Although there is little doubt that more than one proteolytic enzyme occurs in plasma, plasmin (fibrinolysin) is the only such enzyme which has been definitely identified. Astrup and Permin,12 on the basis of differences in susceptibility to activation by streptokinase and fibrinokinase, have suggested that there are two precursors of fibrinolytic enzymes in human blood. They have designated th...

A qualitative and quantitative characterization of the proteolytic activity of a number of rat liver cell fractions was undertaken using lY51-labeled hemoglobin as substrate. The results indicated that proteolytic activity in rat liver was of two major types. The first was characteristic of activity accounted for by the endopeptidase cathepsin I). It was sensitive to the inhibitor pepstatin, an...

Proteolytic degradation of the extracellular matrix (ECM) is critical in cancer invasion, and recent work suggests that heterogeneous cancer populations cooperate in this process. Despite the importance of cell heterogeneity, conventional proteolytic assays measure average activity, requiring thousands of cells and providing limited information about heterogeneity and dynamics. Here, we develop...

due to the importance of adult artemia in aquaculture, information regarding the digestive enzyme activities variation with inexpensive diets has great importance in artemia at different life stages. in this study, the effect of different inexpensive diets on digestive enzyme activities, including trypsin, amylse and lipase of artemia urmiana was investigated in different life stages. the exper...

Growth rate is dependent upon adequate provision of amino acids especially in newly-hatched fish which experience very high growth rate. The replacement of a fraction of protein content by partially hydrolyzed (pre-digested) proteins was carried out and the digestive capacities and performances of larval/juvenile spotted wolffish (Anarhichas minor) were measured. The goal of this study was to v...

The effects of 7- and 14-day exposure to water-dissolved Cu at sublethal concentrations 0.01 0.1 mg/L subsequent increase in water temperature a rate 8°C/h on intestinal proteolytic activity (PA) amylolytic (AA), as well brain acetylcholinesterase (AChE) water-soluble protein (WSP) content juvenile roach Rutilus rutilus have been vivo studied. Additionally, the values upper were determined by c...

Mucoromycotina are often considered mainly in pathogenic context but their biology remains understudied. We describe the genomes of six fungi representing distant saprotrophic lineages within subphylum (i.e., Umbelopsidales and Mucorales). selected two Umbelopsis isolates from soil U. isabellina, vinacea ), soil-derived Mucor M. circinatus, plumbeus Mucorales representatives with extended prote...
