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.
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.
