Flexibility analysis. Sausage plot for (A) template S. pyogenes SufU and (D) model E. faecalis SufU proteins. The thickness presented is directly related to the flexibility in the area. Loops are presented in gray, α-helices in red and β-strands in blue. Root Mean Square Fluctuation (RMSF) analysis, as a function of both residue number and time for (B) template S. pyogenes and (C) E. faecalis SufU proteins, presenting the four α-helices (H), the three β-strands (S), and the GPR region.
