It allows for binding of the reductase to DNA via electrostatic interactions, since it has a predominance of positive charges distributed on its surface [1].

The four stranded beta-sheet forms a saddle-shaped surface and assembles together through an interface made of alpha-helices. The presence of 14 basic residues on the surface of the beta-sheets suggests that this large groove may be involved in DNA binding [1].
