Dietary regulation of 6-phosphogluconate dehydrogenase synthesis.
The relative rates of synthesis and degradation for rat liver 6-phosphogluconate dehydrogenase have been determined in animals maintained at several dietary states. Relative rates of synthesis were determined by pulse-labeling the enzyme either in live rats and determining the radioactivity in the purified enzyme or in whole cell suspensions of hepatocytes followed by precipitation of the enzym...
متن کاملGeobacillus stearothermophilus 6-phosphogluconate dehydrogenase complexed with 6-phosphogluconate
Two crystal structures of recombinant Geobacillus stearothermophilus 6-phosphogluconate dehydrogenase (Gs6PDH) in complex with the substrate 6-phosphogluconate have been determined at medium resolution. Gs6PDH shares significant sequence identity and structural similarity with the enzymes from Lactococcus lactis, sheep liver and the protozoan parasite Trypanosoma brucei, for which a range of st...
متن کامل6-Phosphogluconate dehydrogenase from leuconostoc mesenteroides.
The pathways for degradation of 6-phosphogluconate have been rather clearly defined for several organisms, the most notable of which are yeast (Horecker, 1953), Escherichia coli (Cohen, 1951), Pseudomonas saccharophila (Entner and Doudoroff, 1952; MacGee and Doudoroff, 1954), and Pseudomonas fluorescens (Kovachevich and Wood, 1954). The enzymes from yeast and E. coli appear to be similar, if no...
متن کاملMicrofluorometry of glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase in red cells.
A simple microfluorometric method isdescribed for measu ring gIucose-6-phosphate dehyd rogenase (GPD) and 6-phosphogluconate dehydrogenase (PGD) activities in human erythrocytes. Only 50 ,J of whole blood is required. The cells are lysed with digitonin and the rate of NADPH generated in the enzymatic reactions is followed kinetically with a recording fluoromete. GPD activity is measured by subt...
متن کاملIn Silico Analysis of Arabidopsis thaliana Peroxisomal 6-Phosphogluconate Dehydrogenase
NADPH, whose regeneration is critical for reductive biosynthesis and detoxification pathways, is an essential component in cell redox homeostasis. Peroxisomes are subcellular organelles with a complex biochemical machinery involved in signaling and stress processes by molecules such as hydrogen peroxide (H2O2) and nitric oxide (NO). NADPH is required by several peroxisomal enzymes involved in β...
