CDDB

CDDB provides conformational dynamics analyses of high molecular weight proteins and protein assemblies to characterize equilibrium thermal fluctuations, elastic strain energy distributions, and dynamic correlations from Electron Microscopy Data Bank (EMDB) structures.

Key Features:

• Coarse-grained computational approach: Uses a coarse-grained computational approach for efficient analysis of large macromolecular assemblies.
• Equilibrium thermal fluctuations: Computes equilibrium thermal fluctuations to identify flexible and rigid regions within proteins.
• Elastic strain energy distributions: Calculates elastic strain energy distributions to map regions associated with mechanical response and functional transitions.
• Dynamic correlations and allosteric coupling: Identifies correlations in molecular motions to detect dynamically coupled regions relevant to allosteric mechanisms.
• EMDB-based structural input: Analyzes structural data sourced from the Electron Microscopy Data Bank (EMDB).
• Focus on high molecular weight proteins and assemblies: Targets analyses specifically for high molecular weight proteins and protein assemblies.

Scientific Applications:

• Protein function and dynamics: Supports investigation of protein function through analysis of conformational dynamics.
• Protein flexibility and functional transitions: Enables studies of protein flexibility and identification of regions involved in functional transitions.
• Allosteric regulation analysis: Facilitates analysis of allosteric mechanisms by revealing dynamically coupled regions.
• Experimental design and interpretation: Provides dynamic metrics to inform experimental design and interpretation in molecular biology and biochemistry.

Methodology:

Applies a coarse-grained computational approach to EMDB structural entries to compute equilibrium thermal fluctuations, elastic strain energy distributions, and correlations in molecular motions.
