Characteristics of glutathione biosynthesis by freshly isolated rat kidney cells.
Suspensions of freshly isolated rat kidney cells were used to study glutathione biosynthesis and utilization for amino acid translocation. Incubation of cells isolated from diethylmaleate-perfused kidneys in the presence of glutamate, glycine, and cystine led to replenishment of cellular glutathione and to accumulation of glutathione disulfides in the medium. Cystine could be replaced by cystei...
متن کاملGlutathione reductase is inhibited by acetaminophen-glutathione conjugate in vitro.
The aim of the present work was to investigate a new mechanism likely contributing to the toxic action of acetaminophen, especially to explore the possible inhibition of glutathione reductase through an acetaminophen-glutathione conjugate (APAP-SG). APAP-SG conjugate was synthesized by organic synthesis and purified by column chromatography. The inhibitory effect of the conjugate on two types o...
متن کاملHepatic glutathione and glutathione S-conjugate transport mechanisms.
Glutathione (GSH) plays a critical role in many cellular processes, including the metabolism and detoxification of oxidants, metals, and other reactive electrophilic compounds of both endogenous and exogenous origin. Because the liver is a major site of GSH and glutathione S-conjugate biosynthesis and export, significant effort has been devoted to characterizing liver cell sinusoidal and canali...
متن کاملGlutathione-s-transferase activity and metabolism of glutathione conjugates by rhizosphere bacteria.
Glutathione-S-transferase (GST) activity was determined in 36 species of rhizosphere bacteria with the substrate 1-chloro-2,4-dinitrobenzene (CDNB) and in 18 strains with the herbicide alachlor. Highest levels of CDNB-GST activity (60 to 222 nmol (middot) h(sup-1) (middot) mg(sup-1)) were found in gram-negative bacteria: Enterobacter cloacae, Citrobacter diversus, Klebsiella planticola, Pseudom...
متن کاملHepatobiliary transport of glutathione and glutathione conjugate in rats with hereditary hyperbilirubinemia.
TR- mutant rats have an autosomal recessive mutation that is expressed as a severely impaired hepatobiliary secretion of organic anions like bilirubin-(di)glucuronide and dibromosulphthalein (DBSP). In this paper, the hepatobiliary transport of glutathione and a glutathione conjugate was studied in normal Wistar rats and TR- rats. It was shown that glutathione is virtually absent from the bile ...
