For HSV: the virus requires arginine for capsid protein synthesis and DNA replication. Lysine and arginine compete for the same intestinal transporter (CAT-1) and cellular entry mechanisms. High lysine intake (1) reduces arginine absorption, (2) reduces arginine entry into cells, (3) increases arginase activity (breaking down intracellular arginine). The net effect: reduced intracellular arginine starves the virus of a replication requirement. For collagen: lysine residues in procollagen are hydroxylated by lysyl hydroxylase (vitamin C-dependent) and then oxidatively cross-linked by lysyl oxidase (copper-dependent), forming the structural cross-links that give collagen tensile strength.
