Description
本申请是申请日为2007年3月23日、发明名称为“生产尸胺的方法”的中国专利申请200780006903.9(国际申请号PCT/EP2007/052783)的分案申请。
发明领域
本发明涉及生产尸胺的方法。更特别地,本发明涉及重组微生物的用途,所述重组微生物包含生产尸胺所必需的以去调节形式存在的DNA分子。
现有技术
JP2002223770公开了通过将赖氨酸脱羧基因和/或赖氨酸-尸胺反向转运蛋白基因引入赖氨酸生产微生物来生产尸胺的方法。JP2004222569公开了通过培养具有赖氨酸脱羧酶活性和高丝氨酸营养缺陷型的重组棒杆菌来生产尸胺。
发明简述
在一方面,本发明提供了通过构建重组微生物并培养所述微生物来生产尸胺的方法,所述重组微生物具有去调节的赖氨酸脱羧酶和至少一种去调节的基因,该基因选自那些在赖氨酸的生物合成途径中所必需的基因。在另一方面,本发明提供了用于生产聚酰胺的方法,其包括如上所述的用于生产尸胺的步骤,并将尸胺与二羧酸相反应。
发明详述
在接下来的说明书中,广泛地使用了大量术语。此处提供了定义来促进对发明的理解。
术语尸胺意味着1,5-二氨基戊烷。
启动子.指导结构基因转录产生mRNA的DNA序列。通常启动子定位于基因的5’区域,邻近结构基因的起始密码子。如果启动子是诱导型启动子,那么转录效率会响应于诱导试剂而提高。相反,如果启动子是组成型启动子,转录效率则不受诱导试剂调节。
增强子.启动子元件.增强子可增加特定基因转录成mRNA的效率,无论增强子相对于转录起始位点的距离或方向。
表达.表达是从结构基因生产多肽的过程。该过程涉及将基因转录成mRNA并将此mRNA翻译成多肽。
克隆载体.DNA分子,例如质粒、粘粒、噬菌粒、或噬菌体,其具有在宿主细胞中自主复制的能力,并可用来转化细胞用于基因操作。克隆载体通常含有一个或少数的限制性内切核酸酶识别位点,外源DNA序列可以确定的形式在不损失载体的必需生物功能的情况下插入这些位点,以及适合用于鉴定和筛选克隆载体转化过的细胞的标志基因。标志基因通常包括那些提供四环素抗性或氨苄青霉素抗性的基因。
表达载体.包含克隆的编码外源蛋白质的结构基因的DNA分子,所述DNA分子提供外源蛋白质在重组体宿主中的表达。通常,将克隆基因的表达置于特定调节序列例如启动子和增强子序列的控制下(即,有效连接)。启动子序列可为组成型的或诱导型的。
重组宿主.重组宿主可以是任何原核的或真核的细胞,其含有克隆载体或表达载体。该术语也意味着包括那些经遗传工程操作的在宿主细胞染色体或基因组中含有克隆基因的原核或真核细胞。合适宿主的例子见Sambrook等人,MOLECULARCLONING:ALABORATORYMANUAL,第二版,ColdSpringHarborLaboratory,ColdSpringHarbor,N.Y.(1989)[″Sambrook"]。
如此处所用的,基本纯的蛋白质意味着目的纯化蛋白是基本上无污染的细胞组分,如通过在聚丙烯酰胺-十二烷基硫酸钠凝胶电泳(SDS-PAGE)之后的单条带所证实的。术语“基本上纯的”进一步意味着描述某分子通过本领域技术人员所用的一种或多种纯度或均一性特征来表征是均一的。例如,基本上纯的赖氨酸脱羧酶在某些参数标准的实验偏差内将显示恒定的和可重复的特征,所述参数如下:分子量、色谱迁移、氨基酸组成、氨基酸序列、封闭的或未封闭的N末端、HPLC洗脱图谱、生物活性、和其它此类参数。然而,该术语并不意味着排除赖氨酸脱羧酶与其它化合物的人工的或合成的混合物。另外,该术语并不意味着排除分离自重组宿主的赖氨酸脱羧酶融合蛋白。
