The porcine adenovirus NADC-1 isolate, a strain of porcine adenovirus type 4, has a fibre with an atypical architecture. In addition to a classical virus attachment region, shaft and head domains, it contains an additional galectin like domain C-terminal to the head domain and connected to the head domain by a long RGD-containing loop. The galectin-like domain contains two putative carbohydrate-recognition domains. The head and galectin-like domains have been independently crystallized. Diffraction data have been obtained to 3.2 angstrom resolution from crystals of the head domain and to 1.9 angstrom resolution from galectin-like domain crystals.
猪腺病毒NADC-1分离株,即4型猪腺病毒的一个毒株,其纤维具有非典型结构。除了经典的病毒附着区域、杆部和头部结构域外,它在头部结构域的C端还含有一个额外的半乳糖凝集素样结构域,并通过一个含有RGD的长环与头部结构域相连。该半乳糖凝集素样结构域包含两个假定的碳水化合物识别结构域。头部结构域和半乳糖凝集素样结构域已分别结晶。已从头部结构域晶体获得了分辨率为3.2埃的衍射数据,从半乳糖凝集素样结构域晶体获得了分辨率为1.9埃的衍射数据。
