Lysine is commonly used as a treatment; however, in a 2015 systematic review, the authors investigated all clinical trials with cats as well as in vitro studies and concluded that lysine supplementation is likely not effective for the treatment or prevention of feline herpesvirus 1 infection. [15]
Lysine ball and stick model spinning. Lysine (symbol Lys or K) [2] is an α-amino acid that is a precursor to many proteins.Lysine contains an α-amino group (which is in the protonated −NH + 3 form when the lysine is dissolved in water at physiological pH), an α-carboxylic acid group (which is in the deprotonated −COO − form when the lysine is dissolved in water at physiological pH ...

Double-stranded DNA phage lysins tend to lie within the 25 to 40 kDa range in terms of size. A notable exception is the streptococcal PlyC endolysin, which is 114 kDa. PlyC is not only the biggest and most potent lysin, but also structurally unique since it is composed of two different gene products, PlyCA and PlyCB, with a ratio of eight PlyCB subunits for each PlyCA in its active conformation.
The precursor amino acid lysine contains two amino groups, one at the α-carbon and one at the ε-carbon. Either can be the location of polymerization , resulting in α-polylysine or ε-polylysine. Polylysine is a homopolypeptide belonging to the group of cationic polymers : at pH 7, polylysine contains a positively charged hydrophilic amino group.
LysE appears to catalyze unidirectional efflux of L-lysine (and other basic amino acids such as L-arginine), and it provides the sole route for L-lysine excretion. The energy source is believed to be the proton motive force (H + antiport). The E. coli ArgO homologue (TC# 2.A.75.1.2) effluxes arginine and possibly lysine and canavanine as well. [5]
Allysine is a derivative of lysine that features a formyl group in place of the terminal amine. The free amino acid does not exist, but the allysine residue does. It is produced by aerobic oxidation of lysine residues by the enzyme lysyl oxidase. The transformation is an example of a post-translational modification.
