A polyamine oxidase (PAO) is an enzymatic flavoprotein that oxidizes a carbon-nitrogen bond in a secondary amino group of a polyamine donor, using molecular oxygen as an acceptor.

Polyamine oxidase (PAO) is a FAD-dependent enzyme with a molecular mass of about 62 kDa, present with high activity in most tissues of vertebrates. Structural requirements of a substrate …

Jun 21, 2019 · Polyamines can be oxidized by copper-containing diamine oxidases (CuAOs) and flavin-containing polyamine oxidases (PAOs). Two types of PAOs exist in the plant kingdom; …

Sep 2, 2022 · Polyamine oxidases (PAOs), which are flavin adenine dinucleotide-dependent enzymes, catalyze polyamine (PA) catabolism, producing hydrogen peroxide (H 2 O 2). …

Feb 1, 2023 · PAOs are flavin adenine dinucleotide-dependent enzymes with varying degrees of substrate specificity. They are expressed differentially upon various abiotic stress conditions, …

Oct 20, 2020 · Polyamine oxidases (PAOs) have an important role in polyamine metabolism and contribute to several physiological processes through regulation of polyamine levels and …

Polyamine oxidases are flavoproteins that catalyze the aerobic degradation of polyamines (e.g., spermidine to form putrescine), H2 O 2, and NH 3 (Yu et al., 2019). Polyamine oxidases …

Dec 17, 2022 · Polyamine oxidases (PAOs) terminally catabolize polyamines or catalyse the back-conversion reactions when spermine is converted to spermidine and Spd to putrescine. …

Feb 1, 2006 · The PAO from maize seedlings (MPAO), the most studied member of this enzyme class, is a 53-kDa monomeric glycoprotein tightly bound to cell walls 6, 18, 19. The MPAO …

Sep 1, 2018 · Polyamines (PAs) are implicated in developmental processes and stress responses of plants. Polyamine oxidases (PAOs), flavin adenine dinucleotide-dependent enzymes that …
