Abstract
在表面活性剂存在下具有稳定性的新的胆固醇氧化酶与编码该新胆固醇氧化酶的基因。
Description
技术领域
本发明涉及表面活性剂存在下具有稳定性的一种新的胆固醇氧化酶以及编码这种新的胆固醇氧化酶的基因。
背景技术
胆固醇氧化酶是一种催化3β-羟类固醇与氧之间的反应从而形成相应的3-氧类固醇与过氧化氢的氧化酶。到目前为止它的研究与开发目的是将其应用于测定体液的胆固醇浓度(例如,JP-A-6-169765)、生产胆固醇衍生物(例如,JP-A-6-113883)、杀虫剂(例如,美国专利5,558,862)、去污剂(例如,WO 89/09813)等。
众所周知所述酶由诸如链霉菌属(例如,JP-A-62-285789(对应于EP-A-0560983))、短杆菌属(例如,JP-A-4-218367(对应于EP-A-0452112))、红球菌属(例如,JP-T-3-503487(对应于WO 90/05788))与假单胞菌属(例如,JP-A-6-189754)的许多属的微生物产生。
从洋葱伯克霍尔德菌(Burkholderia cepacia)ST-200(根据旧的分类标准属于假单胞菌属ST-200,于1998年2月4日保藏National Instituteof Bioscience and Human Technology(NIBH)、Ministry of InternationalTrade and Industry(1-3,Higashi 1-chome,Tsukuba-shi,Ibaraki,Japan),保藏号为FERM MP-6661)(例如,日本专利号3,241,712(对应于US-A-2003/153051))分离的胆固醇氧化酶的特征在于当胆固醇用作底物时与迄今已知的其他胆固醇氧化酶相比它的产物是不同的,它的反应机理是不同的,并且它具有较高的有机溶剂抗性和温度稳定性。因为来源于洋葱伯克霍尔德菌ST-200的胆固醇氧化酶的基因已经被克隆,所以可通过分泌或者细胞内的累积在不同的宿主中高水平生产重 组胆固醇氧化酶(例如,JP-A-2002-65271)。
在用于临床诊断的试剂中使用的酶所需的特性是在大多数情况下对对象的高反应性和特异性以及影响产物保存稳定性的热稳定性,但是在测定胆固醇的情况下,为了高特异性测定对象的目的,经常以高浓度表面活性剂开处方,因此除上述特性之外,与表面活性剂共存的保存稳定性对于所使用的酶同样非常需要。虽然来源于洋葱伯克霍尔德菌ST-200的胆固醇氧化酶具有上述的优良特性,但是这种酶在与表面活性剂共存的保存稳定性方面较差,因此难以将这种酶应用于胆固醇测定试剂。
在用于胆固醇测定系统的表面活性剂中,1-戊基磺酸盐、1-己基磺酸盐、1-庚基磺酸盐、1-辛基磺酸盐、聚氧乙烯烷基醚硫酸盐、十二烷基苯磺酸钠、胆酸盐(胆酸钠)、胆酸、脱氢胆酸盐、脱氧胆酸、脱氧胆酸钠、牛磺脱氧胆酸钠、N,N-双(3-D-葡糖酰氨基丙基(gluconamidopropyl))胆酰胺、N,N-双-3-D-葡糖酰氨基丙基胆酰胺、十二烷基苯磺酸钠、月桂酰肌氨酸等用作阴离子表面活性剂(例如,JP-A-8-116996,日本专利2,799,835(对应于JP-A-7-13607),JP-A-11-56395,JP-A-2000-60600(对应于EP-A-0964249),JP-A-2002-142799(对应于EP-A-1342792),日本专利3,529,081(对应于JP-A-10-232219),JP-A-10-84997(对应于EP-A-0821239)。此外正-氯化十二烷基三甲铵、氯化十六烷基吡啶鎓等用作阳离子表面活性剂(例如,JP-A-10-84997(对应于EP-A-0821239))。
