Abstract
通过修饰天然α-葡聚糖磷酸化酶获得的耐热化α-葡聚糖磷酸化酶;和制备所述耐热化α-葡聚糖磷酸化酶的方法。所述天然α-葡聚糖磷酸化酶来源于植物。与天然α-葡聚糖磷酸化酶比较,耐热化α-葡聚糖磷酸化酶在选自下组的至少一个位置具有不同的氨基酸残基:对应基序序列1L或1H的4-位的位置、对应基序序列2的4-位的位置和对应基序序列3L或3H的7-位的位置,并且在20mM柠檬酸盐缓冲液(pH6.7)中在60℃加热10分钟以后,所述耐热化α-葡聚糖磷酸化酶在37℃的酶活性是加热之前所述耐热化α-葡聚糖磷酸化酶在37℃的酶活性的20%或更多。
Description
技术领域
本发明涉及热稳定的α-葡聚糖磷酸化酶和编码所述热稳定α-葡聚糖磷酸化酶的基因。另外,本发明还涉及生产热稳定α-葡聚糖磷酸化酶的方法。
背景技术
α-葡聚糖磷酸化酶(以下也称GP)是例如用于合成葡萄糖-1-磷酸(以下也称G-1-P)和合成葡聚糖的一种酶。G-1-P例如用作医用抗菌药、抗肿瘤药(作为铂络合物)、治疗心脏病的药物(作为胺盐)或葡聚糖合成的底物。GP广泛分布于植物,例如分布在马铃薯的块茎;动物,例如兔肌肉;和微生物如酵母中。
其中,植物来源的GP是有用的,因为它通常具有合成高分子量葡聚糖的能力。
多种GP可用于生产G-1-P或葡聚糖,其中,马铃薯来源的GP用于很多情况中,因为容易获得较大量的该酶。
在使用GP工业生产G-1-P或葡聚糖中,有必要基本去除缘于GP污染的其它酶活性,尤其是磷酸酶活性和淀粉酶活性。当大量生产GP时,大肠杆菌(Escherichia coli)和枯草杆菌(Bacillus subtilis)是表达GP基因的理想宿主。然而,如图4和图5所示,大肠杆菌具有淀粉酶活性和磷酸酶活性,而枯草杆菌具有淀粉酶活性。然而,如图4和图5所示,由这些宿主表达的酶不能被55℃热处理灭活,但几乎能被60℃热处理完全灭活。因此,希望得到具有抗热性的植物来源GP,其活性甚至在60℃热处理后也不丧失。
作为参考,热处理前后多种细菌(大肠杆菌TG-1株、大肠杆菌BL21株和枯草杆菌ANA-1株)的细胞提取物中淀粉酶和磷酸酶活性的具体数值在下表1中给出。
(表1)
然而,能合成高分子量葡聚糖并具有耐热性的植物来源GP,尤其是在高温(如60℃-75℃)下能维持足够活性的GP仍然未知。对于来源于植物以外生物的GP,已经报道由极度嗜热细菌(水生栖热菌、Thermococcus litoralis、Aquifex aeolicus等)表达的、具有高度耐热性的GP。然而,因为以上这些GP来源于植物以外的生物,它们不能合成高分子量葡聚糖,因此有用性较差。
根据氨基酸序列的同源性(见非专利文献1)GP被分成两类。与马铃薯来源GP具有30%或更高一致性的GP归为A类GP,而与马铃薯来源GP具有低于30%一致性并与水生栖热菌的GP具有30%或更高一致性的GP归为B类GP。
与使用属于A类GP的马铃薯来源GP生产的葡聚糖相比,使用属于B类的Thermus来源的GP生产的葡聚糖具有较低的分子量。因此,存在不能使用Thermus来源的GP获得高分子量葡聚糖的问题。
为了解决这些问题,需要对工业应用有利且具有高度耐热性的植物来源GP。
已经尝试使一般酶具有更高耐热性的理论方法,如脯氨酸理论和基于酶立体结构信息的氨基酸替换,但并非都是成功的。因此,当前使用基于随机突变的方法,或使用随机突变和理论方法组合的方法。然而,在任何这些方法中,每种蛋白必须通过试错法来表征。
对于GP以外的其它酶,已经报道一旦确定参与提高酶耐热性的具体氨基酸位置,通过用其它氨基酸替换具体氨基酸残基,可以使酶具有耐热性(例如见非专利文献3-5)。
已经报道具有更高耐热性GP的实例,如大肠杆菌麦芽糊精磷酸化酶(见非专利文献2)。在此文献中,公开了热稳定大肠杆菌麦芽糊精磷酸化酶。麦芽糊精磷酸化酶是一种GP。在这种耐热化GP中,第133位天冬酰胺被丙氨酸替换。133位的这个天冬酰胺位于活性位点,并且是吡哆醛-5’-磷酸的结合位点,吡哆醛-5’-磷酸是所述酶反应必需的辅酶。在这种耐热化GP中,与天然GP比较,耐热性提高了约15℃,且最适反应温度从约45℃提高到约60℃,而所述GP在约67℃变性。然而,与Thermus来源的GP相似,这种大肠杆菌GP没有合成高分子量葡聚糖的能力。另外,在此文献中描述的耐热化GP在最适温度下的酶活性低于在最适温度下天然GP的酶活性。也就是说,由于突变,其合成葡聚糖的能力降低。因此,该文献教导133位替换不是优选的,至少从葡聚糖合成能力的观点看如此。
通常酶蛋白不稳定,并且对物理因素如pH、温度等以及蛋白酶敏感,因此容易降解。其中,也有酶在高度纯化时变得更不稳定,并因此容易降解。因此,酶必须在尽可能低的温度下制备,并且必须现用现制备。通过冷冻保存可以抑制酶降解。然而有些情况下蛋白质在融化过程中降解,因此当冷冻保存并随后融化酶时很难操作。一般来说,酶降解时立体结构改变,并且酶的性质如最适pH、pH稳定性、反应速率、底物亲和力等也相似的改变。偶尔所述酶活性被降低或灭活。这样,酶蛋白降解大大影响酶反应。因此,对于使用酶的工业,希望使用具有尽可能出色稳定性的酶。
已经知道天然马铃薯L型GP也容易降解,甚至当纯化GP冷藏保存时,也从纯化点逐渐降解。当可以抑制GP蛋白降解时,就可以制备大量GP并长期保存,从而增加生产效率,这对酶的保存和使用都是显著的优点。因此,也优选提供能长期保存而不降解的GP。

发明内容
本发明待解决问题
本发明意图解决前述问题,并且本发明的目的是提供比常规α-葡聚糖磷酸化酶具有更好耐热性的植物来源α-葡聚糖磷酸化酶。更具体的,本发明的目的是提供除了具有耐热性以外还具有出色保存稳定性的植物来源α-葡聚糖磷酸化酶。
解决问题的方式

本发明最佳实施方式
本发明将在下面解释。应该理解,在整篇本说明书,用于本说明书中的术语具有本领域正常使用的意思,除非另外具体说明。
(1.α-葡聚糖磷酸化酶)
本说明书中,除非另外具体说明,“α-葡聚糖磷酸化酶”和“GP”可互换使用,表示具有α-葡聚糖磷酸化酶活性的酶。α-葡聚糖磷酸化酶归类于EC2.4.1.1。α-葡聚糖磷酸化酶活性表示催化从无机磷酸和α-1,4-葡聚糖制备葡萄糖-1-磷酸和α-1,4-葡聚糖部分降解产物的反应或其逆反应的活性。α-葡聚糖磷酸化酶在有些情况下称为磷酸化酶、淀粉磷酸化酶、糖原磷酸化酶、麦芽糊精磷酸化酶等。α-葡聚糖磷酸化酶也可催化α-1,4-葡聚糖的合成反应,它是磷酸解的逆反应。任意特定反应的方向依赖于底物的量。在体内,由于无机磷酸的量大,葡聚糖磷酸化酶反应向磷酸解方向进行。当无机磷酸量少时,反应向合成α-1,4-葡聚糖方向进行。
好像所有已知α-葡聚糖磷酸化酶的活化都需要吡哆醛-5’-磷酸,并具有相似的催化机理。尽管不同来源酶的底物偏向性和调节形式不同,所有α-葡聚糖磷酸化酶都属于包括很多α-葡聚糖磷酸化酶的大组。这个大组包括来源于细菌、酵母和动物的糖原磷酸化酶、来源于植物的淀粉磷酸化酶和来源于细菌的麦芽糊精磷酸化酶。
已经报道,α-葡聚糖磷酸化酶的葡聚糖合成反应的最小引发分子是麦芽四糖。也已经报道葡聚糖降解反应的最小有效底物是麦芽戊糖。通常,认为这些是α-葡聚糖磷酸化酶的共同特征。然而,近些年,已经报道来自嗜热栖热菌的α-葡聚糖磷酸化酶和来自Thermococcus litoralis的α-葡聚糖磷酸化酶具有不同于其它α-葡聚糖磷酸化酶的底物特异性。对于这些α-葡聚糖磷酸化酶,葡聚糖合成的最小引发剂是麦芽三糖,而葡聚糖降解的最小底物是麦芽四糖。
α-葡聚糖磷酸化酶被认为广泛存在于能储存淀粉或糖原的多种植物、动物和细菌中。
产生α-葡聚糖磷酸化酶的植物的实例包括根和块茎作物如马铃薯(也称爱尔兰马铃薯)、甘薯、薯蓣、芋和木薯;蔬菜如甘蓝和菠菜;谷物如玉米、水稻、小麦、大麦、黑麦和粟;豆类如蚕豆、豌豆、大豆、赤豆和杂色菜豆(mottled kidney bean);实验植物如拟南芥;柑桔杂交栽培种,藻类等。
产生α-葡聚糖磷酸化酶的植物不限于以上实例。
用于本发明方法的第一种α-葡聚糖磷酸化酶优选是天然α-葡聚糖磷酸化酶并来源于植物。通常,来源于植物的天然α-葡聚糖磷酸化酶有能力合成高分子量的直链淀粉。然而,这些α-葡聚糖磷酸化酶的耐热性较低。因此它们不能在高温下(如约60℃或更高)催化反应。因此,当在植物(如马铃薯)来源GP的最适反应温度,即约30℃到约40℃进行反应时,出现多种微生物污染或所述葡聚糖老化的问题,并且葡聚糖或G-1-P不能被有效产生。
根据对糖原的亲和力,植物α-葡聚糖磷酸化酶分成L型和H型。L型α-葡聚糖磷酸化酶表示对糖原具有低亲和力的α-葡聚糖磷酸化酶。通常,L型α-葡聚糖磷酸化酶优先选择麦芽糊精、直链淀粉和支链淀粉而不是糖原作为底物(Hiroyuki Mori,et al.,“A Chimeric α-glucan phosphorylase of Plant Type L and H Isozyme”,The Journal ofBiological Chemistry,1993,vol.268,No.8,pp.5574-5581)。H型α-葡聚糖磷酸化酶表示对糖原具有高亲和力的α-葡聚糖磷酸化酶。通常,H型α-葡聚糖磷酸化酶对多种葡聚糖包括糖原具有极高亲和力。
例如,根据Toshio Fukui,et al.,Biochemistry of Vitamin B6,1987,pp.267-276,马铃薯叶来源的L型α-葡聚糖磷酸化酶对糖原的Km(米氏常数)是1.4×10-3(M),而马铃薯叶来源的H型α-葡聚糖磷酸化酶产生糖原的Km是4×10-6(M)。此外,马铃薯块茎来源α-葡聚糖磷酸化酶的主要组分产生糖原的Km是2.4×10-3(M),被分类为L型。次要组分α-葡聚糖磷酸化酶产生糖原的Km是1×10-6(M),被分类为H型。
本领域已知,米氏常数是由酶促反应初始速率对底物浓度依赖性确定的动力学参数之一。米氏常数是当初始速率是最大速率Vmax的1/2时的底物浓度。米氏常数具有浓度单位。米氏常数随酶的具体测定条件而改变。该常数是表示酶对底物亲和力的量度。当米氏常数变小时,对底物的亲和力变大。
例如,L型α-葡聚糖磷酸化酶和H型α-葡聚糖磷酸化酶在特征方面具有以下不同。
(表2)
L型GP | H型GP | |
抗体与马铃薯块茎来源GP的主要组分的交叉反应 | 有 | 无 |
抗体与马铃薯块茎来源GP的次要组分的交叉反应 | 无 | 有 |
蛋白水解敏感性 | 高 | 低 |
定位 | 质体(造粉体或叶绿体) | 胞浆 |
在一个具体实施方案中,进一步优选的是,用于本发明方法的α-葡聚糖磷酸化酶是L型α-葡聚糖磷酸化酶。马铃薯L型α-葡聚糖磷酸化酶比马铃薯H型α-葡聚糖磷酸化酶更长,并包含H型中没有的78个残基的氨基酸序列,该序列插入所述多肽链的中心区。因此,举例来说,马铃薯叶来源L型α-葡聚糖磷酸化酶亚基的分子量约为104,000Da,而马铃薯叶来源H型α-葡聚糖磷酸化酶亚基的分子量约是94,000Da。马铃薯块茎来源α-葡聚糖磷酸化酶主要组分亚基的分子量约是104,000Da,而马铃薯块茎来源α-葡聚糖磷酸化酶次要组分亚基的分子量约是94,000Da。特定α-葡聚糖磷酸化酶是L型还是H型可通过是否存在与78残基的该氨基酸序列的同源区域来确定,而不需实际测定亲和力。
一般来说,L型和H型的确定是通过综合考虑多种特性如酶活性、分子量、底物特异性、酶定位、一级序列同源性和插入序列的存在性。因此,一般来说,有些情况下L型和H型的边界是不清楚的,但为了方便,在本发明中,α-葡聚糖磷酸化酶是L型还是H型可通过α-葡聚糖磷酸化酶中是否存在转运肽来确定。转运肽序列的特征在本领域已知。编码转运肽的序列是L型,而不编码转运肽的序列是H型。

