Antioxidant Activity of β-Glucan
β-Glucans extracted from barley, which mainly contains β-(1,3-1,4)-D-glucan, are used extensively as supplements and food additives due to their wide biologic activities, including a reduction in blood lipid level. In this study, the antioxidant activity of β-glucan was examined to assess potential new benefits associated with β-glucan, because oxidative stress is considered one of the primary ...
متن کاملβ-Glucan Synthase Gene Overexpression and β-Glucans Overproduction in Pleurotus ostreatus Using Promoter Swapping
Mushroom β-glucans are potent immunological stimulators in medicine, but their productivities are very low. In this study, we successfully improved its production by promoter engineering in Pleurotus ostreatus. The promoter for β-1,3-glucan synthase gene (GLS) was replaced by the promoter of glyceraldehyde-3-phosphate dehydrogenase gene of Aspergillus nidulans. The homologous recombination frag...
متن کاملAcetolactate Synthase Activity in Developing Maize
Acetolactate synthase (EC 4.1.3.18) activity was examined in maize (Zea mays L.) endosperm and embryos as a function of kernel development. When assayed using unpurified homogenates, embryo acetolactate synthase activity appeared less sensitive to inhibition by leucine + valine and by the imidazolinone herbicide imazapyr than endosperm acetolactate synthase activity. Evidence is presented to sh...
متن کاملGlycosyl moiety of the lima bean lectin.
Pronase digestion of the lima bean lectin (Phaseolus lunatus (alpha-D-GalNAc greater than alpha-D-Gal)) afforded a glycopeptide of molecular weight 1380. Amino acid and carbohydrate analysis showed the glycopeptide to contain fucose, mannose, glucosamine, and aspartic acid in the molar ratios, 0.8:4.4:1.9:1.0. Methylation analysis, Smith degradation, and sequential degradation by specific glyco...
متن کاملFluorescence polarization decay of tyrosine in lima bean trypsin inhibitor.
The fluorescence of lima bean trypsin inhibitor is due to a single tyrosine residue at position 69. The lifetime of this tyrosine fluorescence is 620 +/- 50 ps (mean +/- SD) and is little affected by addition of 0.88 M citrate, an efficient quencher of tyrosine fluorescence. The steady-state emission intensity is also only weakly reduced by the quencher. The tyrosine is thus not accessible to t...
