Anionic peroxidase (IEP approximately 3.5) and oxalate oxidase (IEP approximately 7.0) were isolated from wheat seedlings using chitin. The strength of binding of enzymes with chitin depended on the degree of its acetylation and ionic strength of buffer. It was assumed that the acetyl groups of chitin are involved in sorption of enzymes on this biopolymer. The ability of anionic peroxidase and oxalate oxidase for sorption on chitin allows this biopolymer to be used for isolation of these proteins from plants. Cosorption of anionic peroxidase and oxalate oxidase on chitin suggests that these enzymes cooperate to ensure defensive response of wheat against chitin-containing pathogens.