在另一个实施方案中,用于本发明方法的第一种(天然)α-葡聚糖磷酸化酶优选是H型α-葡聚糖磷酸化酶。产生H型α-葡聚糖磷酸化酶的植物的实例包括马铃薯、小麦、柑桔杂交栽培种、水稻、蚕豆、拟南芥和甘薯。

用于本发明方法的第一种(天然)α-葡聚糖磷酸化酶优选来源于植物,并优选来源于马铃薯、甘薯、蚕豆、拟南芥、菠菜、玉米、水稻、小麦或柑桔杂交栽培种,更优选来源于马铃薯、甘薯、蚕豆、拟南芥、菠菜、玉米或水稻,最优选来源于马铃薯。用于本发明方法的所述第一种(天然)α-葡聚糖磷酸化酶优选是L型α-葡聚糖磷酸化酶。用于本发明方法的所述第一种(天然)α-葡聚糖磷酸化酶优选是来源于马铃薯的L、L2或H型α-葡聚糖磷酸化酶,来源于甘薯的L或H型α-葡聚糖磷酸化酶,来源于蚕豆的L或H型α-葡聚糖磷酸化酶,来源于拟南芥的L或H型α-葡聚糖磷酸化酶,来源于菠菜的L型α-葡聚糖磷酸化酶,来源于玉米的L型α-葡聚糖磷酸化酶,来源于水稻的L或H型α-葡聚糖磷酸化酶,来源于小麦的H型α-葡聚糖磷酸化酶,或来源于柑桔杂交栽培种的H型α-葡聚糖磷酸化酶;更优选是来源于马铃薯的L或L2型α-葡聚糖磷酸化酶,来源于甘薯的L型α-葡聚糖磷酸化酶,来源于蚕豆的L型α-葡聚糖磷酸化酶,来源于拟南芥的L型α-葡聚糖磷酸化酶,来源于菠菜的L型α-葡聚糖磷酸化酶,来源于玉米的L型α-葡聚糖磷酸化酶,或来源于水稻的L型α-葡聚糖磷酸化酶;最优选是来源于马铃薯的L型α-葡聚糖磷酸化酶。
在本说明书中,“来源于”一种生物的酶不仅表示所述酶直接从所述生物分离,而且表示通过使用任意形式的所述生物而获得的酶。例如,当编码从一种生物获得的酶的基因引入大肠杆菌,并且随后从大肠杆菌分离所表达酶时,所述酶被称为是“来源于”所述生物。
例如,可用以下程序制备编码来源于马铃薯的L型GP的基因。
首先,如Takaha et al.(Journal of Biological Chemistry,Vol.268,pp.1391-1396,1993)所述,使用公知的方法从马铃薯块茎制备mRNA,并用商品试剂盒制备cDNA文库等。
然后,基于已知的GP基因序列(数据库GenBank登记号D00520)制备PCR引物,并用前述cDNA文库作模板进行PCR。例如,当:
PCR引物1:5′AAATCGATAGGAGGAAAACAT ATG ACC TTG AGT GAG AAA AT 3’(SEQ ID NO:38)
和
PCR引物2:5′GAAGGTACCTTTTCATTCACTTCCCCCTC3′(SEQ ID NO:39)用作PCR引物时,在以下条件下可扩增一种基因。
进行30个循环PCR反应,一个循环是94℃30秒、50℃1分钟和72℃3分钟。
所述PCR引物1的下划线部分对应L型GP成熟蛋白N端区的结构基因序列,而所述PCR引物2的下划线部分对应L型GP结构基因终止密码子即下游的碱基序列。
作为替代方案,也可基于所述已知基因序列信息而直接经化学合成制备GP基因,而不需制备cDNA文库。例如,合成基因的方法描述于Te’o,et al.,(FEMSMicrological Letters,vol.190,pp.13-19,2000)。
可通过本领域技术人员熟知的方法将所得GP基因插入合适的载体。例如可以使用pMW118(Nippon Gene Co.,Ltd.制造)、pUC18(TAKARA BIO制造)、pKK233-2(Amersham-Pharmacia-Biotech制造)、pET3d(STRATAGENE制造)等作为用于大肠杆菌的载体,使用pUB110(可以从American Type Culture Collection购买)和pHY300PLK(TAKARABIO制造)等作为用于枯草杆菌的载体。
例如,当用PCR引物1和2扩增基因时,可以通过将所扩增基因插入预先用SmaI切割的质粒pMW118选择具有图2所示序列的质粒。这用于转化,例如,大肠杆菌TG-1,然后选择氨苄青霉素抗性株,并培养携带所得重组质粒的菌株,通过提取质粒可以获得GP基因。
(2.提高α-葡聚糖磷酸化酶的耐热性)
根据本发明的方法包括修饰含编码第一种α-葡聚糖磷酸化酶的碱基序列的第一种核酸分子,以获得含修饰碱基序列的第二种核酸分子;制备含所述第二种核酸分子的表达载体;将所述表达载体导入细胞中,以表达耐热化α-葡聚糖磷酸化酶,和回收所表达的耐热化α-葡聚糖磷酸化酶.
(2.1分离含编码第一种(天然)α-葡聚糖磷酸化酶的碱基序列的核酸分子)
根据本发明含编码耐热化α-葡聚糖磷酸化酶的碱基序列的核酸分子也在本发明范围内。基于本说明书的公开内容,这样的核酸分子可用本领域已知方法获得。
如上所述,含编码天然α-葡聚糖磷酸化酶的碱基序列的核酸分子可以直接从产生天然存在α-葡聚糖磷酸化酶的植物中分离。
例如,首先从马铃薯、拟南芥、菠菜等中分离天然α-葡聚糖磷酸化酶。为举例说明马铃薯来源的α-葡聚糖磷酸化酶的程序,首先,1.4kg商品马铃薯块茎去皮。所述已经去皮的块茎在榨汁机中捣碎得到糊状流体。然后用仪器过滤此糊状流体得到滤液。向滤液中加入Tris缓冲液(pH7.0)到终浓度100mM,得到酶溶液。此酶溶液进而在55℃水浴加热10分钟,之后液体温度达到50℃。加热后此酶溶液用离心机(BECKMAN制造的AVANTI J-25I)在8,500rpm离心20分钟,以除去不溶性蛋白,并得到上清液。
向上清液中加入硫酸铵至终浓度100g/L,4℃静置2小时以沉淀蛋白。然后用离心机(BECKMAN制造的AVANTI J-25I)在8,500rpm离心溶液20分钟,以除去不溶性蛋白。再加入硫酸铵到所得上清液中至终浓度250g/L,并在4℃静置2小时以沉淀蛋白。然后用离心机(BECKMAN制造的AVANTI J-25I)在8,500rpm离心溶液20分钟,以回收不溶性蛋白。
回收的不溶性蛋白悬于150ml 25mM Tris缓冲液(pH7.0)。重悬的酶溶液对相同缓冲液透析过夜。透析后样品吸附到已经预先平衡的阴离子交换树脂Q-Sepharose(Pharmacia制造)上,然后用含200mM氯化钠的缓冲液洗涤。随后用含400mM氯化钠的缓冲液洗脱蛋白,并回收洗脱液,得到含部分纯化的马铃薯块茎来源葡聚糖磷酸化酶的溶液。
取决于所购买马铃薯,此阶段获得的含α-葡聚糖磷酸化酶溶液可用于胰酶处理,但在有些情况下需要进一步纯化。在这些情况下,如果必要,通过组合来自使用例如Sephacryl S-200HR(Pharmacia制造)的凝胶过滤层析的组分和来自使用例如Phenyl-TOYOPEARL650M(Tosoh Corporation制造)的疏水层析的组分,可以获得所述含纯化马铃薯α-葡聚糖磷酸化酶的溶液。可相似的从其它植物物种中纯化α-葡聚糖磷酸化酶。
用胰酶处理由此获得的纯化α-葡聚糖磷酸化酶,所得胰酶处理片段通过HPLC分离,用肽测序仪确定每个分离肽片段的N端氨基酸序列。然后用基于鉴定氨基酸序列而制备的合成寡核苷酸探针,筛选合适的基因组文库或cDNA文库,从而获得含编码天然α-葡聚糖磷酸化酶的碱基序列的核酸分子(也称基因)。制备寡核苷酸探针和cDNA文库以及通过核酸杂交筛选它们的基本策略对本领域技术人员公知。例如,见Sambrook,et al.,Molecular Cloning:A laboratory Manual(1989);DNA Cloning,vol.Iand II(edited by D.N.Glover,1985);Oligonucleotide Synthesis(edited by M.J.Gait,1984);Nucleic Acid Hybridization(edited by B.D.Hames & S.J.Higgins,1984)。
作为替代方案,基于与编码α-葡聚糖磷酸化酶的碱基序列已知的某些α-葡聚糖磷酸化酶碱基序列的同源性,例如,用含至少部分该碱基序列的核酸探针通过杂交而筛选cDNA文库或基因组文库,从而获得含另一种α-葡聚糖磷酸化酶碱基序列的核酸分子。这些方法在本领域已知。
作为替代方案,制备简并引物,它们对应于多种α-葡聚糖磷酸化酶氨基酸序列中的保守区域,并使用例如目标物种的cDNA文库或基因组文库作模板进行PCR,获得来源于所述物种的α-葡聚糖磷酸化酶的碱基序列。这些方法在本领域已知。
筛选基因组文库或cDNA文库时,可以使用本领域技术人员熟知的方法亚克隆所得核酸分子。例如通过混合含目标基因的λ噬菌体、合适的大肠杆菌和合适的辅助噬菌体,可以容易的获得含目标基因的质粒。而后,可以通过用含质粒的溶液转化合适的大肠杆菌来亚克隆目标基因。可以通过培养所得转化体,例如经碱SDS方法获得质粒DNA,并确定目标基因的碱基序列。确定碱基序列的方法对本领域技术人员公知。进而,通过使用基于DNA片段碱基序列合成的PCR引物,并使用马铃薯的基因组DNA或cDNA作模板的聚合酶链式反应(PCR),可以直接扩增α-葡聚糖磷酸化酶基因。
在本说明书中,所述“核酸分子”可只由天然核苷酸组成,可以含有非天然核苷酸,或可以只由非天然核苷酸组成。非天然核苷酸的实例包括衍生核苷酸(也称核苷酸类似物)。所述“衍生核苷酸”和所述“核苷酸类似物”表示那些不同于天然存在核苷酸但与起源核苷酸具有相似功能的核苷酸。这些衍生核苷酸和核苷酸类似物在本领域公知。这些衍生核苷酸和核苷酸类似物的实例包括但不限于硫代磷酸酯、氨基磷酸酯、甲基膦酸酯、手性甲基膦酸酯、2-O-甲基核糖核苷酸和肽核酸(PNA)。
(2.2修饰含编码第一种α-葡聚糖磷酸化酶的碱基序列的所述第一种核酸分子)
修饰含编码第一种α-葡聚糖磷酸化酶的碱基序列的第一种核酸分子,获得含修饰碱基序列的第二种核酸分子。第一种核酸分子可以是如上(2.1)获得的含编码天然α-葡聚糖磷酸化酶的碱基序列的核酸分子。所述第一种核酸分子也可以是含编码α-葡聚糖磷酸化酶的碱基序列的核酸分子,其中所述α-葡聚糖磷酸化酶具有与天然α-葡聚糖磷酸化酶基本相同的酶活性,并且其中1个或几个或更多氨基酸被替换、缺失或添加到编码天然α-葡聚糖磷酸化酶的碱基序列中。“具有基本相同酶活性”表示,在与修饰前α-葡聚糖磷酸化酶相同条件下测定修饰后α-葡聚糖磷酸化酶时,酶活性范围是修饰前α-葡聚糖磷酸化酶酶活性在±20%、优选±10%、更优选±5%的范围内。
可通过定点突变、用诱变剂突变(用致突变剂如亚硝酸盐、紫外线处理受研究基因)或易错PCR进行修饰。从容易获得目标突变的角度来看优选使用定点突变,因为当使用定点突变时可在目标位点引入目标修饰。作为替代方案,可直接合成含目标序列的核酸分子。这些化学合成方法在本领域公知。
本发明人发现,通过在来源于植物的α-葡聚糖磷酸化酶氨基酸序列中特定位置用另一个氨基酸残基替换氨基酸残基,可提高所得α-葡聚糖磷酸化酶的耐热性。这种特定位置可通过比对以下任意基序序列或SEQ ID NO:2的氨基酸序列、并比较受研究氨基酸序列而确定:
基序序列1L:H-A-E-F-T-P-V-F-S(SEQ ID NO:44)
或基序序列1H:H-A-Q-Y-S-P-H-F-S(SEQ ID NO:45),
基序序列2:A-L-G-N-G-G-L-G(SEQ ID NO:46),和
基序序列3L:R-I-V-K-F-I-T-D-V(SEQ ID NO:47)
或基序序列3H:R-I-V-K-L-V-N-D-V(SEQ ID NO:48)。
基序序列1L、2和3L存在于马铃薯来源的L型α-葡聚糖磷酸化酶氨基酸序列(SEQ ID NO:2)中。这些基序序列存在于马铃薯L型α-葡聚糖磷酸化酶的以下位置:基序序列1L:SEQ ID NO:2中氨基酸序列的第36位到第44位;基序序列2:SEQ IDNO:2中氨基酸序列的第132位到第139位;基序序列3L:SEQ ID NO:2中氨基酸序列的第700位到第708位。基序序列1H、2和3H存在于水稻来源的H型α-葡聚糖磷酸化酶氨基酸序列中。这些基序序列存在于水稻H型α-葡聚糖磷酸化酶的以下位置:基序序列1H:SEQ ID NO:24中氨基酸序列的第36位到第44位;基序序列2:SEQ IDNO:24中氨基酸序列的第132位到第139位;基序序列3H:SEQ ID NO:2中氨基酸序列的第625位到第633位。一般的,天然α-葡聚糖磷酸化酶具有这些基序序列或与它们高度同源的序列。本领域技术人员可以容易的确定这些基序序列在其它植物来源的α-葡聚糖磷酸化酶中的位置。
在根据本发明的方法中,修饰含编码第一种α-葡聚糖磷酸化酶的碱基序列的核酸分子,以得到由修饰核酸分子编码的耐热化α-葡聚糖磷酸化酶,所述耐热化α-葡聚糖磷酸化酶在选自下组的至少一个位置具有与所述天然α-葡聚糖磷酸化酶不同的氨基酸残基:对应SEQ ID NO:2的氨基酸序列中第39位苯丙氨酸(F39)的位置;对应第135位天冬酰胺(N135)的位置;和对应第706位苏氨酸(T706)的位置。优选的,修饰含编码所述第一种α-葡聚糖磷酸化酶的碱基序列的核酸分子,以得到由修饰核酸分子编码的耐热化α-葡聚糖磷酸化酶的氨基酸序列,与所述天然α-葡聚糖磷酸化酶相比,所述耐热化α-葡聚糖磷酸化酶的氨基酸序列在以下位置不同:对应SEQ ID NO:2氨基酸序列中对应第39位苯丙氨酸(F39)的位置或对应第706位苏氨酸(T706)的位置。
如本说明书所用,“对应SEQ ID NO:2氨基酸序列中第39位苯丙氨酸(F39)的位置”表示,当受研究氨基酸序列和SEQ ID NO:2氨基酸序列进行比对以使两序列之间同源性最大时,如果必要可以在一个序列中插入间隙,与SEQ ID NO:2氨基酸序列中第39位苯丙氨酸(F39)匹配的位置。当在SEQ ID NO:2中插入间隙时,当计算氨基酸残基数目时不计间隙。更优选,以上短语表示当SEQ ID NO:2氨基酸序列与受研究氨基酸序列在间隙罚分(GAP Penalty)(Peptide)条件下进行比对时,与SEQ ID NO:2中第39位苯丙氨酸(F39)匹配的位置,其中所述比对条件是:在GENETYX-WINVer.4.0的多重比对中,Insert=-10,Extend=-3,gap Extend on top position:setted(checked),Match Mode:Local Match using a score table of default。关于氨基酸的默认记分表示于下表3。

