Possible Interaction: Arginine and Nitrogen

“Our study unravels the main arginine import and export systems of the yeast vacuole and suggests that they are inversely regulated by nitrogen.”

“The removal of nitrogen via alternative pathway lowers the flux of arginine in the urea cycle.”

“PN nitrogen and energy supplies were significantly higher during R periods than during S periods.”

“Sodium benzoate, sodium phenylbutyrate and arginine can exploit alternative pathways for the elimination of nitrogen but haemodialysis or haemofiltration should be instituted if ammonia concentrations are >500 micromol/l or if they do not fall promptly.”

“Animal studies conducted by Harvey and Gibson showed that simultaneous supplementation with glycine, proline and arginine produced an increase of as much as 60-70% in nitrogen retained.”

“Additionally, the arginine treatment affected serum concentrations of nitrogenous and lipid signaling molecules (glycerophosphorylcholine and myo-inositol) and intestinal bacterial metabolites (formate, ethanol, methylamine, dimethylamine, acetate, and propionate).”

“At the same time determination of autolysis and proteolysis by amino nitrogen in the presence of arginine has shown that autolytic and proteolytic activities increased.”

“A compensatory mechanism was shown to exist when cyanide and nitrogen were used to inhibit the oxidative catabolism of arginine.”

“The data indicates, on the other hand, that excess arginine (1.7%) contributes in part, to the retention of nitrogen.”

“Our data reveal that arginine acts as a negative signal for the assimilation of nitrogen within the ammonium-CYG56 negative signalling cascade, and provide a connection between amino acid metabolism and nitrogen assimilation in microalgae.”
