the property of brain endopeptidases of attacking small biologically active polypeptides but not denatured proteins led us to compare them with pancreatic proteolytic enzymes with respect to hydrolysis of a synthetic peptide derived from bradykinin ( gly-gly-gly-arg-bradykinin ) , free , bound to affi-gel 10 , or bound to succinylated polylysine of 3,000 and 180,000 daltons , respectively .
