MDContactCom

MDContactCom compares residue-residue contact fluctuations between two molecular dynamics (MD) simulation trajectories to identify and quantify differences in protein dynamic behavior under distinct conditions.

Key Features:

• Residue-Residue Contact Fluctuation Analysis: Quantifies fluctuations in interresidue contacts across different MD trajectories to reveal dynamic differences beyond static structural comparisons.
• Identification of Significant Sites: Pinpoints protein sites that show significant differences in contact fluctuations between simulations.
• Visualization Capabilities: Maps identified differences onto the protein 3D structure to visualize propagation of dynamic changes and to reveal differences not apparent from static comparisons or RMSF (Root Mean Square Fluctuation).
• Versatile Application: Applicable to a wide range of MD simulations for comparing protein dynamics under varying simulation parameters or environmental conditions.

Scientific Applications:

• Comparative MD analysis: Detects and quantifies differences in protein dynamics between two simulation conditions or setups.
• Hypothesis generation: Identifies sites with large contact fluctuation differences to guide hypotheses about the effects of simulation conditions.
• Investigation of dynamic pathways: Maps how contact changes propagate through the molecular structure to investigate potential pathways of dynamic change.

Methodology:

Systematic comparison and quantification of residue-residue contact fluctuations between two MD trajectories.
