The structure of the RNA-dependent RNA polymerase (RdRP) from the rabbit hemorrhagic disease virus has been determined by x-ray crystallography to a 2.5-A resolution. The overall structure resembles a "right hand," as seen before in other polymerases, including the RdRPs of polio virus and hepatitis C virus. Two copies of the polymerase are present in the asymmetric unit of the crystal, revealing active and inactive conformations within the same crystal form. The fingers and palm domains form a relatively rigid unit, but the thumb domain can adopt either "closed" or "open" conformations differing by a rigid body rotation of approximately 8 degrees. Metal ions bind at different positions in the two conformations and suggest how structural changes may be important to enzymatic function in RdRPs.

Publication Abstract from PubMedThe structure of the RNA-dependent RNA polymerase (RdRP) from the rabbit hemorrhagic disease virus has been determined by x-ray crystallography to a 2.5-A resolution. The overall structure resembles a "right hand," as seen before in other polymerases, including the RdRPs of polio virus and hepatitis C virus. Two copies of the polymerase are present in the asymmetric unit of the crystal, revealing active and inactive conformations within the same crystal form. The fingers and palm domains form a relatively rigid unit, but the thumb domain can adopt either "closed" or "open" conformations differing by a rigid body rotation of approximately 8 degrees.
