ABSTRACT
Objective To analyze the conding region of hantanvirus S gene and predict the structure of nucleoprotein for diagnostic antigen study.Methods RT-PCR was used to amplify the S gene of hantanvirus Hunan03 strain after designing specific primers.The amplification product was cloned into pGM-T vector and then the recombinant vector was transformed into E.coli TOP10,gene sequencing was carried out after blue-white selection and PCR screening for positive clones.The database of NCBI and Swiss-Prot/TrEMBL were used to predict and analyze the structure,biological characteristics and protein structures of S gene.Results The amplification product was about 1290 bp,the pGM-T/S vector was constructed and successfully sequenced,the whole length of the open reading frame (ORF) was composed of 1290 nucleotide residues,among them the GC content was 44.11% and the AT content was 55.89%,it was composed of 429 amino acids (20 kinds),the accession number of the sequence submitted to GenBank was JN712306,its homology of nucleotides to the 76-118 strain was 83% and the homology of amino acids was 98%,ten nonspecific variation sites were found.The grand average of hydropathicity was-0.405.There were three transmembrane domains and four non transmembrane domains in the secondary structure of nucleoprotein including 55% of helix structure,6.1% of sheet structure and 38.9% of loop structure.Conclusion The bioinformatics analysis of Hunan03 strain S gene might be important for provide the substructure data to reveal the significance of S gene characteristics on hemorrhagic fever renal syndrome (HFRS) prevention and control.
