1 The carbohydrate-containing Mr 83,000 subunit was enzymatically inactive but stabilized the Mr 48,000 subunit at 37 degrees C. Trypsin, plasmin, and plasma or urinary kallikrein cleaved carboxypeptidase N into lower molecular weight active fragments, which were unstable at 37 degrees C. Cleavage of the Mr 48,000 subunit with the same enzymes increased activity and yielded fragments of Mr 29,000 or less. Carbohydrates plasminogen Homo sapiens
