Family 3 carbohydrate-binding modules (CBM3s) are associated with the scaffoldin subunit of the multi-enzyme cellulosome complex and with the family 9 glycoside hydrolases, which are multimodular enzymes that act on plant cell-wall polysaccharides, notably cellulose. Here, the crystallization of CBM3b from cellobiohydrolase 9A is reported. The crystals are tetragonal and belong to space group P4(1) or P4(3). X-ray diffraction data for CBM3b have been collected to 2.68 A resolution on beamline ID14-4 at the ESRF.
第3家族碳水化合物结合模块(CBM3s)与多酶纤维小体复合物的支架蛋白亚基以及第9家族糖苷水解酶相关,这些多模块酶作用于植物细胞壁多糖,尤其是纤维素。本文报道了来自纤维二糖水解酶9A的CBM3b的晶体结构。晶体为四方晶系,属于空间群P4(1)或P4(3)。在欧洲同步辐射装置的ID14-4光束线上收集到了分辨率为2.68 Å的CBM3b的X射线衍射数据。
