Crystal structure of scaffolding protein TtCheW from Thermoanaerobacter tengcongensis
Overview
The crystal structure of the scaffolding protein CheW from Thermoanaerobacter tengcongensis (TtCheW) is reported with a resolution at 2.2A 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.
