摘要:
韧皮部蛋白2(PP2)是植物特异性的韧皮部蛋白,通过参与植物调控其细胞内基因表达水平和产物活性来应对自然界中的各种胁迫,对于维持植物株体形态、体内物质运转和保护愈合植物伤口有重要意义。以前期克隆得到的黄瓜(Cucumis sativus)PP2-A1蛋白序列为对象,利用生物信息学方法,对黄瓜PP2-A1蛋白序列进行生物学功能分析。结果表明,黄瓜PP2-A1蛋白具有亲水性,比较不稳定,半衰期短,无信号肽段,没有跨膜结构,是定位在胞质的非分泌蛋白;结合对其二级结构和三级结构的预测分析,得出PP2-A1是以无规则卷曲和延伸链为主的片层结构;构建PP2的系统发育树,发现其与香瓜亲缘关系最近,同时预测其结构功能域,发现其具有1个典型的PP2结构功能域。
