Recombinant ptotein made up 39.2%(pET-20b-bglA) and 33.5%(pET-28a-bglA) of the total proteins in the intracellular fraction, the solubility proportion of the enzyme up to 32.8%(pET-20b-bglA) and 40.1%(pET-28a-bglA), the activities of the enzyme were 66.8 (pET-20b-bglA) and 71.2 U/mg (pET-28a-bglA). These results showed that E. coli BL21-CodonPlus (DE3)-RIL with argU tRNA, ileY tRNA and leuW tRNA genes helped to improve expression of the enzyme through enhanced identification of the rare codons AGA/AGG, AUA and CUA. Further optimized the conditions for inducing, the solubility proportion of the enzyme was 70.6% at 16 °C and 1.2 times higher than 37 °C. The solubility proportion of the enzyme increased from 12.3% to 32.8% when IPTG concentrations dropped from 1000 μM to 25 μM. The recombinant enzyme was purified by heat treatment, DEAE Sepharose anion-exchange chromatography and TOYOPEARL HW-55F.

maritima MSB8 的-葡萄糖苷酶基因 bglA克隆至表达载体 pET-20b 和 pET-28a，构建重组质粒 pET-20b-bglA 和 pET-28a-bglA，然后转化不同大肠杆菌 E.coli 宿主，Tm-SIGlA 在 E.coli BL21-CodonPlus(DE3)-RIL 中获得高效表达，重组蛋白的表达量为 33.5%(pET-28a-bglA)和 39.2%(pET-20b-bglA)，可溶性比例为 32.8%(pET-20b-bglA)和 40.1%(pET-28a-bglA)，比酶活达 66.8 (pET-20b-bglA)和 71.2 U/mg (pET-28a-bglA)，这些结果表明，E.coli BL21-CodonPlus(DE3)-RIL 宿主带有的 argU tRNA、ileY tRNA 和 leuW tRNA 基因，分别增强对稀有密码子 AGA/AGG、AUA 和 CUA 的识别，有助于提高该酶在 E.coli 中的表达；进一步优化诱导条件，重组 E.coli BL21-CodonPlus(DE3)-RIL/pET-20b-bglA 在 37 ℃下诱导培养，IPTG 浓度由 1000 μM 降至 25 μM，目的蛋白可溶性表达由 12.3%增至 32.8%，提高 1.7 倍，16 ℃下低温诱导实现目的蛋白 70.6%的可溶性表达，较 37 ℃下诱导培养提高 1.2 倍。
