Introduction

This script detects waters molecules within a specified distance from the ligand.
Detected water molecules are shown as spheres.
Distances between water molecules and O or N atoms of ligand (potential H-bonds) are shown by dotted lines.
An output file containing a list of distance between waters and ligand atoms and the number of interactions is written in the main PyMol folder.


Usage

waters [ligand name, distance]


Required Arguments

  • ligand name = the ligand residue name
  • distance = max distance in Angstroms


Examples

example #1 on PDB structure (1C0L) 

PyMOL>waters FAD, 2.8

Output in GUI of PyMol:

Total number of water molecules at 2.8 A from ligand FAD: 3 Number of water molecules that interact with ligand: 3 Number of ..→
