We studied the influence of xenobiotics of various chemical natures, including N,N'-dicyclohexylcarbodiimide, diethylstilbestrol, and chlorpromazine, on the activity of peroxidase, a redox-enzyme that participates in defense reactions of plants. It was shown that the influence of the studied xenobiotics on severed roots of wheat seedlings caused an increase in the permeability ofplasmalemma for K+ and H+ and stimulated the activity of the extracellular peroxidase that forms the superoxide radical anion. It is assumed that the extracellular peroxidase can initiate the transformation of alien compounds on the cell surface, before their entrance into the cells.
我们研究了各种化学性质的异生素，包括N，N'-二环己基碳二亚胺、己烯雌酚和氯丙嗪，对过氧化物酶活性的影响，过氧化物酶是一种参与植物防御反应的氧化还原酶。结果表明，所研究的异生素对小麦幼苗离体根的影响导致质膜对K+和H+的通透性增加，并刺激了形成超氧自由基阴离子的细胞外过氧化物酶的活性。据推测，细胞外过氧化物酶可以在外来化合物进入细胞之前启动其在细胞表面的转化。