GENETYX-WIN Ver.4.0的多重比对基于以下算法。在这个比对程序中,所有可能的序列配对被比对,两序列比对循环进行(成对比对),并且其中具有高保守比例(成对比对中的评分)组合的序列被确定为共有序列,从共有序列产生假想序列(共有部分保持不变,同时对于非共有部分选择所述序列的任意一个)。用相同程序产生除了组成假想序列的序列以外的所有序列与假想序列之间的循环比较,直到产生最终的假想序列。此后,通过将有关用于产生所述假想序列的GAP插入和移位信息应用到所述起始序列,以组成整体,从而完成多重比对。用于这种成对比对的计算公式如下。
当序列a和b每个分别具有序列长度m或n时,各自序列表达为:
a=a1 a2 a3...am
b=b1 b2 b3...bm,
间隙罚分(GAP penalty)g用以下方程表示:
-g=s(ai,φ)=a(φ,bj).
获得比对记分的方程如下:
G(0,0)=0
G(i,0)=i(-g)
G(0,j)=j(-g)
-gk=-[α+β(k-1)]
E(i,j)={G(i-1,j)-α,E(i-1,j)-β}
F(i,j)=max{G(i,j-1)-α,F(i,j-1)-β}
G(i,j)=max{E(i,j),G(i-1,j-1)+s(ai,bj),F(i,j)}
α是间隙插入罚分(GAP insertion penalty),β是间隙延长罚分(GAP extensionpenalty)。E、F和G是记分矩阵(score matrix),基于此,产生pass matrix。

提高耐热性的氨基酸残基位置不仅可以通过与SEQ ID NO:2的916个氨基酸残基序列比对来确定,而且可以通过与选自前述基序序列1L或1H、2、和3L或3H的一个或多个序列比对来确定。就目前已知的植物来源的α-葡聚糖磷酸化酶进行比对,不论是使用SEQ ID NO:2的情况下,还是使用基序序列1L或1H、2、和3L或3H的情况下,所确定的位置都是相同的。
基序序列1L在L型α-葡聚糖磷酸化酶中很保守,而基序序列1H在H型α-葡聚糖磷酸化酶中很保守。可以说对应SEQ ID NO:2氨基酸序列中第39位苯丙氨酸(F39)的位置是对应基序序列1L或1H中第4位的位置。
基序序列2在L型和H型α-葡聚糖磷酸化酶中通常保守。可以说对应SEQ IDNO:2氨基酸序列中第135位天冬酰胺(N135)的位置是对应基序序列2中第4位的位置。
基序序列3L在L型α-葡聚糖磷酸化酶中很保守,而基序序列3H在H型α-葡聚糖磷酸化酶中很保守。可以说对应SEQ ID NO:2氨基酸序列中第706位苏氨酸(T706)的位置是对应基序序列3L或3H中第7位的位置。
这样,也可用所述基序序列指定提高耐热性的氨基酸残基位置。提高耐热性的氨基酸残基位置可以是选自下组的至少一个位置:对应基序序列1L:H-A-E-F-T-P-V-F-S中第4位的位置或对应基序序列1H:H-A-Q-Y-S-P-H-F-S中第4位的位置;对应基序序列2:A-L-G-N-G-G-L-G中第4位的位置;和对应基序序列3L:R-I-V-K-F-I-T-D-V中第7位的位置或对应基序序列3H:R-I-V-K-L-V-N-D-V中第7位的位置。
因此,在根据本发明的方法中,可以说含编码第一种α-葡聚糖磷酸化酶的碱基序列的核酸分子被这样修饰,使得由修饰核酸编码的耐热化α-葡聚糖磷酸化酶在选自下组的至少一个位置具有不同于所述天然α-葡聚糖磷酸化酶氨基酸残基的氨基酸残基:对应基序序列1L:H-A-E-F-T-P-V-F-S中第4位的位置或对应基序序列1H:H-A-Q-Y-S-P-H-F-S中第4位的位置;对应基序序列2:A-L-G-N-G-G-L-G中第4位的位置;和对应基序序列3L:R-I-V-K-F-I-T-D-V中第7位的位置或对应基序序列3H:R-I-V-K-L-V-N-D-V中第7位的位置。
本说明书中,所述“基序序列”表示在多种蛋白的氨基酸序列之间见到的、共有或高度保守的部分序列。一般的,所述基序序列在很多情况下具有特定功能,但在本说明书中,甚至当未确定具体功能时,只要所述序列在多种氨基酸序列之间保守,就称为基序序列。
“基序序列1L中第4位”氨基酸残基表示当将所述基序序列1L的N端(左端)的氨基酸残基当作第1位时依次计数的第4位氨基酸残基。“基序序列1H中第4位”、“基序序列2中第4位”、“基序序列3L中第7位”、“基序序列3H中第7位”等都与前相似。
这些基序序列在植物α-葡聚糖磷酸化酶中通常非常保守。所述基序序列1L或1H和3L或3H在α-葡聚糖植物磷酸化酶中非常保守,但在来源于动物、微生物等的α-葡聚糖磷酸化酶中不保守。基序序列2在几乎所有生物如植物、动物和微生物的α-葡聚糖磷酸化酶中非常保守。所述基序序列2含有被认为参与结合底物和结合吡哆醛-5’-磷酸的氨基酸残基、并是活性必需区域的一部分,其中吡哆醛-5’-磷酸是辅酶。基序序列1L和1H的位置和基序序列2的位置在图1B中示出。基序序列3L和3H的位置在图1G中示出。
如此处所用,“对应基序序列1L:H-A-E-F-T-P-V-F-S中第4位的位置或对应基序序列1H:H-A-Q-Y-S-P-H-F-S中第4位的位置”表示:当在不插入间隙以使序列间同源性最大条件下,将受研究氨基酸序列和所述基序序列1L或所述基序序列1H进行比对时,与所述基序序列1L或所述基序序列1H中第4位氨基酸残基匹配的位置。更优选的,它表示当在无间隙条件下进行GENETYX-WIN Ver.4.0(GeneticsCo.,Ltd.)的最大匹配时,与所述基序序列1L或所述基序序列1H中第4位氨基酸残基匹配的位置。
以相似方式来解释对应基序序列2中第4位的位置,和对应基序序列3L中第7位的位置或对应基序序列3H中第7位的位置。
GENETYX-WIN Ver.4.0的最大匹配如下:考虑替换和缺失,待分析的序列数据和待比较的序列数据进行比对,使得这些序列之间的氨基酸配对匹配最大,并因此分别对匹配(Matches)、错配(Mismatches)和间隙(Gaps)进行评分,计算总和,并输出最低总和的比对结果(参考文献:Takashi,K.,and Gotoh,O.1984.SequenceRelationships among Various 4.5 S RNA Species J.Biochem.92:1173-1177)。优选在Matches=-1、Mismatches=1、Gaps=None、*N+=2的条件下进行比对。