聚氧乙烯烷基醚、聚氧乙烯烷基苯基醚、聚氧乙烯-聚氧丙烯缩合物、酰基聚氧乙烯山梨聚糖酯、烷基聚氧乙烯醚、正-十二烷基-β-右旋麦芽糖苷、蔗糖单月桂酸酯、聚氧乙烯月桂基醚、聚氧乙烯烷撑苯基醚、聚氧乙烯烷撑三苄基苯基醚、聚氧乙烯甘油p-t-辛基苯基醚、聚氧乙烯高级醇醚、聚氧乙烯脂肪酸酯、聚氧乙烯山梨聚糖脂肪酸酯、山梨聚糖脂肪酸酯、聚氧乙烯山梨糖醇脂肪酸酯、聚氧乙烯烷基胺、 甘油脂肪酸酯、n-辛基-β-右旋硫葡糖苷、十六烷基醚(C16)、月桂基醚(C12)、油基醚、二十二烷基醚(C20)、聚氧乙烯单月桂酸酯等作为非离子型表面活性剂使用(例如,日本专利2,799,835(对应于JP-A-7-13607),JP-A-11-56395,JP-A-2000-60600(对应于EP-A-0964249),JP-A-2002-142799(对应于EP-A-1342792),日本专利3,529,081(对应于JP-A-10-232219),JP-A-10-84997(对应于EP-A-0821239),JP-A-2000-325097,JP-A-2001-124780,JP-A-2000-116400,JP-A-9-299,JP-A-2001-346598,JP-A-9-224697,日本专利3,193,634(对应于JP-A-9-313200),JP-A-10-210999)。
此外,甜菜碱衍生物、烷基甜菜碱衍生物、咪唑甜菜碱衍生物、硫甜菜碱衍生物、氨基羧酸衍生物、咪唑啉衍生物、胺oxanoide衍生物、胆汁酸衍生物等用作两性表面活性剂(例如,JP-A-2000-60600(对应于EP-A-0964249),JP-A-10-84997(对应于EP-A-0821239),JP-A-2000-325097,JP-A-2001-124780)。

接下来,描述获得本发明的氧化酶与本发明的基因的方法。
本发明的氧化酶可以通过筛选来源于微生物、动物或者植物的酶 从自然界获得。此外,本发明的氧化酶也可以通过利用遗传工程技术、突变处理等修饰具有不同于本发明的酶的物理化学特性的胆固醇氧化酶(以下简称“具有不同特性的氧化酶”)来获得。根据本发明的具有不同特性的氧化酶,可以列举上面描述的传统已知的氧化酶,但是同样可以是通过筛选新获得的胆固醇氧化酶或者通过遗传工程技术进行修饰获得的胆固醇氧化酶。例如来源于洋葱伯克霍尔德菌ST-200(描述在日本专利3,241,712(对应于US-A-2003/153051)中与JP-A-2002-65271中的)等可以作为传统已知的氧化酶引用。上述胆固醇氧化酶本来是具有信号序列的分泌性蛋白质,但是也可通过阻断信号序列来使用或者可以通过除去信号序列在细胞内生成。
修饰具有不同特性氧化酶的物理化学特性的方法的实例包括通过对能够生产氧化酶的微生物施用紫外线、X-射线或者辐射,或者通过使诸如甲基磺酸乙酯、N-甲基-N’-硝基亚硝基胍或者亚硝酸的诱变剂与微生物接触获得能够产生本发明修饰的氧化酶的微生物并由所获得的微生物获得本发明的氧化酶的方法。
然而,概括而言,本发明的氧化酶可以利用遗传工程通过修饰编码具有不同特性的氧化酶的基因来获得。作为编码具有不同特性用于本发明的氧化酶的基因,可以使用任一编码胆固醇氧化酶的基因,条件是通过其的修饰可以获得本发明的氧化酶的基因。
