Protein secrets of Ebola virus

This is a ribbon diagram showing the tertiary structure with secondary-structure elements identified and labeled.The current Ebola virus outbreak in West Africa, which has claimed more than 2000 lives, has highlighted the need for a deeper understanding of the molecular biology of the virus that could be critical in the development of vaccines or antiviral drugs to treat or prevent Ebola hemorrhagic fever. Now, a team at the University of Virginia (UVA), USA – under the leadership of Dr Dan Engel, a virologist, and Dr Zygmunt Derewenda, a structural biologist – has obtained the crystal structure of a key protein involved in Ebola virus replication, the C-terminal domain of the Zaire Ebola virus nucleoprotein (NP) [Dziubanska et al. (2014). Acta Cryst. D70, 2420-2429; doi:10.1107/S1399004714014710]
