exopeptidases

• exopeptidases work to hydrolyse peptide bonds at the ends of proteins molecules
• they remove single amino acids from proteins
• dipeptidases are exopeptidases that work specifically on dipeptides. they separate the two amino acids that make up a dipeptide by hydrolysing the peptide bond between them
• dipeptidases are often located in the cell-surface membrane of epithelial cells in the small intestine
