A plant‐centric view of class B flavin‐dependent monooxygenase evolution and diversity

The Plant Journal, Volume 127, Issue 5, September 2026.
SUMMARY Flavin‐dependent monooxygenases (FMOs) are ancient enzymes present throughout all kingdoms of life. FMOs utilize flavin‐based cofactors to incorporate an oxygen atom into their substrate, altering its chemical properties. Class B FMOs are enriched throughout the plant kingdom, catalyzing essential reactions for plant development and defense ...

Molecular evolution of the polyamine oxidase gene family in Metazoa

BMC Evolutionary Biology, 2012
Background Polyamine oxidase enzymes catalyze the oxidation of polyamines and acetylpolyamines. Since polyamines are basic regulators of cell growth and proliferation, their homeostasis is crucial for cell life.

Putrescine, spermidine, and spermine play distinct roles in rice salt tolerance

Journal of Integrative Agriculture, 2020
Polyamines (PAs) play diverse roles in plant growth and development, as well as responses to environmental stimuli. In this study, the effects of PAs on rice salt tolerance were investigated.

Stimulation of antioxidative enzymes and polyamines during stripe rust disease of wheat

Biologia Plantarum, 2010
Content of polyamines and activities of antioxidative enzymes in response to stripe rust disease caused by Puccinia striiformis have been studied in two wheat (Triticum aestivum L.) cultivars PBW 343 (resistant) and HD 2329 (susceptible).

Bis(benzyl)polyamine analogs as novel substrates for polyamine oxidase.

Journal of Biological Chemistry, 1990
N,N'-Bis(benzyl)polyamine analogs were found to be substrates for highly purified polyamine oxidase. Metabolism of these analogs was apparently dependent on molecular O2 and resulted in the formation of benzaldehyde, H2O2, and a polyamine analog with free terminal amines.

Identification and genetic characterization of a gibberellin 2-oxidase gene that controls tree stature and reproductive growth in plum [PDF]

, 2011
Several dwarf plum genotypes (Prunus salicina L.), due to deficiency of unknown gibberellin (GA) signalling, were identified. A cDNA encoding GA 2-oxidase (PslGA2ox), the major gibberellin catabolic enzyme in plants, was cloned and used to screen the ...

Effect of Nitric Oxide Fumigation Combined with Hypobaric Treatment on the Postharvest Quality and Metabolism of Polyamines and Glutathione in Xiaobai Apricots [PDF]

Shipin Kexue
To investigate the regulatory effect of nitric oxide (NO) fumigation combined with hypobaric treatment (HYT) on the postharvest quality of Xiaobai apricots, ‘Luntai’ apricots were treated with exogenous NO under hypobaric conditions (HYT + NO).

NF-E2-related factor 1 suppresses the expression of a spermine oxidase and the production of highly reactive acrolein

Scientific Reports
Polyamines (putrescine, spermidine, and spermine) are among the most abundant intracellular small molecular metabolites, with concentrations at the mM level. The ratios of these three molecules remain constant under physiological conditions. Stress (i.e.