在第一方面,本发明提供了一种用于通过构建重组微生物并培养所述微生物来生产尸胺的方法,所述微生物具有去调节的赖氨酸脱羧酶基因和至少一种去调节的选自下列的基因:(i)包括天冬氨酸激酶、天冬氨酸半醛脱氢酶、二氢吡啶二羧酸合酶、二氢吡啶二羧酸还原酶、四氢吡啶二羧酸琥珀酰酶(succinylase)、琥珀酰-氨基-酮基庚二酸转氨酶、琥珀酰-二氨基-庚二酸脱琥珀酰酶、二氨基庚二酸表异构酶、二氨基庚二酸脱氢酶、精氨酰-tRNA合成酶、二氨基庚二酸脱羧酶、丙酮酸羧化酶、磷酸烯醇丙酮酸羧化酶、葡萄糖-6-磷酸脱氢酶、转酮醇酶、转醛醇酶、6-磷酸葡糖酸内酯酶、果糖1,6-二磷酸酶、高丝氨酸脱氢酶、烯醇丙酮酸磷酸羧激酶、琥珀酰辅酶A合成酶、甲基丙二酰辅酶A变位酶,如果天冬氨酸激酶作为基因(i)而去调节,则必须有除天冬氨酸激酶之外的另一种基因(i)被去调节。
本发明的方法描述了如此处所述的和/或以导致尸胺产生的方式培养的重组微生物,其优选地包括载体或基因(例如,野生型和/或突变型基因)。
术语“重组”微生物包括已经遗传改变、修饰或工程化(例如遗传工程化的)的微生物(例如,细菌、酵母细胞、真菌细胞等等),以便其展示与其所来源的天然存在的微生物相比改变的、修饰的或不同的基因型和/或表型(例如,当遗传修饰影响微生物的编码核酸序列时)。
术语“去调节的”包括基因产物的表达(例如,赖氨酸脱羧酶)处于低于或高于在微生物操作前或在未经操作的相当的微生物中所表达水平的表达水平。在一个实施方案中,微生物可经遗传操作(例如,遗传工程化的)来表达比微生物操作前所表达的水平或未经操作的相当微生物中的表达水平更低或更高水平的基因产物。遗传操作可包括但不限于,改变或修饰调节序列或与特定基因的表达相关的位点(例如,通过除去强启动子,诱导型启动子或多重启动子)、修饰特定基因的染色体位置、改变与特定基因例如核糖体结合位点或转录终止子邻近的核酸序列、减少特定基因的拷贝数量、修饰涉及特定基因的转录和/或特定基因产物的翻译的蛋白质(例如,调节蛋白质、抑制子、增强子、转录激活因子等等)、或本领域中惯用的去调节特定基因表达的其它常规方法(包括但不限于使用翻译核酸分子、或其它方法来敲除或阻断靶蛋白的表达)。
术语“去调节基因活性”例如去调节的赖氨酸脱羧酶,还意味着将基因活性例如赖氨酸脱羧酶活性引入微生物,所述微生物中各自基因活性例如脱羧酶活性在此前并未发现过,例如优选通过遗传工程的方法将一个或多个拷贝的异源基因例如赖氨酸脱羧酶基因引入微生物。
赖氨酸脱羧酶催化L-赖氨酸脱羧化为尸胺。该酶被分类为E.C.4.1.1.18。分离自大肠杆菌(Escherichiacoli)的具有赖氨酸脱羧酶活性的酶是cadA基因产物(KyotoEncyclopediaofGenesandGenomes,Entryb4131)和ldcC基因产物(KyotoEncyclopediaofGenesandGenomes,EntryJW0181)。
SEQIDNO:1公开了大肠杆菌cadA的氨基酸序列,SEQIDNO:2公开了大肠杆菌ldcC的氨基酸序列。编码大肠杆菌赖氨酸脱羧酶基因的DNA分子可通过利用具有反向翻译自氨基酸序列SEQIDNO:1或2的多核苷酸的探针筛选cDNA或基因组文库来获得。
备选地,大肠杆菌赖氨酸脱羧酶基因可通过利用相互引发长寡核苷酸来合成DNA分子而获得。见例如,Ausubel等人,(eds.),CURRENTPROTOCOLSINMOLECULARBIOLOGY,8.2.8至8.2.13页(1990)[″Ausubel"].另外,见Wosnick等人.,Gene60:115(1987);和Ausubel等人(eds.),SHORTPROTOCOLSINMOLECULARBIOLOGY,第3版,8-8至8-9页(JohnWiley&Sons,Inc.1995)。利用聚合酶链式反应的确定技术提供了合成长度为至少2千碱基的DNA分子的可能。Adang等人,PlantMolec.Biol.21:1131(1993);Bambot等人,PCRMethodsandApplications2:266(1993);Dillon等人,"UseofthePolymeraseChainReactionfortheRapidConstructionofSyntheticGenes,"inMETHODSINMOLECULARBIOLOGY,Vol.15:PCRPROTOCOLS:CURRENTMETHODSANDAPPLICATIONS,White(ed.),263-268页,(HumanaPress,Inc.1993);Holowachuk等人,PCRMethodsAppl.4:299(1995)。
