Birnaviruses are dsRNA viruses. The RNA dependent RNA polymerase, also known as VP1, contains the conserved RdRp motifs that reside in the catalytic "palm" domain of all classes of polymerases but in a characteristic permuted order, thus, it adopts a unique active site topology [2,3]. Additionally, the birnavirus RdRps lack the highly conserved Gly-Asp-Asp (GDD) sequence, a component of the proposed catalytic site of this enzyme family that exists in the conserved motif VI of the palm domain of other RdRps [1,2,3]. This entry covers the thumb domain of RdRP from Birnaviruses.	Domain

This entry corresponds to the C-terminal domain of RNA dependent RNA polymerase also known as VP1. All of the birnavirus VP1 proteins contain conserved RdRp motifs that reside in the catalytic "palm" domain of all classes of polymerases. However, the birnavirus RdRps lack the highly conserved Gly-Asp-Asp (GDD) sequence, a component of the proposed catalytic site of this enzyme family that exists in the conserved motif VI of the palm domain of other RdRps [1]. This RdRp has the five essential RNA polymerase motifs in a permuted order of C-A-B-D-E to form a conserved catalytic active site [2,3]. This domain is mostly alpha-helical that runs across the canyon in the front of the palm, and wraps around the fingers subdomain [2], which may function to prevent back-primed RNA synthesis during protein priming.
