How to submit a request to Protemot

...
Step 0

...
Click "Service" in the menu.

Step 1

...
Specify the query protein that you are interested in. You may specify the query protein either by providing a PDB ID or by uploading a file in PDB format. "substructure of interest" is an optional field. If "substructure of interest" is left blank, then the entire protein will be examined. An example for this field is as follows:

*:A, *3:A, *4,5:A, *6-9:A, *LEU:A,
where *3:A stands for the third residue in chain A and *LEU:A stands for all LEU residues in chain A.

In this page, you can adjust several settings to make the search results fit your expection. Due to the automatic extraction mechanism, Protemot contains more than 2000 templates and is still increasing along with PDB. The number in brackets is the database size. Please choose the most specific template library as possible. Another way to increase the performance of Protemot is to increase the filtering level. Our experiment results show that our filtering algorithm has very tiny effect on prediction quality.

Step 3

...
Please check your query again at this step, then click "submit" and your search task will be launched. There are three ways to get the search report. A brief report will be sent to the following e-mail address when your serach has completed. After clicking "submit", you will be directed to the progress page which includes up-to-time information of your search task. The third way is to remember your task ID and get the on-line report by the ID any time.

Step 4

...
This page shows up-to-time information of your search task which will refresh every 5 seconds by default. You can change the refresh interval as you want or check the progress of another task (remember to click "set" after entering the new refresh interval). Click "report" to see the final report of your search task when the status becomes "finished".

...
Step 5

...
The report page will list the templates similar to the substructure of the query protein which means that the query protein could have similar functional sites to these templates. You can click the template name to get more information about that template or click "show" to view the alignment results in 3D. In the 3D view, yellow portion represents the residues of the query protein which are successfully aligned; pink portion represents the template; and other portion represents the query protein.
