摘要:采用PCR法克隆了桃褐腐病菌的角质酶基因cut1,构建了诱导型表达载体pET28a-cut1,转化大肠杆菌E.coli(BL21),获得重组菌pET28a-cut1/BL21。经异丙基-β-D-硫代吡喃半乳糖苷(IPTG)诱导,该重组菌角质酶的表达量约为对照菌的1.69倍,酶活约为对照菌的1.8倍,粗酶液的酶活可达40.33 U/mL。
The cutinase gene cutl has been cloned by a polymerase chain reaction (PCR) from Monolinia fructicola. After ligation to vector pET28a and transformation into E. coli (BL21) , a recombinant strain pET28a-cut1/ BL21 was acquired. Upon isopropyhhio-β-galactoside (IPTG) induction, this recombinant strain produced 1.69 times as much cutinase as the control strain. The maximum cutinase activity of the fermentation broth was 40. 33 U/ mL, nearly 1.8 times that of the control strain.
