In this study, a recombinant fusion antigen of duck enteritis virus (DEV) UL16 protein was expressed in Escherichia coli Rossetta (DE3). This target protein was used as a coating antigen to establish an indirect ELISA for detecting anti-DEV antibodies in serum samples from ducks. In the optimal method for the UL16-ELISA, the fusion protein was coated at 1.25μg/ml and duck serum samples were diluted...
In the study, we calculated the codon usage bias in the newly identified UL38 gene of Duck Enteritis Virus (DEV) and performed a correlation analysis of codon bias of DEV UL38 gene and its host animal. There was a strong bias in the DEV UL38 gene towards the synonymous codons with A and T at the third codon position. The amino acids codon usage bias in the DEV UL38 gene was compared with other 15...
We determined the nucleotide sequence of a portion of the duck enteritis virus (DEV) strain CHv which was suspected to be the UL10 gene(GenBank accession no EU195100.), encoding glycoprotein M(gM). The UL10 gene was cloned and sequenced, which was composed of 1230 nucleotides encoding 409 amino acids, with a predicted molecular mass of 45.752 kDa. We calculated the codon usage bias in the newly identified...
Glycoprotein K encoded by the DEV-UL53 gene is one of the DEV envelope glycoproteins. Like most members of the alphaherpesvirinae, the genes in the UL region of its genome are well conserved, which means that the major DEV envelope glycoprotein K possessing similar functions of envelope glycoprotein K of alphaherpesvirinae plays an essential role in viral replication and cell fusion. Glycoprotein...
Prediction of B cell epitopes of duck enteritis virus (DEV) VP19c protein encoded by UL38 gene and expression in prokaryotic system were described in the present study. The major antigenic portion of VP19c protein of DEV was predicted and corresponding gene was amplified from the extracted DNA and cloned. The recombinant expression construction(pPAL7-truncated UL38) was identified by the polymerase...
The US4 open reading frame of the Duck enteritis virus (DEV) encodes glycoprotein G, a protein comprising 459 amino acids with a putative molecular mass of 50.58 kDa. The characteristics of this protein were analyzed through bioinformatics softwares and tools. Glycoprotein G sequence analysis indicates that the protein possesses typical characteristics of membrane glycoproteins containing two transmembrane...
The Us4 gene homologue of duck enteritis virus (DEV) was cloned by degenerate polymerase chain reaction (PCR) and sequenced. DEV Us4 gene open reading frame (ORF) was 1380 bp in length and its primary translation product was a polypeptide of 459 amino acids long. Phylogenetic tree of the nucleotide sequences showed this gene had a close evolutionary relationship with GaHV-1 and PsHV-1, but the DEV...
The analysis on codon usage bias of gI gene of duck enteritis virus (DEV) may provide a basis for understanding the evolution and molecular characteristic of DEV, and for selecting appropriate host expression systems to improve the expression of target gene. A comparative analysis of the codon usage bias of the DEV gI gene and 22 other refrence herpesviruses gI-like genes was performed, by using the...
