Abstract
A glycoproteinase derived from the culture of Pasteurella haemolytica cleaves carbohydrate antigen markers from glycoproteins forming an integral part of plant and mammal cell membrane without general enzyme digestion of other cell protein. The glycoproteinase is separated from the media containing nutrients which induce Pasteurella haemolytica to produce the glycoproteinase released into the media.