在GENETYX-WIN Ver.4.0的最大匹配中,在前述条件下,SEQ ID NO:4、SEQ IDNO:6、SEQ ID NO:8、SEQ ID NO:10、SEQ ID NO:12、SEQ ID NO:14、SEQ ID NO:16、SEQ ID NO:18、SEQ ID NO:20、SEQ ID NO:22、SEQ ID NO:24、SEQ ID NO:26、SEQID NO:28和SEQ ID NO:30与每一种基序序列(基序序列1L、1H、2、3L或3H)进行比对。结果,苯丙氨酸或酪氨酸与对应基序序列1L中第4位的位置或对应基序序列1H中第4位的位置匹配,天冬酰胺与对应基序序列2中第4位的位置匹配,而苏氨酸、天冬酰胺或天冬氨酸与对应基序序列3L中第7位的位置或对应基序序列3H中第7位的位置匹配。所述基序序列1L、2和3L是SEQ IDNO:2的部分序列,而所述基序序列1H、2和3H是SEQ ID NO:24的部分序列。
对于SEQ ID NO:4、SEQ ID NO:6、SEQ ID NO:8、SEQ ID NO:10、SEQ ID NO:12、SEQ ID NO:14、SEQ ID NO:16、SEQ ID NO:18、SEQ ID NO:20、SEQ ID NO:22、SEQID NO:24、SEQ ID NO:26、SEQ ID NO:28和SEQ ID NO:30中的每一种,将使用SEQID NO:2全长的比对结果和使用基序序列1L、1H、2、3L和3H的比对结果进行比较。结果,在SEQ ID NO:4、SEQ ID NO:6、SEQ ID NO:8、SEQ ID NO:10、SEQ ID NO:12、SEQ ID NO:14、SEQ ID NO:16、SEQ ID NO:18、SEQ ID NO:20、SEQ ID NO:22、SEQID NO:24、SEQ ID NO:26、SEQ ID NO:28和SEQ ID NO:30中的每一种中,对应SEQID NO:2中第39位的位置和对应所述基序序列1L或1H中第4位的位置相同;对应SEQ ID NO:2中第135位的位置和对应所述基序序列2中第4位的位置相同;对应SEQID NO:2中第706位的位置和对应所述基序序列3L或3H中第7位的位置相同。这样就证实:甚至当用基序序列进行比对时,所指定位置与使用SEQ ID NO:2氨基酸序列时指定的位置相同。
含修饰碱基序列的核酸分子位于本发明范围内,所述核酸分子通过修饰含编码下面所示氨基酸序列的碱基序列的核酸分子而获得:序列表中的SEQ ID NO:2的第1位到第916位,SEQ ID NO:4的第1位到第912位,SEQ ID NO:6的第1位到第893位,SEQ ID NO:8的第1位到第939位,SEQ ID NO:10的第1位到第962位,SEQ IDNO:12的第1位到第971位,SEQ ID NO:14的第1位到第983位,SEQ ID NO:16的第1位到第928位,SEQ ID NO:18的第1位到第951位,SEQ ID NO:20的第1位到第832位,SEQ ID NO:22的第1位到第840位,SEQ ID NO:24的第1位到第841位,SEQ ID NO:26的第1位到第842位,SEQ ID NO:28的第1位到第841位,和SEQ IDNO:30的第1位到第838位。
含修饰碱基序列的核酸分子位于本发明范围内,所述核酸分子通过修饰含下面给出的碱基序列的核酸分子而获得:序列表中的SEQ ID NO:1、SEQ ID NO:3、SEQ IDNO:5、SEQ ID NO:7、SEQ ID NO:9、SEQ ID NO:11、SEQ ID NO:13、SEQ ID NO:15、SEQ ID NO:17、SEQ ID NO:19、SEQ ID NO:21、SEQ ID NO:23、SEQ ID NO:25、SEQID NO:27或SEQ ID NO:29。
含修饰碱基序列的核酸分子位于本发明范围内,所述核酸分子通过修饰含编码一定氨基酸序列的碱基序列的核酸分子而获得,所述氨基酸序列与选自下组的氨基酸序列具有至少50%一致性:序列表中的SEQ ID NO:2的第1位到第916位,SEQ IDNO:4的第1位到第912位,SEQ ID NO:6的第1位到第893位,SEQ ID NO:8的第1位到第939位,SEQ ID NO:10的第1位到第962位,SEQ ID NO:12的第1位到第971位,SEQ ID NO:14的第1位到第983位,SEQ ID NO:16的第1位到第928位,SEQ IDNO:18的第1位到第951位,SEQ ID NO:20的第1位到第832位,SEQ ID NO:22的第1位到第840位,SEQ ID NO:24的第1位到第841位,SEQ ID NO:26的第1位到第842位,SEQ ID NO:28的第1位到第841位,和SEQ ID NO:30的第1位到第838位。
在本发明中,序列如氨基酸序列和碱基序列的“一致性”表示两序列之间出现相同氨基酸(当比较碱基序列时为碱基)的程度。一致性的确定通常是通过比较两种氨基酸序列或两种碱基序列,并比较以最佳方式匹配的这两种序列,其中可以含有插入或缺失。一致性百分率的计算是通过确定这两种序列之间相同氨基酸(当比较碱基序列时为碱基)位置的数目、将相同位置的数目除以比较位置的总数、并将所得结果乘以100而得到这两种序列之间的一致性百分率。
作为实例,用于获得本发明耐热化α-葡聚糖磷酸化酶的天然α-葡聚糖磷酸化酶的氨基酸序列可以与选自下组的氨基酸序列(即对照氨基酸序列)相同,也即100%一致:SEQ ID NO:2的第1位到第916位,SEQ ID NO:4的第1位到第912位,SEQ IDNO:6的第1位到第893位,SEQ ID NO:8的第1位到第939位,SEQ ID NO:10的第1位到第962位,SEQ ID NO:12的第1位到第971位,SEQ ID NO:14的第1位到第983位,SEQ ID NO:16的第1位到第928位,SEQ ID NO:18的第1位到第951位,SEQ ID NO:20的第1位到第832位,SEQ ID NO:22的第1位到第840位,SEQ IDNO:24的第1位到第841位,SEQ ID NO:26的第1位到第842位,SEQ ID NO:28的第1位到第841位,和SEQ ID NO:30的第1位到第838位,或与对照氨基酸序列相比该氨基酸序列含有一个或多个改变氨基酸残基。这些改变可以选自至少一个氨基酸的缺失、包括保守和非保守替换的替换、或插入。这种改变可以发生在对照氨基酸序列的氨基端或羧基端,或发生在这些末端以外的其它任意位置。氨基酸残基改变可以与一个残基分散分布,或几个残基可以连续。
在本说明书中,使用GENETYX-WIN Ver.4.0(Genetics Co.,Ltd.)的最大匹配计算序列的一致性百分率。该程序比对待分析序列数据和待比较序列数据,使得序列间匹配的氨基酸对最多,同时还考虑替换和缺失,并因此得到匹配(Matches)、错配(Mismatches)和间隙(Gaps)的评分,计算总和,并输出最小总和的比对结果,从而计算一致性百分率(参考文献:Takashi,K.,and Gotoh,O.1984.SequenceRelationships among Various 4.5 S RNA Species J.Biochem.92:1173-1177)。
使用GENETYX-WIN Ver.4.0的最大匹配,计算马铃薯L型(SEQ ID NO:2)、甘薯L型(SEQ ID NO:4)、马铃薯另一种L型(SEQ ID NO:6)、蚕豆L型(SEQ ID NO:8)、拟南芥L型(SEQ ID NO:10)、菠菜L型(SEQ ID NO:12)、玉米L型(SEQ ID NO:14)、水稻L型(SEQ IDNO:16)、水稻第二种L型(SEQ IDNO:18)、小麦H型(SEQ IDNO:20)、柑桔杂交栽培种H型(SEQ ID NO:22)、水稻H型(SEQ ID NO:24)、蚕豆H型(SEQ ID NO:26)、拟南芥H型(SEQ ID NO:28)和马铃薯H型(SEQ ID NO:30)与马铃薯L型(SEQ ID NO:2)之间的一致性百分率,结果示于表4。在Matches=-1、Mismatches=1、Gaps=1、*N+=2的条件下分析最大匹配。

