From: Structure of a RecT/Redβ family recombinase in complex with a duplex intermediate of DNA annealing
Surface colors correspond to regions of positive (blue), neutral (white), and negative (red) charge. The inner DNA strand is yellow and the outer strand is orange. a Front view showing the DNA bound to outer positively charged groove. b Top view showing the positively charged upper surface of the filament. c Bottom view showing the negatively charged lower surface of the filament. d Close-up view of the narrow groove showing the strong positive charge where the backbone of the inner strand is bound.
