Description
技术领域
本发明涉及一种能够生产1,4-丁二醇的突变体微生物,以及使用该突变体微生物制备1,4-丁二醇的方法。
背景技术
可生物降解的聚合物已经被建议作为合成聚合物的替代品,合成聚合物是严重环境污染的重要原因之一。在目前正在开发的各种可生物降解的聚合物中,聚-β-羟基丁酸酯(poly-β-hydroxybutyrate)是各种微生物在营养不平衡状态下储存的一种可生物降解的聚合物,其具有优良的特性,如生物可降解性、水抗性、压电性和生物相容性。尤其是4-羟基丁酸酯,其是聚羟基链烷酸酯(PHA)的一个例子,具有聚酯样特性,并显示从结晶塑料到高弹性橡胶的特性的许多特性。因此,目前正在对微生物可生物降解的塑料进行大量研究。
此外,4-羟基丁酸酯可以很容易被转变成具有4个碳原子的各种化学制品,如1,4-丁二醇、γ-丁内酯(GBL)和THF。尤其是,1,4-丁二醇是一种以如聚合物、溶剂和精细化学制品中间体多种形式存在的重要的工业化学制品。虽然具有4个碳原子的大多数化学制品目前是从1,4-丁二醇、马来酐等等合成的,但是由于油价格的增加而导致的增加的生产成本,需要开发用于补偿和替代常规的化学生产方法的另一种方法。生物学方法已经被建议作为这种替代方法。
同时,琥珀酸(succinate),具有4个碳原子的二羧酸,是在厌氧条件下培养微生物时产生的一种有机酸。现在,多种微生物被用作生产琥珀酸的细胞,而且由于有效的发酵方法以及分离和纯化方法的发展,它的生产成本变得更低。还可以由琥珀酸生产4-羟基丁酸酯,而且具有4个碳原子的各种有机酸可以源自4-羟基丁酸酯。
PCT公开第WO 2005/052135号是公开了一种有效生产琥珀酸的方法的专利申请的一个例子,其中,腔细菌(Lumen bacterial)突变体在不产生其他有机酸的情况下生产高浓度的琥珀酸,和一种使用该突变体制备琥珀酸的方法。另外,韩国专利申请第10-2004-60149中公开了一种制备能够生产高浓度的琥珀酸的大肠杆菌突变体的方法,并且韩国专利申请第10-2005-0076301号、第10-2005-0076317号和第10-2005-0076348号中公开了一种使用新基因制备琥珀酸的方法。
如上面所解释的,迫切需要一种能够生产1,4-丁二醇的突变体和使用该突变体制备1,4-丁二醇的生物学方法,1,4-丁二醇是一种具有4个碳原子的工业上重要的化学制品。
发明内容
技术问题
本发明旨在提供一种能够高效生产1,4-丁二醇的突变体微生物,以及使用该突变体微生物制备1,4-丁二醇的方法。
技术方案
一个方面,提供了一种能够生产琥珀酸的微生物和使用该微生物制备1,4-丁二醇的方法,所述微生物优选为显示出高1,4-丁二醇产量的突变体,其中,引入或增强编码把琥珀酸转变成4-羟基丁酸酯的酶的基因和编码把4-羟基丁酸酯转变成1,4-丁二醇的酶的基因。
另一个方面,提供了SEQ ID NO:8或SEQ ID NO:9的丁基-辅酶A脱氢酶基因和具有该基因的重组载体,该基因将4-羟基丁基-辅酶A有效生产为1,4-丁二醇。
在下文中,将更详细地描述本发明。
作为使用能够生产琥珀酸的微生物制备1,4-丁二醇的努力的结果,本发明人通过在能够生产琥珀酸的微生物中诱导或增强与4-羟基丁酸酯生物合成相关的基因和/或与1,4-丁二醇生物合成相关的基因,开发了一种生产1,4-丁二醇的突变体微生物,并发现,该突变体微生物有效生产1,4-丁二醇。该发现导致了本发明。
这里使用的术语“增强”指与原始表达水平相比基因表达水平的增加。如果在突变之前微生物中没有待增强的基因,那么可以向该微生物中引入至少一个基因,然后增强。并且,如果在突变之前在微生物中有待增强的基因,可以通过如上所述的相同的方法向该微生物中引入至少一个基因,或者可以通过遗传工程技术对原来存在于微生物中的基因进行操作以增加基因表达。例如,当增强表达的基因存在于待突变的微生物中时,可以用更强的启动子代替用于操纵基因表达的原始启动子,从而增强基因表达。
