Figure 4.
Distribution of helical turns for ScDmc1 and ScRad51 filaments. Number of striations per filament. ScDmc1 and ScRad51 filaments formed on linear fragments of (A) 180 bp, (B) 140 bp and (C) 100 bp. Filaments were formed in the presence of 1 mM Mg2+ and 0.5 mM AMP-PNP. Black arrows indicate predicted turns based on 19 bp/turn, grey arrows indicate predicted turns based on 24 bp/turn.
