• PubMed Abstract: 
  

  Eukaryotic organisms cap the 5' ends of their messenger RNAs by a series of four chemical reactions. Some viruses achieve this using a single molecule; the crystal structure of such an enzyme from bluetongue virus reveals an elongated modular architecture that provides a scaffold for an assemblage of active sites, two contributed by a domain of novel structure.
