[Abstract]  Hydroxyproline-rich glycoproteins (HRGPs) are major protein components in dicot primary cell walls and generally account for more than 10% of the wall dry weight. As essential members of the HRGP superfamily, extensins (EXTs) presumably function in the cell wall by assembling into positively charged protein scaffolds (Cannon et al., 2008) that direct the proper deposition of other wall polysaccharides, especially pectins, to ensure correct cell wall assembly (Hall and Cannon, 2002; Lamport et al., 2011a). Extensins are recalcitrant to purification as they are rapidly ... [摘要]  富含羟脯氨酸的糖蛋白(HRGP)是双子叶原代细胞壁中的主要蛋白质组分,通常占壁干重的10%以上。作为HRGP超家族的主要成员,通过装配到带正电荷的蛋白质支架(Cannon等人,2008)中,可以推测伸展蛋白(EXT)在细胞壁中起作用,其指导其他壁多糖的适当沉积,特别是果胶,以确保正确的细胞壁组装(Hall和Cannon,2002; Lamport等人,2011a)。延伸素难以纯化,因为它们在进入细胞壁后快速交联成共价网络,但是存在可以提取新合成的延伸蛋白单体的短时间窗(Smith等人, 1984; Smith等人,,1986)。用于提取延伸蛋白和其他壁结构蛋白的详细方案早已被描述(Lamport等人,2011b)。这里详述的方案提供了一种方法,用于使用AFM在体外研究延伸素和潜在地其他细胞壁组分的自组装。
