+EM Navigator
3D electron microscopy data browser
![](../emnavi/img/about_emn.jpg)
URL: https://pdbjlvh1.pdbj.org/emnavi/.
- EM Navigator is a browser for 3D electron microscopy (3D-EM) data of biological molecules and assemblies.
- It provides EMDB-PDB cross-search, statistical information, and links to similar structures.
- You can easily check the latest EM structural data and structural papers.

- The table can be sorted. Click the column header to be sorted. (second click to reverse, [Shift]+click for multi-column sort)
- To show the bar graph in table mode, point the column/row header by mouse courser.
- To search the correspoinding data, click the cell of value.

- Yorodumi is a browser for structure data from EMDB, PDB, SASBDB, etc.
- This page is also the successor to EM Navigator detail page, and also detail information page/front-end page for Omokage search.
- The word "yorodu" (or yorozu) is an old Japanese word meaning "ten thousand". "mi" (miru) is to see.

+Omokage search
Search structure by SHAPE
![](../emnavi/img/about_omosearch.jpg)
URL: https://pdbj.org/omokage/
- "Omokage search" is a shape similarity search service for 3D structures of macromolecules. By comparing global shapes, and ignoring details, similar-shaped structures are searched.
- The search is performed ageinst >200,000 structure data, which consists of EMDB map data, PDB coordinates (deposited units (asymmetric units, usually), PDB biological units, and SASBDB mdoels).
- For the search query, you can use either a data in the PDB/EMDB/SASBDB or your original model.
- Supported formats are PDB (atomic model, SAXS bead model, etc.) and CCP4/MRC map (3D density map).
- Shape comparison is performed by iDR profile method, which uses 1D-distance profiles of super-simplified models generated by vector quantizaion in Situs package.
