Description
技术领域
本发明属于微生物工程技术领域,具体地说,涉及用于发酵生产1,5-戊二胺的重组DNA、菌株及其应用。
背景技术
通过DNA重组技术改造具有生产L-赖氨酸能力的棒杆菌属和埃希杆菌属的细菌,现已实现工业化生产。这些细菌的L-赖氨酸生产率的提高是通过过表达L-赖氨酸合成途径的相关基因和反馈抑制脱敏的相关基因,或者从葡萄糖代谢开始的能量供应途径的强化而实现的。赖氨酸脱羧酶可以将L-赖氨酸脱去一个羧基生成1,5-戊二胺(尸胺)和CO2。例如,在大肠杆菌(E.coli)中,尸胺是通过两种赖氨酸脱羧酶多肽CadA和LdcC直接从L-赖氨酸生物合成的。
目前,1,5-戊二胺的生物合成主要利用两种策略进行:发酵生产或体外酶催化。在L-赖氨酸的发酵生产路径中,将赖氨酸脱羧酶(通常为CadA或LdcC),添加至产赖氨酸的微生物(例如谷氨酸棒杆菌和大肠杆菌)中,以便将赖氨酸生物合成途径延长至1,5-戊二胺生物合成途径。或者,对于体外酶催化,可以将细菌工程化或诱导以产生赖氨酸脱羧酶(通常为CadA或LdcC),然后其可用于通过脱羧作用将赖氨酸转化为1,5-戊二胺。1,5-戊二胺的用途相当广泛,例如可以与二元酸进行聚合反应合成新型尼龙,在工业生产中具有很高的应用价值。
但是,目前L-赖氨酸延长发酵生产1,5-戊二胺的路径中,1,5-戊二胺产量有限且收率较低。因此,亟需开发一种具有较高收率的生产尸胺的方法。
发明内容
本发明的目的是提供L-赖氨酸透性酶基因在微生物发酵生产1,5-戊二胺中的应用。

实施例1诱变获得的L-赖氨酸生产水平提高的突变株
从大肠杆菌MG1655(E.coli MG1655 K12,购自北京天恩泽基因科技有限公司)出发,通过ARTP物理诱变的方法,以及L-赖氨酸类似物添加平板进行筛选。
接种MG1655菌株至50mL的LB培养基,待菌体浓度到OD600=0.6时,收集菌体。将菌体转移至ARTP仪器(无锡源清天木生物科技有限公司),选取70秒进行诱变处理(致死率达到98%),收集诱变后的菌体,稀释102和103倍后,全部涂板M9培养基(其中培养基中添加4mg/L的L-赖氨酸类似物AEC)。在未添加AEC(5-(2-氨基乙基)-L-半胱氨酸)的平板上分别涂布未诱变菌(稀释105倍的菌液),以及诱变处理后的菌体(稀释103倍的菌液)。37℃培养两天后,共获得L-赖氨酸类似物耐受能力提高的菌株36株。挑取单菌落至30μL无菌生理盐水中,从筛选平板上蘸取菌体获得浑浊的菌液。取3μL划线至不同浓度的AEC平板进行复筛。通过使用不断增加浓度的L-赖氨酸类似物的添加平板继续重复筛选。最后确认M11菌株耐受能力最强。
从新突变株M11出发,通过ARTP物理诱变和高浓度L-赖氨酸类似物添加平板进行筛选,共获得24株新的突变菌株。将获得的24个新突变株和出发株M11,分别接种于不含抗生素的5ml种子培养基[(含有4%葡萄糖,0.1% KH2PO4,0.1% MgSO4,1.6%(NH4)2SO4,0.001% FeSO4,0.001% MnSO4,0.2%酵母提取物(购自英格兰OXOID LTD.),0.01%L-苏氨酸,0.005%L-异亮氨酸)]进行培养,37℃、225rpm过夜。第二天,每个菌株再分别转接至50ml新鲜的含有30g/L葡萄糖、0.7%Ca(HCO3)2和100μg/mL氨苄青霉素的发酵培养基中,于37℃、170rpm继续培养72h,利用核磁检测并计算各培养基中的赖氨酸的含量(表1)。

注:d25表示发酵液稀释25倍之后的测定结果。
如表1所示,发酵72h后,突变株M11-A3的赖氨酸的产量为3.57g/kg,相比于出发株M11的L-赖氨酸产量提升26%,且突变株与对照相比生长无显著差异。为提高筛选条件,将发酵时间缩短为48h。三次重复发酵出发株和该突变株,确认突变株M11-A3的产量为3.00g/kg,相对L-赖氨酸产量提升维持在24~26%。M11-A3菌株保藏于武汉大学中国典型培养物保藏中心(CCTCC),保藏编号为CCTCC NO:M 2018456。
实施例2构建表达载体pUC18-plac-cadA、pUC18-plac-ldcC、pUC18-plac-cadA-plac-lysP和pUC18-plac-ldcC-plac-lysP
首先,构建重组表达质粒pUC18-plac-cadA和pUC18-plac-ldcC。根据多片段一步法克隆试剂盒(购自南京诺唯赞生物科技有限公司)产品说明书设计引物,在plac序列的左侧引入与pUC18载体HindIII单酶切后上游重合20~30bp的DNA序列(SEQ ID NO:3)获得引物plac-F(SEQ ID NO:4)。在cadA基因序列的两端引入与plac序列及载体HindIII单酶切后下游重合20~30bp的DNA序列(SEQ ID NO:6)和(SEQ ID NO:7)获得引物对cadA-F/R(SEQID NO:8和9)。在ldcC基因序列的两端引入与plac序列及载体HindIII单酶切后下游重合20~30bp的DNA序列(SEQ ID NO:10)和(SEQ ID NO:11)获得引物对ldcC-F/R(SEQ ID NO:12和13)。