3DEM Loupe

3DEM Loupe performs normal mode analysis (NMA) on electron microscopy (EM) volumes to investigate potential conformational dynamics of macromolecular structures within the 3–20 Å resolution range.

Key Features:

• Normal Mode Analysis of EM Volumes: Applies normal mode analysis (NMA) to electron microscopy density maps to explore potential conformational changes in macromolecular complexes.
• Three-Dimensional Dynamic Representation: Generates animations and movies representing predicted structural motions and conformational transitions derived from NMA results.
• Macromolecular Motion Exploration: Enables analysis of structural dynamics associated with biological processes such as ligand binding, protein–protein interactions, and channel opening.

Scientific Applications:

• Macromolecular Dynamics Analysis: Investigates conformational variability and intrinsic motions of macromolecular complexes derived from electron microscopy reconstructions.
• Structural Biology Studies: Examines dynamic structural features of proteins and macromolecular assemblies that are not captured in static EM density maps.
• Functional Mechanism Investigation: Identifies structural movements associated with biological functions, including ligand-induced conformational changes and protein interaction dynamics.

Methodology:

3DEM Loupe applies normal mode analysis (NMA) to electron microscopy density volumes to compute and visualize potential conformational motions of macromolecular structures.
