Abstract

The Cucurbitaceae family accumulates hydrophobic organic pollutants in its aerial parts at high concentrations. Major latex-like proteins (MLPs) were identified in zucchini (Cucurbita pepo) as a transporting factor for hydrophobic organic pollutants. MLPs bind to hydrophobic organic pollutants in the roots, are secreted to xylem vessels as complexes, and are transported to the aerial parts. However, the suitable conditions for binding MLPs to hydrophobic organic pollutants remain elusive. In the present study, we show that MLPs bind to the hydrophobic organic pollutant pyrene with higher affinity under acidic conditions. Our results demonstrated that pH regulates the binding of MLPs to hydrophobic organic pollutants.

主要的乳胶样蛋白在与疏水性有机污染物结合时表现出pH依赖性。
葫芦科植物在其地上部分积累高浓度的疏水性有机污染物。西葫芦中的主要乳胶样蛋白(MLPs)被鉴定为疏水性有机污染物的转运因子。MLP与根中的疏水性有机污染物结合,作为复合物分泌到木质部导管中,并运输到地上部分。然而,将MLP与疏水性有机污染物结合的合适条件仍然难以捉摸。在本研究中,我们发现MLPs在酸性条件下以更高的亲和力与疏水性有机污染物芘结合。我们的研究结果表明,pH调节MLP与疏水性有机污染物的结合。