为了获得编码具有不同特性,用于本发明的氧化酶的基因,使用通常所用的基因克隆方法。例如,通过诸如在Current Protocols inMolecular Biology(WILEY Interscience,1989)描述的通常方法从能够产生具有不同的特性的氧化酶的微生物细胞或者多种其他细胞中提取染色体DNA或者mRNA。此外利用mRNA作为模板可以合成cDNA。制备因此获得的染色体DNA或者cDNA的文库。然后,可以通过在根据上述具有不同的特性的氧化酶的氨基酸序列合成合适的探针DNA,并利用这个探针从染色体DNA或者cDNA文库筛选的目的基因的方法或者通 过根据上述氨基酸序列制备的合适的引物DNA,利用这些引物通过实施合适的聚合酶链式反应(PCR)诸如5’RACE,3’RACE扩增包含目的基因片段的DNA片段然后连接这些片段的方法获得包含目的基因的全长DNA。作为以这种方式获得的编码具有不同特性的氧化酶的基因的优选实例,可以列举来源于洋葱伯克霍尔德菌ST-200的胆固醇氧化酶基因(JP-A-2002-65271中描述的)等。从处理的观点看需要这些基因以常规方法与不同的载体连接,并且可以利用例如QIAGEN(由Qiagen生产)从包含编码来源于分离的洋葱伯克霍尔德菌ST-200具有不同的特性的氧化酶的基因的重组质粒pCox4DNA(在JP-A-2002-65271中描述)中提取和纯化来获得。在这方面,可用于本发明的载体DNA不限于上述的质粒载体DNA,也可以使用诸如质粒载体DNA、噬菌体载体DNA等的其它质粒载体DNA。具体而言,优选例如pBluescript II SK+(由STRATAGENE生产)等。
其次,本发明的氧化酶可以通过修饰由上述方法获得的编码具有不同特性的氧化酶的基因来获得。也就是说,根据本发明,通过修饰编码具有不同特性的氧化酶的基因,由该基因翻译的具有不同特性的氧化酶的氨基酸序列得以修饰。结果,获得了与修饰之前的具有不同特性的氧化酶不同,包括本发明的氧化酶在内具有不同特性的多种胆固醇氧化酶。
编码具有不同特性的氧化酶的用于修饰的基因没有特定限制,但是来源于洋葱伯克霍尔德菌ST-200编码具有不同特性的氧化酶的基因(JP-A-2002-65271,SEQ ID NO:3)等可以作为本发明的实施方案的实例。此外,为了在宿主生物体中表达该基因,以氨基酸残基未添加、缺失、取代和/或插入,或者添加、缺失、取代、和/或插入的方式修饰的核苷酸序列的基因同样可以作为实例。
作为修饰上述基因的方法,可以使用任一传统已知的方法,并且其实例包括使诸如羟胺或者亚硝酸的化学诱变剂与上述重组质粒 pCox4DNA(描述在JP-A-2002-65271中)接触的方法,诸如利用PCR方法随机转化的点突变方法,通常已知的利用市售的试剂盒产生定位取代或者缺失突变的定位诱变方法,以及其中选择性切割重组质粒DNA,从其中除去或者向其中田间所选择的寡聚核苷酸,然后进行连接,即寡核苷酸诱变的方法。随后,在上述处理之后利用脱盐柱,QIAGEN(由Qiagen生产)等纯化重组DNA来获得不同的重组DNA样品。在这种情况下,使用通过从pCox4DNA除去编码胆固醇氧化酶的氨基末端侧信号序列并作为代替向其添加编码起始甲硫氨酸的ATG制备的重组DNA或者通过用氨基末端侧-编码的核苷酸序列取代适于在诸如大肠杆菌的宿主生物中表达的序列制备的重组DNA是有效的。
例如,利用以这样的方式获得的多种重组体DNA,通过转化或者转导大肠杆菌K12,优选大肠杆菌JM109或者DH5α(两者均由TOYOBO生产)、XL-Blue(由Funakoshi生产)等,可以获得包含具有修饰的胆固醇氧化酶基因片段的不同种类的重组DNA的转化或者转导产物。而后,对转化体而言,例如从所获得的转化体(其中包括含有不同种类的突变胆固醇氧化酶基因的重组质粒DNA分子)中选择在表面活性剂存在下具有稳定性的本发明的目的转化体(本发明的氧化酶生产菌株)。