含修饰碱基序列的核酸分子位于本发明范围内,所述核酸分子通过修饰在严谨条件下与由选自下组的碱基序列组成的核酸分子而获得:序列表中的SEQ ID NO:1、SEQ ID NO:3、SEQ ID NO:5、SEQ ID NO:7、SEQ ID NO:9、SEQ ID NO:11、SEQ IDNO:13、SEQ ID NO:15、SEQ ID NO:17、SEQ ID NO:19、SEQ ID NO:21、SEQ ID NO:23、SEQ ID NO:25、SEQ ID NO:27和SEQ ID NO:29。本领域技术人员可容易的选择期望的α-葡聚糖磷酸化酶基因。
如此处所用,术语“严谨条件”表示这样的条件,在此条件下序列与特异性序列杂交但不与非特异性序列杂交。适当严谨条件的选择对本领域技术人员公知,并描述于例如Molecular Cloning(Sambrook,et al.,同上)。具体的,所述条件意味着使用所述条件可以鉴定多核苷酸,在此条件下,在一种溶液中用固定有来源于菌落或噬斑的DNA的滤膜在65℃进行杂交,所述溶液含50%甲酰胺、5×SSC(750mM NaCl,75mM柠檬酸三钠)、50mM磷酸钠(pH7.6)、5×Denhart’s溶液(0.2% BSA、0.2% Ficoll 400和0.2%聚乙烯吡咯烷酮)、10%硫酸葡聚糖和20μg/ml变性剪切鲑精DNA,并用0.1-2倍浓度的SSC(盐水-柠檬酸钠)溶液(一倍浓度的SSC溶液组成是150mM NaCl、15mM柠檬酸钠)在65℃条件下洗涤滤膜。
用于本发明方法的修饰核酸分子可以是相对于含编码第一种α-葡聚糖磷酸化酶碱基序列的核酸分子而被保守性修饰的核酸分子。所述“相对于含编码第一种α-葡聚糖磷酸化酶碱基序列的核酸分子而被保守性修饰的核酸分子”表示含编码一定氨基酸序列的碱基序列的核酸分子,所述氨基酸序列与由编码第一种α-葡聚糖磷酸化酶的碱基序列编码的氨基酸序列相同或基本相同。所述“与由编码第一种α-葡聚糖磷酸化酶的碱基序列编码的氨基酸序列相同或基本相同的氨基酸序列”表示与第一种α-葡聚糖磷酸化酶具有基本相同酶活性的氨基酸序列。由于遗传密码的简并性,很多功能等价的碱基序列编码指定的氨基酸序列。例如密码子GCA、GCC、GCG和GCT都编码丙氨酸。因此,在所有由GCA密码子指定的丙氨酸位置上,密码子可以换成GCC、GCG或GCT,不改变所编码的丙氨酸。相似的,对于由多个密码子编码的氨基酸,在所有由一个密码子指定的氨基酸位置,所述密码子可以换成编码所述氨基酸的任意另一个密码子,而不改变所编码具体氨基酸。碱基序列的这种变化是“沉默突变”,这是一种保守性改变的突变。本说明书中的编码多肽的所有碱基序列也包括所述核酸的所有可能的沉默改变。沉默突变包括其中编码核酸(nuclear acid)不改变的“沉默替换”,和核酸原本不编码氨基酸的情况。当某种核酸编码氨基酸时,沉默突变与沉默替换有相同含义。在本说明书中,“沉默替换”表示在碱基序列中用编码相同氨基酸的另一个碱基序列替换编码一种氨基酸的碱基序列。基于遗传密码简并性的现象,在多种碱基序列编码某种氨基酸(如甘氨酸)的情况下,这种沉默替换是可能的。因此,含由沉默替换产生的碱基序列编码的氨基酸序列的多肽具有与原始多肽相同的氨基酸序列。因此,除了本发明针对的修饰(进行替换使得所述α-葡聚糖磷酸化酶在选自下组的至少一个位置具有与所述天然α-葡聚糖磷酸化酶氨基酸残基不同的氨基酸残基:对应所述基序序列1L或1H中第4位的位置、对应所述基序序列2中第4位的位置、对应所述基序序列3L或3H中第7位的位置、或对应SEQ ID NO:2的氨基酸序列中第39位苯丙氨酸(F39)的位置、对应第135位天冬酰胺(N135)的位置和对应第706位苏氨酸(T706)的位置)以外,本发明所述耐热化α-葡聚糖磷酸化酶可以包括在碱基序列水平的沉默替换。在本领域中,可以理解核酸中的每个密码子(不包括ATG和TGG,其中ATG是通常编码甲硫氨酸的唯一一个密码子,TGG是通常编码色氨酸的唯一一个密码子)可以修饰以产生功能相同的分子。因此,编码多肽的核酸的每个沉默突变也隐含在每种所述序列中。优选的,可以进行这些改变使得避免替换半胱氨酸,半胱氨酸是大大影响多肽构象的氨基酸。
可以改变编码本发明耐热化α-葡聚糖磷酸化酶的碱基序列,使得与将要导入序列供表达的生物体的密码子使用偏好相一致。密码子使用偏好反映所述生物中高表达基因的使用偏好。例如,当意图在大肠杆菌中表达时,可根据公开的密码子使用偏好表(如Sharp,et al.,Nucleic Acids Research 16,No.17,p.8207(1988))对所述序列进行大肠杆菌表达的优化。
(2.3制备表达载体)
使用含上述修饰的碱基序列的核酸分子制备表达载体。使用特定核酸序列制备表达载体的方法对本领域技术人员是公知的。
当在本说明书中提及核酸分子时,“载体”表示可转移目标碱基序列到目标细胞中的核酸分子。这些载体的实例包括可在目标细胞中自主复制或可整合到目标细胞染色体中、并在适于转录修饰碱基序列的位置有启动子的载体。在本说明书中,所述载体可以是质粒。
如此处所用,所述“表达载体”表示可在目标细胞中表达修饰碱基序列(即编码修饰的α-葡聚糖磷酸化酶的碱基序列)的载体。除了修饰碱基序列以外,表达载体还含有多种调节元件如调节表达的启动子,如果必要,还含有在目标细胞中复制和选择重组体所必需的因子(如复制起点(ori)和诸如药物抗性基因的选择标记)。在表达载体中,修饰的碱基序列可操作的连接,使得它可以被转录和翻译。调节元件包括启动子、终止子和增强子。此外,当意图将表达酶分泌到细胞外时,编码分泌信号肽的碱基序列以正确的读码框连接到修饰的碱基序列上游。本领域技术人员公知,用于导入特定生物(如细菌)中的表达载体类型和用于所述表达载体的调节元件和其它因子的种类都可以根据目标细胞而改变。
如此处所用,所述“终止子”是位于蛋白质编码区域下游的序列,参与将碱基序列转录成mRNA的转录过程的终止,参与添加多聚A序列。已知所述终止子在mRNA稳定性方面影响基因表达水平。
如此处所用,所述“启动子”表示DNA上确定基因的转录起始位点并直接调节转录频率的区域,同时还是结合RNA聚合酶并因此启动转录的碱基序列。因为在用DNA分析软件预测基因组碱基序列中的蛋白质编码区域时,在很多情况下启动子区域通常是推断的蛋白质编码区域上游约2kbp或更近的区域,启动子区域是可以推断的。推断性启动子区域随每个结构基因而变化,并通常非限制性的位于结构基因上游,还可以在结构基因下游。推断性启动子区域优选位于第一个外显子翻译起始位点上游约2kbp或更近。
如此处所用,所述“增强子”可用于增强目标基因的表达效率。这样的增强子在本领域公知。可以使用多种增强子,但只可以使用一种,或可以完全不用。
如此处所用,“可操作的连接”表示将期望碱基序列放置于转录和翻译调节序列(如启动子、增强子等)或实现表达的翻译调节序列(即操作)的控制之下。为了使启动子与基因可操作的连接,通常将启动子置于所述基因的即上游,但不必要将启动子置于与所述基因临近的位置。
为了将修饰核酸序列与前述调节元件可操作的连接,在有些情况下要加工目标α-葡聚糖磷酸化酶基因。实例包括启动子和编码区之间距离太长而预计转录效率降低的情况、核糖体结合位点和翻译起始密码子之间距离不合适的情况等。所述加工含义的实例包括用限制酶消化、用核酸外切酶如Bal31和ExoIII消化或用单链DNA如M13或PCR引入定点突变。
(2.4耐热性α-葡聚糖磷酸化酶的表达)
然后,将如上述制备的表达载体导入细胞,因而表达耐热性α-葡聚糖磷酸化酶。
在本说明书中,酶的“表达”指编码所述酶的碱基序列在体内或体外的转录和翻译,以及所编码酶的生成。
导入表达载体的细胞(也称为宿主)包括原核和真核细胞。考虑多种条件如表达α-葡聚糖磷酸化酶的难易、培养的难易、生长速率和安全性,可以容易的选择导入表达载体的细胞。例如当使用α-葡聚糖磷酸化酶来合成高分子量直链淀粉时,因为优选α-葡聚糖磷酸化酶不含淀粉酶污染,优选使用不产生淀粉酶或仅产生低水平淀粉酶的细胞。这样的细胞的实例包括微生物,如细菌和真菌。更优选的细胞的实例包括中温性微生物(例如大肠杆菌、枯草杆菌)。在本说明书中,所述“中温性微生物”是具有正常温度环境生长温度的微生物,具体指最佳生长温度20℃-40℃的微生物。细胞可以是如微生物细胞,或可以是植物或动物细胞。依赖于待用细胞,本发明的酶可以是经历翻译后加工的酶。植物包括但不限于双子叶植物,和单子叶植物如水稻、小麦、大麦和玉米。谷类如水稻具有在种子中积累储藏蛋白的性质,使用储藏蛋白系统,可以表达所述谷类使得本发明的耐热化α-葡聚糖磷酸化酶在种子中积累(见日本特开平公开No.2002-58492的说明书)。
在本发明方法中,将表达载体导入细胞中的技术可以是本领域已知的任一种技术。这种技术的实例例如包括转化、转导和转染。这种导入核酸分子的技术在本领域公知,并且是常规技术,例如描述于Ausubel F.A.,et al.ed.(1988),Current Protocols inMolecular Biology,Wiley,New York,NY;Sambrook J,et al.(1987)Molecular Cloning:ALaboratory Manual,2nd Ed.,Cold Spring Harbor Laboratory Press,Cold Spring Harbor,NY,和Bessatsu Jikkenkagaku“Idenshidounyu & Hatsugen kaiseki jikkenhou”,Yodosha,1997。
当使用植物细胞作为细胞时,使转化体重新分化成组织或植物的方法在本领域公知。这种方法的实例描述如下:Rogers,et al.,Methods in Enzymology 118:627-640(1986);Tabata,et al.,Plant Cell Physiol.,28:73-82(1987);Shaw,Plant Molecular Biology:A Practical Approach.IRL press(1988);Shimamoto,et al.,Nature 338:274(1989);和Maliga,et al.,Methods in Plant Molecular Biology:A Laboratory course.Cold SpringHarbor Laboratory Press(1995)。转化木本植物的方法描述于Molecular Biology ofWoody Plants(Vol.I,II)(ed.S.Mohan Jain,Subhash C.Minocha),Kluwer AcademicPublishers,(2000)。此外,转化木本植物的方法例如详细描述于Plant Cell Reports(1999)19:106-110。因此,根据目标转基因植物,本领域技术人员可以适当的使用前述公知方法使转化体重新分化。目标基因导入如此所得转基因植物,并且可以用已知方法如Northern印迹和Western印迹分析或其它公知常规技术确认基因的导入。
通过培养已导入表达载体并获得表达耐热化α-葡聚糖磷酸化酶能力的细胞(也称转化细胞),可以在细胞中表达耐热化α-葡聚糖磷酸化酶。培养转化细胞的条件可根据待使用宿主细胞种类和表达载体中表达调节因子的种类适当选择。例如,通常使用振荡培养方法。
不具有限定用于培养转化细胞的培养基,只要所使用细胞生长并能表达目标耐热化α-葡聚糖磷酸化酶即可。除了碳源和氮源以外,如果必要可在培养基中单独或适当混合使用无机盐如磷酸盐、Mg2+、Ca2+、Mn2+、Fe2+、Fe3+、Zn2+、Co2+、Ni2+、Na+、K+等。此外,如果必要,可以添加培养转化细胞或表达目标耐热化α-葡聚糖磷酸化酶所必需的多种无机物或有机物。
可以选择转化细胞的培养温度使得适于生长待使用转化细胞。通常,温度在15℃-60℃之间。使连续培养转化细胞的时间足以表达耐热化α-葡聚糖磷酸化酶。
当使用带诱导型启动子的表达载体时,可通过加入诱导剂、改变培养温度和调节培养基成分来控制表达。例如,当使用带乳糖诱导型启动子的表达载体时,可通过加入异丙基-β-D-硫代半乳糖苷(IPTG)诱导表达。
(2.5回收耐热化α-葡聚糖磷酸化酶)
然后可以回收所表达耐热化α-葡聚糖磷酸化酶。例如,当在转化细胞中生成所表达耐热化α-葡聚糖磷酸化酶时,通过离心或过滤培养物从转化细胞培养物中回收细胞。所回收细胞悬于合适缓冲液中,并用常规方法(超声、French press、溶菌酶处理)破碎而获得粗酶液。进而,通过用适当组合的常规酶纯化方法如离心、层析、膜分离、电泳和盐析来纯化所述粗酶液,从而获得粗酶液或具有更高比活性的纯化酶。当不含水解葡聚糖的酶如α-淀粉酶时,可以直接使用粗酶,例如用于制备高分子量葡聚糖。
通过如上述生产耐热化α-葡聚糖磷酸化酶,可以相当大的提高天然α-葡聚糖磷酸化酶的耐热性。此外,所表达耐热化α-葡聚糖磷酸化酶可以利用这种耐热性简单纯化。简单的说,通过在约60℃热处理含耐热化α-葡聚糖磷酸化酶的细胞提取物,使污染酶不再溶解。通过离心所述不溶物而除去它们,并进行透析处理,从而获得纯化的耐热化α-葡聚糖磷酸化酶。

本发明耐热化α-葡聚糖磷酸化酶在选自下组的至少一个位置具有与所述天然α-葡聚糖磷酸化酶氨基酸残基不同的氨基酸残基:对应SEQ ID NO:2的氨基酸序列中第39位苯丙氨酸(F39)的位置;对应SEQ ID NO:2的氨基酸序列中第135位天冬酰胺(N135)的位置;和对应SEQ ID NO:2的氨基酸序列中第706位苏氨酸(T706)的位置。,除了这些位置上的氨基酸替换以外,本发明耐热化α-葡聚糖磷酸化酶还可以含有相对于天然α-葡聚糖磷酸化酶氨基酸序列而言缺失、替换或添加了一个或几个氨基酸的氨基酸序列。

天然α-葡聚糖磷酸化酶的前述三个位置被认为在α-葡聚糖磷酸化酶立体结构中与周围氨基酸相互作用形成立体的部分结构,使所述酶去稳定化。通过将这些位置的残基改变成另一个氨基酸残基,酶被稳定化,并且耐热性提高。此外,因为这些位置的残基在立体结构上与周围氨基酸残基相互作用,替换所述氨基酸残基具有意料之外重要的显著影响。例如,对于马铃薯L型α-葡聚糖磷酸化酶,用其它残基替换F39位置的F具有意料之外重要的显著结果。此外,例如,对于马铃薯来源H型α-葡聚糖磷酸化酶,对应F39位置的氨基酸是Y,用其它氨基酸替换Y具有意料之外重要的显著影响。

在根据本发明的方法中,为制备耐热化α-葡聚糖磷酸化酶,除了本发明目的的改变以外(这种替换使得α-葡聚糖磷酸化酶在选自下组的至少一个位置具有与所述天然α-葡聚糖磷酸化酶氨基酸残基不同的氨基酸残基:对应SEQ ID NO:2的氨基酸序列中第39位苯丙氨酸(F39)的位置;对应SEQ ID NO:2的氨基酸序列中第135位天冬酰胺(N135)的位置;和对应SEQ ID NO:2的氨基酸序列中第706位苏氨酸(T706)的位置)还可以进行氨基酸替换、添加、缺失或修饰。氨基酸替换表示用一种氨基酸替换另一种氨基酸。氨基酸添加表示在原氨基酸序列的任意位置插入一个或更多,例如1-10个、优选1-5个、更优选1-3个氨基酸。氨基酸缺失表示从原氨基酸序列的任意位置去除一个或更多,例如1-10个、优选1-5个、更优选1-3个氨基酸。氨基酸修饰的实例包括但不限于酰胺化、羧化、硫酸化、卤化、烷基化、糖基化、磷酸化、羟化和酰化(如乙酰化)。本发明耐热化α-葡聚糖磷酸化酶可以通过肽合成方法合成,在这种情况下待替换或添加的氨基酸可以是天然氨基酸、非天然氨基酸或氨基酸类似物。优选天然氨基酸。
本发明耐热化α-葡聚糖磷酸化酶可以是具有α-葡聚糖磷酸化酶相同酶活性的酶类似物。如此处所用,术语“酶类似物”表示一种实体,它是与天然酶不同的化合物(compound),但在至少一种化学功能或生物学功能上与天然酶等价。因此,所述酶类似物包括相对于起始天然酶添加或替换一个或更多个氨基酸类似物的实体。所述酶类似物具有这样的添加或替换,使得它的功能(如α-酸化酶活性或耐热性)与起始天然酶的功能基本相同或更好。这样的酶类似物可以用本领域公知的技术制备。因此,所述酶类似物可以是含氨基酸类似物的聚合物。在本说明书中,除非另外说明,所述“酶”包括这种酶类似物。

