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 …

Polyamines are small polycationic molecules found in almost all cells and associated with a
wide variety of physiological processes. In recent years it has become increasingly clear …

Polyamines are small polycations that are well conserved in all the living organisms except
Archae, Methanobacteriales and Halobacteriales. The most common polyamines are …

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 …

Bactericidal antibiotics (fluoroquinolones, aminoglycosides and cephalosporins) at their
sublethal concentrations were able to produce hydroxyl radicals, hydrogen peroxide and …

Polyamines are primordial polycations found in most cells and perform different functions in
different organisms. Although polyamines are mainly known for their essential roles in cell …

Polyamines are small organic cations that are essential for normal cell growth and
development in eukaryotes. Under normal physiological conditions, intracellular polyamine …

Polyamines are aliphatic cations with multiple functions and are essential for life. Cellular
polyamine levels are regulated by multiple pathways such as synthesis from amino acid …

We reported previously that the synthesis of specific proteins such as OppA, Cya, and RpoS
(σ 38), which are important for cell growth and viability, is stimulated by polyamines at the …

Since their discovery by Antoni van Leeuwenhoek in 1678 until the recent development of
transgenic mice expressing proteins altering polyamine levels in a tissue-specific manner …