可生产与母酶相比含有保守氨基酸改变的大肠杆菌赖氨酸脱羧酶的变体。即,可获得含有SEQIDNO:1或2的一个或多个氨基酸替换的变体,其中用烷基氨基酸替换赖氨酸脱羧酶氨基酸序列中的烷基氨基酸,用芳香族氨基酸替换大肠杆菌赖氨酸脱羧酶氨基酸序列中的芳香族氨基酸,用含硫氨基酸替换大肠杆菌赖氨酸脱羧酶氨基酸序列中的含硫氨基酸,用羟基氨基酸替换大肠杆菌赖氨酸脱羧酶氨基酸序列中的含羟基氨基酸,用酸性氨基酸替换大肠杆菌赖氨酸脱羧酶氨基酸序列中的酸性氨基酸,用碱性氨基酸替换大肠杆菌赖氨酸脱羧酶氨基酸序列中的碱性氨基酸。
在共同的氨基酸中,例如“保守氨基酸替换”可列举为下列组之一中的氨基酸间的替换:(1)甘氨酸、丙氨酸、缬氨酸、亮氨酸和异亮氨酸,(2)苯丙氨酸、酪氨酸、和色氨酸,(3)半胱氨酸和甲硫氨酸,(4)丝氨酸和苏氨酸,(5)天冬氨酸和谷氨酸,(6)谷氨酰胺和天冬酰胺,和(7)赖氨酸、精氨酸和组氨酸。
大肠杆菌赖氨酸脱羧酶中的保守氨基酸改变可通过用核苷酸替换SEQIDNO:1或SEQIDNO:2中所述的核苷酸来引入。此类“保守氨基酸”变体可通过例如寡核苷酸定向诱变、接头扫描诱变、利用聚合酶链式反应的诱变等等得到。Ausubel等人,前述,8.0.3-8.5.9页;Ausubel等人(eds.),SHORTPROTOCOLSINMOLECULARBIOLOGY,第三版,8-10至8-22页(JohnWiley&Sons,Inc.1995)。通常还可见,McPherson(ed.),DIRECTEDMUTAGENESIS:APRACTICALAPPROACH,IRLPress(1991)。此类变体将L-赖氨酸转换为尸胺的能力可利用标准的酶活性测定法例如此处所述的测定法来测定。
根据本发明的优选的赖氨酸脱羧酶是来自大肠杆菌的赖氨酸脱羧酶及其等同基因,其与相应的“原始”基因产物有高达80%、优选地90%和最优选的95%和98%的序列同一性(基于氨基酸序列),并仍具有赖氨酸脱羧酶的生物学活性。这些等同基因可容易地由本领域已知的方法通过引入核苷酸替换、缺失或插入来构建。
本发明的另一优选的实施方案是大肠杆菌的赖氨酸脱羧酶(SEQIDNO:1和NO:2),通过应用谷氨酸棒杆菌(Corynebacteriumglutmicum)的密码子选择将其回译成DNA。这些赖氨酸脱羧酶多核苷酸序列对于棒杆菌属(Corynebacterium)的微生物特别是谷氨酸棒杆菌中赖氨酸脱羧酶的表达是有用的。
除了去调节的赖氨酸脱羧酶基因外,根据本发明的微生物必须具有至少一种选自组(i)的去调节的基因。组(i)是在赖氨酸的生物合成中发挥关键作用的一组基因,并由下列基因组成:天冬氨酸激酶、天冬氨酸半醛脱氢酶、二氢吡啶二羧酸合酶、二氢吡啶二羧酸还原酶、四氢吡啶二羧酸琥珀酰酶、琥珀酰-氨基-酮基庚二酸转氨酶、琥珀酰-二氨基-庚二酸脱琥珀酰酶、二氨基庚二酸表异构酶、二氨基庚二酸脱氢酶、精氨酰-tRNA合成酶、二氨基庚二酸脱羧酶、丙酮酸羧化酶、磷酸烯醇丙酮酸羧化酶、葡萄糖-6-磷酸脱氢酶、转酮醇酶、转醛醇酶、6-磷酸葡糖酸内酯酶、果糖1,6-二磷酸酶、高丝氨酸脱氢酶、烯醇丙酮酸磷酸羧激酶、琥珀酰辅酶A合成酶、甲基丙二酰辅酶A变位酶。
根据本发明的方法至少一种组(i)的基因必须被去调节。优选地根据本发明的微生物中多于一种组(i)的基因,例如两种、三种、四种、五种、六种、七种、八种、九种、十种基因被去调节。
