    Structural basis of transcription activation: the CAP-alpha CTD-DNA complex (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-08-31
    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〉

    EMDataBank unified data resource for 3DEM (2016)
    Oxford University Press
    Details
    Publication Date: 2016-01-07
    Description: Three-dimensional Electron Microscopy (3DEM) has become a key experimental method in structural biology for a broad spectrum of biological specimens from molecules to cells. The EMDataBank project provides a unified portal for deposition, retrieval and analysis of 3DEM density maps, atomic models and associated metadata ( emdatabank.org ). We provide here an overview of the rapidly growing 3DEM structural data archives, which include maps in EM Data Bank and map-derived models in the Protein Data Bank. In addition, we describe progress and approaches toward development of validation protocols and methods, working with the scientific community, in order to create a validation pipeline for 3DEM data.

    An initial feasibility stage for Stoer's constrained least squares algorithm (1975)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: A procedure is described for computing an initial feasible vector, x sub 0, for Stoer's algorithm for solving the linear least squares problem subject to linear equality and inequality constraints. The procedure described fits well with Stoer's algorithm since much of the computation performed to determine x sub 0 accomplishes initializing transformations of the problem data, which would otherwise be done in Stoer's algorithm after being given an x sub 0.

    Basic linear algebra subprograms for FORTRAN usage (1977)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: A package of 38 low level subprograms for many of the basic operations of numerical linear algebra is presented. The package is intended to be used with FORTRAN. The operations in the package are dot products, elementary vector operations, Givens transformations, vector copy and swap, vector norms, vector scaling, and the indices of components of largest magnitude. The subprograms and a test driver are available in portable FORTRAN. Versions of the subprograms are also provided in assembly language for the IBM 360/67, the CDC 6600 and CDC 7600, and the Univac 1108.

    C super 1: Compatible interpolation over a triangle (1976)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: An elementary derivation and a complete description is given of an algorithm for interpolation over a plane triangle when function values and first partial derivatives are given at the vertices. The method gives C1 continuity with neighboring triangles. The interpolation method is mathematically equivalent to one that has been discussed previously in the literature; however, the algorithmic form given here is more efficient than has previously been described.

    Software for C1 interpolation (1977)
    In:  CASI
    Details
    Publication Date: 2019-07-13
    Description: The problem of mathematically defining a smooth surface, passing through a finite set of given points is studied. Literature relating to the problem is briefly reviewed. An algorithm is described that first constructs a triangular grid in the (x,y) domain, and first partial derivatives at the modal points are estimated. Interpolation in the triangular cells using a method that gives C sup.1 continuity overall is examined. Performance of software implementing the algorithm is discussed. Theoretical results are presented that provide valuable guidance in the development of algorithms for constructing triangular grids.
