本文报道腾冲嗜热厌氧杆菌(Thermoanaerobacteriumtengcongensis,TtCheW)支架蛋白CheW的晶体结构,用分子置换法获得了2.2nm的分辨率。基于其他人报道的来自Thermotoga maritime的晶体结构TmCheA P4-P5-TmCheW,我们对TmCheA P4-P5-TtCheW复合物进行了建模,并预测TtCheW与CheA的疏水相互作用类似于TmCheW。我们还发现,从CheW的保守基序“NxxGxIxP”在CheA结合中起着重要作用。报告的突变位点相关的Chew-MCP的结合,和预测的蛋白质相互作用区域内的TtCheW分子的重合,表明Chew-MCP的结合位点位于之间的凹槽形区域TtCheW和组装模型内的CheA P4结构域。
The crystal structure of the scaffolding protein CheW from Thermoanaerobacter tengcongensis (TtCheW) is reported with a resolution at 2.2Å using molecular replacement. Based on the crystal structure TmCheA P4–P5–TmCheW from Thermotoga maritime reported by others, we modeled the TmCheA P4–P5–TtCheW complex and predicted that TtCheW is involved in a hydrophobic interaction with CheA, similar to that for TmCheW. We also found that the conserved motif “NxxGxIxP” from CheW plays an important role in CheA binding. The coincidence of the reported mutation sites related to CheW–MCP binding, and the predicted protein interaction region within the TtCheW molecule, suggest that CheW–MCP binding sites lie in the groove-shaped area between TtCheW and the CheA P4 domain within the assembled model.
