Possible Interaction: Arginine and Cysteine

“Here, we examined the role of arginine 120 in modulating the pK(a) values of these cysteines.”

“Here, we examined the potential … the flanking lysine and arginine residues in influencing … of the cysteine and the DNA-binding activity of Fos and Jun. Two sets of Fos and Jun mutants were … and KSR series representing proteins capable of redox-dependent and redox-independent DNA-binding activity, respectively.”

“We identified a novel homozygous missense mutation (c.790T>C) in the GP1BAgene that causes an amino acid residue substitution of a cysteine with an arginine that might have a deleterious effect on the protein function as predicted by bioinformatics analysis.”

“Substitution of arginine with cysteine at position 203 decreases the affinity of the protein for DNA, thereby destabilizing the protein.”

“The effect of L-cysteine was synergistically enhanced by L-arginine in the refolding buffer.”

“Lysine, ornithine, arginine and cystine or cysteine showed marked mutual inhibition of tubular reabsorption.”

“At pH 6.0, cysteine can only interact with arginine through the ion-pair interaction and such interaction can lead to the changes in both the solution color and UV-vis spectrum of the cysteine-protected Au-NPs upon the addition of arginine.”

“The rationale for the method is based on the pH-dependent feature of the interionic interaction between cysteine and arginine.”

“The d-isomers of R in the Manse-AS analog appeared to prevent hydrolysis by cathepsin L cysteine and trypsin-like enzymes, and enhance its half-life (145 min).”

“Furthermore, AA plus cysteine supplementation reduced significantly urinary nitrogen excretion and muscle wasting.”

“The position of 4 half-cystines and 8 arginines overlaps.”
