Figure 2.
Sedimentation velocity ultracentrifugation confirms the importance of L381. Experiments for DnaB, L381A, and τ proteins (A), as well as the DnaB-τ and DnaB–L381A mixtures (B) are shown. Data are presented as Gaussian distribution of apparent sedimentation coefficients and show an interaction between DnaB and τ but not between DnaB and L381A.
