Figures
This section illustrates the figure-creation process, from initial conception → final multi-panel figure ready for publication. Organized as various "case studies" that are representative of the tasks typically faced by structural or computational biologists, this section provides several step-by-step examples. These examples are entirely self-contained, and the materials include everything from (i) raw, starting data (e.g., PDB files) to (ii) actual, working PyMOL or Python scripts and (iii) final output image files.
Case 1: Overall fold / domain level (≥ novice/intermediate)
Illustration of the overall fold of carbonic anhydrase, CsoS3, from Halothiobacillus neapolitanus.(PDB ID 2G13). The three domains that compose this enzyme are distinguished by coloring each domain separately (blue, yellow, red). The orientation was chosen to feature the location of the active site (outlined by side chains and zinc ion), and to show the two-fold symmetry relationship between the active domain (yellow) and homologous but defunct domain (red). SSEs are labeled directly on the individual SSEs. Domain labels are colored to correspond to the domains they are labeling. Labels in the active site are given an “outer glow” to make them legible in a region of the figure that is dense in detail. Depth is conveyed by use of fog, veiling less important structural features in the back of the enzyme.
Ingredients for this figure:
1) Download Coordinates
2) Download Pymol script
3) Run Pymol script

Case 2: Ligand-binding sites (≥ novice/intermediate)
Illustration of the active site of dUTPase from Mycobacterium tuberculosis (PDB ID 1SIX). The orientation of the active site was chosen to feature the geometry of the chemical reaction catalyzed by this enzyme, specifically the in-line nucleophilic attack of water 212 on the alpha-phosphate of dUTP. Fine tuning of the orientation was made to eliminate overlap of side chains and to make all hydrogen bonds (dashed lines) visible. Only side chains directly involved in catalysis are depicted. Carbons are colored according to five conserved motifs of the dUTPase family. Non-conserved residues are given an undistracting gray color and are veiled in fog. Labels were colored to correspond to the side chains they are labeling.

Case 3: Structure alignment (≥ novice/intermediate)
An overlay of five simvastatin synthetase crystal structures illustrating degrees of hinge closing imparted by ligand binding (PDB IDs 3HLB, 3HLC, 3HLE, 3HLF, and 3HLG). Hinge motion in this two-domain enzyme is highlighted by superimposing only atoms in one of the domains (depicted in gray in this figure). The range of motion is highlighted by the rainbow colors assigned to the upper domain. The orientation of the molecule is chosen to make the range of motion evident (hinge axis is normal to the plane of the page). Each of the structures is labeled explicitly in the figure, rather than burying the information in the figure legend. Color coding the labels makes it easier to comprehend how each ligand affects the hinge motion. The structures are represented as a alpha-carbon trace rather than a cartoon ribbon because the motion is relatively small and the alpha carbon trace allows a more exact representation of the position of the atoms.

Case 5: Interfaces (≥ intermediate)
Illustration of an intermolecular interface from the PE-PPE protein complex from Mycobacterium tuberulosis (PDB ID 2G38). The left panel illustrates the complex between PE and PPE proteins as a cartoon ribbon. The two proteins are colored separately to make the interface evident. Hydrophobic side chains involved in the interface are labeled. The right panel illustrates the complementary surfaces of the interface by splitting the complex apart like a clamshell. The smaller protein is the PE protein, the larger protein is the PPE protein. Warm colors indicate strong hydrophobicity; cool colors depict weak hydrophobicity. The left and right panels are depicted on the same scale so the viewer can see how residues labeled on the left correspond to red patches in the surface on the right.
