  Detection of 210 kDa receptor protein for a leaf-movement factor by using novel photoaffinity probes

  摘要：

  Circadian rhythmic plant leaf-movement, called nyctinasty, is controlled by a time-course change in the internal concentration of the leaf-movement factor in the plant body. We revealed that specific binding proteins (210 and 180 kDa) for the leaf-movement factor, potassium lespedezate (1), are contained in the plasma membrane of the plant motor cell by using novel synthetic photoaffinity probes. These proteins are localized on the motor cell in the plant body, and would be potential receptors for the leaf-movement factor to control the leaf-movement. Our study is a rare successful result of the detection of membrane receptors by using a synthetic photoaffinity probe designed on a biologically active natural product. And these results also advance a guideline for probe design towards successful photoaffinity labeling. (c) 2005 Elsevier Ltd. All rights reserved.

  基于叶片运动因子的新型生物活性光亲和探针的合成，该探针对其受体分子具有潜在的高结合亲和力

  摘要：

  叶片运动因子与植物小叶植物中运动细胞的结合诱导了芥子叶运动。叶片运动因子的某些受体应参与此生物学事件。我们开发了一种新型的光亲和探针（1）用于检测受体分子。探针化合物1在糖苷部分的2'-位置带有一个光标记基团，该基团靠近该分子与其受体的潜在结合位点。这种分子设计对于提高光标记产率是有效的。

  Circadian rhythmic plant leaf movement, called nyctinasty, is controlled by a time-course change in the internal concentration of the leaf-movement factor in the plant body. We report that specific binding protein (210 and 108 kDa) for a leaf movement factor, potassium lespedezate, is contained in the plasma membrane of the plant motor cell. These proteins Would be potential receptors for leaf-movement factor to control the leaf movement. (C) 2003 Elsevier Ltd. All rights reserved.
