-free (open) and nucleotide-induced (closed) states. The 4.3 A resolution of the closed conformation allowed building of the first ever atomic model directly from the single particle cryo-EM density map, in which we were able to visualize the nucleotide and more than 70% of the side chains. The model of the open conformation was obtained by using the deformable elastic network modelling with the 8 A resolution open-state cryo-EM density restraints. Together, the open and closed structures show how local conformational changes triggered by ATP hydrolysis lead to an alteration of intersubunit contacts within and across the rings, ultimately causing a rocking motion that closes the ring. Our analyses show that there is an intricate and unforeseen set of interactions controlling allosteric communication and inter-ring signalling, driving the conformational cycle of group II chaperonins. Beyond this, we anticipate that our methodology of combining single particle cryo-EM and computational modelling will become a powerful tool in the determination of atomic details involved in the dynamic processes of macromolecular machines in solution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2834796/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2834796/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Junjie -- Baker, Matthew L -- Schroder, Gunnar F -- Douglas, Nicholai R -- Reissmann, Stefanie -- Jakana, Joanita -- Dougherty, Matthew -- Fu, Caroline J -- Levitt, Michael -- Ludtke, Steven J -- Frydman, Judith -- Chiu, Wah -- P41 RR002250/RR/NCRR NIH HHS/ -- P41 RR002250-23/RR/NCRR NIH HHS/ -- P41 RR002250-237254/RR/NCRR NIH HHS/ -- P41 RR002250-24/RR/NCRR NIH HHS/ -- P41 RR002250-247897/RR/NCRR NIH HHS/ -- PN2 EY016525/EY/NEI NIH HHS/ -- PN2 EY016525-02S1/EY/NEI NIH HHS/ -- PN2 EY016525-03/EY/NEI NIH HHS/ -- PN2 EY016525-04/EY/NEI NIH HHS/ -- PN2 EY016525-05/EY/NEI NIH HHS/ -- R01 GM063817/GM/NIGMS NIH HHS/ -- R01 GM079429/GM/NIGMS NIH HHS/ -- R01 GM079429-03/GM/NIGMS NIH HHS/ -- R01 GM080139/GM/NIGMS NIH HHS/ -- R01 GM080139-03/GM/NIGMS NIH HHS/ -- R01 GM080139-04/GM/NIGMS NIH HHS/ -- R90 DK071504/DK/NIDDK NIH HHS/ -- R90 DK071504-03/DK/NIDDK NIH HHS/ -- T32 GM007276-30/GM/NIGMS NIH HHS/ -- T32 GM007276-31/GM/NIGMS NIH HHS/ -- England -- Nature. 2010 Jan 21;463(7279):379-83. doi: 10.1038/nature08701.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate Program in Structural and Computational Biology and Molecular Biophysics, Baylor College of Medicine, Houston, Texas 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20090755" target="_blank"〉PubMed〈/a〉

    Description: Allele loss is a hallmark of chromosome regions harboring recessive oncogenes. Lung cancer frequently demonstrates loss of heterozygosity on 17p. Recent evidence suggests that the p53 gene located on 17p13 has many features of such an antioncogene. The p53 gene was frequently mutated or inactivated in all types of human lung cancer. The genetic abnormalities of p53 include gross changes such as homozygous deletions and abnormally sized messenger RNAs along with a variety of point or small mutations, which map to the p53 open reading frame and change amino acid sequence in a region highly conserved between mouse and man. In addition, very low or absent expression of p53 messenger RNA in lung cancer cell lines compared to normal lung was seen. These findings, coupled with the previous demonstration of 17p allele loss in lung cancer, strongly implicate p53 as an anti-oncogene whose disruption is involved in the pathogenesis of human lung cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takahashi, T -- Nau, M M -- Chiba, I -- Birrer, M J -- Rosenberg, R K -- Vinocour, M -- Levitt, M -- Pass, H -- Gazdar, A F -- Minna, J D -- New York, N.Y. -- Science. 1989 Oct 27;246(4929):491-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Cancer Institute-Navy Medical Oncology Branch, Bethesda, MD 20814.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2554494" target="_blank"〉PubMed〈/a〉

