Ligplot 〈HIGH-QUALITY〉

Figure 1 (conceptual): A LIGPLOT of the HIV-1 protease inhibitor indinavir. Hydrogen bonds are green dashed lines; hydrophobic contacts are red arcs; the ligand is in thick black bonds.

LigPlot represents a critical intersection between computational geometry and visual communication in biology. By translating complex 3D coordinate data into standardized 2D interaction maps, it democratizes access to structural insights, allowing chemists and biologists to intuitively grasp the mechanics of molecular recognition. While newer tools with 3D-hybrid views exist, the clarity and simplicity of the LigPlot schematic ensure its continued relevance as a staple tool in the structural biologist's arsenal. ligplot

LIGPLOT operates on a single input: a Protein Data Bank (PDB) file containing the coordinates of a protein-ligand complex. Figure 1 (conceptual): A LIGPLOT of the HIV-1
