Polyamines, nonprotein amino acids and alkaloids
Cadaverine synthesis
The diamine cadaverine is derived from the amino acid lysine by decarboxylation. Its synthesis is catalyzed by lysine decarboxylase [EC 4.1.1.18]. Cadaverine may play an important role in root development (Gamarnik and Frydman, 1991).
