ItProvides graphical interfaces for the PSI88 molecular orbital plotting package and BOSS and MCPRO. In addition, it offers a variety of other useful features such as drawing ofCommon geometrical objects, formatting of text, and interactive display of molecular orbitals and electron densities. ChemEdit is designed mainly to help scientists in theTask of drawing and designing chemical structures.
As a programming language, it is not a solution or program in itself, but rather provides an environment that eases many of the bookkeeping tasks involved in writing programs that manipulate three-dimensional structural models.View Application Entry for NAB (Nucleic Acid Builder)Nucleic Acid MOdeling Tool(NAMOT) is a graphic tool to build and manipulate nucleic acid structures. We expect nab to be useful in model building and coordinate manipulation of proteins and nucleic acids, ranging in size from fairly small systems to the largest systems for which an atomic level of description makes good computational sense. Nab uses a C-like syntax for variables, expressions and control structures (if, for, while) and has extensions for operating on molecules (new types and a large number of builtins for providing the necessary operations). It can be installed on Windows 95/98/NT 4.0 or Power Macintosh comuters.NAB is a high-level language that facilitates manipulations of macromolecules and their fragments. Graphics can be exported to variousHIC-Up (Hetero-compound Information Centre - Uppsala)HIC-Up (The Hetero-compound Information Centre - Uppsala) is a freely accessibleResource for structural biologists who are dealing with hetero-compounds (smallView Application Entry for HIC-Up (Hetero-compound Information Centre - Uppsala)ISIS/Draw is a chemically intelligent drawing package that enables you to draw chemical structures using the same intuitive signs and symbols used for paper sketches.
PDB, AMBER, and parameter formats can be used as both input and output.View Application Entry for NAMOT (Nucleic Acid MOdeling Tool)Simulaid can perform many Confersion, Analysis and General operations such as- Find optimal centering of a solute (finds the center of the smallest enclosing sphere of the solute)- Find optimal orientation of a solute in a cube or a rectangle (finds the orientation that results in the smallest enclosing cube or rectangle of the solute). NAMOT produces graphic output in PS and PPMFormats. Both Motif and XView interfaces exist, allowing NAMOT to run on most UNIX workstations. The graphic user interface attempts to make the program as efficient as possible while still retaining the power ofThe parameter set. NAMOT2 features a set of user modifiable libraries that provide flexibility forUsers to expand NAMOT2 to fit their research needs. Use of theseReduced coordinates provide a powerful and intuitive interface to nucleic acid structure.
A simple Coulombic formula is usedAll the constants are dropped out from this formula, resulting in some weird energy units that does not matter for the purpose ofEnergy comparison. The energy is re-computed after placement of each ion. The ions are placed in the nodes of a cubic grid, in which the electrostaticEnergy achieves the smallest values. Dat, as well as some Insight free formats.- Make atomnames conform to Brookhaven conventions (e.g., HH12 -> 2HH1)- Convert atom and residue names among Charmm, Amber, Moil, ChemX, and PDB conventions.- Generate a list of 1-4 distances and torsion anglesThis program places the required number of sodium ions around a system of electric charges, e.g., the atoms of a biologicalMacromolecule (protein, DNA, protein/DNA complex). CRD, Brookhaven PDB, Charmm PDB (different segid location), Insight.
The electrostatic potential map, pre-computed by DelPhi, is used to replace a certain number of water molecules of the bath, surrounding a solvated macromolecule, with ions. The purpose of this server is to make Protein Modelling accessible to all biochemists and molecular biologists World Wide.Wat2ions is complementary to DelPhi, the renowned solver of the Poisson-Boltzmann equation (). TrivialModifications to the program should allow the placement of any combination of multivalent ions of different charges.SOLVATE is a program to construct an atomic solvent environment model for a given atomic macromolecule model (solute) for use in molecular dynamicsSWISS-MODEL is an Automated Protein Modelling Server running at the GlaxoWellcome Experimental Research in Geneva, Switzerland. It isRecommended that the placed ions are equilibrated in a separate Monte Carlo or Molecular Dynamics simulation. The coordinates of the placed ions are printed out in the PDB format for further usage. The resulting error is believed to be minor, compared to that resulting from the one-by-one ions placement, orFrom using the simplified energy function.

To avoid placing ions too close to the macromolecule, the potential map should be pre-computed taking into account the ion-free Stern layer around the macromolecule (see DelPhi manual for further details). No two ions are placed closer than a certain distance to each other. The waters with the largest potential are replaced with chlorides, and the waters with the smallest potential, with sodii.
