In the Ebola virus one of the proteins, VP40, has the ability to refold to achieve new functions; three structural forms of VP40 have been determined, with each structure conferring a separate and essential function in the virus life cycle. The image illustrates (top) a butterfly-shaped dimer critical for membrane trafficking; (middle) a rearranged hexameric structure essential for building and releasing nascent virions; (bottom) an RNA-binding octameric ring that controls transcription in infected cells
