Journal ArticleDOI
UCSF Chimera--a visualization system for exploratory research and analysis.
Eric F. Pettersen,Thomas D. Goddard,Conrad C. Huang,Gregory S. Couch,Daniel M. Greenblatt,Elaine C. Meng,Thomas E. Ferrin +6 more
TL;DR: Two unusual extensions are presented: Multiscale, which adds the ability to visualize large‐scale molecular assemblies such as viral coats, and Collaboratory, which allows researchers to share a Chimera session interactively despite being at separate locales.
Journal ArticleDOI
Crystal structure of the nucleosome core particle at 2.8 Å resolution
TL;DR: The X-ray crystal structure of the nucleosome core particle of chromatin shows in atomic detail how the histone protein octamer is assembled and how 146 base pairs of DNA are organized into a superhelix around it.
Journal ArticleDOI
The Amber biomolecular simulation programs
David A. Case,Thomas E. Cheatham,Tom Darden,Holger Gohlke,Ray Luo,Kenneth M. Merz,Alexey V. Onufriev,Carlos Simmerling,Bing Wang,Robert J. Woods +9 more
TL;DR: The development, current features, and some directions for future development of the Amber package of computer programs, which contains a group of programs embodying a number of powerful tools of modern computational chemistry, focused on molecular dynamics and free energy calculations of proteins, nucleic acids, and carbohydrates.
Journal ArticleDOI
MOLMOL: a program for display and analysis of macromolecular structures.
TL;DR: Special efforts were made to allow for appropriate display and analysis of the sets of typically 20-40 conformers that are conventionally used to represent the result of an NMR structure determination, using functions for superimposing sets of conformers, calculation of root mean square distance (RMSD) values, identification of hydrogen bonds, and identification and listing of short distances between pairs of hydrogen atoms.
Journal ArticleDOI
A well-behaved electrostatic potential based method using charge restraints for deriving atomic charges: the RESP model
TL;DR: In this paper, the authors present an approach to generate electrostatic potential (ESP) derived charges for molecules, which optimally reproduce the intermolecular interaction properties of molecules with a simple two-body additive potential, provided that a suitably accurate level of quantum mechanical calculation is used to derive the ESP around the molecule.

The Protein Data Bank: a computer-based archival file for macromolecular structures.
Frances C. Bernstein,Thomas F. Koetzle,Graheme J. B. Williams,Edgar F. Meyer,Michael D. Brice,John R. Rodgers,O. Kennard,Takehiko Shimanouchi,Mitsuo Tasumi +8 more
TL;DR: The Protein Data Bank is a computer-based archival file for macromolecular structures that stores in a uniform format atomic co-ordinates and partial bond connectivities, as derived from crystallographic studies.
Journal ArticleDOI
The interpretation of protein structures: estimation of static accessibility.
B. Lee,Frederic M. Richards +1 more
TL;DR: The accessibility of atoms in the twenty common amino acids in model tripeptides of the type Ala-X-Ala are given for defined conformation and the larger non-polar amino acids tend to be more “buried” in the native form of all three proteins.
Journal ArticleDOI
Solvent-Accessible Surfaces of Proteins and Nucleic Acids
TL;DR: A method is presented for analytically calculating a smooth, three-dimensional contour about a molecule, which has been applied in enzymology, rational drug design, immunology, and understanding DNA base sequence recognition.
Yacc : Yet Another Compiler Compiler
S. C. Johnson,Murray Hill +1 more
TL;DR: Yacc provides a general tool for describing the input to a computer program, together with code to be invoked as each such structure is recognized, and turns such a specification into a subroutine that handles the input process.

The UNIX time-sharing system
Dennis M. Ritchie,Ken Thompson +1 more
TL;DR: The nature and implementation of the file system and of the user command interface are discussed, including the ability to initiate asynchronous processes and over 100 subsystems including a dozen languages.
