Figure 1

Structure of hUpf1hd and its comparison with PcrA and Vasa helicases. The ribbon diagrams are drawn with domains 1A (pink) and 2A (wheat) in the same orientation. Bound nucleotide is shown in stick model and Mg2+ ion in purple sphere. (A) hUpf1hd-AMPPNP. Domains 1B and 1C are colored in lime and slate, respectively. (B) The PcrA/ADPNP/dsDNA complex. Domains 1B and 2B are shown in lime and yellow respectively. Bound DNA is shown in orange cartoon tube. (C) The Vasa/AMPPNP/ssRNA complex. Bound ssRNA is shown in purple cartoon tube.
