Researchers at the European Molecular Biology Laboratory (EMBL) in Grenoble, France, have determined the detailed 3-dimensional structure of part of the flu virus' RNA polymerase, an enzyme that is crucial for influenza virus replication. This important finding is published today in PLoS Pathogens. The research was done on the 2009 pandemic influenza strain but it will help scientists to design innovative drugs against all the different influenza strains, and potentially lead to a new class of anti-flu drugs in the next 5-10 years.
The scientists focused on the endonuclease part of the viral RNA polymerase.
