A pigeon pancreas microsomal system supplemented with microsomal supernatant fluid or pH 5 enzyme incorporates radioactive amino acids into purified amylase. Several parameters of the incorporation system are presented. TrypCc digestion of the isolated radioactive amylase shows that the amino acids are incorporated into peptide linkage within the protein, as in amylase synthesized in viva. The ...

The production of extracellular amylase by Bacillus subtilis has been studied in solid-state fermentation (SSF). In a sequential order, various process parameters were optimized for maximum amylase production. The tested process parameters were different solid substrates such as banana husk (BH), water melon husk (WMH), lentil bran (LB), wheat bran (WB), melon husk (MH) and maize oil cake (MOC)...

Wheat starch degradation requires the synergistic action of different amylolytic enzymes. Our spatio-temporal study of wheat α-amylases throughout grain development shows that AMY3 is the most abundant isoform compared with the other known α-amylases. Endosperm-specific over-expression of AMY3 resulted in an increase of total α-amylase activity in harvested grains. Unexpectedly, increased activ...

The flux of alpha-amylase (1,4-alpha-D-glucan glucanohydrolase; EC 3.2.1.1) across the basolateral membrane of the acinar cell was measured in the cell-to-bath direction using the whole rabbit pancreas in organ culture. This in vitro preparation is polarized so that apical and basolateral secretions can be collected separately. The unstimulated amylase flux from cell to bath was substantial at ...

in this study, the effects of dietary egg lecithin on digestive enzymes and body biochemical composition of juveniles mesopotamichthys sharpeyi was evaluated. four experimental diets including control diet (with 0% egg lecithin) and three diets containing 2%, 4% and 6% egg lecithin were used. at the end of the experiment, digestive enzymes activity (lipase, amylase and alkaline phosphatase) and...

The antioxidant properties and effect of essential oil of black pepper (Piper guineense) seeds on α -amylase, α -glucosidase (key enzymes linked to type-2 diabetes), and angiotensin-I converting enzyme (ACE) (key enzyme linked to hypertension) were assessed. The essential oil was obtained by hydrodistillation and dried with anhydrous Na2SO4, and the phenolic content, radical [1,1-diphenyl-2 pic...

BACKGROUND Pancreatic fistula is still one of the most serious and potential complications after D2-D3 distal and total gastrectomy (4% to 6%). Despite their importance, pancreatic fistulas still have not been uniformly defined. Amylase concentration of the drainage fluid after surgery for gastric cancer can be considered as a predictive factor of the presence of pancreatic fistula. METHODS F...
