摘要:
由于丙酮醛降解酶(methylglyoxal degradation enzyme,MD)是生物体内代谢丙酮醛的一种关键酶,实现MD的高效表达对调控丙酮醛的代谢途径具有重要意义。所以根据Schizosaccharomyces pombe_GeneDB中MD的基因序列(SPAC22E12.03C)设计引物,以粟酒裂殖酵母(Schizosaccharomyces pombe )cDNA文库为模板通过PCR扩增技术得到目标基因,目的片段全长576 bp。将SPAC22E12.03C连接到pET-28a(+)上,得到重组质粒pET-28a(+)-SPAC22E12.03C,并在Escherichia coli BL2l(DE3)中实现表达。同时,对其目的蛋白的表达条件进行了优化,获得最佳表达条件:诱导温度37 ℃,诱导起始菌体D600 nm为0.5~0.6,诱导剂IPTG浓度为0.8 mmol/L。这为研究粟酒裂殖酵母体内丙酮醛的降解途径打下了坚实基础。