能够生产琥珀酸的微生物可显示出高琥珀酸产量,该微生物优选为选自细菌、酵母和真菌中的一种,更特别地为细菌,例如,腔细菌(Lumen bacteria)、棒状杆菌(Corynebacterium species)、短杆菌(Brevibacterium species)和大肠杆菌(E.coli)。
所述腔细菌可具有失活的编码乳酸脱氢酶(ldhA)和丙酮酸-甲酸裂解酶(pfl)的基因,并在厌氧条件下在不产生其他有机酸的情况下高浓度生产琥珀酸。
这里使用的术语“失活”指由于突变基因没有被转录,或者转录的mRNA没有适当地被翻译成原始蛋白质。为了使基因失去活性,可通过丢失基因或改变基因的核酸序列来进行突变。
此外,所述腔细菌可具有失活的编码乳酸脱氢酶(ldhA)、丙酮酸-甲酸裂解酶(pfl)、磷酸转乙酰酶(pta)和乙酸激酶(ackA)的基因,并在厌氧条件下在基本上不生产其他有机酸的情况下高浓度生产琥珀酸。
做为选择,所述腔细菌可具有失活的编码乳酸脱氢酶(ldhA)、丙酮酸-甲酸裂解酶(pfl)和磷酸丙酮酸羧化酶(ppc)的基因,并在厌氧条件下在基本上不产生其他有机酸的情况下高浓度生产琥珀酸。
所述腔细菌可选自Mannheimia sp、放线杆菌(Actinobacillus sp.)和厌氧螺菌(Anaerobiospirillum sp.),但是本发明不局限于这些例子。Mannheimia sp.是优选的,而且Mannheimia succiniciproducens MBEL55E(KCTC 0769BP)、Mannheimia sp.LPK(KCTC 10558BP)、LPK4和LPK7(KCTC 10626BP)是更优选的。
所述大肠杆菌可具有失活的编码葡萄糖磷酸转移酶(ptsG)和丙酮酸激酶(pykA和pykF)的基因,并在厌氧条件下在基本上不产生其他有机酸的情况下高浓度生产琥珀酸。特别地,大肠杆菌突变体优选是在韩国专利公开第10-2006-0011345号中公开的W3110GFA。
在上述高浓度生产琥珀酸的微生物中,可以以PCT公开第WO 2005/052135号中公开的方法制备腔细菌。也就是说,使Mannheimia succiniciproducens 55E中的乳酸脱氢酶基因(ldhA)和丙酮酸-甲酸裂解酶基因(pfl)失活,从而构建突变株,也即Mannheimnia sp.LPK(KCTC 10558BP)。然后,在LPK株中,使磷酸转乙酰酶基因(pta)和乙酸激酶基因(ackA)的基因和磷酸丙酮酸羧化酶的基因(ppc)分别失活,从而构建突变株(Mannheimia sp.LPK7和LPK4),然后在厌氧条件下进行培养以高产量生产琥珀酸。
另外,在高浓度生产琥珀酸的微生物中,通过韩国专利公开第10-2006-0011345号中公开的方法构建大肠杆菌。也就是说,通过在用表达噬菌体red操纵子(exo-β-gam)的重组表达载体转化的W3110菌株中,使编码葡萄糖磷酸转移酶(ptsG)的基因和编码丙酮酸激酶(pykA和pykF)的两个基因失活,来产生突变体大肠杆菌菌株W3110GFA。然后,当在厌氧条件下培养突变体大肠杆菌菌株W3110GFA时,可以证实突变体的生产率大于母本菌株W3110的生产率。
把琥珀酸转变成4-羟基丁酸酯的酶的基因和与把琥珀酸半醛转变成琥珀酸相关的酶的基因可以来源于科氏梭菌(Clostridium kluyveri),而把4-羟基丁酸酯转变成1,4-丁二醇的酶的基因可来源于丙酮丁醇梭菌(Clostridium acetobutylicum)。虽然科氏梭菌和丙酮丁醇梭菌不生产4-羟基丁酸酯和1,4-丁二醇,但是在这些菌株中克隆的酶在生产4-羟基丁酸酯和1,4-丁二醇中发挥重要作用。