组(i)的基因和基因产物是本领域中公知的。EP1108790公开了高丝氨酸脱氢酶和丙酮酸羧化酶基因中的突变,其对于重组棒杆菌在赖氨酸生产中的生产能力具有有益影响。WO0063388公开了天冬氨酸激酶基因中的突变,其对重组棒杆菌在赖氨酸生产上的生产能力具有有益影响。引用EP1108790和WO0063388作为与上述这些基因突变有关的参考。
下列的表中提及了各个基因的每一种基因/基因产物可能的去调节方式。在表的“去调节”列中所引用的文献和文件在此引用作为与基因去调节有关的参考。表中所提到的方式是各自基因去调节的优选实施方案。

实施例
1.赖氨酸脱羧酶基因的克隆
使用PCR引物WKJ12/WKJ13和WKJ35/WKJ34和大肠杆菌的染色体DNA作模板来分别扩增含有cadA和ldcC基因的DNA片段。纯化扩增的DNA片段、用限制酶消化,Asp718/NdeI用于cadA而XhoI/SpeI用于ldcC,并将其连接于用相同的限制酶消化的pClik5aMCS载体,从而分别得到的pClik5aMCScadA和pClik5aMCSldcC。
为增加ldcC基因的表达,将谷氨酸棒杆菌sodA启动子(Psod)在该基因的起始密码子之前替换。利用PCR引物从每个染色体DNA中扩增含有sodA启动子和ldcC基因编码区的DNA片段,其中WKJ31/OLD47用于Psod,而WKJ33/WKJ34用于ldcC,将所述DNA片段用作以WKJ31/WKJ34作引物的融合PCR的模板。纯化融合的PCR片段、用XhoI和SpeI消化片段、并将其插入pClik5aMCS载体的XhoI和SpeI剪切位点之间来构建pClik5aMCSPsod-ldcC。

2.构建尸胺生产菌株
为构建尸胺生产菌株,将赖氨酸生产菌LU11271用具有赖氨酸脱羧酶基因的重组质粒来转化,所述LU11271是通过将点突变T311I引入天冬氨酸激酶基因、复制二氨基庚二酸脱氢酶基因和破坏磷酸烯醇丙酮酸羧激酶基因而衍生于谷氨酸棒杆菌野生型菌株ATCC13032。
3.摇瓶培养中的尸胺生产
对重组菌株进行摇瓶实验来测试尸胺生产。使用与WO2005059139中所述的赖氨酸生产相同的培养基和条件。对对照宿主菌株和具有pClik5aMCS的重组菌株进行平行测试。将菌株在CM琼脂上在30°C下预培养过夜。将培养的细胞收获入含有1.5ml的0.9%NaCl的微型管,并在旋涡后通过610nm的吸光度来测定细胞浓度。为进行主培养,将悬浮细胞接种入10ml的生产培养基中达到1.5的初始OD值,所述培养基盛装在含有0.5g的CaCO3的高压灭菌的100ml锥形瓶中。主培养在旋转摇床(InforsAJ118,Bottmingen,瑞士)上,以200转/分在30°C下进行48-78小时。尸胺和赖氨酸的浓度利用HPLC(Agilent1100系列LC系统)来测定。
在培养了含有赖氨酸脱羧酶基因的所有重组菌株的发酵液中,积累了大量的尸胺。相反,观察到赖氨酸生产能力的显著下降。考虑到赖氨酸向尸胺的完全转化,必须产生与赖氨酸相同数量的尸胺分子。然而,所积累的尸胺的量却少于宿主菌株所生产的赖氨酸的量,另一方面,相当大量的副产物乙酰基尸胺伴随地积累,导致了糖产量的降低。
除了HPLC分析,还通过质谱方法鉴定了尸胺和乙酰基尸胺。
4.乙酰基尸胺形成酶的鉴定
为鉴定乙酰基尸胺形成酶,进行了蛋白质纯化。收获了培养在CM液体中的谷氨酸棒杆菌菌株ATCC13032或一些衍生物、将其洗涤并悬浮在0.5倍体积的标准缓冲液,所述缓冲液由50mMTris-HCl(pH7.8),0.02%Brij35,蛋白抑制剂混合物(Complete,Roche)和20%甘油组成。利用微流器(M-110EH,MicrofluidicsCo.)裂解细胞悬浮物后利用微量过滤器(MF42,Satorius)进行过滤。
