Abstract
本发明涉及L‑赖氨酸生产能力得到提高的谷氨酸棒状杆菌突变株及利用其的L‑赖氨酸的生产方法，上述突变株通过使编码天冬氨酸半醛脱氢酶的基因的表达增加或增强，从而与亲本菌株相比，可以提高L‑赖氨酸的生产收率。
Description
技术领域
本发明涉及L-赖氨酸生产能力得到提高的谷氨酸棒状杆菌突变株及利用其的L-赖氨酸的生产方法。
背景技术
L-赖氨酸是人体或动物体内不能合成的必要氨基酸，必须从外部供给，一般情况下，是通过利用了细菌或酵母之类的微生物的发酵而生产的。L-赖氨酸的生产可以利用自然状态下获得的野生型菌株或者以提高其L-赖氨酸生产能力的方式转变的突变株。近年来，为了改善L-赖氨酸的生产效率，以多用于L-氨基酸和其它有用物质的生产的大肠杆菌、棒状杆菌等微生物为对象，适用基因重组技术，从而开发了具有优异的L-赖氨酸生产能力的各种重组菌株或突变株及利用其的L-赖氨酸生产方法。
根据韩国授权专利第10-0838038号和第10-2139806号，通过变更对包含与L-赖氨酸生产有关的酶的蛋白质进行编码的基因的碱基序列或氨基酸序列来增加该基因的表达或者剔除不必要的基因，从而可以提高L-赖氨酸生产能力。此外，在韩国公开专利第10-2020-0026881号中公开了为了增加对参与L-赖氨酸生产的酶进行编码的基因的表达而将基因的现有启动子变更为具有强活性的启动子的方法。
如上所述，开发了增加L-赖氨酸生产能力的各种方法，但与L-赖氨酸生产直接或间接相关的酶、转录因子、运输蛋白质等蛋白质的种类达到数十余种，因此关于根据这样的蛋白质的活性变化的L-赖氨酸生产能力是否增加，事实上仍需要大量的研究。

为了增强参与赖氨酸生物合成途径的天冬氨酸半醛脱氢酶的活性，增加赖氨酸生产率，在菌株中导入天冬氨酸半醛脱氢酶的增强。在本实施例中利用的方法，为了增加编码天冬氨酸半醛脱氢酶的asd基因的表达，对asd基因诱导了特异性突变。将asd基因的氨基酸序列中第35氨基酸由丙氨酸置换为甘氨酸，将第39氨基酸由丝氨酸置换为谷氨酸，将第78氨基酸由丙氨酸置换为缬氨酸，在谷氨酸棒状杆菌基因组上，以包含asd基因第35、第39、第78氨基酸的部分为中心，用PCR扩增左臂1000bp部分和右臂1785bp部分，通过重叠PCR(overlap PCR)方法连接后，克隆到作为重组载体的pCGI(参考文献[Kim et al.,Journalof Microbiological Methods 84(2011)128-130])中。将上述质粒命名为pCGI(asdA35G/S39E/A78V)(参考图1)。为了制作上述质粒，使用了下述表1的引物扩增各自的基因片段。
【表1】
利用以上的引物并在以下的条件下实施PCR。利用热循环仪(Thermocycler)(TP600，TAKARA BIO Inc.，日本)，在添加有各个三磷酸脱氧核苷酸(dATP、dCTP、dGTP、dTTP)100μM的反应液中，将1pM的寡核苷酸、10ng的谷氨酸棒状杆菌DS1菌株的染色体DNA用作模板(template)，在1单位的pfu-X DNA聚合酶混合物(Solgent)的存在下，实施了30周期(cycle)。PCR实施条件是在(i)变性(denaturation)步骤：在94℃30秒，(ii)退火(annealing)步骤：在58℃30秒，以及(iii)延伸(extension)步骤：在72℃1～2分钟(每1kb赋予2分钟的聚合时间)的条件下实施的。

作为上述方法中共同进行的过程，该基因的扩增是由谷氨酸棒状杆菌ATCC 13032的基因组DNA用PCR方法进行扩增的，根据策略，通过自组装克隆(self-assembledcloning)方法插入到pCGI载体中，并在E.coli DH5a中选择。染色体的基因碱基置换(Chromosomal base substitution)是分别扩增各个片段的基因，用层叠PCR制造了目标DNA片段。在基因操作时，作为PCR扩增酶，利用了Ex Taq聚合酶(Takara)、Pfu聚合酶(Solgent)，各种限制酶和DNA修饰酶使用了NEB制品，根据供给的缓冲液和方案进行了使用。
1-2.突变株的制造
