The properties of brachyurins, proteolytic enzymes belonging to a new subfamily of chymotrypsin-like proteases, are considered. These enzymes, found in various species of crustacean, exhibit mixed substrate specificity and a marked collagenolytic activity. The enzymatic and physicochemical properties of brachyurins I and their primary and spatial structures are discussed in detail. A separate chapter is devoted to the preparations of collagenases from the hepatopancreas of king crab: their action on the damaged skin and use in medicine.
