煙粉虱MED隱種氣味結(jié)合蛋白基因BtabOBP2和BtabOBP4的cDNA克隆及原核表達
[Abstract]:Cloning of Bemisia tabaci (Gennadius) odor binding protein (odorant binding protein, from whitefly by RT-PCR and RACE techniques OBP) BtabOBP2 and BtabOBP4. BtabOBP2 (Gen Bank accession number: AIS71883) and BtabOBP4 (Gen Bank accession number: AIS71884) cDNA sequence is 1107 bp and 874 bp, complete open reading frame (ORF) is 744 bp and 429 bp, respectively. Encoding 247 and 142 amino acids, respectively, BtabOBP4 has six conserved cysteines, which belong to typical OBP, while BtabOBP2 adds three conserved cysteines to Plus-C OBP. in addition to the six cysteine of typical OBP. The obtained BtabOBP2 and BtabOBP4 were recombined into the prokaryotic expression vector pET30a (), and transformed into BL21 (DE3) Escherichia coli competent cells. IPTG was used to induce the expression of the fusion protein. The fusion protein was purified by affinity chromatography and gel filtration chromatography and analyzed by Western blot. The results showed that both BtabOBP2 and BtabOBP4 fusion proteins were soluble expressed in E. coli. The Western blot results confirmed that the expressed fusion protein was the target protein. The apparent molecular weight of the BtabOBP2 fusion protein in SDS-PAGE was 6.53k Da, higher than the predicted molecular weight, and the 6 脳 His label was removed by recombinant enterokinase. The apparent molecular weight of the target protein was similar to that of the predicted molecular weight, and the deviation was decreased, which indicated that the 6 脳 His tag was the cause of the apparent molecular weight deviation of the fusion protein. In this study, the nucleotide and amino acid sequence characteristics of BtabOBP2 and BtabOBP4 genes of Bemisia Tabaci odor binding protein were confirmed, and the prokaryotic expression and purification were successfully carried out, which laid a foundation for further study on the molecular structure and function of these two OBP genes.
