Abstract Spermidine (Spd), spermine (Spm), and putrescine (Put), which are the most widely
distributed cellular polyamines, are essential for normal growth and multiplication of both …

Polyamines such as putrescine, spermidine, and cadaverine are small, polycationic
molecules that are required for optimal growth in all cells. The intracellular concentrations of …

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

Streptococcus pneumoniae encodes a transporter for polyamines that contributes to
virulence in an animal model. The putative polyamine-binding protein, PotD, has an amino …

Polyamines such as putrescine are small, ubiquitous polycationic molecules that are
required for optimal growth of eukaryotic and prokaryotic cells. These molecules have …

Polyamines are small, polycationic molecules with a hydrocarbon backbone and multiple
amino groups required for optimal cell growth. The potD gene, belonging to the ABC (ATP …

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

Spermine, a potent bactericidal polyamine, exerts a strong synergistic effect with β-lactams
against methicillin-resistant Staphylococcus aureus. Transcriptome analysis revealed that …

Streptococcus pneumoniae is the most common bacterial etiology of pneumococcal
pneumonia in adults worldwide. Genomic plasticity, antibiotic resistance and extreme …

Recent research has suggested that polyamines (putrescine, spermidine, and spermine) in
the intestinal tract impact the health of animals either negatively or positively. The …