通过使用QSepharose(Q琼脂糖)(AmershamBioscience,50x300mm,在10mMTris(pH7.5)缓冲液中的0.0-0.5MNaCl的线性梯度,10ml/min的流速)、PhenylSepharose(苯基琼脂糖)(AmershamBioscience,50x300mm,在10mMTris(pH7.5)缓冲液中的1.5-0.0M乙酸铵的线性梯度,10ml/min的流速)、Superdex(AmershamBioscience,26x600mm,10mMTris(pH7.5)缓冲液,4ml/min的流速)、Mono-Q(AmershamBioscience,5x50mm,在10mMTris(pH7.5)缓冲液中的0.0-0.5M-NaCl的线性梯度,1ml/min的流速)和Superose(AmershamBioscience,15x300mm,10mMTris(pH7.5)缓冲液,0.3ml/min的流速)一系列柱子来纯化滤液中的酶。整个纯化步骤中,对级分中的乙酰转移酶的酶活性和酶反应混合物中的乙酰基尸胺的存在进行监测。在下列条件下通过监测1ml的总体积中由于产生TNB(硫代硝基苯甲酸)而导致的412nm处吸收的增加来测定酶活性:10mMTris-HCl(pH7.8),0.1mMDTNB(5,5’-二硫代双-(2-硝基苯甲酸)),0.25mM乙酰辅酶A,5mM尸胺,酶溶液。
利用TNB的13.6mM-1xcm-1的摩尔消光系数来计算比活性。
将来自Superose柱子的含有酶活性的级分上样于SDS-PAGE凝胶。从考马斯染色凝胶切下后,用改良的胰蛋白酶(Roche,Mannheim)如Hermann等人所述(Electrophoresis(2001),22,1712-1723)消化蛋白点。在nano-HPLC分离肽(LCPackings,RP18柱,长度15cm,i.d.75μm)之后,在LCQadvantage(ThermoElectron)上利用MASCOT软件(Davidetal.(1999)Electrophoresis,20,3551-3567)进行了质谱鉴定。结果,鉴定出作为潜在的乙酰基尸胺形成酶的乙酰转移酶(Genebank检索号:NP600742)。
5.质粒构建和乙酰转移酶基因的破坏
为了进行所鉴定的编码乙酰转移酶的基因的染色体破坏,构建了重组质粒,其允许通过两次连续的同源重组事件的无标记操作。利用一套PCR引物(WKJ203/WKJ205用于上游而WKJ206/WKJ204用于下游)从谷氨酸棒杆菌染色体DNA扩增了含有基因的上游和下游区域的DNA片段,将所述片段用作模板利用PCR引物WKJ203/WKJ204进行融合PCR来制备除去了基因中间区域的融合片段。纯化了融合PCR的产物,用XhoI和SpeI进行消化,并将其插入用相同的限制酶消化的pClikintsacB载体,这使得序列在谷氨酸棒杆菌的基因组基因座处得以整合(Becker等人(2005),AppliedandEnvironmentalMicrobiology,71(12),p.8587-8596)。然后将质粒用于破坏乙酰转移酶基因的天然编码区域。所用的菌株是LU11271LdcC,其中ldcC基因被整合入染色体的bioD基因座上,且其同时产生尸胺和乙酰基尸胺。两次连续的重组事件(在上游和下游区域各有一次)是破坏基因中间序列所必需的。所破坏的突变体通过利用引物WKJ203/WKJ204的PCR和DNA杂交分析来确认。

6.对乙酰基尸胺形成和尸胺生产能力的影响
为分析乙酰转移酶基因的破坏对乙酰基尸胺形成和尸胺生产能力的影响,对破坏的突变体进行了摇瓶实验。使用了与尸胺生产相同的培养基和条件(同上)。破坏的突变体没有显示处乙酰基尸胺的积累。这表明只有所鉴定的乙酰转移酶负责乙酰基尸胺的形成。因此,通过破坏所述基因致使乙酰基尸胺形成的消除提高了尸胺生产能力。
