Description
技术领域
本申请属于微生物技术领域,尤其涉及一种代谢工程方法、产角鲨烯工程菌、产橙花叔醇工程菌及其构建方法、应用。
背景技术
随着合成生物学的发展,酿酒酵母已被广泛作为异源表达宿主来生产有价值的天然产物,这些天然产物包括单萜吲哚生物碱、青蒿酸和大麻素等。为了更加充分地利用酵母细胞工厂,越来越多的代谢工程策略被开发出来。对基因启动子和终止子的操控,以及对代谢通路上下游基因的融合、支架蛋白的构建和细胞器区室化的策略在一些重要化合物的生物合成中起到了很大的促进作用,同时,对酵母细胞内源亚细胞结构内质网膜的修饰能够提高角鲨烯及三萜类化合物的产量。
长非编码RNA在肿瘤细胞的发展和浸润过程中起着至关重要的作用。细胞内有一类能够募集组蛋白修饰复合物的转录因子,而长非编码RNA可指引这类转录因子到达染色体的指定位置,间接引起组蛋白结构的修饰,进而发挥调控作用。例如,长非编码RNAPCGEM1是前列腺癌细胞潜在的生物标记物和治疗靶点,它能够结合转录组因子c-Myc,调控糖酵解、三羧酸循环及脂质合成等代谢途径,进而引起细胞代谢流的重排。虽然在癌细胞中对长非编码RNA和原癌基因的研究很多,但在酵母细胞中的研究还比较少,而更进一步,将长非编码RNA和原癌基因开发成为一种代谢工程策略还未见报道。
