ProDy is a free and open-source Python package for analyzing protein structural dynamics. It allows for quantitative analysis of heterogeneous experimental structural datasets and comparison with theoretically predicted conformational dynamics. It is designed and developed by Ahmet Bakan in Bahar lab at the University of Pittsburgh.
The following are some of the main features:
Examination and analysis of structural variability observed in experiments:
- Fast and flexible parsing of PDB and DCD files
- Powerful and customizable atom selections and contact identification
- Matching, superposing, and comparing multiple structures/chains
- PCA of X-ray structures, NMR models and mixed structural datasets from Blast search
Prediction and analysis of protein dynamics using theory and simulation:
- Normal Mode Analysis using the Anisotropic network model (ANM)
- Gaussian network model (GNM) analysis
- Distance and property dependent force constant functions
- Essential dynamics analysis (EDA) of MD snapshots
- Comparative analysis and visualization of dynamics
