Analysis and expression of the polyhedrin gene of Antheraea pernyi nucleopolyhedrovirus (AnpeNPV)
ABSTRACT
The polyhedrin (polh) gene is often used to analyse evolution of baculovirus. In this report, the polh of Antheraea pernyi nucleopolyhedro-virus (AnpeNPV) was cloned and sequenced. The Open reading frame (ORF) of the AnpeNPV consists of 738 nucleotides encoding 245 amino acids with molecular masses of 29 kDa. The deduced amino acids were significant homol-ogy with other baculoviruses, such as Attacus ricini NPV (ArNPV) and Autographa californica NPV (AcNPV). A strongly hydrophilic region was predicted at positions from 30 to 50 of the An-peNPV Polh protein by bioinformatics analysis. Expression of the polh gene of AnpeNPV in E. coli was examined by SDS–PAGE, Western blot and Mass-spectrum analysis. The result showed that the bacterium expression system was suitable for the virus gene expression. It indi-cated that the products of the polh gene ex-pressed in this system can be easier to use for raising antibodies.
