WebPepsin breaks down proteins and peptides. It was first recognized in 1836 by T. Schwann and isolated in crystal form in 1930 by J. Northrop. Pepsin is an endopeptidase, that is, an enzyme that splits the central peptide bonds in protein and peptide molecules, except keratins and other scleroproteins, to form simpler peptides and free amino acids. WebPepsin is inhibited by several phenylalanine-containing peptides. Preferential cleavage: hydrophobic and aromatic residues in P1 and P1′ postitions.