    Description: Transcribing RNA polymerases oscillate between three stable states, two of which, pre- and posttranslocated, were previously subjected to x-ray crystal structure determination. We report here the crystal structure of RNA polymerase II in the third state, the reverse translocated, or "backtracked" state. The defining feature of the backtracked structure is a binding site for the first backtracked nucleotide. This binding site is occupied in case of nucleotide misincorporation in the RNA or damage to the DNA, and is termed the "P" site because it supports proofreading. The predominant mechanism of proofreading is the excision of a dinucleotide in the presence of the elongation factor SII (TFIIS). Structure determination of a cocrystal with TFIIS reveals a rearrangement whereby cleavage of the RNA may take place.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2718261/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2718261/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Dong -- Bushnell, David A -- Huang, Xuhui -- Westover, Kenneth D -- Levitt, Michael -- Kornberg, Roger D -- GM036559/GM/NIGMS NIH HHS/ -- GM041455/GM/NIGMS NIH HHS/ -- GM049985/GM/NIGMS NIH HHS/ -- K99 GM085136/GM/NIGMS NIH HHS/ -- K99 GM085136-01/GM/NIGMS NIH HHS/ -- R00 GM085136/GM/NIGMS NIH HHS/ -- R01 GM036659/GM/NIGMS NIH HHS/ -- R01 GM041455/GM/NIGMS NIH HHS/ -- R01 GM049985/GM/NIGMS NIH HHS/ -- R01 GM049985-16/GM/NIGMS NIH HHS/ -- R37 GM036659/GM/NIGMS NIH HHS/ -- R37 GM036659-22/GM/NIGMS NIH HHS/ -- R37 GM041455/GM/NIGMS NIH HHS/ -- R37 GM041455-20/GM/NIGMS NIH HHS/ -- U54 GM072970/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 May 29;324(5931):1203-6. doi: 10.1126/science.1168729.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Structural Biology, Stanford University School of Medicine, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19478184" target="_blank"〉PubMed〈/a〉

    Description: The protein density and arrangement of subunits of a complete, 32-protein, RNA polymerase II (pol II) transcription pre-initiation complex (PIC) were determined by means of cryogenic electron microscopy and a combination of chemical cross-linking and mass spectrometry. The PIC showed a marked division in two parts, one containing all the general transcription factors (GTFs) and the other pol II. Promoter DNA was associated only with the GTFs, suspended above the pol II cleft and not in contact with pol II. This structural principle of the PIC underlies its conversion to a transcriptionally active state; the PIC is poised for the formation of a transcription bubble and descent of the DNA into the pol II cleft.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4039082/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4039082/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Murakami, Kenji -- Elmlund, Hans -- Kalisman, Nir -- Bushnell, David A -- Adams, Christopher M -- Azubel, Maia -- Elmlund, Dominika -- Levi-Kalisman, Yael -- Liu, Xin -- Gibbons, Brian J -- Levitt, Michael -- Kornberg, Roger D -- AI21144/AI/NIAID NIH HHS/ -- GM063817/GM/NIGMS NIH HHS/ -- GM49885/GM/NIGMS NIH HHS/ -- R01 AI021144/AI/NIAID NIH HHS/ -- R01 GM036659/GM/NIGMS NIH HHS/ -- R01 GM063817/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2013 Nov 8;342(6159):1238724. doi: 10.1126/science.1238724.

    Description: Two methods have been used to measure the single-strand lengths of the DNA fragments produced by deoxyribonuclease I digestion of chromatin. The average lengths obtained are muliples of about 10.4 bases, significantly different from the value of 10 previously reported. This periodicity in fragment lengths is closely related to the periodicity of the DNA double helix in chromatin, but the two values need not be exactly the same.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Prunell, A -- Kornberg, R D -- Lutter, L -- Klug, A -- Levitt, M -- Crick, F H -- New York, N.Y. -- Science. 1979 May 25;204(4395):855-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/441739" target="_blank"〉PubMed〈/a〉

    Description: Predictions of the structures of the antigen-binding domains of an antibody, recorded before its experimental structure determination and tested subsequently, were based on comparative analysis of known antibody structures or on conformational energy calculations. The framework, the relative positions of the hypervariable regions, and the folds of four of the hypervariable loops were predicted correctly. This portion includes all residues in contact with the antigen, in this case hen egg white lysozyme, implying that the main chain conformation of the antibody combining site does not change upon ligation. The conformations of three residues in each of the other two hypervariable loops are different in the predicted models and the experimental structure.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chothia, C -- Lesk, A M -- Levitt, M -- Amit, A G -- Mariuzza, R A -- Phillips, S E -- Poljak, R J -- GM25435/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Aug 15;233(4765):755-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3090684" target="_blank"〉PubMed〈/a〉
