The stromal-cell-derived factor 2-like protein of Arabidopsis thaliana (AtSDL) has been shown to be highly up-regulated in response to unfolded protein response (UPR) inducing reagents, suggesting that it plays a crucial role in the plant UPR pathway. AtSDL has been cloned, overexpressed, purified and crystallized using the vapour-diffusion method. Two crystal forms have been obtained under very similar conditions. The needle-shaped crystals did not diffract X-rays, while the other form diffracted to 1.95 A resolution using a synchrotron-radiation source and belonged to the hexagonal space group P6(1), with unit-cell parameters a = b = 96.1, c = 69.3 A.
拟南芥的基质细胞衍生因子2样蛋白(AtSDL)已被证明在响应未折叠蛋白反应(UPR)诱导试剂时高度上调,这表明它在植物UPR途径中起关键作用。AtSDL已被克隆、过表达、纯化并使用气相扩散法结晶。在非常相似的条件下获得了两种晶体形式。针状晶体不能衍射X射线,而另一种形式使用同步辐射源衍射到1.95 Å分辨率,属于六方空间群P6(1),晶胞参数a = b = 96.1,c = 69.3 Å。
