Selenium administration resulted in a marked decrease in the activity levels of the liver succinate dehydrogenase, malate dehydrogenase, and lactate dehydrogenase while pyruvate dehydrogenase increased significantly (P<0.001) in the wistar rat. The degree of decrease of these enzymes was significantly less (P<0.001) when rats were treated with curcumin, a natural constituent Curcuma longa. Curc...
The aim of this research was to develop a suitable method of succinate dehydrogenase activity assay in situ for different industrial yeast strains. For this purpose different compounds: EDTA, Triton X-100, sodium deoxycholate, digitonin, nystatin and beta-mercaptoethanol were used. The permeabilization process was controlled microscopically by primuline staining. Enzyme assay was conducted in w...
Activities of succinate oxidase, fumarate reductase (FR) and succinate dehydrogenase (SDH) under a set of defined conditions were determined in the mitochondrial isolate from Setaria digitata, the filarial parasite from the cattle Bos indicus. Presence of only two activities namely SDH and succinate--UQ reductase of the succinate oxidase system could be detected in S. digitata. In the absence o...
Staphylococcus epidermidis has become a major health hazard. It is necessary to study its metabolism and hopefully uncover therapeutic targets. Cultivating S. epidermidis at increasing oxygen concentration [O2] enhanced growth, while inhibiting biofilm formation. Respiratory oxidoreductases were differentially expressed, probably to prevent reactive oxygen species formation. Under aerobiosis, S...
A deficiency of succinate dehydrogenase is a rare cause of mitochondrial encephalomyopathy. Three patients, 2 sisters and 1 boy from an unrelated family, presented with symptoms and magnetic resonance imaging signs of leukoencephalopathy. Localized proton magnetic resonance spectroscopy indicated a prominent singlet at 2.40ppm in cerebral and cerebellar white matter not present in gray matter o...
A partial genomic clone of the flavoprotein subunit of the mitochondrial enzyme, succinate dehydrogenase (EC 1.3.99.1) from Saccharomyces cerevisiae has been isolated. The partial clone was used to construct, by targeted gene disruption, a yeast mutant with a defective flavoprotein subunit gene. Submitochondrial membranes from the mutant are defective in activities requiring a functional succin...
As a part of the investigation on the senile changes, histochemical findings of some enzyme activities in the resting and regenerating liver have been compared between senile and young adult rats. In the resting senile liver, succinate dehydr.ogenase, cytochrome oxidase and glucose-6-phosphataseexhibited a tendency to decrease in activity, especially in the central and mid-zonal areas of the lo...
