Description
技术领域
本发明涉及生物技术领域,尤其涉及一种生产甜茶苷的酿酒酵母及其应用。
背景技术
甜茶苷(Rubusoside,Rubu)是主要从广西甜茶(茶、糖、药三位一体,“天然降血糖植物”)中提取的一种甜菊糖类的甜味剂。甜菊糖,又名甜菊糖苷,具有高甜度(蔗糖的300~450倍)、低热值(蔗糖的1/300)等特点,天然蔗糖替代品,被誉为“世界第三糖原”。甜菊糖是从甜叶菊中萃取甜菊糖苷净化而来的产物。甜茶苷除了作为甜味剂以外,还具有一定的药理作用,例如,降低血糖、激活胰岛素、抗癌活性等。但是植物中甜茶苷的产量较低 (甜茶苷含量低于5%),且植物生长周期长、人工提取成本高,限制了甜茶苷的大量生产。为了解决这个问题,需要培育富含甜茶苷的新品种,但其所需要的先进技术和设备都仰赖大量资金。即便在甜菊糖的最大出口国中国,大多数生产商也无法负担得起。目前采用基因工程法构建基因工程菌株从头合成天然产物其具有低成本、原料不受限制、提取过程简单、无季节性、生产时间短,对环境污染小等诸多优点,从而受到广大学者的青睐。
微生物发酵法具有可持续性、绿色环保的社会经济效益,采用微生物发酵法生产莱甜茶苷是解决上述问题的有效途径。目前,关于甜茶苷合成途径关键基因的多个研究已指出(倪洪涛等,甜菊糖生物合成相关基因的研究进展;李铭敏等,甜菊糖苷的生物合成途径与生物转化制备策略的研究概述),植物体内甜菊糖苷(SGs)的生物合成途径与赤霉素具有相关性,它们的共同前体是由焦磷酸异戊二烯(IPP)缩合成的牻牛儿牻牛儿焦磷酸(GGPP),经过一系列酶的作用,催化形成甜菊醇和赤霉素,而甜菊醇再通过各类UDP- 糖基转移酶(UGTs)合成各类甜菊糖苷(stevioside,SGs)。具体地,牻牛儿焦磷酸合酶(GPPS)催化IPP和二甲基丙烯基二磷酸(DAMPP)形成牻牛儿焦磷酸(GPP),法呢基焦磷酸合酶(FPPS)催化GPP形成法呢基焦磷酸(FPP),FPP经牻牛儿牻牛儿焦磷酸合酶(GGPPS)催化生成GGPP,GGPP在环化焦磷酸合酶(CPPS)的作用下脱氢形成环化焦磷酸(CPP), CPP在贝壳杉烯合酶(KS)的催化下环化成贝壳杉烯,重排生成四环的贝壳杉烯,合成的贝壳杉烯转移到内质网中,在依赖细胞色素P450的单加氧酶(KO)的作用下转化成贝壳杉烯酸,贝壳杉烯酸在贝壳杉烯酸羟化酶(KAH) 的作用下,发生C13位脱氢氧化形成甜菊醇。甜菊醇经糖基转移酶UGT85C2、糖基转移酶UGT74G1等进行糖基化反应合成了各类SGs,比如甜茶苷。
中国专利CN201010569609.2公开了一种利用黄杆菌胞内酶提取和快速生产甜茶苷的方法,将黄杆菌活化后破碎,取上清,以甜菊糖为底物进行转化制备甜茶苷;中国专利CN201310460493.2利用微生物生产甜菊糖苷类化合物的方法,在宿主细胞(大肠杆菌、毕赤酵母或酿酒酵母)中重组表达非甜叶菊来源的糖基转移酶UGTB1或IBGT,还表达了(a)牻牛儿基牻牛儿基焦磷酸合成酶GGPPS,(b)古巴焦磷酸合成酶CDPS和贝壳烯合成酶KS,或双功能贝壳烯合酶,(c)贝壳烯氧化酶KO,(d)细胞色素P450氧化还原蛋白 CPR,(e)贝壳烯酸-13α-羟化酶,(f)UGT85C2糖基转移酶,(h)UGT74G1糖基转移酶,和(i)UGT76G1糖基转移酶。但上述方法生产的甜茶苷产量仍有待提高或并未生成甜茶苷,且目前未有关于微生物发酵法以葡萄糖为底物从头合成甜茶苷的相关报道。
发明内容
为解决上述技术问题,本发明提供了一种生产甜茶苷的菌株,以酿酒酵母为出发菌株,构建了甜茶苷合成途径,过表达酿酒酵母中的ABC外排泵 YOR1、PDR11或PDR12,以此实现从头合成甜茶苷和甜茶苷的高效生产。

