This is the pepsin primary sequence of the amino acid residues within the protein (1pso):




glapva
- describe details of the primary sequence (eg number of amino acid residues).
- label and describe carboxy and amino termini.
- label extra features besides the ends, two other regions of the protein and describe their function using simple language.
- describe catalytic sequences or other important amino acid residues.
- describe a feature of amino acid chemistry (eg. signal peptide, which is composed of hydrophobic amino acids or chemistry of an important amino acid residue).
