Color Align Properties


Color Align Properties accepts a group of aligned sequences (in FASTA or GDE format) and colors the alignment. The program examines each residue and compares it to the other residues in the same column. Residues that are identical or similar among the sequences are given a colored background. The color is chosen according to the biochemical properties of the residue. You can specify the percentage of residues that must be identical and similar for the coloring to be applied. Use Color Align Properties to highlight protein regions with conserved biochemical properties.

Paste the aligned sequences in FASTA or GDE format into the text area below. Input limit is 200000 characters.





  • Show residues per line.
  • Percentage of sequences that must agree for identity or similarity coloring to be added:
  • Used colored .
Enter the starting positions of the sequences separated by commas (to alter residue numbering). An example entry is: 0, 200, 0, -1. If no numbers are given, the default starting position of 0 is used for each sequence.
