Peroxidase cell wall
WebWe previously identified two cell wall peroxidases, PRX33 and PRX34, involved in apoplastic hydrogen peroxide (H2O2) production in Arabidopsis (Arabidopsis thaliana). Here, we describe the generation of Arabidopsis tissue culture lines in which the expression of PRX33 and PRX34 is knocked down by antisense expression of a heterologous French ... WebHere, the enzyme cross-links phenolic residues of cell wall polysaccharides and glycoproteins, which serve to strengthen the cell wall components. Does peroxidase produce oxygen? The rate of oxygen production by peroxidases was greatly enhanced by the addition of ABTS [2,2′-azino-bis-(3-ethylbenzthiazoline-6-sulfonic acid)] or chlorpromazine ...