进一步地,甜菊醇合酶基因kah的核苷酸序列如SEQ ID NO.7所示。酿酒酵母P450酶(KO和KAH)经过增加基因拷贝数、构建底物传输系统系统等策略解除P450酶的限速步骤,从而加速生成甜茶苷。
进一步地,UDP葡萄糖基转移酶基因ugt74g1的核苷酸序列如SEQ ID NO.8所示。
进一步地,UDP葡萄糖基转移酶基因ugt85c2的核苷酸序列如SEQ ID NO.9所示。
进一步地,通过双向启动子Pgal1/10调控甜茶苷合成基因的表达。双向启动子Pgal1/10由β-半乳糖和葡萄糖共同诱导的启动子Gal1和Gal10组成,启动子Pgal1/10的核苷酸序列如SEQ ID NO.10所示。敲除酿酒酵母中的gal80 基因,解除β-半乳糖对Pgal1/10的调控,获得由葡萄糖调控的酿酒酵母菌株。
进一步地,上述生产甜茶苷的酿酒酵母以酿酒酵母S.cerevisiae CEN PK2-1CMATa;ura3-52;trp1-289;leu2-3,112;his3Δ1;MAL2-8C;SUC2为出发菌株。

酿酒酵母是又称面包酵母或者出芽酵母,是与人类关系最广泛的一种酵母,作为食品安全菌株已用于制作面包和馒头等食品、酿酒工业。近年来,学者们开始研究利用酿酒酵母生产天然产物,如青蒿酸、三七皂苷等。相比大肠杆菌而言,酿酒酵母具有高安全性,低致病性,高抗逆性,而且受噬菌体污染的概率较低等优点,因此它也在基因工程领域发挥着重要作用。然而,酿酒酵母中没有甜茶苷合成的代谢通路。因此,本发明中将甜茶苷的合成途径整合至酿酒酵母,由于甜茶苷合成的前体IPP和DMAPP积累对细胞生长有毒,因此选用葡萄糖抑制型启动子Pgal1/10,将细胞生产与生长解耦联,发酵初期培养细胞生长,待葡萄糖耗尽后,Pgal控制的甜茶苷途径基因开始表达促使产物合成以达到高效合成甜茶苷的效果。同时,强化甜茶苷合成前体 IPP和DMAPP合成过程中的关键限速酶的表达以提高IPP和DMAPP的生成,优化羟化酶P450强化中间产物向目标产物甜茶苷的转化,以及过表达INO2最大程度在酿酒酵母中积累甜茶苷。但是,甜茶苷在胞内积累会限制其产量进一步提升,因此本发明还通过鉴定并强化甜茶苷的外排系统进一步提高酿酒酵母中甜茶苷的生产性能。
本发明的第二个目的是提供一种上述生产甜茶苷的酿酒酵母菌株的构建方法,包括以下步骤:
(1)将基因表达框Pgal10-ks插入酿酒酵母菌株基因组中的gal80位点,将启动子Pgal1/10与cpr1和ko的基因表达框整合至1014a位点,将启动子Pgal1与kah的基因表达框整合至1039a位点,将启动子Pgal1/10与ugt76g1 和ugt85c2的基因表达框整合至sap155b位点,将启动子Pgal1与fpps的基因表达框整合至1021b位点;其中,将基因表达框插入gal80位点,敲除了酿酒酵母中的gal80基因,解除了β-半乳糖对Pgal1/10的调控;
(2)增加甲羟戊酸途径中的关键限速酶基因idi的拷贝数;切除羟基甲基戊二酰-CoA还原酶基因hmg1的N端内质网定位信号肽获得thmg1,增加thmg1的拷贝数,强化甜茶苷合成前体;过表达INO2以扩大内质网;过表达ABC外排泵以强化其外排系统,ABC外排泵为YOR1、PDR11和PDR12 中的至少一种,得到上述生产甜茶苷的酿酒酵母菌株。
本发明的第三个目的是提供ABC外排泵YOR1、PDR11或PDR12在提高可生产甜茶苷酿酒酵母的甜茶苷产量中的应用,具体地,增强可生产甜茶苷酿酒酵母中YOR1、PDR11或PDR12的表达,可生产甜茶苷酿酒酵母为表达甜茶苷合成基因的酿酒酵母。优选地,过表达PDR11。更优选地,同时过表达YOR1、PDR11和PDR12。
