Substrate specificity of peroxidases

Nevertheless, the substrate specificity of peroxidases is so wide that secretory plant peroxidases are capable of accepting a plethora of natural compounds as substrates, such as indoles [43], porphyrins [44,45] including chlorophylls [46,47], terpenoids such as lutein [48], unsaturated lipid acids such as linoleic acid [49], alkaloids [50-52] including betacyanins [53], phenolics such as benzoic acids [54,55], DOPA [56], coumarins [38,57], stylbenes [58], catechins [36,59], chalcones [60], flavonols [61,62], isoflavones [63,64], cinnamyl alcohols and cinnamic acids [65,66], anthocyanins [67,68] and ascorbic acid [69,70],...