用这样的方式可以获得具有生产本发明的氧化酶能力的转化体。实例包括通过以上所述的修饰方法处理具有SEQ ID NO:1所示的氨基酸序列的来源于洋葱伯克霍尔德菌ST-200的胆固醇氧化酶所获得的包含SEQ ID NO:2所示的氨基酸序列的本发明的氧化酶,等。此外,如有必要,通过利用这种具有生产本发明的氧化酶能力的转化体通过以上所述修饰方法进一步重复本发明的基因修饰,同样可以获得具有对表面活性进一步提高的稳定性的本发明修饰的氧化酶以及具有生产该酶能力的转化体。也就是说,根据本发明,在SEQ ID NO:2或者5所示的氨基酸序列中至少一个氨基酸缺失、取代、添加和/或插入的氨基酸序列的胆固醇氧化酶、由与SEQ ID NO:2或者5所示的氨基酸序列具有80%或更高同源性的氨基酸序列组成的胆固醇氧化酶等同样包括在本发明的氧化酶之内。例如可以具体列举在后面的实施例中显示的本发明的氧化酶(R7)等。在R7中,SEQ ID NO:2所示的氨基酸序列中3个氨基酸残基被取代,并且它具有90%或更高的同源性。另外,作为由此获得的能够生产本发明氧化酶的转化体的实例,可以引用产生由SEQ IDNO:2所示的氨基酸序列组成并且在表面活性剂共存下具有80%的残留活性的本发明的氧化酶(R1)的大肠杆菌JM109(pNCP1)。
同样,以上所述本发明的氧化酶(R1)的基因(SEQ ID NO:6)可以作为本发明的基因的实例引用。包括含有编码SEQ ID NO:5的SEQ ID NO:6的基因的质粒pNCP1作为已经以保藏号FERM BP-10343在2005年5月27日保藏在International Patent Organism Depositary、National Institute ofAdvanced Industrial Science and Technology(独立行政法人产业技术综合研究所,特许生物保藏中心,日本,千叶)。另外,编码诸如由在SEQ IDNO:2或者5所示的氨基酸序列至少一个氨基酸缺失、取代、添加和/或插入的氨基酸序列组成的胆固醇氧化酶以及由与SEQ ID NO:2或者5所示的氨基酸序列具有80%或更高同源性的氨基酸序列组成的胆固醇氧化酶的本发明的胆固醇氧化酶的基因,以及诸如由严格条件下与SEQ IDNO:4或者6所示的核苷酸序列全长,与SEQ ID NO:4或者6所示的核苷酸序列中连续15个或更多碱基,或者与由其互补核苷酸序列组成 的DNA杂交的核苷酸序列组成的DNA,以及由与SEQ ID NO:4或者6所示的核苷酸序列全长或者与SEQ ID NO:4或者6所示的核苷酸序列中连续15个或更多碱基具有80%或更高同源性的核苷酸序列组成的DNA的编码本发明的胆固醇氧化酶的基因可作为本发明的基因的实例。“连续15个或更多碱基”的具体实例包括作为SEQ ID NO:6的部分序列的从4到186个碱基的核苷酸序列等。另外,其中SEQ ID NO:4从130到312位碱基的核苷酸序列被替换成SEQ ID NO:6从4到186位碱基的核苷酸序列的序列同样编码SEQ ID NO:2的氨基酸序列,因此其同样可以引用为由具有80%或更高同源性的核苷酸序列组成的DNA的实例。
