    Assembly reflects evolution of protein complexes (2008)
    Nature Publishing Group (NPG)

    Publication Date: 2008-06-20
    Description: A homomer is formed by self-interacting copies of a protein unit. This is functionally important, as in allostery, and structurally crucial because mis-assembly of homomers is implicated in disease. Homomers are widespread, with 50-70% of proteins with a known quaternary state assembling into such structures. Despite their prevalence, their role in the evolution of cellular machinery and the potential for their use in the design of new molecular machines, little is known about the mechanisms that drive formation of homomers at the level of evolution and assembly in the cell. Here we present an analysis of over 5,000 unique atomic structures and show that the quaternary structure of homomers is conserved in over 70% of protein pairs sharing as little as 30% sequence identity. Where quaternary structure is not conserved among the members of a protein family, a detailed investigation revealed well-defined evolutionary pathways by which proteins transit between different quaternary structure types. Furthermore, we show by perturbing subunit interfaces within complexes and by mass spectrometry analysis, that the (dis)assembly pathway mimics the evolutionary pathway. These data represent a molecular analogy to Haeckel's evolutionary paradigm of embryonic development, where an intermediate in the assembly of a complex represents a form that appeared in its own evolutionary history. Our model of self-assembly allows reliable prediction of evolution and assembly of a complex solely from its crystal structure.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2658002/" 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/PMC2658002/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levy, Emmanuel D -- Boeri Erba, Elisabetta -- Robinson, Carol V -- Teichmann, Sarah A -- MC_U105161047/Medical Research Council/United Kingdom -- U.1051.04.025(78835)/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- England -- Nature. 2008 Jun 26;453(7199):1262-5. doi: 10.1038/nature06942.

    Recognition of a signal peptide by the signal recognition particle (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-04-07
    Description: Targeting of proteins to appropriate subcellular compartments is a crucial process in all living cells. Secretory and membrane proteins usually contain an amino-terminal signal peptide, which is recognized by the signal recognition particle (SRP) when nascent polypeptide chains emerge from the ribosome. The SRP-ribosome nascent chain complex is then targeted through its GTP-dependent interaction with SRP receptor to the protein-conducting channel on endoplasmic reticulum membrane in eukaryotes or plasma membrane in bacteria. A universally conserved component of SRP (refs 1, 2), SRP54 or its bacterial homologue, fifty-four homologue (Ffh), binds the signal peptides, which have a highly divergent sequence divisible into a positively charged n-region, an h-region commonly containing 8-20 hydrophobic residues and a polar c-region. No structure has been reported that exemplifies SRP54 binding of any signal sequence. Here we have produced a fusion protein between Sulfolobus solfataricus SRP54 (Ffh) and a signal peptide connected via a flexible linker. This fusion protein oligomerizes in solution through interaction between the SRP54 and signal peptide moieties belonging to different chains, and it is functional, as demonstrated by its ability to bind SRP RNA and SRP receptor FtsY. We present the crystal structure at 3.5 A resolution of an SRP54-signal peptide complex in the dimer, which reveals how a signal sequence is recognized by SRP54.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2897128/" 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/PMC2897128/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Janda, Claudia Y -- Li, Jade -- Oubridge, Chris -- Hernandez, Helena -- Robinson, Carol V -- Nagai, Kiyoshi -- MC_U105184330/Medical Research Council/United Kingdom -- U.1051.04.016(78933)/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- England -- Nature. 2010 May 27;465(7297):507-10. doi: 10.1038/nature08870.