以pUC18质粒DNA作为模板,使用引物对plac-F/R SEQ ID NO:4)和(SEQ ID NO:5),通过PCR扩增获得plac片段(SEQ ID NO:14)。以MG1655的基因组DNA作为模板,分别使用引物对cadA-F/R和ldcC-F/R,通过PCR扩增获得cadA片段(SEQ ID NO:15)和ldcC片段(SEQ IDNO:16)。将plac、cadA片段、ldcC片段和HindIII单酶切后的pUC18载体进行切胶回收纯化,使用多片段一步法克隆试剂盒将plac、cadA(或ldcC)片段和载体进行重组。重组后的混合物分别转化至E.coli JM109(购自宝生物工程(大连)有限公司)感受态细胞中,在含有氨苄青霉素的LB平板上进行筛选,获得多个单菌落。通过菌落PCR和测序验证证实plac-cadA和plac-ldcC表达序列已分别插入到质粒载体pUC18的HindIII位点,得到正确的表达载体pUC18-plac-cadA和pUC18-plac-ldcC。
然后,构建重组表达质粒pUC18-plac-cadA-plac-lysP和pUC18-plac-ldcC-plac-lysP。根据多片段一步法克隆试剂盒(购自南京诺唯赞生物科技有限公司)产品说明书设计引物,在lysP基因序列的两端引入与pUC18-plac-cadA或pUC18-plac-ldcC载体SacI/XbaI双酶切后重合20~30bp的DNA序列(SEQ ID NO:17)和(SEQ ID NO:18),获得引物对lysP-F/R(SEQ ID NO:19和20)。以大肠杆菌MG1655基因组DNA作为模板,使用引物对lysP-F/R(SEQID NO:19和20),通过PCR扩增获得lysP基因片段(SEQ ID NO:21)。将lysP基因片段分别与SacI和XbaI酶切后的pUC18-plac-cadA和pUC18-plac-ldcC载体进行切胶回收纯化,使用多片段一步法克隆试剂盒将lysP基因片段分别与上述两个载体进行重组。重组后的混合物全部转化至E.coli JM109(购自宝生物工程(大连)有限公司)感受态细胞中,在含有氨苄青霉素的LB平板上进行筛选,获得多个单菌落。通过菌落PCR和测序验证证实lysP基因已插入到质粒载体pUC18-plac-cadA和pUC18-plac-ldcC的SacI和XbaI位点之间,得到正确的表达载体pUC18-plac-cadA-plac-lysP和pUC18-plac-ldcC-plac-lysP。
实施例3构建1,5-戊二胺生产菌株和生产1,5-戊二胺
首先,构建L-赖氨酸生产菌株:使用实施例1筛选获得的M11-A3突变株,制备感受态。将实施例2构建得到的表达载体pUC18-plac-cadA、pUC18-plac-ldcC、pUC18-plac-cadA-plac-lysP和pUC18-plac-ldcC-plac-lysP分别转入受体菌M11-A3突变株中。涂布在含有100μg/ml氨苄青霉素的LB抗性平板中进行筛选。挑取12个单菌落至添加有氨苄青霉素的600μl LB培养基中,37℃培养3h后,取1μl菌体作为模板进行PCR验证筛选正确的突变株,并甘油保种。
上述含有pUC18-plac-cadA、pUC18-plac-ldcC、pUC18-plac-cadA-plac-lysP和pUC18-plac-ldcC-plac-lysP质粒的突变株各选取3个转化子和出发株M11-A3,分别涂布于含有100μg/ml氨苄青霉素和不含抗生素的种子培养基(同实施例1)平板上进行筛选。进一步地,分别各挑取3个单克隆,利用5ml种子培养基进行培养,37℃、225rpm过夜。第二天,每个菌株再分别转接至50ml新鲜的含有30g/L葡萄糖、0.7%Ca(HCO3)2和100μg/mL氨苄青霉素的发酵培养基中于37℃、170rpm继续培养48h,利用核磁检测并计算各培养基中的戊二胺的含量(表2)。
表2核磁检测突变株与出发菌株相比的戊二胺产量及OD600
如表2所示,含有质粒pUC18-plac-cadA和pUC18-plac-cadA-plac-lysP的转化株的戊二胺的产量分别为1.47g/kg和2.07g/kg。两个转化株的L-赖氨酸转化率分别为82.5%和93.1%。含有质粒pUC18-plac-ldcC和pUC18-plac-ldcC-plac-lysP的转化株的戊二胺的产量分别为1.31g/kg和1.87g/kg,两个转化株的L-赖氨酸转化率分别为78.0%和91.5%,且转化株与对照相比生长无显著差异。由此分析,lysP促进胞外Lysine向细胞内的运送,lysP和cadA基因或ldcC基因同时过表达均能够加速L-赖氨酸高效转化为戊二胺,菌株M11-A3/pUC18-plac-cadA-plac-lysP和M11-A3/pUC18-plac-ldcC-plac-lysP可用于戊二胺的生产。
