Uses
Penta lysine is an antibacterial agent, that inhibits E. coli, A. baumannii, P. aeruginos, S. aureus, and B. subtilis, with MIC of 1.1-18 μM[1].
Biochem/physiol Actions
Short poly-L-lysines polypeptides such as trilysine (lys3), tetralysine (tetra-L-lysine, lys4) and pentalysine (penta-L-lysine, lys5) are cationic moieties that may be used in the construction of gene delivery vectors and DNA nanoparticles.