    Micelles protect membrane complexes from solution to vacuum (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-06-17
    Description: The ability to maintain interactions between soluble protein subunits in the gas phase of a mass spectrometer gives critical insight into the stoichiometry and interaction networks of protein complexes. Conversely, for membrane protein complexes in micelles, the transition into the gas phase usually leads to the disruption of interactions, particularly between cytoplasmic and membrane subunits, and a mass spectrum dominated by large aggregates of detergent molecules. We show that by applying nanoelectrospray to a micellar solution of a membrane protein complex, the heteromeric adenosine 5'-triphosphate (ATP)-binding cassette transporter BtuC2D2, we can maintain the complex intact in the gas phase of a mass spectrometer. Dissociation of either transmembrane (BtuC) or cytoplasmic (BtuD) subunits uncovers modifications to the transmembrane subunits and cooperative binding of ATP. By protecting a membrane protein complex within a n-dodecyl-beta-d-maltoside micelle, we demonstrated a powerful strategy that will enable the subunit stoichiometry and ligand-binding properties of membrane complexes to be determined directly, by precise determination of the masses of intact complexes and dissociated subunits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barrera, Nelson P -- Di Bartolo, Natalie -- Booth, Paula J -- Robinson, Carol V -- Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2008 Jul 11;321(5886):243-6. doi: 10.1126/science.1159292.

    Structures of SAS-6 suggest its organization in centrioles (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-01-29
    Description: Centrioles are cylindrical, ninefold symmetrical structures with peripheral triplet microtubules strictly required to template cilia and flagella. The highly conserved protein SAS-6 constitutes the center of the cartwheel assembly that scaffolds centrioles early in their biogenesis. We determined the x-ray structure of the amino-terminal domain of SAS-6 from zebrafish, and we show that recombinant SAS-6 self-associates in vitro into assemblies that resemble cartwheel centers. Point mutations are consistent with the notion that centriole formation in vivo depends on the interactions that define the self-assemblies observed here. Thus, these interactions are probably essential to the structural organization of cartwheel centers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉van Breugel, Mark -- Hirono, Masafumi -- Andreeva, Antonina -- Yanagisawa, Haru-aki -- Yamaguchi, Shoko -- Nakazawa, Yuki -- Morgner, Nina -- Petrovich, Miriana -- Ebong, Ima-Obong -- Robinson, Carol V -- Johnson, Christopher M -- Veprintsev, Dmitry -- Zuber, Benoit -- MC_U105184294/Medical Research Council/United Kingdom -- MC_U105192716/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2011 Mar 4;331(6021):1196-9. doi: 10.1126/science.1199325.

    Intrinsically disordered protein threads through the bacterial outer-membrane porin OmpF (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-07-03
    Description: Porins are beta-barrel outer-membrane proteins through which small solutes and metabolites diffuse that are also exploited during cell death. We have studied how the bacteriocin colicin E9 (ColE9) assembles a cytotoxic translocon at the surface of Escherichia coli that incorporates the trimeric porin OmpF. Formation of the translocon involved ColE9's unstructured N-terminal domain threading in opposite directions through two OmpF subunits, capturing its target TolB on the other side of the membrane in a fixed orientation that triggers colicin import. Thus, an intrinsically disordered protein can tunnel through the narrow pores of an oligomeric porin to deliver an epitope signal to the cell to initiate cell death.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3856478/" 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/PMC3856478/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Housden, Nicholas G -- Hopper, Jonathan T S -- Lukoyanova, Natalya -- Rodriguez-Larrea, David -- Wojdyla, Justyna A -- Klein, Alexander -- Kaminska, Renata -- Bayley, Hagan -- Saibil, Helen R -- Robinson, Carol V -- Kleanthous, Colin -- 079605/Wellcome Trust/United Kingdom -- 079605/2/06/2/Wellcome Trust/United Kingdom -- 082045/Wellcome Trust/United Kingdom -- 294408/European Research Council/International -- BB/D008573/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/D00873/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/G020671/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- G1000819/Medical Research Council/United Kingdom -- R0I HG003709/HG/NHGRI NIH HHS/ -- WT082045/Wellcome Trust/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2013 Jun 28;340(6140):1570-4. doi: 10.1126/science.1237864.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Oxford, South Parks Road, Oxford OX1 3QU, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23812713" target="_blank"〉PubMed〈/a〉

