Lysine amino acids, in particular, have complicated the addition of functional molecules to the N-terminus of peptides.

Likewise, lysine (y-1 ion) has been increased to 291 instead of the normal 147 for the lysine y-1 ion. The MS3 spectrum of m/z 291 from the peptide LVNELTEFAK revealed all four iTRAQ labels with ...

The functional group of lysine amino acids is an amine group that could potentially compete with the amine group present at the N-terminus of a peptide strand. Importantly, the chemical reaction ...

The peptide glycyl-ʟ-histidyl-ʟ-lysine is an endogenous antioxidant in living organisms, possibly by diminishing hydroxyl and peroxyl radicals. International journal of physiology ...

The tumour specificities and potency of miniaturized cancer targeting peptides are among the major issues of current cancer research. Over 100 peptides were evaluated in this study. According to the ...

A naturally occurring tri-peptide, GHK-Cu, consists of lysine, histidine, and glycine. The peptide GHK becomes GHK-Cu when it connects with copper in the organism, thanks to its strong Cu2+ affinity.

In proteins, lysine, arginine, and cysteine are the amino acid targets. In nucleic acids, cytosine is the target in DNA, and adenine in RNA. Methylation along with phosphorylation, acetylation ...

Lysine's precise role in the prevention and treatment of herpes labialis outbreaks is unknown. Of seven randomized, double-blind, placebo-controlled studies reviewed, six showed lysine to be ...