除了所述目的性修饰以外,耐热化α-葡聚糖磷酸化酶还可以包括相对于天然α-葡聚糖磷酸化酶氨基酸序列而言一个或几个或更多个氨基酸替换、添加或缺失引起的修饰,这样的耐热化α-葡聚糖磷酸化酶也在本发明范围内。包括一个或几个或更多个氨基酸替换、添加或缺失的这种耐热化α-葡聚糖磷酸化酶例如可以根据描述于下文的方法制备:Molecualr Cloning,A Laboratory Manual,Second Edition,Cold Spring HarborLaboratory Press(1989),Current Protocols in Molecular Biology,Supplement 1-38,JohnWiley & Sons(1987-1997),Nucleic Acids Research,10,6487(1982),Proc.Natl.Acad.Sci.,USA,79,6409(1982),Gene,34,315(1985),Nucleic Acids Research 13,443(1985),Proc.Natl.Acad.Sci.,USA,81,5662(1984),Science,224,1431(1984),PCT WO85/00817(1985),Nature,316,601(1985)。
根据本发明的耐热化α-葡聚糖磷酸化酶可用本领域公知的方法制备。例如,根据本发明的所述耐热化α-葡聚糖磷酸化酶中氨基酸的缺失、替换或添加可以通过本领域公知的定点突变技术进行。定点突变程序在本领域公知。例如,见Nucl.Acid Research,Vol.10,pp.6487-6500(1982)。
在本说明书中,当用于耐热化α-葡聚糖磷酸化酶时,所述“一个或几个或更多个氨基酸的替换、添加或缺失”或所述“至少一个氨基酸的替换、添加或缺失”表示一定数目的替换、添加或缺失,这种改变程度使α-葡聚糖磷酸化酶的酶活性不丧失,优选所述酶活性与标准品(如天然α-葡聚糖磷酸化酶)等价或超过标准品。本领域技术人员可以容易的选择具有期望性质的耐热化α-葡聚糖磷酸化酶。另外,目标性耐热化α-葡聚糖磷酸化酶可以直接化学合成。这种化学合成方法在本领域公知。
由此制备的本发明耐热化α-葡聚糖磷酸化酶优选与第一种(天然)α-葡聚糖磷酸化酶(优选马铃薯L型α-葡聚糖磷酸化酶)的氨基酸序列具有约40%、更优选约45%、更优选约50%、更优选约55%、更优选约60%、更优选约65%、更优选约70%、更优选约75%、更优选约80%、更优选约85%、更优选约90%、更优选约95%和最更优选约99%一致性。
设计前述改变时,可以考虑氨基酸的疏水性指数。赋予蛋白质相互作用性生物功能的疏水性氨基酸指数显著性在本领域公知(Kyte.J and Doolittle,R.F.J.Mol.Biol.157(1):105-132,1982)。氨基酸的疏水性对所产生蛋白的二级结构有贡献,并限定所述蛋白质和其它分子(如酶、底物、受体、DNA、抗体、抗原等)之间的相互作用。基于疏水性和带电性质,氨基酸被指定一个疏水性指数。它们是:异亮氨酸(+4.5);缬氨酸(+4.2);亮氨酸(+3.8);苯丙氨酸(+2.8);半胱氨酸/胱氨酸(+2.5);甲硫氨酸(+1.9);丙氨酸(+1.8);甘氨酸(-0.4);苏氨酸(-0.7);丝氨酸(-0.8);色氨酸(-0.9);酪氨酸(-1.3);脯氨酸(-1.6);组氨酸(-3.2);谷氨酸(-3.5);谷氨酰胺(-3.5);天冬氨酸(-3.5);天冬酰胺(-3.5);赖氨酸(-3.9);精氨酸(-4.5)。
本领域公知用具有相似疏水性指数的另一种氨基酸替换某种氨基酸,从而可以产生仍然具有相似生物功能的蛋白质(如酶活性等价的蛋白质)。在这种氨基酸替换中,疏水性指数优选在±2以内,更优选在±1以内,进一步优选在±0.5以内。本领域中可以理解基于疏水性的这种氨基酸替换是有效率的。如USP No.4,554,101中描述,给氨基酸残基指定以下亲水性指数:精氨酸(+3.0);赖氨酸(+3.0);天冬氨酸(+3.0±1);谷氨酸(+3.0±1);丝氨酸(+0.3);天冬酰胺(+0.2);谷氨酰胺(+0.2);甘氨酸(0);苏氨酸(-0.4);脯氨酸(-0.5±1);丙氨酸(-0.5);组氨酸(-0.5);半胱氨酸(-1.0);甲硫氨酸(-1.3);缬氨酸(-1.5);亮氨酸(-1.8);异亮氨酸(-1.8);酪氨酸(-2.3);苯丙氨酸(-2.5);色氨酸(-3.4)。可以理解,氨基酸可以用具有相似亲水性指数的另一种氨基酸替换,且仍然能是生物学等价的。在这种氨基酸替换中,所述亲水性指数优选在±2以内,更优选在±1以内,进一步优选在±0.5以内。