另外,把琥珀酸转变成4-羟基丁酸酯的酶的基因可选自编码琥珀酰辅酶A转移酶(Cat1)的基因、编码琥珀酸半醛脱氢酶(SucD)的基因、编码4-羟基丁酸脱氢酶(hbD)的基因、编码4-羟基丁酸脱氢酶(GHB)的基因。优选地,编码Cat1的基因具有SEQID NO:1的碱基序列,编码SucD的基因具有SEQ ID NO:2的碱基序列,编码4hbD的基因具有SEQ ID NO:3的碱基序列,以及编码GHB的基因具有SEQ ID NO:4的碱基序列。
例如,根据本发明的突变体微生物可以具有编码Cat1的基因、编码SucD的基因和编码4hbD的基因,或者编码Cat1的基因、编码SucD的基因和编码GHB的基因,但是本发明不局限于这些例子。
此外,琥珀酸的有效使用对实现本发明的目标是非常重要的,因此可以从高浓度生产琥珀酸的微生物重组大肠杆菌中除去与把琥珀酸半醛转变成琥珀酸相关的琥珀酸半醛脱氢酶(GabD)。因此,根据本发明的突变体微生物也可具有失活的与把琥珀酸半醛转变成琥珀酸相关的基因,其优选是编码琥珀酸GabD的基因。编码GabD的基因具有SEQ ID NO:10的碱基序列,但是本发明不局限于该序列。
同时,为了在微生物中有效转运琥珀酸,可以增强与琥珀酸的转运相关的C4-二羧酸转运蛋白(DctA)酶。因此,突变体微生物可另外具有编码与琥珀酸的转运相关的Dct4的基因,其被引入到突变体微生物中或被增强,而且编码Dct4的基因优选具有SEQ ID NO:11的碱基序列。
所述把4-羟基丁酸酯转变成1,4-丁二醇的酶的基因可以是编码4-羟基丁酸-辅酶A转移酶和使4-羟基丁酸-辅酶A还原的醇脱氢酶的基因,或者编码磷酸转丁酰酶、丁酰激酶和使4-羟基丁酸-辅酶A还原的醇脱氢酶的基因。
所述编码4-羟基丁酸-辅酶A转移酶的基因可以具有SEQ ID NO:5的碱基序列,其可以用磷酸转丁酰酶(ptb;SEQ ID NO:6)和丁酰激酶(BuK;SEQ ID NO:7)取代,以把4-羟基丁酸酯转变成4-羟基丁酸-辅酶A。
所述醇脱氢酶可以是来源于丙酮丁醇梭菌的丁基-辅酶A脱氢酶,而且编码丁基-辅酶A脱氢酶的基因优选具有SEQ ID NO:8或SEQ ID NO:9的碱基序列(CAP0035或CAP0162)。SEQ ID NO:8和SEQ ID NO:9的基因对于在根据本发明的突变体微生物中生产1,4-丁二醇是非常有用的。因此,本发明提供了一种编码丁基-辅酶A脱氢酶的基因和含有该基因的重组载体。
术语“载体”指含有与适于在合适的宿主中表达DNA的调控序列可操作连接的DNA序列的DNA构建体。在本发明中,载体可包括质粒载体、噬菌体载体、粘粒载体、酵母人工染色体(YAC)载体,而且优选质粒载体。例如,质粒载体可以具有这样的结构,其包括(a)用于有效复制以在一个宿主细胞中具有几百个拷贝的复制起点,(b)用于筛选用该质粒载体转化了的宿主细胞的抗生素抗性基因,和(c)其中能够插入外源DNA片段的限制性内切酶位点。即使没有适合的限制性内切酶位点,可以根据常规方法使用合成的寡核苷酸适体或接头,很容易地连接载体与外源DNA。
因此,本发明提供了一种能够生产琥珀酸的微生物,且优选显示高1,4-丁二醇产量的突变体微生物,其中,使编码GabD的基因失活,而且引入或增强编码Cat1的基因、编码SucD的基因、编码4hbD(或GHB)的基因、编码4-羟基丁酸-辅酶A转移酶的基因和编码丁基辅酶A脱氢酶的基因的全部。
此外,本发明提供了一种能够生产琥珀酸的微生物,且优选显示高1,4-丁二醇产量的突变体微生物,其中,引入或增强编码4-羟基丁酸-辅酶A转移酶的基因(或编码磷酸转丁酰酶的基因和编码丁酰激酶的基因)和编码丁基-辅酶A脱氢酶的基因,以及使用该微生物制备1,4-丁二醇的方法。
本发明进一步提供了一种制备1,4-丁二醇的方法,其包括在含有碳源的培养基中培养该突变体,并从所述培养物中获得1,4-丁二醇。
有益效果
