“Here, we examined the … of the flanking lysine and arginine residues in … reactivity 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.”
“Increasing the dietary SID Leu Lys resulted in a linear increase in plasma Leu concentration (P < 0.001) and quadratic increases (P < 0.001) in plasma Cys concentration.”

“However, at late incubation time points, tissues which had been preloaded with ornithine or lysine accumulated higher intracellular concentrations of cysteine than unloaded controls.”
“Here we report the discovery of a covalent crosslink between a cysteine and a lysine residue with a NOS bridge that serves as an allosteric redox switch in the transaldolase enzyme of Neisseria gonorrhoeae, the pathogen that causes gonorrhoea.”
“Repeated daily administration of cysteine and lysine for a week caused a significant decrease in the eosinophil count of the skin, duodenum and colon.”
