Family generator

In this page you can create a family of antimicrobial peptides featuring user-selected properties.
Please take a look at the Frequently Asked Questions (FAQ) and the tutorial.

Note: To know more about each field simply hover your mouse over it. in some fields the following options are available: y="yes; n="no"; or i=ignored.


  Calculation label (mandatory)Choose a name for the experiment to run
  Username (mandatory)Choose a key that will be used to group your experiments
    Email notification (mandatory)  Send by mail information about the calculation label and the start and finishing of the experiment
  Append User peptidesSpecify one or more user customized sequences to include in the experiments (separated by commas)
      Create the family of a specific peptide  

Optional selection criteria (a run with unspecified criteria might require long calculation times):
Peptide nameSelect peptide by its common name (e.g. aurein)
Sequence pattern                      Select peptide by a pattern (e.g. KKV will find all peptides containing such pattern, GL-DIVKKVVGA-GS- with allow - positions to be any residue, but note that last - will need to be dropped to include shorter peptides than that length).
Please remember that if you set "work in simplified aa space" to "DSSP" you need to pass your sequence in DSSP field instead
Target OrganismSelect by the activity towards one specific organism (e.g. baumannii). In order to avoid certain organisms you can add "n_" in front of the name (i.e. "n_coccus" will select all species but coccus). To get peptides against any organism type "X"
  Activity (µM)  Maximum µM concentration for activity against the specified Organism, type X for peptides with any defined activity value
Activity test  Type of activity test experimentally used (e.g. MIC, MAC, LD50, IC50, IC100, GI50, HC10, EC50, EC100, HD50, HC50, LC50, MHC, MBC...)

  Align method:Choose method to perform the alignment between peptides.
In simple the number of amino-acid type is reduced to 9: hydrophobic (A, V, I, L, M represented by A), negative (D, E represented by D), positive (K, R by K), aromatic (W, Y, H, F by F), polar (S, T, N, Q by S), Gly, Pro, Cys and modified amino acids (by Ⓜ)).
In DSSP its syntax for 8 types of secondary structure is used (H: alpha-helix; B: isolated beta-bridge; E: extended strand; G: 3/10 helix; I: pi helix; T: Turn; S: Bend and Blank; C: Loop).
In Substitution matrix mode, matrices are used to score alignments between divergent sequences.
Simple DSSP Substitution matrix
Choose matrix to be used for alignment (i.e. Blosum45, PAM250, Unitary scoring matrix...)
       Minimum % of similarity Choose minimum percentage of similarity with the father to consider a peptide to be a member of a family
       Threshold percentage to group families Group families with a percentage of members in common superior to this value

  Simplify aminoacids:Transform non-standard amino acids to their most similar standard one
y n
        Experimentally validated:Restrict the search to experimentally validated entries
i y n
  Include only peptides with data about:Only consider as experimentally validated those peptides with defined Target Organism and/or activity values

  Run SeqLogo:Enable or disable the generation of sequence logos with WebLogo/SeqLogo software
y n
         Generate additional graphical analysis:Generate additional graphics for each family (requires longer calculation times)
y n
Results will be viewable in the DOWNLOAD RESULTS section. You can extract meaningful information from the experiment using FAMILY ANALYZER tool too.