下面,通过利用培养基培养能够产生本发明的氧化酶的微生物并从培养混合物收集胆固醇氧化酶来生成本发明的氧化酶。任一微生物都可用于生产本发明的氧化酶,条件是所述微生物能够生成本发明的氧化酶。实例包括以上述方式获得的能够生成本发明的氧化酶的转化体或者转导产物。例如,可以通过利用能够生成本发明氧化酶的转化体并优选属于埃希氏杆菌属来产生本发明的氧化酶。在培养上述微生物中,可以通过固体培养方法培养,然而更优选通过采用液体培养法进行培养。另外,通过向酵母抽提物、蛋白胨、肉汤、玉米浆、大豆或者麦饼(wheat cake)汁等的一种或多种氮源中添加磷酸二氢钾、磷酸氢二钾、硫酸镁、氯化铁、硫酸铁、硫酸锰等的一种或多种无机盐,或任选添加糖、维生素等来制备用于培养上述微生物的培养基。在这方面,最好将培养基的初始pH值从6调节到9。需要通过充气搅拌浸没培养、振荡培养、静止培养等在从20℃到42℃的温度下优选在约25℃培养10到40小时进行培养。培养完成后,可以利用常规的酶收集方式从培养混合物收集本发明的氧化酶。通过例如过滤或者离心的操作从培养基中分离细胞,然后冲洗。需要从这样的细胞收集本发明的氧化酶。在这种情况下,可以就这样使用细胞,但是优选通过利用诸如超声粉碎器、弗氏压碎器与Dynomill的多种破碎装置破碎细胞的方法、利用诸如溶菌酶的细胞壁溶解酶溶解细胞壁的方法,或者利用诸如TritonX-100的表面活性剂从细胞提取酶的方法从细胞收集本发明的氧化酶。

在此选择的显色的10个菌株中的每一种都在2ml的LB培养基(添加50μg的卡那霉素)进行液体-培养,并产生由质粒编码的经修饰的胆固醇氧化酶。在培养之后,将由此获得的培养液通过超声波发生器进行破碎并在8,000rpm离心5分钟,并且将由此获得的0.5ml粗酶提取物与0.5ml的含有0.2%牛血清白蛋白,补充有10%Emalgen 913的100mMMES-NaOH缓冲液(pH7.0)混合,并且使混合物在37℃过夜反应。通过测量这种反应液与2倍稀释的未处理的粗酶提取物的活性,计算残留的活性比率(反应液体的活性/未经处理粗酶提取物的活性)。以相同的方式培养、提取与热处理具有不同特性的修饰之前的氧化酶,测定其活性,并比较残留的活性比率从而获得残留的活性比率从40%提高到80%的经修饰的胆固醇氧化酶及产生其的3种大肠杆菌菌株。其中编码1种(R1)基因的质粒pNCP1在2005年5月27日以保藏号FERM BP-10343保藏在International Patent Organism Depositary、 National Institute of Advanced Industrial Science and Technology Science and TechnologyScie
(3)突变发生区域的鉴定
回收携带经修饰的胆固醇氧化酶基因的质粒,利用CEQ2000XLDNA分析系统(Beckman Coulter生产)来测定核苷酸序列,并且在此基础上鉴定经修饰的氨基酸残基。
结果发现,如SEQ ID NO:2所示,在本发明的氧化酶(R1)的情况下,SEQ ID NO:1所示的氨基酸序列中175位的天冬氨酸被天门冬酰胺取代。其对应于SEQ ID NO:5中的133位。以相同的方式,在本发明另一个氧化酶(R7)的情况下,发现SEQ ID NO:1所示的氨基酸序列中173位的脯氨酸被亮氨酸取代,220位的天冬氨酸被谷氨酸取代。此外,这些突变区域对应于SEQ ID NO:5中的131位和178位。
