Induction of hepatic mitochondrial glycerophosphate dehydrogenase in rats by dehydroepiandrosterone.
Feeding the thermogenic steroid, 5-androsten-3 beta-ol-17-one (dehydroepiandrosterone, DHEA) in the diet of rats induced the synthesis of liver mitochondrial sn-glycerol 3-phosphate dehydrogenase to levels three to five times that of control rats within 7 days. The previously reported enhancement of liver cytosolic malic enzyme was confirmed. The induction of both enzymes was detectable at 0.01...
متن کاملCalcium binding to phospholipid: structural study of calcium glycerophosphate.
To consider possible interaction of the phospholipid membrane with calcium ions, crystal structures of calcium dl-alpha- and beta-glycerophosphates (alpha- and beta-CaGs, respectively) were investigated by X-ray diffraction methods. After many attempts, relatively large single crystals of beta-CaG were prepared from the aqueous solution containing HCl, while crystals of CaHPO4.2H2O were obtaine...
متن کاملHexose metabolism in pancreatic islets. Glucose-induced and Ca(2+)-dependent activation of FAD-glycerophosphate dehydrogenase.
A rise in extracellular D-glucose concentration causes in pancreatic islets a preferential stimulation of aerobic, relative to total, glycolysis. The possible participation in such a phenomenon of a glucose-induced and Ca(2+)-dependent activation of FAD-glycerophosphate dehydrogenase was investigated. In islet homogenates, the activity of the mitochondrial and Ca(2+)-responsive FAD-glycerophosp...
متن کاملCrystalline glycerophosphate dehydrogenase from rabbit muscle.
Enzymatic activity was determined in an optical test, based on the measurement of reduced DPN at 340 rnp in the Beckman spectrophotometer. The reaction was carried out in phosphate or cysteine buffer at pH 7. Synthetic dihydroxyacetone phosphate (5) with reduced DPN or racemic cr-glycerophosphate with DPN was used as substrate to measure the forward and backward reactions, respectively. The con...
متن کاملNucleotide sequence of a cDNA coding for mitochondrial fumarase from human liver.
The nucleotide sequence of a 1.46 kb cDNA, selected from a human liver library by the expression of fumarase antigenic determinants, was determined using the dideoxy chain termination method. The cDNA contained an open reading frame extending from the extreme 5'-base and coding for a protein with 468 amino acids. This protein, with the exception of an N-terminal methionine, was identified as mi...
