Assign Assign domains for your protein

If your protein is not in the list, or you can not find it by searching the table, this option is useful for you to assign domain directly on this server. Chose Assign on PDB code if your protein is in the PBD bank (July 1995). Otherwise, you should chose other options.

There are three options to assign domain on coordinates. Assign by a form is an easy way. You may paste the coordinates from a text editor to the Netscape Form window. It is better to retrieve the C-alpha records, for the assignment program needs only C-alpha coordinates. The easiest way to retrieve C-alpha records is the UNIX shell command:

    grep "^ATOM.*CA" PDB_file >C_alpha_file
Please note that it takes time to paste a big file to the Netscape Form window. Also, problems were reported by users that it did not work smoothly on their machines.

If the above option does not work on your site, please try the Assign by a Perl program. In my own experience, this is the best way to assign domain and to get the results directly, if the network transmission is not too slow between your local site and our server. However, in this case, you should have Perl installed on your machine.

The third option to assign domain for your own protein is sending us the coordiantes by E-mail. The result of domain assignment will be replied to your E-mail address. You may send the coordinates by a stand-alone mail program. However, it is better to use the built-in mail function within Netscape by clicking Assign by E-mail. Use the Attach option to attach your coordiantes file. Please fill in the Subject field with assign before sending the mail. If you can not get the reply of the results within a day, please send us a message.
