Visualize the 3D structure of biomolecules

Contributed by: Soutick Saha, Jan Mangaldan and Jason Biggs

ResourceFunction["BioMoleculePlot3D"][biomol]

creates a three-dimensional visualization of the biomolecule represented by biomol.

Details and Options

ResourceFunction["BioMoleculePlot3D"] is also known as ribbon diagram, cartoon diagram or Richardson diagram.
biomol can be a four-character PDB ID represented as a string, a "Protein" Entity, a File pointing to a "PDB" or "MMCIF" file, or a URL.
ResourceFunction["BioMoleculePlot3D"] can visualize the location of individual residues along the backbone of the biomolecule, as well as α-helices and β-sheets in proteins.
If biomol corresponds to a nucleic acid (DNA or RNA) or a nucleic acid-protein complex, ResourceFunction["BioMoleculePlot3D"] shows a 3D structure indicating the purine and pyrimidine units in the nucleic acid components.
ResourceFunction["BioMoleculePlot3D"] has the same options as Graphics3D, with the following additions and changes:
"ChainStyle"Automaticdirectives to specify the style for each chain
"ColorScheme""Chain"color scheme used for biomolecule units
GeneratedAssetLocationAutomaticlocation where downloaded files are stored
"LigandStyle"Automaticstyle used for depicting the ligands
PlotLegendsNonelegends for biomolecule units
"ShowLigands"Falsewhether to show ligands
SourceLinkAutomaticPDB mirror used for getting PDB files
Downloaded files are stored in the directory returned by FileNameJoin[{$WolframDocumentsDirectory,"BioMolecule"}] by default. Use the option GeneratedAssetLocation to change the directory location.
Possible settings for "ColorScheme" include:
"Chain"color each chain, using "ChainStyle"
"Charge"color each residue by their charge or polarity
"Residue"color each residue
"SecondaryStructurePropensity"color each residue by their tendency to form helices or sheets
Possible settings for "LigandStyle" include "BallAndStick", "Spacefilling", "Tubes" and "Wireframe, with the default being Automatic.
Possible settings for SourceLink include "UnitedStates", "Europe" and "Japan", with the default being Automatic.
Some renderings might take a while, especially for first-time evaluations.
