General description

Lysine is a basic ketogenic amino acid with a protonated alkyl amino group. Lysine degradation results in the formation of acetoacetate. Acetylation/deacetylation of lysine residues in histones is a mechanism to regulate chromatin organization in eukaryotes. Isotope labeled amino acids are required for the production of isotopically labeled proteins.


• L-Lysine-13C6,15N2 hydrochloride has been used in pSILAC (pulsed stable isotope labeling by amino acids in cell culture) mass spectrometry to study protein profile in cells transfected with microRNAs.
• It has been used in SILAC isotopic labeling for the characterization of lysine racemase.
• It has been used in SILAC labeling for phosphoproteomic measurements in neuro-2a cells treated with and without GFKP-19 (2-pyrrolidone derivative).

Pulsed Stable Isotope labeling of amino acid has been used to study host-cell function, survival, the precise intracellular pathways in protein synthesis of HIV-1 infected human monocytederived macrophages.
