these enzymes were shown to be distinct from pancreatic endopeptidases on the basis of the following : enrichment in the brush-border membrane fraction , site of hydrolysis of peptide substrates , sensitivity to specific proteinase inhibitors , and the presence of brush-border membrane-associated endopeptidase activity in mucosal cells of thirty-vella loops .
