Trypsin-inhibitory activity of ovalbumin preparations is due to ovomucoid
1Department of Clinical Chemistry, Frederiksberg Hospital, Denmark.
Abstract:
Based on the amino-acid sequence it has been proposed that ovalbumin is a proteinase inhibitor. The inhibitory activity against trypsin, chymotrypsin, pancreatic elastase, plasmin, thrombin and pancreatic kallikrein was tested, but none of these proteinases were inhibited by ovalbumin. A commercial preparation of ovalbumin contained an impurity with trypsin inhibitory activity. This impurity was probably ovomucoid.
