Visual representations of peptide sequences

Abstract

A system for visually representing peptide sequences includes a memory configured to store instructions and a processor to execute the instructions to perform operations. The operations include receiving data representing a peptide sequence. The data includes an index representing a position for each amino acid in the peptide sequence. The operations further include categorizing each amino acid in the peptide sequence and assigning each amino acid a value associated with the category. The operations additionally include determining relationship groups, each group including two amino acids in the peptide sequence, based upon a geometrical structure of the peptide sequence. The operations also include filtering the relationship groups to remove groups based upon the category of at least one of the two amino acids that make up the group; and producing a visual representation that includes a representation of each amino acid of the filtered relationship groups.
