WebFR3D Search Page

This page is newly constructed in September 2024. It works reasonably well, but has not been extensively tested yet. If you find a problem, please send an email to Craig Zirbel at zirbel@bgsu.edu. Copy the URL of the result if one is produced, that will help to diagnose the problem.

1. Describe the motif you are looking for, using (a), (b), or both.
a. For a purely symbolic search, specify the number of positions in the motif and then add symbolic constraints below.
b. If you have a set of nucleotides that form the motif, and you want to search for other instances according to the geometry of the motif, fill in their unit IDs, separated by commas:
and set the maximum geometric discrepancy from the query nucleotides:
2. To add symbolic constraints, click the button below and then fill in interactions like cWW or stack in the yellow boxes, and chain continuity constraints in the blue boxes.
3. What structures from the Protein Data Bank should be searched? Use (a), (b), or both.
a. List individual structures (like 6ZMI) or chains (like 6ZMI|1|L5), separated by commas:
b. Specify an or by typing the release number and the resolution cutoff
4. Give your search a description (0 to 150 characters):
5. When you are ready to launch the search, click the Search button:
