Cloning, expression, purification and assay of sorbitol dehydrogenase from "Feicheng" peach fruit (Prunus persica)
Provedor de dados: 52
Autores: Sun,Zhen; Ma,Chunmei; Zhou,Jie; Zhu,Shuhua.
A gene encoding NAD+-dependent sorbitol dehydrogenase (SDH) in peach fruit was cloned and expressed in Escherichia coli. Recombinant SDH protein with 6×His-tagged was localized exclusively in the cytoplasmic soluble fraction of E. coli when the strains were grown for 4-5 h at 37 ºC. Highly pure protein was isolated by Ni2+-resin chromatography with 150 mM imidazole in 50 mM Tris, pH 8.0, by elution. In order to ensure that the recombinant SDH could be used for further study, the fluorescence and ultraviolet spectrum of the recombinant SDH were detected. Recombinant SDH was confirmed to be capable of oxidizing sorbitol by enzymatic activity assay. The activity of the recombinant SDH was 2.73 U mg-1min-1, which was similar with that directly extracted from...

Effect of an aqueous extract of Scoparia dulcis on blood glucose, plasma insulin and some polyol pathway enzymes in experimental rat diabetes
Provedor de dados: 56
Autores: Latha,M.; Pari,L.
The effects of an aqueous extract of the plant Scoparia dulcis (200 mg/kg) on the polyol pathway and lipid peroxidation were examined in the liver of streptozotocin adult diabetic male albino Wistar rats. The diabetic control rats (N = 6) presented a significant increase in blood glucose, sorbitol dehydrogenase, glycosylated hemoglobin and lipid peroxidation markers such as thiobarbituric acid reactive substances (TBARS) and hydroperoxides, and a significant decrease in plasma insulin and antioxidant enzymes such as glutathione peroxidase (GPx), glutathione-S-transferase (GST) and reduced glutathione (GSH) compared to normal rats (N = 6). Scoparia dulcis plant extract (SPEt, 200 mg kg-1 day-1) and glibenclamide (600 µg kg-1 day-1), a reference drug, were...