(4)突变点的分离与组合尝试将这些突变点的每一个独立地引入。也就是说,利用pNCOP DNA,SEQ ID NO:17和18的序列(以这样方式设计,用天门冬酰胺代替位于SEQ ID NO:5中133位的天冬氨酸)作为引物以及KOD plus聚合酶(TOYOBO生产)进行PCR,通过琼脂糖凝胶电泳证实对应于该质粒全长的DNA片段的扩增,用限制性内切酶(作用于甲基化DNA;由Daiichi Pure Chemicals生产)处理该片段。接着转化入大肠杆菌JM109中,然后利用补充有卡那霉素的LB琼脂培养基选择转化体。用含有卡那霉素的液体培养基培养生长的克隆以回收携带胆固醇氧化酶基因的质粒,并且测定其核苷酸序列来证实所需的突变已被引入。通过相同的方法利用在131位的SEQ ID NO:19和20,和在178位的SEQ ID NO:21和22还可以获得SEQ ID NO:5的131位(脯氨酸被亮氨酸代替)和178位(天冬氨酸被谷氨酸代替)的位点-特异性突变的胆固醇氧化酶基因。此外,利用携带如此获得的位点-特异性突变的胆固醇氧化酶基因的质粒作为模板可以获得双突变的胆固醇氧化酶基因。在这种情况下,因为位于131位和133位的突变位点彼此邻近,可以用SEQ ID NO:23和24来进行操作。就可以进一步携带三突变的胆固醇氧化酶基因的质粒。
(5)突变点以及表面活性剂抗性
将上述获得的携带含有具有不同突变点的突变型胆固醇氧化酶基因的质粒的任一大肠杆菌JM109菌株培养在10ml补充有1.0mM IPTG的LB-卡那霉素培养基中,30℃培养24小时,然后将由此获得的培养基在8,000rpm离心5分钟以收集细胞,然后将所述细胞悬浮于1ml的20mM磷酸钾缓冲液中(pH7.0)。尔后,用超声波发生器破碎这些细胞并在10,000rpm离心10分钟回收上清液。将每一200μl的这些粗酶提取物与补充有2%Emalgen 913的含有0.2%小牛血清白蛋白的200μl 100mMMES-NaOH缓冲液(pH7.0)混合,在30℃保存混合物7天,与没有实施表面活性剂处理的粗酶提取物30℃保存7天的情况比较(表1)残留的酶活性比率。

此外,在对Emalgen 913观察到稳定效应的突变型胆固醇氧化酶上检验对其他表面活性剂(Emalgen 120,Emal 20C和Emal 20CM)的保存稳定性。在与上述试验相同的条件下通过将200μl的粗酶提取物与补充有2%的每种表面活性剂的含有0.2%小牛血清白蛋白的200μl的100mM MES-NaOH缓冲液(pH7.0)混合,并且使混合物在30℃保存3天(表2)

(C)本发明中氧化酶的产生及其理化特性
将由此获得的可以产生本发明氧化酶(R1)的转化体大肠杆菌JM109(pNCP1)接种到含有1mM IPTG的10升LB-卡那霉素培养基中,以11/分的通风,600rpm搅拌,利用发酵罐30℃培养24小时。将由此获得的10升培养基在7,000rpm离心10分钟收集细胞,然后将所述细胞悬浮于1升的20mM磷酸钾缓冲液(pH7.0)中。然后,用超声波发生器破碎细胞并于10,000rpm离心10分钟回收上清液作为粗酶液体。将该粗酶液体在60℃热处理30分钟,用20mM磷酸钾缓冲液(pH7.0)稀释10倍然后在10,000rpm离心10分钟回收上清液。在含有5mM EDTA的20mMTris-HCl缓冲液(pH8.8)中利用超滤膜AIP-2013(Asahi Chemical Industry生产)进行透析将上清液浓缩至500ml。然后,将混合物悬浮于用含有5mM EDTA的20mM Tris-HCl缓冲液(pH8.8)平衡的200mM的QAE-Sephadex A-50中,并回收通过用含有5mM EDTA的20mMTris-HCl缓冲液(pH8.8))洗涤残渣所获得的滤液和洗液作为活性级分。由此回收的本发明的氧化酶(R1)的比活性是4.0U/A280。
