MovieMaker

MovieMaker generates short (~10-second) downloadable animations that illustrate protein motions and interactions to visualize dynamic structural processes.

Key Features:

• Input Flexibility: Accepts Protein Data Bank (PDB) files or PDB accession numbers as input.
• Animation Types: Produces animations including simple rotation; morphing between two end-state conformers; short-scale picosecond vibrations; ligand docking; protein oligomerization; mid-scale nanosecond (ensemble) motions; and protein folding/unfolding.
• Output Format: Generates short, downloadable animations suitable for illustrative and analytical purposes.

Scientific Applications:

• Ligand docking visualization: Illustrates ligand binding events and conformational changes associated with docking.
• Protein folding and unfolding: Depicts folding pathways and large-scale conformational transitions.
• Oligomerization analysis: Visualizes assembly and inter-subunit rearrangements during oligomer formation.
• Timescale-specific motion depiction: Represents short-scale picosecond vibrations and mid-scale nanosecond ensemble motions for mechanistic interpretation.
• Conformer comparison: Morphs between end-state conformers and provides rotational views to compare structural differences.

Methodology:

Employs a superpositioning algorithm combined with Cartesian coordinate interpolation to calculate intermediate structures automatically and does not perform molecular dynamics calculations.