如上面详细描述的,本发明提供了一种能够高浓度生产琥珀酸的微生物,且更优选地,一种显示高1,4-丁二醇产量的突变体以及使用该微生物制备1,4-丁二醇的生物学方法,1,4-丁二醇是一种具有4个碳原子的化学制品,其在化学工业中具有广泛的重要应用。

在下文中,将通过实施例更详细地描述本发明。本领域技术人员将清楚理解,提供实施例只是为了解释本发明,而不是为了限制它的范围。
同时,在本发明中,制备1,4-丁二醇的方法使用腔细菌(如突变体Mannheimiasp.LPK(KCTC 10558BP)、LPK7和LPK4,其具有来源于Mannheimia sp.菌株的失活基因并高浓度生产琥珀酸)、大肠杆菌和突变体大肠杆菌W3110GFA,本领域技术人员将清楚理解,可以使用另一种腔细菌菌株,通过产生高浓度生产琥珀酸的突变体,并引入和增强与生产1,4-丁二醇相关的基因来生产1,4-丁二醇。
另外,下面的实施例提供了具体的培养基和培养方法,本领域技术人员将清楚地理解,如文献(Lee等人,Bioprocess Biosyst.Eng.,26:63,2003;Lee等人,Appl.Microbiol.Biotechnol,58:663,2002;Lee等人,Biotechnol.Lett,25:111,2003;Lee等人,Appl.Microbiol.Biotechnol.54:23,2000;以及Lee等人,Biotechnol.Bioeng.,72:41,2001)中所公开的,这里使用的培养基可以不同于水解物(如乳清或玉米浆),或者可以使用不同的培养方法(如加料分批培养和连续培养)。

为了构建表达载体,把扩增的ptb和buk基因的操纵子插入到表达载体pTacLacI中,其用EcoRI/XbaI切割,从而获得pTacLacPtbBuk。用SspI切割载体pTacLacPtbBuk,以获得包括tac启动子、ptb和buk基因和转录终止子的基因片段,并把该基因片段插入到载体pBBR1MCS2(Kovach等人,Gene.166:175,1995)中,其用EcoRV切割,从而获得载体pMCS2TacPtbBuk。
实施例3:1,4-BDO的产生
载体pTacCAP162和pMCS2Tacptbbuk用大肠杆菌XL1-Blue通过电穿孔同时转化,然后铺板于含有100μg/ml氨苄青霉素和50μg/ml醌那霉素的LB平板上,并于37℃培养过夜。把培养的克隆接种到具有3ml LB液体培养基(包含100μg/ml氨苄青霉素)的15ml管(Falcon,USA)中,并以200rpm于37℃在振动孵育箱中生长过夜。将孵育的细胞接种到新鲜的LB液体培养基(含有100ml 2%葡萄糖和100μg/ml氨苄青霉素)中,然后以200rpm于37℃生长于振动孵育箱中。当OD600达到0.7时,以1mM的终浓度添加IPTG来诱导蛋白表达,并且将细胞培养过夜。
然后,离心培养物,并从其中除去上清液。然后,将细胞沉淀用MR培养基洗涤一次,重悬于包含50ml 2%葡萄糖和2%γ-羟基丁内酯和1mM IPTG的MR培养基中,并使用5%H2、5%CO2和余量N2的气体混合物起绒毛30分钟以建立厌氧条件。培养物以200rpm于37℃在振动孵育箱中生长过夜,并持续大约3天,然后离心培养物以获得上清液。获得的上清液浓缩两次,并用作GC分析样品用于分析,以证实1,4-丁二醇的产生。在下列条件下进行分析,且结果示于图3中。
柱:AT-Waw(0.53mm ID x 15ml,1.2um u.f.毛细管)
气体流速:柱(He):4.0ml/min
烘箱温度:初始值&时间:50℃,5min
编程速率:10℃/min
终值&时间:250℃,5min
喷射器温度:250℃
检测器温度:250℃
喷射器分流比:20/1
喷射器体积:1.0μl
如图3所示,证实产生了1,4-丁二醇。
虽然已经参考其某些实施例显示和描述了本发明,本领域技术人员将理解,可以多种形式和细节对其进行各种改变,而不背离如所附权利要求所限定的本发明的精神和范围。
