Most of the phylogenetic diversity of life is found in bacteria and archaea, and is reflected in
the diverse metabolism and functions of bacterial and archaeal polyamines. The polyamine …

Polyamines are polycationic molecules with a hydrocarbon backbone and multiple amino
groups. Descriptions of the physiological roles of polyamines have often been limited to their …
