Please be advised that we have recently moved our server to a new location. We tried our best to fully test all functions on the website, but if something does not work for you please let us know.

PDB database is updated every Wednesday; Pfam database is updated monthly.

1).   Please paste one amino-acid sequence in fasta format (please sign in to submit more sequences and to store a list of your results)
2).   Sequences longer than 1000 aa should be split into (putative) domains.
3).   Examples of ffas server input and resulting ouput.

    .   10    .   20    .   30    .   40    .   50    .   60    .   70    .   80    .   90    .  100

4).   Option: upload psi-blast result in text format to calculate the profile (otherwise psi-blast is run on the server)
 (can only be used for a single query sequence which provided in the text field above)

5).   Option: upload multiple sequence alignment in fasta format instead of submiting a single query sequence.

6).   Option: instead of submitting one protein sequence, please login to upload a protein sequence file in fasta format(<=100 sequences). Providing an email at login is required.

(We are limiting the bulk submission because of abuse. If you need to run entire genomes, please contact us )

7).   Option: check this box to include additional metagenomic data in the database used to calculate protein profile.
