FitEM2EM—Tools for Low Resolution Study of Macromolecular Assembly and Dynamics Matching & Docking EM Maps

publication Evidence: high

Author Information

Author(s): Frankenstein Ziv, Sperling Joseph, Sperling Ruth, Eisenstein Miriam

Primary Institution: Weizmann Institute of Science

Hypothesis

The study presents new computational tools for comparing and docking low resolution structures based on shape complementarity.

Conclusion

The FitEM2EMin tool successfully matches electron microscopy structures at different resolutions and conformers, ranking correct matches at the top.

Supporting Evidence

  • FitEM2EMin can efficiently match EM maps obtained at different resolutions.
  • The tools can identify correct matches even when the structures are different conformers.
  • The matching tool ranked correct matches at the top in all tested cases.

Takeaway

This study introduces new computer tools that help scientists compare and fit images of tiny structures, even when those images are blurry.

Methodology

The study developed tools that use shape complementarity and fast Fourier transformations to match and dock low resolution structures.

Limitations

The tools may not perform well with very low resolution models or when significant structural differences exist.
