体外催化花生四烯酸生产前列腺素F2αIn vitro catalytic production of prostaglandin F2α using arachidonic acid
前列腺素F2α(PGF2α)具有广泛的生理活性,是一种重要的脂质介质。为了实现PGF2α的绿色生物合成,构建了pET30a-TbPGFS、pET30a-MmPGHS、pET30a-GvPGHS载体并在大肠杆菌BL21(DE3)中分别表达,同时对异丙基-β-D-硫代半乳糖苷(IPTG)诱导表达条件进行了优化以提高重组蛋白在大肠杆菌中的表达量。另外,以最佳诱导表达条件下得到的重组蛋白为催化剂,催化花生四烯酸合成PGF2α。结果表明:MmPGHS蛋白在大肠杆菌中没有表达;GvPGHS蛋白的最佳诱导表达条件为诱导剂IPTG浓度0.2 mmol/L、诱导温度30 ℃、诱导时间2 h,TbPGFS蛋白的最...