    Structural insights into the activity of enhancer-binding proteins (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-03-26
    Description: Activators of bacterial sigma54-RNA polymerase holoenzyme are mechanochemical proteins that use adenosine triphosphate (ATP) hydrolysis to activate transcription. We have determined by cryogenic electron microscopy (cryo-EM) a 20 angstrom resolution structure of an activator, phage shock protein F [PspF(1-275)], which is bound to an ATP transition state analog in complex with its basal factor, sigma54. By fitting the crystal structure of PspF(1-275) at 1.75 angstroms into the EM map, we identified two loops involved in binding sigma54. Comparing enhancer-binding structures in different nucleotide states and mutational analysis led us to propose nucleotide-dependent conformational changes that free the loops for association with sigma54.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2756573/" 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/PMC2756573/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rappas, Mathieu -- Schumacher, Jorg -- Beuron, Fabienne -- Niwa, Hajime -- Bordes, Patricia -- Wigneshweraraj, Sivaramesh -- Keetch, Catherine A -- Robinson, Carol V -- Buck, Martin -- Zhang, Xiaodong -- B17129/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2005 Mar 25;307(5717):1972-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Imperial College London, London, SW7 2AZ, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15790859" target="_blank"〉PubMed〈/a〉

    Evidence for macromolecular protein rings in the absence of bulk water (2005)

    Publication Date: 2005-11-19
    Description: We have examined the architecture of a protein complex in the absence of bulk water. By determining collision cross sections of assemblies of the trp RNA binding protein, TRAP, we established that the 11-membered ring topology of the complex can be maintained within a mass spectrometer. We also found that the binding of tryptophan enhances the stability of the ring structure and that addition of a specific RNA molecule increases the size of the complex and prevents structural collapse. These results provide definitive evidence that protein quaternary structure can be maintained in the absence of bulk water and highlight the potential of ion mobility separation for defining shapes of heterogeneous macromolecular assemblies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ruotolo, Brandon T -- Giles, Kevin -- Campuzano, Iain -- Sandercock, Alan M -- Bateman, Robert H -- Robinson, Carol V -- New York, N.Y. -- Science. 2005 Dec 9;310(5754):1658-61.

    Structural basis for the subunit assembly of the anaphase-promoting complex (2011)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2011-02-11
    Description: The anaphase-promoting complex or cyclosome (APC/C) is an unusually large E3 ubiquitin ligase responsible for regulating defined cell cycle transitions. Information on how its 13 constituent proteins are assembled, and how they interact with co-activators, substrates and regulatory proteins is limited. Here, we describe a recombinant expression system that allows the reconstitution of holo APC/C and its sub-complexes that, when combined with electron microscopy, mass spectrometry and docking of crystallographic and homology-derived coordinates, provides a precise definition of the organization and structure of all essential APC/C subunits, resulting in a pseudo-atomic model for 70% of the APC/C. A lattice-like appearance of the APC/C is generated by multiple repeat motifs of most APC/C subunits. Three conserved tetratricopeptide repeat (TPR) subunits (Cdc16, Cdc23 and Cdc27) share related superhelical homo-dimeric architectures that assemble to generate a quasi-symmetrical structure. Our structure explains how this TPR sub-complex, together with additional scaffolding subunits (Apc1, Apc4 and Apc5), coordinate the juxtaposition of the catalytic and substrate recognition module (Apc2, Apc11 and Apc10 (also known as Doc1)), and TPR-phosphorylation sites, relative to co-activator, regulatory proteins and substrates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schreiber, Anne -- Stengel, Florian -- Zhang, Ziguo -- Enchev, Radoslav I -- Kong, Eric H -- Morris, Edward P -- Robinson, Carol V -- da Fonseca, Paula C A -- Barford, David -- Cancer Research UK/United Kingdom -- England -- Nature. 2011 Feb 10;470(7333):227-32. doi: 10.1038/nature09756.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Structural Biology, Institute of Cancer Research, Chester Beatty Laboratories, 237 Fulham Road, London, SW3 6JB, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21307936" target="_blank"〉PubMed〈/a〉
