Polyamines are positively charged hydrocarbons that are essential for the growth and
cellular maintenance in prokaryotes and eukaryotes. Polyamines have been demonstrated …

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 common intracellular metabolites of nearly all cells, and their conservation
across a vast diversity of cells suggests critical roles for these compounds in cellular …

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

Nitrogen is an essential element required for bacterial growth. It serves as a building block
for the biosynthesis of macromolecules and provides precursors for secondary metabolites …

Polyamines such as cadaverine, putrescine and spermidine are polycationic molecules that
have pleiotropic effects on cells via their interaction with nucleic acids. Streptococcus …

One of the main issues in modern medicine is the decrease in the efficacy of antibiotic
therapy against resistant microorganisms. The advent of antimicrobial resistance has added …

Polyamines such as spermidine and spermine are primordial polycations that are
ubiquitously present in the three domains of life. We have found that Gram‐positive bacteria …

Streptococcus pneumoniae has a potential ABC-type transporter (Pot) for extracellular
polyamines. Polyamine transport protein D (PotD) is a membrane-associated, surface …
