What is RasMol used for?
RasMol is a computer program written for molecular graphics visualization intended and used primarily for the depiction and exploration of biological macromolecule structures, such as those found in the Protein Data Bank.
What is electrostatic surface potential?
Electrostatic potential maps, also known as electrostatic potential energy maps, or molecular electrical potential surfaces, illustrate the charge distributions of molecules three dimensionally. These maps allow us to visualize variably charged regions of a molecule.
How do you cite PyMOL?
How does one cite PyMOL? There are no peer reviewed publications on PyMOL yet. So, if your journal is hip enough to allow URL citations, please cite PyMOL as: The PyMOL Molecular Graphics System, Version 1.2r3pre, Schrödinger, LLC.
What do the colors in the molecular electrostatic potential mean?
The electrostatic potential at different points on the electron density isosurface is shown by coloring the isosurface with contours. The more red / blue differences, the more polar the molecule. If the surface is largely white or lighter color shades, the molecule is mostly non-polar.
How do you show cavities in PyMOL?
To display the external surface of interior cavities and pockets, click on Setting -> Surface -> Cavities & Pockets Only.
What is another name for electrostatic potential?
The electric potential (also called the electric field potential, potential drop, the electrostatic potential) is the amount of work energy needed to move a unit of electric charge from a reference point to the specific point in an electric field with negligible acceleration of the test charge to avoid producing …
How to calculate electrostatic potential using PyMOL plugin?

Is there an APBS plugin for PyMOL electrostatics?
The APBS Electrostatics Plugin integrates the APBS software package into PyMOL. Its primary purpose is electrostatic surface visualization. It superseedes the APBS Tool2.1 plugin.
What are the colors of electrostatic surfaces with PyMOL?
Electrostatic Potential Surfaces with PyMOL. As the color legend indicates, the red color (negative potential) arises from an excess of negative charges near the surface and the blue color (positive potential) occurs when the surface is positively charged. The white regions correspond to fairly neutral potentials.
How is the positive charge on A PyMOL surface created?
We suspect that the positive charge on the surface patch is created by positively charged side chains (Lys, Arg, or His) so we will render them in a more prominent fashion. Enter the following commands in bold in the PyMOL console:
