Possible Interaction: Arginine and Tyrosine

“Here, we report that cooperative cation-π interactions between tyrosines in the LC domain and arginines in structured C-terminal domains also contribute to phase separation.”

“Investigation of the residues positioned in between two RNA bases demonstrates that tyrosine and arginine have favored stacking interactions.”

“The concentrations of arginine (7.95 vs 5.2 micromol/l), tyrosine (14.3 vs 12.5 micromol/l) and phenylalanine (10.7 vs 9.5 micromol/l) were significantly elevated in neutrophil homogenate from uremic patients before HD and after HD for arginine (8.73 micromol/l).”

“By contrast, in CSF, serine, threonine, and tyrosine decreased (-20, -24, and -31%, respectively) after R feeding.”

“In contrast, the binding of tyrosine and arginine was actually greater when the older enzyme preparations were employed.”

“Both tyrosine and tryptophan, but not phenylalanine, were able to quench the emission of the fluorescent probe by more than 80% upon the addition of arginine.”

“More importantly, they were found to have a profound effect on the luminescence responses to arginine compared with glutamic acid, histidine, tryptophan, threonine, tyrosine and phenylalanine in aqueous environment.”

“3 Neither l‐NAME, d‐NAME, l‐arginine nor d‐arginine was able to inhibit ONOO−‐dependent nitration of tyrosine , suggesting that they are unlikely to be scavengers of ONOO−‐derived nitrating species.”

“The interactions of phenylalanine and arginine with tyrosine relatively decrease the conformational effects of the primary amino group.”

“…,Y, … - R = P - R + D - X, where P is a protein, D - R a small molecule, and X a group in the protein that interacts negatively … high energy X-donor from a low energy one and may be of importance in metabolism, particularly in the oxidative phosphorylation of ADP.”
