PyMOL

Overview

PyMOL is an open-source molecular visualization program functioning on a variety of computer platforms (Windows, Mac, Linux/UNIX, etc). The software is indeed is an open-source and is released under the BSDL OSI-approved license. PyMOL is capable of generating high resolution images for publishing or printing, making movies and much more. PyMOL is robust, fast and extensible. The PyMOLWiki comes with many scripts to extend the features in PyMOL.

PyMOL currently holds a large percentage of the high-quality images published in scholarly journals like Science and Nature. PyMOL images frequently grace the covers of high impact journals.

Features

PyMol can be used for:

·        Viewing 3D Molecular Structures

·        Modeling and editing structures

·        Editing Atoms

·        Molecular sculpting

·        Homology modeling

·        Animating Molecules Dynamically

·        Making high quality images and movies

o       Image Manipulation

o       Labels

o       Photoshop/GIMP

o       Stereo Figures

o       Publication-quality images

o       PovRay

·        Exporting Geometry: VRML, IDTF

Plugins and scripts

PyMOL can be integrated seamlessly with MS Powerpoint. For this is used Axpymol - PyMOL ActiveX control.

There are a lot of scripts and plugins ready for use for this product. Among them are such as

 -  CAVER - provides rapid, accurate and fully automated calculation of pathways leading from buried cavities to outside solvent in static and dynamic protein structures. Study of these pathways is important in drug design and molecular enzymology to understand binding of inhibitors to the receptors, substrate binding and product egress from the enzyme active sites. Calculated pathways can be visualized by graphic program PyMol dissecting anatomy and dynamics of entrance tunnels. CAVER allows analysis of any molecular structure including proteins, nucleic acids, inorganic materials, etc.

CAVER Viewer enables efficient visualization of calculated pathways and can be run online using Java Web Start technology.

-   APBS, the Adaptive Poisson-Boltzmann Solver, is a freely available macromolecular electrostatics calculation program released under the GPL. It is a cost-effective but uncompromised alternative to GRASP, and it can be used within pymol. Pymol can display the results of the calculations as an electrostatic potential molecular surface.

PyMol currently supports the APBS plugin written by Michael Lerner. This plugin makes it possible to run APBS from within PyMOL, and then display the results as a color-coded electrostatic surface (units KbT / ec) in the molecular display window (as with the image to the right).

Some of PyMol integrations

  1. Nuccyl -- Nuccyl is a great PyMol extension
  2. CASTp -- Binding and Active site prediction
  3. CCTBX -- Computational Crystallography Toolbox

Part of PyMOL's popularity comes from the fact that it is very flexible and it offers arbitrarily high-resolution images as output; this make it a great tool for making journal covers or any press-related images.

Coot - Crystallographic Object-Oriented Toolkit

Overview

Coot is for model building, model completion and validation.

Coot displays maps and models and allows model manipulations such as idealization, real space refinement, manual rotation/translation, rigid-body fitting, ligand search, solvation, mutations, rotamers, Ramachandran plots and so on. Coot has some features that resemble those of Frodo, O, Quanta and XtalView's XFit. It is a completely independent system of course. Coot doesn't do many aspects of structure represention
