丁香假单胞菌极毛蛋白hrpA基因的克隆与表达
Cloning and expression of hrpA gene of Pseudomonas syringae
摘要
Abstract
HrpA gene was obtained from Pseudomonas syringae pv. Tomato DC3000 by PCR and the protein expression system of Escherichia coli BL21 (DE3) for hrpA was constructed with vector pET32a( + ). SDS-PAGE analysis showed that the transformant with recombinant expression plasmid pET32a ( + ) - hrpA produced a fusion protein of TrxA-HrpA with corresponding molecular weight of 28 ku. Furthermore, HrpA recombination protein was purified through Ni2 + -NTA and its concentration was measured to be 91.8 g·L-1.关键词
