1.10.3.3	evolution	AAO belongs to the large family of multicopper oxidases. AAO labelling in the cytosol, walls and chloroplasts of Chaetomorpha linum cells, whereas in angiosperms this enzyme is almost exclusively confined to the extracellular matrix, possible function of AAO in adaptation and functional evolution of its cellular location, overview	724853	
1.10.3.3	evolution	AOase occurs only in higher plants	717986	
1.10.3.3	evolution	phylogenetic tree of plant ascorbate oxidases, overview	726244	
1.10.3.3	malfunction	a diminution in ascorbate oxidase activity affects carbon allocation and improves yield in tomato under water deficit, overview. RNAi knockout plants show increased fruit yield under three conditions where assimilate became limiting for wild-type plants: when fruit trusses are left unpruned, when leaves are removed or when water supply is limited. Several alterations in the transgenic lines can contribute to the improved yield and favour transport of assimilate from leaves to fruits in the ascorbate oxidase lines. RNAi lines show altered sink strength	-, 726138	
1.10.3.3	metabolism	stability of total vitamin C in situ was strongly dependent on the plant maturity stage and the processing conditions applied	725176	
1.10.3.3	metabolism	the enzyme is involved in catalyzing the oxidation of apoplastic ascorbic acid to dehydroascorbic acid	764784	
1.10.3.3	additional information	a rapid and sensitive ratiometric fluorescence sensing method for the detection of ascorbic acid and ascorbate oxidase is developed	765849	
1.10.3.3	additional information	partially folded monomeric species might populate the energy landscape of the enzyme. The overall AAO stability is crucially controlled by a few quaternary interactions at the subunits' interface	724962
