Disease relevance of AT5G06720

Anionic Arabidopsis thaliana peroxidase ATP A2 was expressed in Escherichia coli and used as a model for the 95% identical commercially available horseradish peroxidase HRP A2 [1].

High impact information on AT5G06720

Two of these genes, AtBCB and parB, and a peroxidase gene from Arabidopsis (AtPox) also showed increased resistance to oxidative stress induced by diamide, while parB conferred resistance to Cu and Na [2].
Thus coniferyl and p-coumaryl alcohol could be preferentially oxidized by different peroxidase isoforms in this suspension culture, which may reflect a control mechanism for the incorporation of different monolignols into the cell wall [3].
Docking of p-coumaryl, coniferyl and sinapyl alcohol in the substrate binding site of ATP A2 were analysed on the basis of the crystal structure of a horseradish peroxidase C-CN-ferulic acid complex [4].
