    Description: The Escherichia coli catabolite activator protein (CAP) activates transcription at P(lac), P(gal), and other promoters through interactions with the RNA polymerase alpha subunit carboxyl-terminal domain (alphaCTD). We determined the crystal structure of the CAP-alphaCTD-DNA complex at a resolution of 3.1 angstroms. CAP makes direct protein-protein interactions with alphaCTD, and alphaCTD makes direct protein-DNA interactions with the DNA segment adjacent to the DNA site for CAP. There are no large-scale conformational changes in CAP and alphaCTD, and the interface between CAP and alphaCTD is small. These findings are consistent with the proposal that activation involves a simple "recruitment" mechanism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Benoff, Brian -- Yang, Huanwang -- Lawson, Catherine L -- Parkinson, Gary -- Liu, Jinsong -- Blatter, Erich -- Ebright, Yon W -- Berman, Helen M -- Ebright, Richard H -- GM21589/GM/NIGMS NIH HHS/ -- GM41376/GM/NIGMS NIH HHS/ -- GM64375/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2002 Aug 30;297(5586):1562-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Waksman Institute and Department of Chemistry, Howard Hughes Medical Institute, Rutgers University, Piscataway, NJ 08854, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12202833" target="_blank"〉PubMed〈/a〉

    Description: The structure of a protein triple helix has been determined at 1.9 angstrom resolution by x-ray crystallographic studies of a collagen-like peptide containing a single substitution of the consensus sequence. This peptide adopts a triple-helical structure that confirms the basic features determined from fiber diffraction studies on collagen: supercoiling of polyproline II helices and interchain hydrogen bonding that follows the model II of Rich and Crick. In addition, the structure provides new information concerning the nature of this protein fold. Each triple helix is surrounded by a cylinder of hydration, with an extensive hydrogen bonding network between water molecules and peptide acceptor groups. Hydroxyproline residues have a critical role in this water network. The interaxial spacing of triple helices in the crystal is similar to that in collagen fibrils, and the water networks linking adjacent triple helices in the crystal structure are likely to be present in connective tissues. The breaking of the repeating (X-Y-Gly)n pattern by a Gly--〉Ala substitution results in a subtle alteration of the conformation, with a local untwisting of the triple helix. At the substitution site, direct interchain hydrogen bonds are replaced with interstitial water bridges between the peptide groups. Similar conformational changes may occur in Gly--〉X mutated collagens responsible for the diseases osteogenesis imperfecta, chondrodysplasias, and Ehlers-Danlos syndrome IV.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bella, J -- Eaton, M -- Brodsky, B -- Berman, H M -- AR 19626/AR/NIAMS NIH HHS/ -- GM 21589/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Oct 7;266(5182):75-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Rutgers University, New Brunswick, NJ 08855.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7695699" target="_blank"〉PubMed〈/a〉

    Description: : The Research Collaboratory for Structural Bioinformatics Protein Data Bank (RCSB PDB) resource provides tools for query, analysis and visualization of the 3D structures in the PDB archive. As the mobile Web is starting to surpass desktop and laptop usage, scientists and educators are beginning to integrate mobile devices into their research and teaching. In response, we have developed the RCSB PDB Mobile app for the iOS and Android mobile platforms to enable fast and convenient access to RCSB PDB data and services. Using the app, users from the general public to expert researchers can quickly search and visualize biomolecules, and add personal annotations via the RCSB PDB’s integrated MyPDB service. Availability and implementation: RCSB PDB Mobile is freely available from the Apple App Store and Google Play ( http://www.rcsb.org ). Contact: pwrose@ucsd.edu

    Notes: Structures at atomic resolution (up to 1.0 Å) which contain bases, sugars or the phosphodiester linkage, were selected from the Nucleic Acid Database or the Cambridge Structural Database to build a nucleic acid dictionary from X-ray refined structures. The dictionary consists of the average values for bond distances, bond angles and dihedral angles. The variance of the sample is used to provide information about the expected r.m.s. deviations of the refined parameters. A dictionary was constructed for refinement trials in X-PLOR. The dictionary includes RNA and DNA in C2′-endo and C3′-endo sugar pucker conformations, as well as values for the backbone dihedrals. Tests were performed on the dictionary using three structures: a B-DNA, a Z-DNA and a protein-DNA complex. During the course of refinement, all three structures showed significant improvements as measured by r.m.s. deviations and R factors when compared to the previous DNA dictionary.
