The gene encoding ornithine decarboxylase for putrescine biosynthesis is essential for the viability of Fusobacterium nucleatum

Journal of Bacteriology
Fusobacterium nucleatum is a Gram-negative anaerobe associated with periodontitis and colorectal cancer. It secretes putrescine, a polyamine that promotes biofilm formation by oral co-colonizers and enhances the proliferation of cancer cells.

SAT1‐Induced Spermidine Depletion Potentiates Food Allergy

Advanced Science, EarlyView.
Spermidine depletion, driven by upregulated spermidine/spermine N1‐acetyltransferase (SAT1), potentiates food allergy by promoting mast cell degranulation through autophagy suppression. SAT1 physically interacts with the long noncoding RNA Cdk19os to inhibit Atg5 and Atg7, disrupting autophagic flux.

Amyloid‐Guided Assembly of Magnetically Recyclable Enzymatic Nanofibers Toward Sustainable Biocatalysis

Advanced Science, EarlyView.
A hierarchical strategy integrates linker engineering, amyloid‐guided self‐assembly, and magnetic immobilization to construct recyclable DPAO4‐DMAO7 enzymatic nanofibers. The resulting magnetic composites enable biogenic amine conversion in complex food matrices and simulated wastewater, while rapid magnetic separation supports repeated reuse. The work

Putrescine and Acid Stress [PDF]

Plant Physiology, 1983
Incubation of peeled oat Avena sativa L. var Victory leaf segments on media of pH 5.0 or below leads to a rapid and massive increase in the titer of putrescine while incubation at pH values above 5.0 causes little or no change. The low pH effect is independent of the buffer system employed.

Amino Acid and Biogenic Amine Profiles in Sausages Reformulated With Processed, Fermented Oyster Mushrooms

ChemFoodChem, EarlyView.
This research showed that sausage reformulation preserves high essential amino acid and branched‐chain amino acid content, as well as increasing free amino acids (FAA) related to umami flavor and health‐promoting components such as GABA in the products.

Changing root system architecture through inhibition of putrescine and feruloyl putrescine accumulation [PDF]

FEBS Letters, 1994
Plant roots provide anchorage and absorb the water and minerals necessary for photosynthesis in the aerial parts of the plant. Since plants are sessile organisms, their root systems must forage for resources in heterogeneous soils through differential branching and elongation [(1988) Funct. Ecol. 2, 345‐351; (1991) Plant Roots: The Hidden Half, pp.

Control of pili synthesis and putrescine homeostasis in Escherichia coli

eLife
Polyamines are biologically ubiquitous cations that bind to nucleic acids, ribosomes, and phospholipids and, thereby, modulate numerous processes, including surface motility in Escherichia coli.

Putrescine Is an Intraspecies and Interkingdom Cell-Cell Communication Signal Modulating the Virulence of Dickeya zeae

Frontiers in Microbiology, 2019
The infections caused by Dickeya zeae become a severe problem in recent years, but the regulatory mechanisms that govern the bacterial virulence remain to be fragmental.
