I was wondering if there any tools available for doing multiple sequence alignment for N terminal residues (say just 20 residues). I tried Blast but it gives me alignment with only one among the two subject sequences provided. I had separated the two subject sequences using a comma (is that the correct way?). I know I can manually do it, especially the identity part but for similarity, I might have to open the amino acid table. So just wanted some insights on any tool or way to do this?
