ANALYSIS AND EXPRESSION OF HYPHANTRIA CUNEA NUCLEAR POLYHEDROSIS VIRUS sod GENE
美国白蛾核型多角体病毒超氧化物歧化酶基因的序列分析和表达

The sequencing results indicated that \%Hyphantria cunea\% nuclear polyhedrosis virus (HcNPV) \%sod\% gene open reading frame of 456 nt encoding protein of 151 amino acid,was identified to that of Bombyx mori nuclear polyhedrosis virus (BmNPV), and exhibited 97 2% homology at nucletde level to that of \%Autographa californica\% nuclear polyhedrosis virus (AcNPV),three amino acid residues difference in amino acid level with AcNPV sod.The essential amino acid residues for the construction and active could be detected in HcNPV sod.Activity of the SOD is 147 09U per milliliter E.coli.