进一步地,鉴定酿酒酵母中甜茶苷外排泵的方法为,预测酿酒酵母质膜上外排泵蛋白结构,通过与甜茶苷进行分子对接初步筛选出甜茶苷的外排泵,再通过ABC外排泵抑制剂进行进一步筛选,分别敲除筛选出的外排泵,对比对应酿酒酵母的甜茶苷产量,筛选出酿酒酵母中对甜茶苷外排起重要作用的外排泵。
本发明通过结构预测、分子对接以及ABC外排泵抑制剂筛选出甜茶苷的外排泵主要包含ABC外排泵家族,再通过敲除ABC外排泵,发现YOR1, PDR11,和PDR12敲除后,甜茶苷的产量降低至1倍以上。通过过表达以上三个外排泵后,发现PDR11是甜茶苷的主要外排泵。PDR11过表达后甜茶苷的产量从67mg/L提升至155mg/L,细胞形态恢复正在,生长OD明显提高。
本发明的第四个目的是提供一种生产甜茶苷的方法,采用上述生产甜茶苷的酿酒酵母菌株发酵生产甜茶苷。
进一步地,以葡萄糖为底物。
进一步地,将上述生产甜茶苷的酿酒酵母菌株接种至以葡萄糖和蔗糖为碳源的无菌培养基,在30-40℃下通气发酵。将30-40℃,180-250rpm条件下培养15-20h的种子,以1-10%的接种率转入发酵培养基,于30-40℃, 180-250rpm条件下培养,优选108小时。
进一步地,种子培养基为含有15-25g/L葡萄糖、2-10mg/L组氨酸、2-10 mg/L色氨酸和2-10mg/L亮氨酸的酵母基础培养基。
进一步地,发酵培养基的成分为5-15g/L酵母粉、15-25g/L蛋白胨和 15-25g/L葡萄糖。
本发明提供的生产甜茶苷的酿酒酵母菌株在生物、制药、食品或化工领域均有巨大的应用潜力,如用于制备甜茶苷或含有甜茶苷的产品等。
借由上述方案,本发明至少具有以下优点:
本发明以甜茶苷为最终目标产品进行代谢改造,通过引入甜茶苷合成途径相关基因,选用葡萄糖抑制型启动子调控甜茶苷合成途径相关基因的表达,强化内质网大小调节因子INO2的表达,并考虑到甜茶苷积累的抑制作用,进一步强化外排系统,提供了一种重组酿酒酵母,实现了微生物发酵法以葡萄糖为底物发酵高效生产甜茶苷,并弱化其胞内积累,为代谢工程改造酿酒酵母从头合成甜茶苷奠定了基础。

实施例1甜茶苷从头合成重组酿酒酵母菌株C1的构建
根据法呢基焦磷酸合酶基因fpps(NCBI ID:P08836.2,核苷酸序列如 SEQ IDNO.4所示)、贝壳杉烯合酶ks(NCBI ID:Q9UVY5,核苷酸序列如SEQ ID NO.5所示)、贝壳杉烯酸氧化酶ko(NCBI ID:AAQ63464.1,核苷酸序列如SEQ ID NO.6所示)、甜菊醇合酶kah(NCBIID:NP_197872.1,核苷酸序列如SEQ ID NO.7所示)、UDP葡萄糖基转移酶ugt74g1(NCBI ID:Q6VAA6.1,核苷酸序列如SEQ ID NO.8所示)和UDP葡萄糖基转移酶 ugt85c2(NCBI ID:Q6VAB0.1,核苷酸序列如SEQ ID NO.9所示),按照酿酒酵母密码子偏好性进行密码子优化并进行全基因合成。将基因表达框 Pgal10-ks插入基因组中的gal80位点,将启动子Pgal1/10(核苷酸序列如SEQ ID NO.10所示)与cpr1和ko的基因表达框整合至1014a位点,将启动子 Pgal1与kah的基因表达框整合至1039a位点,将启动子Pgal1/10与ugt76g1 和ugt85c2的基因表达框整合至sap155b位点,将启动子Pgal1与fpps的基因表达框整合至1021b位点。
将基因整合框中的DNA片段转化至酿酒酵母S.cerevisiae CEN PK2-1C MATa;ura3-52;trp1-289;leu2-3,112;his3Δ1;MAL2-8C;SUC2感受态细胞,挑取菌落PCR正确的转化子进行测序验证,最终获得具有甜茶苷合成通路的重组酿酒酵母菌株C1。