(3.3评价合成直链淀粉能力的方法)
本发明耐热化α-葡聚糖磷酸化酶具有一种特性,它具有合成葡聚糖(尤其是直链淀粉)的能力,所述葡聚糖的重均分子量优选是约60kDa或更高,更优选约100kDa或更高,进一步优选约150kDa或更高,进一步优选约200kDa或更高,进一步优选约250kDa或更高,进一步优选约300kDa或更高,进一步优选约350kDa或更高,进一步优选约400kDa或更高,进一步优选约450kDa或更高,进一步优选约500kDa或更高,进一步优选约550kDa或更高,进一步优选约600kDa或更高,最优选约650kDa或更高。重均分子量约5kDa到约599kDa的葡聚糖几乎不溶于水,而重均分子量约600kDa或更高的葡聚糖有可溶于水的特别优点。通过本发明耐热化α-葡聚糖磷酸化酶合成葡聚糖的重均分子量没有具体上限,但可以极高生产率合成最高为1000kDa、最高为10000kDa、最高为100000kDa的葡聚糖。
所述“合成重均分子量为60kDa或更高的直链淀粉的能力”表示当通过使用40μM麦芽四糖、250mM葡萄糖-1-磷酸、200mM乙酸盐缓冲液(pH5.5)和4U/ml耐热化α-葡聚糖磷酸化酶(纯化酶)反应液在37保温18小时合成直链淀粉时,其重均分子量是60kDa或更高。类似的定义合成具有其它重均分子量直链淀粉的能力,例如,“合成重均分子量为600kDa或更高的直链淀粉的能力”表示当在此条件下合成直链淀粉时,其重均分子量是600kDa或更高。
例如可以通过以下方法测定直链淀粉的重均分子量。
首先,将所合成直链淀粉完全溶解于1N氢氧化钠,用适量盐酸中和,使用差示折光计和多角光散射检测器将一小份约30-300μg的直链淀粉进行凝胶过滤层析,从而获得平均分子量。
更具体的,使用Shodex SB806M-HQ(SHOWA DENKO K.K.制造)作为柱子,使用依次连接的多角光散射检测器(DAWN-DSP,Wyatt Technology制造)和差示折光计(Shodex RI-71,SHOWA DENKO K.K.制造)作为检测器。柱子保持在40℃,并使用0.1M硝酸钠溶液以1mL/min流速作为洗脱剂。用数据分析软件(商品名ASTRA,Wyatt Technology制造)收集所得信号,并用相同软件分析,从而得到重均分子量。
(3.4评价保存稳定性的方法)
与天然α-葡聚糖磷酸化酶比较,根据本发明的所述耐热化α-葡聚糖磷酸化酶优选具有更高保存稳定性。在本说明书中,所述“保存稳定性更高”表示与天然α-葡聚糖磷酸化酶比较所述酶几乎不被降解的情况。
在一个实施方案中,保存稳定性表示当保存在4℃时的稳定性。在此情况下,当根据本发明的所述耐热化α-葡聚糖磷酸化酶纯化后在4℃保存一段时间时,所述酶蛋白的分子量几乎等于纯化后即刻的分子量。一般来说,当天然α-葡聚糖磷酸化酶在4℃长期保存时会降解,与纯化后即刻比较酶蛋白的分子量降低。本发明的耐热化α-葡聚糖磷酸化酶优选在4℃保存1个月、更优选在4℃保存3个月、最优选在4℃保存5个月后,它具有与纯化后即刻大致相等的分子量。
另一方面,保存稳定性表示保存在37℃时的稳定性。在此情况下,当根据本发明的所述耐热化α-葡聚糖磷酸化酶纯化后在37℃保存一段时间时,所述酶蛋白的分子量与纯化后即刻的分子量大致相等。一般来说,当天然α-葡聚糖磷酸化酶在37℃长期保存时会降解,并且与纯化后即刻比较酶蛋白的分子量降低。另一方面,本发明的耐热化α-葡聚糖磷酸化酶优选在37℃保存4天、更优选在37℃保存7天、最优选在37℃保存10天后,它具有与纯化后即刻大致相等的分子量。
当然,本发明的耐热化α-葡聚糖磷酸化酶可以保存在正常用于保存的任意温度。用于保存的温度可以是约4℃到约37℃之间的任意温度(如约4℃、约5℃、约10℃、约20℃、约25℃、约37℃等)。
可以用本领域已知的任意方法评价保存稳定性。例如,纯化后即刻的酶蛋白和已在预定温度保存一段时间的酶蛋白进行聚丙烯酰胺凝胶电泳(Native-PAGE),并通过比较这些酶蛋白的分子量评价稳定性。
(4.用本发明的酶制备葡聚糖的方法)
本发明耐热化α-葡聚糖磷酸化酶可有利地用于合成葡聚糖的方法。用本发明耐热化α-葡聚糖磷酸化酶合成葡聚糖的方法可以是本领域已知的合成葡聚糖的任意方法。但本发明的α-葡聚糖磷酸化酶优选用于同时用蔗糖磷酸化酶和α-葡聚糖磷酸化酶使蔗糖和引发剂反应的方法(也称SP-GP方法)中。所述SP-GP方法具有可使用廉价底物生产线性葡聚糖的优点。
本发明合成葡聚糖的方法包括使反应液发生反应以产生葡聚糖,所述反应液中含有本发明的所述耐热化α-葡聚糖磷酸化酶、蔗糖磷酸化酶、蔗糖、引发剂,和无机磷酸或葡萄糖-1-磷酸。
本发明合成葡聚糖的方法可以是不基于SP-GP方法的方法。在这种方法的情况下,本发明合成葡聚糖的方法包括使反应液发生反应以产生葡聚糖,所述反应液中含有本发明的所述耐热化α-葡聚糖磷酸化酶、引发剂和葡萄糖-1-磷酸。
在本说明书中,所述“葡聚糖”表示一种糖,其中含D-葡萄糖作为组成单元,并具有以α-1,4-糖苷键连接的至少两个糖单元或更多个糖单元。葡聚糖可以是线性、支链或环状分子。线性葡聚糖与α-1,4-葡聚糖有相同含义。在线性葡聚糖中,糖单元之间只用α-1,4-糖苷键连接。含有一个或更多α-1,6-糖苷键的葡聚糖是支链葡聚糖。某种程度上葡聚糖优选含有线性节段。无分支的线性葡聚糖较为优选。
某些情况下葡聚糖优选具有小数目的(即α-1,6-糖苷键的数目)分支。这种情况下,分支数目代表性的是0-10000,优选0-1000,更优选0-500,进一步优选0-100,进一步优选0-50,进一步优选0-25,进一步优选0。
本发明的葡聚糖中,将α-1,6-糖苷键当作1,α-1,4-糖苷键数目相对于α-1,6-糖苷键数目的比值优选是1-10000,更优选2-5000,进一步优选5-1000,进一步优选10-500。
α-1,6-糖苷键可以随机分布于葡聚糖中,也可以均匀分布。分布程度使得在葡聚糖中优选形成5个或更多糖单元的线性部分。
葡聚糖可以只由D-葡聚糖构成,或可以是一定程度修饰的衍生物,这种修饰程度使这种葡聚糖的性质不变差。所述葡聚糖优选不修饰。
葡聚糖的代表性分子量是约8×103或更高,优选约1×104或更高,更优选约5×104或更高,进一步优选约1×105或更高,进一步优选约6×105或更高。葡聚糖的代表性分子量是约1×108或更低,优选约3×107或更低,更优选约1×107或更低,进一步优选约5×106或更低,进一步优选约1×106或更低。在本发明中,除非另外说明,葡聚糖的分子量指重均分子量。
本领域技术人员容易理解,通过适当选择用于本发明生产方法的底物量、酶量、反应时间等可以获得具有期望分子量的葡聚糖。
具有极佳生产率的SP-GP法描述于国际公开WO 02/097107小册子。
在本发明生产方法中,例如,耐热化α-葡聚糖磷酸化酶、蔗糖磷酸化酶、蔗糖、引发剂、无机磷酸或葡萄糖-1-磷酸、缓冲剂和溶解它的溶剂被用作主要材料。通常这些材料在反应开始时全部加入,其中的任何材料还可以在反应过程中加入。在本发明的生产方法中,如果必要,可以使用选自脱支酶、分支酶、4-α-葡聚糖基转移酶和糖原脱支酶的酶。根据葡聚糖的期望结构,可以在本发明生产方法开始时或在反应中途将选自脱支酶、分支酶、4-α-葡聚糖基转移酶和糖原脱支酶的酶加入反应溶液中。
在本说明书中,所述“蔗糖磷酸化酶”表示将蔗糖的α-糖苷基转移到磷酸基上以进行磷酸解作用的任何酶。由蔗糖磷酸化酶催化的反应由以下方程式表示:
自然界中多种生物含有蔗糖磷酸化酶。产生蔗糖磷酸化酶的实例包括但不限于链球菌属的细菌(如嗜热链球菌、转糖链球菌、肺炎链球菌和缓症链球菌)、肠膜明串珠菌、假单胞菌属、梭菌属、Pullularia pullulans、木醋杆菌、农杆菌属、Synecococcussp.、大肠杆菌、单核细胞增生利斯特氏菌、青春双歧杆菌、黑曲霉、链孢霉、Sclerotineaescerotiorum和衣藻。
蔗糖磷酸化酶可以来源于产生蔗糖磷酸化酶的任何生物。蔗糖磷酸化酶优选具有一定程度的耐热性。更优选当蔗糖磷酸化酶单独存在时具有更高耐热性。例如在存在4%蔗糖下在55℃加热蔗糖磷酸化酶30分钟时,优选保留加热前蔗糖磷酸化酶活性的20%或更多。蔗糖磷酸化酶优选来源于选自转糖链球菌、肺炎链球菌、肠膜明串珠菌、酒类酒球菌、长双岐杆菌、葡萄土壤杆菌、嗜糖假单胞杆菌、大肠杆菌和无害利斯特氏菌的细菌,更优选可以来源于选自转糖链球菌、肺炎链球菌、肠膜明串珠菌和酒类酒球菌的细菌,进一步优选可以来源于转糖链球菌或肺炎链球菌。
蔗糖是分子量约342的二糖,用C12H22O11表示。蔗糖存在于具有光合作用能力的所有植物中。蔗糖可以从植物中分离,或可以化学合成。从成本观点来看,优选从植物分离蔗糖。含大量蔗糖的植物的实例包括甘蔗和甜菜。甘蔗汁含约20%蔗糖。甜菜汁含约10-15%蔗糖。可以在从含蔗糖的植物液或汁到纯化蔗糖的任意纯化阶段提供蔗糖。
用于本发明生产方法的耐热化α-葡聚糖磷酸化酶和蔗糖磷酸化酶可分别用于反应,甚至当固定化时也是如此,而无论是纯化酶还是粗酶,并且反应形式可以是批次形式或连续形式。作为固定化方法,可以使用载体结合方法(如共价结合方法、离子结合方法或物理吸附方法)、交联方法或包合方法(格形式或微胶囊形式)。
引发剂的实例包括低聚麦芽糖、直链淀粉、支链淀粉、糖原、糊精、普鲁分支葡聚糖、偶联糖、淀粉,及其衍生物。
在本说明书中,无机磷酸指SP反应中能提供磷酸根底物的物质。在本说明书中,磷酸根底物表示用作葡萄糖-1-磷酸的磷酸部分原材料的物质。人们认为,在由蔗糖磷酸化酶催化的蔗糖磷酸解中,无机磷酸以磷酸根离子形式起底物作用。因为这种底物一般在本领域称为无机磷酸,在本说明书中这种底物也被称为无机磷酸。无计磷酸包括磷酸和磷酸的无机盐。通常,无机磷酸在含阳离子如碱金属离子的水中使用。在此情况下,因为磷酸、磷酸盐和磷酸根离子处于平衡状态,不可能区分磷酸和磷酸盐。因此,为了方便,磷酸和磷酸盐通称无机磷酸。在本发明中,无机磷酸优选是磷酸的的任意金属盐,更优选是磷酸的碱金属盐。无机磷酸的优选具体实例包括磷酸二氢钠、磷酸氢二钠、磷酸三钠、磷酸二氢钾、磷酸氢二钾、磷酸三钾、磷酸(H3PO4)、磷酸二氢铵和磷酸氢二铵。
SP-GP反应体系中在反应起始时可以含有仅一种或多种无机磷酸。
例如可以通过物理、化学或酶促反应降解磷酸缩合物如多磷酸(如焦磷酸、三磷酸和四磷酸)或其盐、并将此加入反应液中来提供无机磷酸。
在本说明书中,葡萄糖-1-磷酸指葡萄糖-1-磷酸(C6H13O9P)及其盐。葡萄糖-1-磷酸优选是狭义葡萄糖-1-磷酸(C6H13O9P)的任意金属盐,更优选是葡萄糖-1-磷酸(C6H13O9P)的任意碱金属盐。葡萄糖-1-磷酸的优选具体实例包括葡萄糖-1-磷酸二钠、葡萄糖-1-磷酸二钾和葡萄糖-1-磷酸(C6H13O9P)。在本说明书中,没有在括号内标出化学式的葡萄糖-1-磷酸表示广义的葡萄糖-1-磷酸,即狭义葡萄糖-1-磷酸(C6H13O9P)及其盐。
SP-GP反应体系中在反应起始时可以含有仅一种或多种葡萄糖-1-磷酸。
根据本发明生产葡聚糖的方法中,当在产物中产生分支时,如当使用含α-1,6-糖苷键的起始材料时,如果必要可使用脱支酶。
可用于本发明的脱支酶是能切割α-1,6-糖苷键的酶。脱支酶分成两类,良好作用于支链淀粉和糖原的异淀粉酶(EC3.2.1.68),和作用于支链淀粉、糖原和普鲁分支葡聚糖的α-糊精内-1,-α-糖苷酶(也称支链淀粉酶(pullulanase))(EC3.2.1.41)。
脱支酶存在于微生物、细菌和植物中。产生脱支酶的微生物实例包括酿酒酵母菌和衣藻属物种。产生脱支酶的细菌实例包括短芽孢杆菌、Bacillus acidopullulyticus、浸麻芽孢杆菌(Bacillus macerans)、嗜热脂肪芽孢杆菌(Bacillus stearothermophilus)、环状芽孢杆菌、水生栖热菌(Thermus aquaticus)、肺炎克雷伯氏菌、嗜温高温放线菌(Thermoactinomyces thalpophilus)、Thermoanaerobacter ethanolicus和Pseudomonasamyloderamosa。产生脱支酶的植物实例包括马铃薯、甘薯、玉米、水稻、小麦、大麦、燕麦和甜菜。产生脱支酶的生物不限于以上实例。
根据本发明的方法中,当希望在产物中产生分支时,如果必要可使用分支酶。
可用于本发明的分支酶是可转移一部分α-1,4-葡聚糖链到该α-1,4-葡聚糖链的某个葡萄糖残基上的第6位从而形成分支的酶。分支酶也称1,4-α-葡聚糖分支酶、分支产生酶或Q酶。
分支酶存在于微生物、动物和植物中。产生分支酶的微生物实例包括嗜热脂肪芽孢杆菌、枯草芽孢杆菌、热容芽孢杆菌(Bacillus caldolyticus)、Bacillus lichecniformis、解淀粉芽孢杆菌(Bacillus amyloliquefaciens)、凝结芽孢杆菌(Bacillus coagulans)、Bacillus caldovelox、Bacillus thermocatenulatus、Bacillus smithii、巨大芽孢杆菌(Bacillusmegaterium)、短芽孢杆菌、Alkalophilic Bacillus sp.、天蓝链霉菌(Streptomycescoelicolor)、Aquifex aeolicus、蓝藻物种(Synechosystis sp.)、大肠杆菌、根癌土壤杆菌、水生栖热菌、Rhodothermus obamensis、粗糙脉孢菌(Neurospora crassa)和酵母。产生分支酶的动物的实例包括诸如人、兔、大鼠和猪的哺乳动物。产生分支酶的植物实例包括藻类;块茎和根作物如马铃薯、甘薯、薯蓣和木薯;蔬菜如菠菜;谷类如玉米、水稻、小麦、大麦、黑麦和粟;与豆类如豌豆、大豆、赤豆和杂色菜豆。产生分支酶的生物不限于以上实例。
在根据本发明的方法中,当在产物中产生环状结构时,如果必要可以使用4-α-葡聚糖转移酶。
可用于本发明的4-α-葡聚糖转移酶也称歧化酶、D-酶或淀粉麦芽糖酶,是可催化低聚麦芽糖的糖转移反应(歧化反应)的酶。4-α-葡聚糖转移酶是将葡萄糖基团或麦芽糖基或低聚麦芽糖基单元从供体分子的非还原端转移到受体分子的非还原端的酶。因此酶反应导致最初给定的低聚麦芽糖的聚合程度歧化。当供体分子和受体分子相同时,引起分子内转移,并因而得到有环状结构的产物。
4-α-葡聚糖转移酶存在于微生物和植物中。产生4-α-葡聚糖转移酶的微生物实例包括Aquifex aeolicus、肺炎链球菌、丁酸杆菌(Clostridium butylicum)、耐辐射奇异球菌(Deinococcus radiodurans)、流感嗜血杆菌、结核分枝杆菌、Thermococcus litralis、海栖热袍菌(Thermotoga maritima)、Thermotoga neapolitana、鹦鹉热衣原体(Chlamydiapsittaci)、热球菌属物种(Pyrococcus sp.)、嗜热网球菌(Dictyoglomus thermophilum)、伯氏疏螺旋体(Borrelia burgdorferi)、蓝藻、大肠杆菌和水生栖热菌。产生4-α-葡聚糖转移酶的植物实例包括块茎和根作物如马铃薯、甘薯、薯蓣和木薯;谷类如玉米、水稻和小麦;与豆类如豌豆和大豆。产生4-α-葡聚糖转移酶的生物不限于以上实例。
在根据本发明的方法中,当在产物中产生环状结构时,如果必要可以使用糖原脱支酶。
可用于本发明的糖原脱支酶是具有两种活性的酶,即α-1,6-糖苷酶活性和4-α-葡聚糖转移酶活性。由于糖原脱支酶具有4-α-葡聚糖转移酶活性,而获得具有环状结构的产物。
糖原脱支酶存在于微生物和动物。产生糖原脱支酶的微生物实例包括酵母。产生糖原脱支酶的动物实例包括哺乳动物如人、兔、大鼠和猪。产生糖原脱支酶的生物不限于以上实例。
用于本发明生产方法的溶剂可以是任何溶剂,只要它不破坏蔗糖磷酸化酶和α-葡聚糖磷酸化酶的酶活性。
只要产生葡聚糖的反应可以发生,溶剂就不必要完全溶解用于根据本发明生产方法的物质。例如,当酶由固相载体携带时,酶不必要溶于溶剂。进而,不必所有反应物质如蔗糖都溶解,只要部分物质的溶解程度可使反应进行就足够了。
代表性的溶剂是水。溶剂可以是细胞裂解液中的水,在制备蔗糖磷酸化酶或α-葡聚糖磷酸化酶时同时伴随蔗糖磷酸化酶或α-葡聚糖磷酸化酶。
在含有α-葡聚糖磷酸化酶、蔗糖磷酸化酶、蔗糖、引发剂、和无机磷酸或葡萄糖-1-磷酸的溶液中,还可以含有任何其它物质,只要不阻碍所述蔗糖磷酸化酶和蔗糖之间相互作用以及所述α-葡聚糖磷酸化酶与所述引发剂之间相互作用即可。这种物质的实例包括缓冲剂、产生α-葡聚糖磷酸化酶的微生物(如细菌、真菌)成分、产生蔗糖磷酸化酶的微生物(如细菌、真菌)成分、盐和培养基成分。
待使用的这些物质的量是已知的,并且可由本领域技术人员适当选择。
在根据本发明的生产方法中,首先制备反应溶液。例如,可通过向合适溶剂中加入α-葡聚糖磷酸化酶、蔗糖磷酸化酶、固体蔗糖、引发剂、和无机磷酸或葡萄糖-1-磷酸来制备反应溶液。另外,可通过混合分别含有α-葡聚糖磷酸化酶、蔗糖磷酸化酶、蔗糖、引发剂、或无机磷酸或葡萄糖-1-磷酸的溶液来制备反应溶液。作为替代方案,可通过将其它固体成分与含有α-葡聚糖磷酸化酶、蔗糖磷酸化酶、蔗糖、引发剂、和无机磷酸或葡萄糖-1-磷酸中一些成分的溶液混合来制备反应溶液。如果必要,为调节pH的目的,可以向此反应溶液中加入任何缓冲剂,只要它不抑制酶反应即可。如果必要,可以向此反应溶液中加入选自脱支酶、分支酶、4-α-葡聚糖转移酶和糖原脱支酶的酶。
如果必要,然后通过本领域已知的方法加热反应溶液以使之反应。只要得到本发明的效果,反应温度可以是任何温度。当反应起始时反应溶液中的蔗糖浓度是约5%到约100%时,代表性的反应温度可以是约30℃到约75℃。优选的是,在此反应步骤中的溶液温度应使得预定反应时间后此反应溶液中所含蔗糖磷酸化酶和α-葡聚糖磷酸化酶中至少一种、优选两种酶活性保持反应前活性的约20%或更高,更优选约30%或更高。这种温度优选是约55℃到约75℃,更优选约60℃到约75℃,进一步优选约60℃到约70℃,特别优选约60℃到约65℃。
考虑到反应温度、反应产生葡聚糖的分子量和剩余酶活性,反应时间可以设定为任何时间。代表性反应时间是约1小时到约100小时,更优选约1小时到约72小时,进一步更优选约2小时到约36小时,最优选约2小时到约24小时。
以此方式,生产含葡聚糖的溶液。

