Determination of di-/Polyamine Oxidase Activity in Plants by an In-Gel Spermidine Oxidation Assay

, 2018
Diamine and polyamine catabolism controls plant development, resistance to pathogens and stress responses. Diamine and polyamine oxidases control the catabolism of diamines and polyamines, respectively. Two major routes of di-/polyamine catabolism exist:

Polyamine oxidase activity contributes to sustain maize leaf elongation under saline stress [PDF]

, 2009
The possible involvement of apoplastic reactive oxygen species produced by the oxidation of free polyamines in the leaf growth of salinized maize has been studied here. Salt treatment increased the apoplastic spermine and spermidine levels, mainly in the

Molecular Cloning, Subcellular Localization, and Abiotic Stress Induction Analysis of a Polyamine Oxidase Gene from Oryza sativa

International Journal of Agronomy, 2023
Abiotic stress is a major bottleneck for crop productivity. To counter abiotic stresses, plants have developed several strategies, and the accumulation of polyamine (PA) serving as an osmolyte is one of them.

Comparative genomics and evidence for an unusual polyamine oxidation pathway in aquatic duckweed (Spirodela polyrhiza L.)

Current Plant Biology
Polyamines (PA) cellular levels are maintained through a balance between synthesis and catabolism, achieved by two classes of enzymes polyamine oxidases (PAOs) and copper amine oxidases (CuAO). Here we investigated the occurrence, molecular evolution and

Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

Animal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and

Crystallization and preliminary X-ray analysis of polyamine oxidase from Zea mays L.

, 1998
Polyamine oxidase catalyses the oxidation of the secondary amino group of spermine, spermidine and their acetyl derivatives. The enzyme plays an important role in the regulation of polyamine intracellular concentration and is a member of the family of ...

A New Transgenic Mouse Model for Studying the Neurotoxicity of Spermine Oxidase Dosage in the Response to Excitotoxic Injury.

PLoS ONE, 2013
Spermine oxidase is a FAD-containing enzyme involved in polyamines catabolism, selectively oxidizing spermine to produce H2O2, spermidine, and 3-aminopropanal. Spermine oxidase is highly expressed in the mouse brain and plays a key role in regulating the

Activation of endoplasmic reticulum stress response by enhanced polyamine catabolism is important in the mediation of cisplatin-induced acute kidney injury.

PLoS ONE, 2017
Cisplatin-induced nephrotoxicity limits its use in many cancer patients. The expression of enzymes involved in polyamine catabolism, spermidine/spermine N1-acetyltransferase (SSAT) and spermine oxidase (SMOX) increase in the kidneys of mice treated with ...
