Thermisch hergestelltes Polylysin beschleunigt die Ubertragung von Aminogruppen des Harnstoffs auf α-Ketoglutarsaure. Das pH-Optimum dieser Reaktion, die die Anwesenheit von Cu-Ionen erfordert, liegt bei 7.00. Die Transaminierungsreaktion folgt derMichaelis-Menten-Kinetik. Thermisch hergestelltes Polylysin wird durch Erhitzen in Pufferlosungen nicht inaktiviert, wahrend Depolymerisation oder Modifizierungen der Aminogruppen den Verlust der Aktivitat zur Folge haben.
