Advanced Protein Statistics


You can produce a short-form report with a number of statistics for one or more protein sequences at a time.

The following parameters are available:

  • Individual statistics layout. If more than one sequence is selected, a separate short-form report is generated for each sequence.
  • Comparative statistics layout. If more than one sequence is selected, a short-form report with comparisons between the sequences is generated.
  • Background distribution of amino acids. If this box is ticked, an extra column with amino acid distribution of the chosen species is included in the table output. (The distributions are calculated from UniProt www.uniprot.org version 6.0, dated September 13 2005.)


The report includes

  • Basic protein statistics:
    • Sequence type
    • Length
    • Organism
    • Locus
    • Description
    • Modification date
    • Weight
    • Isoelectric point
    • Aliphatic index

  • Half-life
  • Extinction coefficient
  • Counts of Atoms
  • Frequency of Atoms
  • Count of hydrophobic and hydrophilic residues
  • Frequencies of hydrophobic and hydrophilic residues
  • Count of charged residues
  • Frequencies of charged residues
  • Amino acid distribution
  • Histogram of amino acid distribution

The report can be saved, printed or exported to PDF.
