Therapeutic target database update 2018: enriched resource for facilitating bench-to-clinic research of targeted therapeutics.

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. To study structur...
