1OLO - PubMed Abstract: 
In the known monoclinic crystals the 3-dimensional structure of the hexameric, replicative helicase RepA encoded by plasmid RSF1010 shows 6-fold rotational symmetry. In contrast, in the cubic crystal form at 2.55 A resolution described here RepA has 3-fold symmetry and consists of a trimer of dimers ...
