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.
