Ascorbic acid oxidase (AAO) has been fully characterized at molecular level, yet its functional role is unclear. The properties of the enzyme and the main hypotheses on its function are discussed. Recent data and reappraisal of previous observations suggest that AAO could be part of a dynamic mechanism operating whenever plant cells have to control oxygen availability.

Keywords: ascorbic acid; dioxygen
Subjects: ascorbate, ascorbic acid; ascorbic acid oxidase; auxins; dehydroascorbic acid, dehydroascorbate reductase; dendrogram, phylogenetic tree; glutathione reductase; phylogenetic tree, dendrogram; polymerase chain reaction (PCR)
