FIG. 1.
Alignment of the predicted amino acid sequences of the pro-pol open reading frame in WDSV, WEHV1, and WEHV2. The seven conserved domains in RT are shown with brackets. LPQG and YMDD are indicated by four asterisks. The five conserved regions of RNase H are outlined in blocks labeled I through V. Identity with respect to WDSV (-), gaps (.), and differences between WEHV1 and WEHV2 are in bold-faced type. Amino acid changes between WEHV2 subclones are indicated in parentheses.
