Název v původním jazyce

Aminoaldehyde dehydrogenase activity in defence responses to mechanical injury of pea seedlings

Popis výsledku v původním jazyce

Polyamine catabolism in plants is mediated by amine oxidases. There are two types of these enzymes: copper-containing (Cu-AOs, EC 1.4.3.6) and FAD-containing (polyamine oxidases, PAOs, EC 1.5.3.-). Besides hydrogen peroxide, aminoaldehydes are formed inthe reactions of Cu-AOs and PAOs1. These aminoaldehydes are further metabolised by NAD+-dependent aminoaldehyde dehydrogenases (AMADHs, EC 1.2.1.19) to the corresponding amino acids2. Pea seedling AMADH has recently been purified to homogeneity and characterised in detail3. Plant Cu-AOs and PAOs are associated with the cell wall. A coupled function has been suggested for these enzymes and peroxidase (POD) localised in the apoplast. Both Cu-AOs and PAOs could represent sources of H2O2 for cross-linking reactions mediated by the peroxidase and thus may play an important physiologic role. A close relationship between the ligno-suberisation process and response to pathogen invasion catalysed by POD and AOs, which occur during wound healing
