| Abstract: | Summary. The nucleotide sequences of genome segments S6, S7 and S10 of Dendrolimus punctatus cypovirus 1 Hunan I (DpCPV-HN(I)) and DpCPV-HN(I)-Se3 (DpCPV-HN(I) passed three times in Spodoptera exigua) were determined. Segment S10 was 944 nucleotides in length and encoded a polyhedrin of 248 amino acids (28 439 Da). Only two nucleotide mutations were found between DpCPV-HN(I) S10 and DpCPV-HN(I)-Se3 S10, and the deduced amino acid sequences of the polyhedrin proteins were identical. Segment S7, 1 501 nucleotides, encoded a protein of 448 amino acids ( 50kDa; p50). Thirty-one nucleotide mutations were found between DpCPV-HN(I) S7 and DpCPV-HN(I)-Se3 S7, but these resulted in only four amino acid changes. DpCPV-HN(I) S6 encoded a protein of 561 amino acids (63 688Da; p64). The amino acid sequence of p64, had a high leucine content (10%), and contained a leucine zipper motif and one ATP/GTP-binding site motif. |
