Polylysine refers to several types of lysine homopolymers, which may differ from each other in terms of stereochemistry (D/L; the L form is natural and usually assumed) and link position (α/ε). Of these types, only ε-poly-L-lysine is produced naturally.

comment
  • La ε-polilisina è un piccolo omo-polipeptide dell'amminoacido essenziale lisina prodotto da fermentazione batterica. L'epsilon (ε) incluso nel nome indica il sito di legame delle molecole di lisina, che a differenza dei normali peptidi legati tramite il gruppo in posizione α, gli amminoacidi sono qui legati tramite il gruppo amminico in ε e il gruppo carbossilico per mezzo di legame ammidico.
  • ポリリジン（ε-ポリ-L-リジン、EPL）は、必須アミノ酸の一つL-リジンの低分子天然ホモポリマーで、細菌による発酵によって生産される。ε-ポリ-L-リジンは、食品の天然の防腐剤として使用される。
  • La polylysine est un polymère organique composé de lysine. Cette dernière est un acide aminé qui présente un premier groupe amine en position α et un second en position ε, de sorte qu'on distingue l'α-polylysine de l'ε-polylysine. Il existe deux énantiomères de la lysine : la L-lysine, qui un acide aminé protéinogène, et la D-lysine, qui n'est pas présente naturellement dans les protéines. On distingue par conséquent deux α-polylysines : la poly-L-lysine (PLL) et de la poly-D-lysine (PDL) ; et deux ε-polylysines : l'ε-poly-L-lysine (EPL), qui est généralement produite sous la forme d'un homopolymère d'environ 25 à 30 résidus de L-lysine, et de l'ε-poly-D-lysine (EPD).
