sulfamyl and carbamyl
groups in the same molecule was achieved in good yield.
The effects of 204 atm pressure on the stimulation of [[S.sup.35]]GTP[S] binding by the [A.sub.1] adenosine receptor agonist R-PIA and the muscarinic cholinergic receptor agonist carbamyl
choline (carbachol) were examined in 3-h incubations (Fig.
Should the carbon to oxygen bond cleave, a carbamyl
radical and an alkoxy radical will be formed.
Carbamylation of glutamate dehydrogenase and other mitochondrial proteins by biosynthetic carbamyl
Birds lack carbamyl
phosphate synthetase, one of the urea cycle enzymes necessary for the synthesis of citrulline from ornithine in the liver and kidney (Tamir and Ratner, 1963).
MS/MS has proven to be ineffective in reliably identifying deficiencies in the urea-cycle enzymes ornithine transcarbamylase (OTC) and carbamyl
phosphate synthetase (CPSI) through the quantitation of citrulline, though is considerably more useful when detecting elevations in this analyte in newborns with a deficiency in argininosuccinic acid synthetase (ASAS) or argininosuccinic acid lyase (ASAL).
phosphate synthetase gene expression is stabilized in the liver of Rana catesbeiana tadpoles during heat shock.
The hyperammonemia observed in methylmalonic acidemia is thought to arise because accumulated propionyl CoA interferes with formation of N-acetylglutamate, an obligatory activator of carbamyl
phosphate synthase, the initial step in urea synthesis (4).
phosphate and yeast orotidine-5'phosphate pyrophosphorylase were obtained from Boehringer Mannheim GmbH.
