The current study deals with a digestive α-amylase in the larvae of Pieris brassicae L. through purification, enzymatic characterization, gene expression, and in vivo effect of a specific inhibitor, Acarbose. Although α-amylase activity was the highest in the whole gut homogenate of larvae but compartmentalization of amylolytic activity showed an equal activity in posterior midgut (PM) and ante...

The amylolytic and related enzymes have been classified into the families of glycoside hydrolases (GHs). At present there are almost one hundred GH families. The main α-amylase family is the family GH-13 that forms the clan GH-H together with the families GH-70 and GH-77. β-Amylases and glucoamylases have their own families GH-14 and GH15, respectively. Some amylolytic enzymes are grouped also ...

Abstract Despite the richness and biodiversity of invertebrates algae in Mediterranean Sea, these organisms are still poorly studied. The objective our research is discovery bioactive lead compounds from Sea sponge Hemimycale Collumella (HC). HC (189.0 g) was collected Mdiq costs on extracted with methanol to yield (10 which then subjected fractionation. A bio-guided protocol applied through ev...

Before this study, there had been no research evaluating the relationship between a lysosomal exoglycosidase profile and secretory function in the salivary glands of rats with streptozotocin- (STZ-) induced type 1 diabetes. In our work, rats were divided into 4 groups of 8 animals each: control groups (C2, C4) and diabetic groups (STZ2, STZ4). The secretory function of salivary glands-nonstimul...

BACKGROUND Low serum amylase is likely to be associated with obesity and metabolic abnormalities, which are often accompanied by impaired insulin action. However, it is unclear whether low serum amylase is associated with impaired insulin action in clinical settings. Therefore, we investigated the associations of low serum amylase with plasma insulin levels, and obesity-related parameters, incl...

Hydrogen gas (H2) is considered as a signaling molecule and plays multiple roles in plant growth. However, the effect of H2 on postharvest physiology lily scales during storage has not been reported. In this study, regulatory hydrogen-rich water (HRW, donor, concentration 0.45 mM for 100% HRW) status, ion balance, nutrients Lanzhou (Lilium davidii var. unicolor) were investigated. The soaked HR...

Wheat α-amylase, a multi-domain protein with immense industrial applications, belongs to α+β class of proteins with native molecular mass of 32 kDa. In the present study, the pathways leading to denaturation and the relevant unfolded states of this multi-domain, robust enzyme from wheat were discerned under the influence of temperature, pH and chemical denaturants. The structural and functional...
