Glutamate, Ornithine, Arginine, Proline, and Polyamine Metabolic Interactions: The Pathway Is Regulated at the Post-Transcriptional Level [PDF]
, 2016 The metabolism of glutamate into ornithine, arginine, proline, and polyamines is a major network of nitrogen-metabolizing pathways in plants, which also produces intermediates like nitric oxide, and γ-aminobutyric acid (GABA) that play critical roles in ...

SPERMINE OXIDASE: AN AMINE OXIDASE WITH SPECIFICITY FOR SPERMINE AND SPERMIDINE [PDF]
Journal of Experimental Medicine, 1953 Sheep serum and bovine serum contain an enzyme which brings about a rapid oxidative deamination of certain biological amines. This enzyme differs from previously described amine oxidases in several regards and especially in its substrate specificity.

Plant Biotechnology Journal, EarlyView.BAHD acyltransferases drive metabolic diversification in plants by coupling conserved catalytic scaffolds with regulatory flexibility, enabling stress adaptation and ecological specialisation. ABSTRACT BAHD acyltransferases constitute one of the most versatile enzyme superfamilies in plants, catalysing the acylation of alcohols, amines, polyamines, and

Antibacterial Action of Oxidized Spermine [PDF]
Journal of General Microbiology, 1964 SUMMARY: Spermine oxidized by partially purified serum amine oxidase inhibited the growth of a variety of Gram-positive and Gram-negative bacteria. This inhibition of growth was not antagonized by calcium ion, and occurred over a wide pH range. Inactivation increased with time and temperature of incubation.

Plant, Cell &Environment, EarlyView.ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

ChemMedChem, Volume 21, Issue 9, 14 May 2026.The anticancer activity of the complexes Pd3Spd2, Pt3Spd2, Pt2Put2(NH3)4 and Pd2Put2 against human TNBC, non‐TNBC and healthy breast cells was evaluated. The metabolic impact of the most promising metal complexes—Pd3Spd2 and Pt2Put2(NH3)4—was further assessed using vibrational microspectroscopies, providing detailed insights into the drug‐induced ...

The porin and the permeating antibiotic: A selective diffusion barrier in gram-negative bacteria [PDF]
, 2008 Gram-negative bacteria are responsible for a large proportion of antibiotic resistant bacterial diseases. These bacteria have a complex cell envelope that comprises an outer membrane and an inner membrane that delimit the periplasm.
