摘要:
抗胞囊线虫病基因是大豆抗病育种的重要基因资源。目前已经在抗胞囊线虫品种中发现了两个对于抗性具有重要贡献的Rhg1和Rhg4基因，但是关于蛋白质结构和功能的信息还很少。本研究注释了RHG1和RHG4完整的结构域特征，二级结构分析显示两蛋白质均采用α/β折叠，蛋白激酶结构域的空间结构采用与所有真核生物的丝氨酸/苏氨酸及酪氨酸特异性蛋白激酶的核心相同的折叠方式，具有类似结构特点。
Abstract:
Disease resistant gene to soybean cyst nematode is important gene resource for soybean breeding.Two genes Rhg1 and Rhg4 related to cyst nematode resistance in soybean had been cloned in disease resistant cultivar，but the structure and role of RHG protein are not well understood.This paper explained the detailed domain feature of RHG protein，secondary structure analysis indicated RHG protein has an alpha beta fold，tertiary structure of protein kinase domain adopted the same fold as core structure in almost all eukaryotic serine/threonine and tyrosine kinase，and had similar structure feature according to structure prediction.