利用上述pCGI(asd A35G/S39E/A78V)载体制造了作为突变菌株的DS4菌株。以上述载体的最终浓度成为1μg/μl以上的方式准备，对谷氨酸棒状杆菌DS1菌株使用电穿孔法(参考文献[Tauch et al.,FEMS Microbiology letters 123(1994)343-347])而诱导了1次重组。这时，将电穿孔的菌株涂抹在含有20μg/μl的卡那霉素的CM-琼脂平板上，分离菌落后，通过PCR和碱基序列分析确认了是否正确插入到了基因组的诱导位置。为了将这样分离的菌株再次诱导2次重组，接种在含有链霉素(streptomycine)的CM-琼脂液体培养基中，培养一夜以上后，涂抹在含有相同浓度的链霉素的琼脂培养基中，分离菌落。在最终分离的菌落中确认了是否存在对卡那霉素的耐性后，通过碱基序列分析确认了在没有抗生素耐性的菌株中是否向asd基因导入了突变(参考文献[Schafer et al.,Gene 145(1994)69-73])。最终，获得了导入有突变asd基因的谷氨酸棒状杆菌突变株(DS4)。
实施例2.谷氨酸棒状杆菌突变株的制造
将asd基因的氨基酸序列中第35氨基酸由丙氨酸置换为甘氨酸，将第38氨基酸由精氨酸置换为亮氨酸，将第39氨基酸由丝氨酸置换为谷氨酸，将第78氨基酸由丙氨酸置换为缬氨酸，除此以外，通过与实施例1相同的方法制造了谷氨酸棒状杆菌突变株。
在这里，为了制作质粒，使用了上述表1的引物扩增各个基因片段，利用制作的质粒pCGI(asd A35G/R38L/S39E/A78V)载体(参考图2)而制造了作为突变菌株的DS4-1菌株。最终，获得了导入有突变asd基因的谷氨酸棒状杆菌突变株(DS4-1)。
实验例1.突变株的L-赖氨酸生产率比较
将亲本菌株谷氨酸棒状杆菌DS1菌株和实施例1和2中制造的作为生产赖氨酸的突变株的DS4和DS4-1菌株的L-赖氨酸生产率进行了比较。
在含有10ml的具有下述表2所示的组成的赖氨酸培养基的100ml的烧瓶中，分别接种各自的菌株，在30℃以180rpm的条件震荡培养48小时。培养结束后，赖氨酸分析用HPLC(岛津，日本)测定了L-赖氨酸的生产量，将其结果示于表3。
【表2】
| 组成 | 含量(1L蒸馏水基准) |
| 葡萄糖(Glucose) | 100g |
| 硫酸铵(Ammonium sulfate) | 55g |
| KH<sub>2</sub>PO<sub>4</sub> | 1.1g |
| MgSO<sub>4</sub>·H<sub>2</sub>O | 1.2g |
| MnSO<sub>4</sub>·H<sub>2</sub>O | 180mg |
| FeSO<sub>4</sub>·H<sub>2</sub>O | 180mg |
| 硫胺素(Thiamine)·HCl | 9mg |
| 生物素(Biotin) | 1.8mg |
| CaCO<sub>3</sub> | 5％ |
| pH | 7.0 |
【表3】
| 菌株 | OD610 | L-赖氨酸(g/L) | 每单位菌体的L-赖氨酸生产量(g/gDCW) |
| 亲本菌株(DS1) | 22 | 64.8 | 7.0 |
| 突变株(DS4) | 22.2 | 71.9 | 7.7 |
| 突变株(DS4-1) | 21.6 | 67.4 | 7.4 |
如上述表3所示的那样，确认了在谷氨酸棒状杆菌突变株DS4和DS4-1中，为了增强赖氨酸生物合成途径，asd基因的氨基酸序列的特定位置(第35、第39和第78氨基酸，或者第35、第38、第39和第78氨基酸)被置换为最佳的碱基序列，与亲本菌株谷氨酸棒状杆菌DS1菌株相比，L-赖氨酸的生产率分别增加约10.0％、5.7％。通过这样的结果，可知asd基因的表达增强使赖氨酸前体的供给增强，从而提高了菌株的L-赖氨酸生产能力。
到目前为止，对本发明围绕其优选实施例进行了研究。本发明所属技术领域的技术人员可以理解本发明在不脱离本发明的本质性的特性的范围内可以以变形的形态实现。因此，公开的实施例应从说明性的角度进行考虑而不是从限制性的角度进行考虑。本发明的范围显示在权利要求书中而不是上述的说明中，并且应被解释为在与其等同范围内的所有的差异包括在本发明中。
