Silicon (Si) can protect some plants from biotic and abiotic stresses. In this research, effects of three exogenous Si levels (0, 0.85 and 1.7 mM) on growth, lipid peroxidation, lipoxygenase activity, proline content, H2O2 accumulation, and activity of non-enzymatic and enzymatic antioxidants (catalase and ascorbate peroxidase) under powdery mildew disease stress by Sphaerotheca fuliginea on pu...
Between 1930 and 1975 biochemical and structural analysis of enzymes led to a clear set of ideas that might form a basis for detailed understanding of enzyme action. Further development required energetic and thermodynamic analysis of enzymes in an aqueous medium, beyond the computational power then available. Structural enzymology advanced in other directions, but the fundamental questions of ...
Background and Objectives: Bioactive peptides have different health benefits and functional characteristics and are produced by enzymatic hydrolysis, microbial fermentation and chemical synthesis methods. The purpose of this study was to optimize the enzymatic hydrolysis conditions of fenugreek seed protein with alcalase and to evaluate the antioxidant properties of the resulting peptides. Mate...
Nowadays, the use of a wide range of medicinal herbs such as saffron and its aromatic compounds is increasingly being regarded as natural sources of antioxidant properties. In addition to saffron stigma, saffron petal is a rich herbal source of antioxidant compounds. The present study was conducted in a completely randomized design with three replications to study some of the enzymatic and non-...
The knowledge of the digestive system of bullfrogs is an important step for the determination of their nutritional requirements throughout growth phases. With the objective of evaluating the enzymatic activity of lipase in the intestinal content of bullfrogs (Rana catesbeiana Shaw, 1802), 100 animals with median weight of 3.6 g were distributed in stalls under controlled temperature and photope...
the elm leaf beetle xanthogaleruca luteola müller (coleoptera: chrysomelidae), is a serious pest of elm (ulmus spp.) throughout iran. in the present study, lethal and sublethal effects of neem, achook® containing 0.03% azadirachtin, were assessed on mortality, growth, larval weight and feeding deterrence as well as enzymatic and non-enzymatic activities of third instar larvae of the elm leaf be...
Background: Human Cu/Zn superoxide dismutase (hSOD1) is an antioxidant enzyme with potential as a therapeutic agent. However, heterologous expression of hSOD1 has remained an issue due to Cu2+ insufficiency at protein active site, leading to low solubility and enzymatic activity.Objectives:The effect of co-expressed human copper chaperone (hCCS) to enhance the solubility and enzymatic act...
