Effect of window size and distance cutoff parameter combinations on capture of structure fragments. A: sequence variability profile around position G64 generated by running StralSV against the PDB database; red type: data for position G64. B: Numbers of structure fragments selected from a custom library comprising 38 polymerase chains plus randomly selected structures from PDB; red type: numbers corresponding to distance cutoff and window_size values selected as defaults for StralSV web service. C: Structure fragment of poliovirus polymerase (1ra6) corresponding to the N-terminal region containing position G64; color variations dark blue to bright turquoise indicate N-to-C-terminal direction of chain.
