All databases were updated in June 2014. 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.(new)


6).   Option: instead of submitting one protein sequence, please login to upload a protein sequence file in fasta format.
(providing an email at login is required. creating a separated account for this job is highly recommended)


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