Abstract
Bovine viral diarrhea virus (BVDV) is a member of the Flaviviridae family of viruses and constitutes a very important pathogen for livestock around the world [1]. The viral helicase is an enzyme essential for the proliferation and transmission of the virus. In this work a 3D-model of the BVDV helicase was produced using homology modelling techniques and the known 3D-structure of the hepatitis C helicase of the Flaviviridae family as template, in an attempt to provide the means for structure-based design of novel anti-BVDV agents.
