Catalytic efficiencies of alkaline proteinases from microorganisms.
Catalytic efficiencies of proteinase K and mesentericopeptidase were determined using series of peptide-4-nitroanilide substrates and compared with those of subtilisin DY, savinase and esperase. For each enzyme the subsites S1-S4 were characterized. The data for the enzyme specificities were related to our high resolution X-ray models of the five enzymes and their complexes with peptides. The c...
متن کاملDigestive proteinases from marine organisms and their applications
Fish viscera have wide biotechnological potential as a source of digestive enzymes, especially proteinases. The biological diversity of fish species provides a wide array of enzymes with unique properties. Fish digestive proteolytic enzymes most commonly found include pepsin and trypsin. Those enzymes from fish viscera may have the advantages for the applications in the food industry since thei...
متن کاملPests, Plagues, and Patents
The paper investigates the interaction between dynamic forms of incentive mechanisms (patent systems) and dynamic forms of problems (adaptations of pests and pathogens). Since biological problems recur, the design of the incentive mechanism must take into consideration: a) the need for investments into R&D that take into account the impermanence of the solution concepts; and b) the impact of th...
متن کاملPurification and characterisation of cysteine proteinases from human osteoclastomas.
The process of normal bone remodeling requires the continual resorption and replacement of bone mineral and bone matrix proteins. Excessive bone resorption is a feature of a number of pathological conditions. These include osteoporosis, rheumatoid arthritis and Paget's disease [l]. Bone resorption is accomplished by the osteoclast. Osteoclasts attached to bone are highly polarised cells [2]. Th...