实施例2异戊烯基双磷酸盐-异构酶基因idi和羟基甲基戊二酰-CoA还原酶基因hmg1的强化
甜茶苷合成属于次级代谢,前体积累较少,为提高前体的合成,增加甲羟戊酸途径中的关键限速酶基因idi(核苷酸序列如SEQ ID NO.11所示)的拷贝数;切除羟基甲基戊二酰-CoA还原酶基因hmg1(核苷酸序列如SEQ ID NO.12所示)的N端内质网定位信号肽获得thmg1(核苷酸序列如SEQ ID NO.13),增加thmg1的拷贝数。
具体步骤为:
将启动子Pgal1/10与thmg1和idi的基因表达框整合至308a位点,得到重组酿酒酵母菌株C2。
实施例3过表达INO2
使用Ppgk1启动子(核苷酸序列如SEQ ID NO.15所示)与INO2基因 (核苷酸序列如SEQ ID NO.14所示)表达框替换C2菌株基因上的INO2基因与启动子序列,得到重组酿酒酵母菌株C3。
实施例4外排泵的鉴定及强化
根据AlphaFold预测酿酒酵母质膜上外排泵蛋白结构,通过与甜茶苷进行分子对接,结果如图2所示,初步筛选出甜茶苷的外排泵主要包含于ABC 外排泵家族。
选择五种不同类型的ABC外排泵抑制剂(利血平、羰基氰化物间氯苯腙、地塞米松、taniqudar和Phe-Arg-β-naphthylamide dihydrochloride)对重组酿酒酵母菌株C3进行抑制,结果如图3所示。结果发现利血平和CCCP 对甜茶苷外排具有明显的抑制作用,说明ABC外排泵在酿酒酵母对甜茶苷的外排中起非常重要的作用。
随后,敲除酿酒酵母质膜上的ABC外排泵pdr11、yor1、pdr12、pdr1、 pdr15、snq2、pdr10和pdr5,结果见图4。发现YOR1,PDR11和PDR12 敲除后,甜茶苷的产量降低至1倍以上,PDR1和PDR15敲除后甜茶苷的产量也有一定程度的下降,而其余外排泵无明显影响。
分别过表达以上三个外排泵YOR1(核苷酸序列如SEQ ID NO.1所示),PDR11(核苷酸序列如SEQ ID NO.2所示)和PDR12(核苷酸序列如SEQ ID NO.3所示),分别得到重组酿酒酵母菌株C4、C5和C6,发酵108h后甜茶苷生产情况及生长OD情况见图5和图6。结果显示,PDR11是甜茶苷的主要外排泵,PDR11过表达后甜茶苷的产量从67mg/L提升至155mg/L(图5),细胞形态恢复正常,生长OD明显提高(图6)。
实施例5重组酿酒酵母发酵生产甜茶苷
具体步骤如下:
将重组酿酒酵母菌株C1、C2、C3、C4、C5和C6划线与SD平板(添加尿嘧啶50mg/L),30℃下培养直至长出大量菌落。接种一环单菌落至种子培养基,30℃下220rpm培养18至20h至细胞生长对数前期。
按起始3%的接种量将种子培养液接种至发酵培养基中,30℃220rpm 培养108h。每隔12h取一次菌液,测量OD600与葡萄糖剩余量,结果如图 8所示。108h停止培养,将菌液转至50mL离心管,常温6000rpm离心10 min。弃去培养基,用1mL水重悬菌体,加入0.1mm的玻璃珠进行均质研磨。研磨后的样品,8000rpm离心10min,取上清液经0.22μm的水系滤膜过滤后进行LC-MS分析,质谱定性分析结果(上)和色谱分析结果(下) 如图7。
重组酿酒酵母菌株C1、C2、C3、C4、C5和C6发酵108h后甜茶苷产量结果如表1所示,表达fpps、ks、ko、kah、ugt74g1和ugt85c2基因,敲除gal80基因,增加idi的拷贝数,增加thmg1的拷贝数,优化P450酶,过表达INO2,过表达ABC外排泵,菌株甜茶苷的产量最高达到155mg/L, OD600达到23.7(过表达PDR11前OD600为14.4)。
