The inner diameter of b-CD cone is 0.65nm and the extra is 1.53nm. The hydroxyl groups of C(6)(the sixth carbon atoms of glucose unit and the same as follows) are located on the smaller opening of the cone with counterclockwise direction, while the hydroxyl groups of C(2) and C(3) are located on the larger opening of the cone with reverse direction.

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。
