vanddraabe: Identification and Statistical Analysis of Conserved Waters Near Proteins
vanddraabe provides a powerful way to identify and analyze conserved
waters within crystallographic protein structures and molecular dynamics
simulation trajectories. Statistical parameters for each water cluster,
informative graphs, and a PyMOL session file to
visually explore the conserved waters and protein are returned.
Hydrophilicity is the propensity of waters to congregate near specific
protein atoms and is related to conserved waters. An informatics derived
set of hydrophilicity values are provided based on a large, high-quality
X-ray protein structure dataset.
This package is a reimplementation and expansion of the WatCH1 and PyWATER2 applications and was created to provide the following abilities:
- Perform conserved water analysis on RCSB files and molecular dynamics simulations
- Provide access to data at each step of the analysis
- Provide detailed statistical summaries for all waters being analyzed
- Ability to analyze more than 65,000 waters
- Create preformatted analysis plots
- Create PyMOL session scripts to visualize the conserved waters
- Write out an Excel workbook of initial, intermediate, and final results
- Perform protein alignment using bio3d (CRAN, website, and BitBucket), an opensource applicaiton
