The way to a virus' 'heart' is through its enzymes

The arrival of bluetongue virus (BTV) in the UK last year posed a major threat to the economy and the increasing temperatures of our changing climate mean it is here to stay. If we are to fight this disease, which has had a major impact on farming already, we must discover how it works. A review published in the August issue of the Journal of General Virology outlines our current understanding of the "heart" of the virus, which may help us to develop antiviral therapies to treat many human pathogens.
