Transport of Diamines by Enterococcus faecalis Is Mediated by an Agmatine-Putrescine Antiporter [PDF]

, 1988
Enterococcusfaecalis ATCC 11700 is able to use arginine and the diamine agmatine as a sole energy source. Via the highly homologous deiminase pathways, arginine and agmatine are converted into CO2, NH3, and the end products ornithine and putrescine ...

Plant Identity Shapes Core Microbiomes on Green Roofs

Environmental Microbiology Reports, Volume 18, Issue 6, December 2026.
Three plant species selected from coal mine spoil heaps using a trait‐based approach were associated with distinct bacterial and fungal microbiome patterns in extensive green roof substrates. Discriminant taxa and differences in predicted metabolic pathways provided complementary taxonomic and functional perspectives on plant‐associated substrate ...

Mitochondrial Respiratory Metabolism in Salt‐Stressed Barley (Hordeum vulgare): TCA Cycle Activation With Limited GABA Shunt Engagement

Plant, Cell &Environment, Volume 49, Issue 12, Page 10042-10060, December 2026.
ABSTRACT Plants maintain energy balance under salinity stress through increased respiration and energy use, processes also associated with reactive oxygen species generation. Although respiration imposes a high energy cost, mitochondrial respiration and the tricarboxylic acid (TCA) cycle activity are vital for ATP production and for providing electron ...

Putrescine priming effects on chlorophyll fluorescence, antioxidant enzyme activity, and primary metabolite accumulation in maize seedlings under water deficit

Biologia Plantarum
This study aimed to evaluate the effect of putrescine priming on the initial growth, chlorophyll fluorescence, primary metabolites accumulation, and antioxidant enzyme activities in two maize hybrids with contrasting drought tolerances. Seeds of Zea mays

EBV‐Driven ODC1 Upregulation Enhances Polyamine Anabolism to Promote Viral Replication and Cisplatin Resistance in Nasopharyngeal Carcinoma

Advanced Science, Volume 13, Issue 61, 3 November 2026.
EBV‑BZLF1 initiates ODC1‑driven polyamine anabolism that correlates with poor clinical prognosis in nasopharyngeal carcinoma. The ODC1–spermidine axis promotes viral replication, cell proliferation and innate immune evasion. Pharmacological inhibition of ODC1 rescues cisplatin sensitivity, establishing ODC1 as a viable therapeutic target for EBV ...

Putrescine metabolism in pea seedligs

, 2015
The effect of putrescine (Putr.) and N-carbamoylputrescine (N-CPutr.) fed to excised pea seedlings was studied. Contrary to great toxicity of higher than 0.5% Putr., N-CPutr. even at higher concentration was not toxic for the plants.

Novel NaV1.6‐Mitochondrial Complexes in Retinal Astrocyte Pockets Sequester GABA

Glia, Volume 74, Issue 11, November 2026.
NaV1.6 localizes in retinal astrocytes' high density pockets on the bilayer facing the ganglion cell layer. NaV colocalizes with large, anaplerotic mitochondria. These microdomains accumulate high levels of GABA. ABSTRACT Voltage‐gated sodium channels are best known for their capacity to generate and propagate electrical currents in neurons and muscle.

Putrescine reverses aconitine-induced arrhythmia in rats

, 1989
Putrescine, (150–300 mg kg−1 i.v.) injected into anaesthetized rats reversed aconitine-induced arrhythmia and restored sinus rhythm. In the same experimental model, quinidine and lignocaine had a transient therapeutic effect, procainamide was practically

An Ascorbic‐Acid Containing Poly(Carbonate) Urethane With Antioxidant Bioactivity for Application in Heart Valve Scaffold Development

Journal of Biomedical Materials Research Part A, Volume 114, Issue 11, November 2026.
ABSTRACT Prosthetic heart valve development consists of several branching, innovative strategies to mediate the complex native environment that wears down valve durability. Anti‐calcification treatments are being applied to pericardial tissue, durable polymers are being developed that mitigate oxidative degradation and stress cracking, and heart valve ...

Ischemia-induced and reperfusion-induced arrhythmias are prevented by putrescine

, 1991
The influence of putrescine on cardiac arrhythmias induced by either permanent ligature of the left anterior coronary artery or heart reperfusion following a 5-min coronary occlusion was studied in anesthetized rats. Reperfusion-induced arrhythmias were
