Institute of Fisheries Technology Research, Tromsø, Norway.

1. A pancreatic elastase from Atlantic cod (Gadus morhua) has been purified and characterized. 2. The enzyme is a very basic protein with an approximate mol. wt of 28,000. 3. The cod elastase has higher elastin specificity than porcine elastase, and it is inhibited by soybean trypsin inhibitor, which has no effect on porcine elastase. 4. The cod elastase expresses a higher turnover number (kcat) and catalytic efficiency (kcat/Km) than porcine elastase, but it is less thermostable.

UI	MeSH Term	Description	Entries
D007700	Kinetics	The rate dynamics in chemical or physical systems.
D008970	Molecular Weight	The sum of the weight of all the atoms in a molecule.	Molecular Weights,Weight, Molecular,Weights, Molecular
D010179	Pancreas	A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
D010196	Pancreatic Elastase	A protease of broad specificity, obtained from dried pancreas. Molecular weight is approximately 25,000. The enzyme breaks down elastin, the specific protein of elastic fibers, and digests other proteins such as fibrin, hemoglobin, and albumin. EC 3.4.21.36.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