本发明合成葡萄糖-1-磷酸的方法包括使含有本发明的耐热化α-葡聚糖磷酸化酶、葡聚糖和无机磷酸的反应液发生反应,以产生葡萄糖-1-磷酸。
用于根据本发明合成葡萄糖-1-磷酸的方法中葡聚糖和无机磷酸的定义与前述4中的相同。
待用于合成葡萄糖-1-磷酸方法中的物质的量已知,并可以由本领域技术人员适当选择。
在根据本发明合成葡萄糖-1-磷酸方法中首先制备反应溶液。例如,可通过向合适溶剂中加入α-葡聚糖磷酸化酶、葡聚糖和无机磷酸来制备反应溶液。作为替代方案,可通过混合分别含有α-葡聚糖磷酸化酶、葡聚糖或无机磷酸的溶液来制备反应溶液。作为替代方案,可通过将其它固体成分与含α-葡聚糖磷酸化酶、葡聚糖和无机磷酸中一些成分的溶液混合来制备反应溶液。如果必要,为调节pH的目的,可以向此反应溶液中加入任何缓冲剂,只要它不抑制酶反应即可。如果必要,可以向此反应溶液中加入脱支酶。
然后,如果必要,通过本领域已知的方法加热反应溶液以使之反应。只要得到本发明的效果,反应温度可以是任何温度。代表性的反应温度可以是约30℃到约75℃。优选的是,此反应步骤中的溶液温度应使得预定反应时间后此反应溶液中所含α-葡聚糖磷酸化酶活性保持反应前活性的约20%或更高,更优选约30%或更高。这种温度优选是约55℃到约75℃,更优选约60℃到约75℃,进一步优选约60℃到约70℃,特别优选约60℃到约65℃。

以此方式,生产含葡萄糖-1-磷酸的溶液。
(6.使用根据本发明酶的其它生产方法)
除了前述生产方法以外,本发明耐热化α-葡聚糖磷酸化酶可用于使用α-葡聚糖磷酸化酶的本领域已知的任何生产方法。在这些生产方法中使用本发明耐热化α-葡聚糖磷酸化酶可容易的由本领域技术人员实施。
(7.通过本发明生产方法获得的葡聚糖的用途)
通过本发明生产方法获得的葡聚糖可用于本领域已知的葡聚糖用途。葡聚糖中,尤其是不溶性直链淀粉中,预测具有与膳食纤维相同的功能,并预计可用于健康食品。另外,因为直链淀粉具有例如能在分子中包合碘或脂肪酸的特性,可以预计在药物、化妆品或卫生产品领域的用途。直链淀粉能用作生产具有与直链淀粉相同包合能力的环糊精和环状淀粉(cycloamylose)的原材料。另外,含直链淀粉的膜具有与通用塑料相当的抗张强度,因而是非常有前景的生物降解塑料的材料。以此方式,可以预计直链淀粉的很多用途。

用商品化测定试剂盒定量葡萄糖。用葡萄糖AR-II显色试剂(由Wako PureChemical Industries,Ltd.制造)测定葡萄糖。
(1.2定量果糖)
用商品化测定试剂盒定量果糖。用F-kit,D-glucose/D-fructose(Roche制造)测定果糖。
(1.3定量葡萄糖-1-磷酸)
用以下方法定量葡萄糖-1-磷酸。向300μl测定试剂(200mM Tris-HCl(pH7.0),3mM NAD P,15mM氯化镁,3mM EDTA,15μM葡萄糖-1,6-二磷酸,6μg/ml葡萄糖磷酸变位酶,6μg/ml葡萄糖-6-磷酸脱氢酶)中加入600μl含适当稀释葡萄糖-1-磷酸的溶液,搅拌,所得反应混合物在37℃反应30分钟。此后,用分光光度计测定340nm吸光度。相似的测定已知浓度的葡萄糖-1-磷酸钠盐的吸光度,以制作标准曲线。将由样品获得的吸光度值拟合到此标准曲线上,并由此确定样品中葡萄糖-1-磷酸浓度。通常,在1分钟内产生1μmol葡萄糖-1-磷酸的活性定义为1单位。在此定量方法中,只定量葡萄糖-1-磷酸,而不定量无机磷酸的量。
(1.4定量无机磷酸)
用以下方法获得磷酸根离子形式的无机磷酸。向含无机磷酸的溶液(200μl)中混合800μl钼试剂(15mM钼酸铵,100mM乙酸锌),随后加入200μl 568mM抗坏血酸(pH5.0),搅拌,所得反应混合物在37℃反应30分钟。此后,用分光光度计测定850nm吸光度。相似的测定已知浓度的无机磷酸的吸光度,以制作标准曲线。将由样品获得的吸光度值拟合到此标准曲线上,并由此确定样品中无机磷酸的测定值。在此定量方法中,定量无机磷酸的量,而不定量葡萄糖-1-磷酸的量。
(1.5由葡萄糖-1-磷酸产生葡聚糖产率的计算方法)
通过以下公式,从反应终止后溶液中无机磷酸和葡萄糖的量得到不用蔗糖磷酸化酶、用α-葡聚糖磷酸化酶和作为起始材料的葡萄糖-1-磷酸产生葡聚糖(如直链淀粉)的产率。
(葡聚糖产率(%))
=(用于葡聚糖合成的葡萄糖(mM))÷(初始葡萄糖-1-磷酸(mM))×100
={(反应产生的无机磷酸(mM))-(反应后葡萄糖(mM))}÷(初始葡萄糖-1-磷酸(mM))×100
(1.6由蔗糖产生葡聚糖产量的计算方法)
用以下公式,从反应终止后溶液中葡萄糖、果糖和葡萄糖-1-磷酸的量得到SP-GP方法中用无机磷酸作为起始物产生葡聚糖(如直链淀粉)的产量。
葡聚糖(mM葡萄糖当量)
=(果糖(mM)-(葡萄糖-1-磷酸(mM))-(葡萄糖(mM))
此公式基于以下原理。
在本发明生产方法中,首先可以发生根据以下方程式的反应(A)。
(A)蔗糖+无机磷酸→葡萄糖-1-磷酸+果糖
此反应由蔗糖磷酸化酶催化。在此反应中,蔗糖和无机磷酸反应生成等摩尔量的葡萄糖-1-磷酸和果糖。因为所得果糖不再与其它物质反应,通过测定果糖的摩尔量可知所生成葡萄糖-1-磷酸的摩尔量。
除了前述反应(A)以外,作为副反应,蔗糖磷酸化酶可以催化以下反应(B)中蔗糖水解。
(B)蔗糖→葡萄糖+果糖
掺入葡聚糖中的葡萄糖量可如下计算。
掺入葡聚糖中的葡萄糖量
=(反应(A)生成的葡萄糖-1-磷酸量)-(未反应葡萄糖-1-磷酸量)
=(反应(A)生成的果糖量)-(未反应葡萄糖-1-磷酸量)
考虑到反应(B)生成的果糖,如下计算反应(A)生成的果糖量:
反应(A)生成的果糖量
=(反应终止后的果糖量)-(反应终止后的葡萄糖量)
因此,由以下公式得到葡聚糖的产量。
(葡聚糖(mM葡萄糖当量))
=(果糖(mM)-(葡萄糖-1-磷酸(mM))-(葡萄糖(mM))
由以下公式,从起始葡萄糖-1-磷酸量以及反应终止后溶液中葡萄糖、果糖和葡萄糖-1-磷酸量得到用葡萄糖-1-磷酸作为起始材料生成的葡聚糖产量。
(葡聚糖(mM葡萄糖当量))
=(起始葡萄糖-1-磷酸(mM))+(果糖(mM)-(葡萄糖(mM))-(反应后葡萄糖-1-磷酸(mM))
此公式基于以下原理。
在反应溶液中,除了起始葡萄糖-1-磷酸,还由反应(A)产生葡萄糖-1-磷酸。也就是说,起始葡萄糖-1-磷酸和生成的葡萄糖-1-磷酸可用于葡聚糖合成。通过从可用于葡聚糖合成的葡萄糖-1-磷酸量中减去反应终止后反应溶液中剩余的葡萄糖-1-磷酸量,可以计算用于反应的葡萄糖-1-磷酸量,即掺入葡聚糖中的葡萄糖量。因此,可用前述公式得到掺入葡聚糖中的葡萄糖量。当在SP-GP反应体系中一起使用无机磷酸和葡萄糖-1-磷酸作为起始材料时也可应用此公式。
(1.7由蔗糖产生的葡聚糖产率的计算方法)
当用无机磷酸作为起始材料时生成的葡聚糖产率可用以下公式得到。
(葡聚糖产率(%))
=(葡聚糖(mM葡萄糖当量))/(起始蔗糖(mM))×100
当用葡萄糖-1-磷酸作为起始材料时生成的葡聚糖产率可用以下公式得到。
(葡聚糖产率(%))
={(起始葡萄糖-1-磷酸(mM))+(果糖(mM))-(葡萄糖(mM))-(反应后葡萄糖-1-磷酸(mM))}÷{(起始蔗糖(mM))+(起始葡萄糖-1-磷酸(mM))}×100
当在SP-GP反应体系中一起使用无机磷酸和葡萄糖-1-磷酸作为起始材料时此公式也适用。
(实施例1:马铃薯耐热化α-葡聚糖磷酸化酶的制备、筛选和测序)
简单概括的说,向马铃薯来源L型α-葡聚糖磷酸化酶基因中引入随机突变,将带有随机突变的基因导入大肠杆菌,表达带随机突变的α-葡聚糖磷酸化酶,并从表达α-葡聚糖磷酸化酶的大肠杆菌中,选择所表达的耐热化α-葡聚糖磷酸化酶在60℃加热10分钟后能够合成葡聚糖的大肠杆菌,从该大肠杆菌中分离耐热化α-葡聚糖磷酸化酶的基因,并确定其序列。
细节如下。
首先,制备马铃薯来源L型α-葡聚糖磷酸化酶(GP)基因。根据Takaha等人(Journal of Biological Chemistry,vol.268,pp.1391-1396,1993)所述,用公知方法从马铃薯块茎制备mRNA,并用商品试剂盒制备cDNA文库。
然后,基于已知GP基因序列(数据库GenBank登记号D00520),设计PCR引物1和PCR引物2。利用前述cDNA文库作模板,并用如下PCR引物1和2,PCR引物1:5′AAATCGATAGGAGGAAAACAT ATG ACC TTG AGT GAG AAA AT 3’(SEQ ID NO:38)
和
PCR引物2:5′GAAGGTACCTTTTCATTCACTTCCCCCTC3′(SEQ ID NO:39),进行PCR反应以扩增马铃薯来源GP的基因。PCR条件是30个循环的PCR反应,一个循环是94℃30秒、50℃1分钟和72℃3分钟。PCR引物1的下划线部分对应L型GP成熟蛋白N端区的结构基因序列,而PCR引物2的下划线部分对应L型GP结构基因终止密码子即下游的碱基序列。
扩增的GP基因插入预先用SmaI切割的质粒pMW118(由Nippon Gene Co.Ltd.制造)中,并选择具有如图2序列的质粒。用磷酸钙沉淀方法将此质粒导入大肠杆菌TG-1,选择氨苄青霉素抗性菌株,培养此氨苄青霉素抗性菌株,并从此氨苄青霉素抗性菌株回收质粒,从而得到马铃薯来源L型GP的基因。
用本领域技术人员已知的易错PCR方法(参考文献:Leung,et al.(Technique 1,11-15,1989)和Cadwell and Joyce(PCR Methods Applic.2,28-33,1992)),用PCR引物3和PCR引物4进行PCR反应,扩增所得马铃薯来源L型GP的基因,
PCR引物3:5′TTCGGATCCTCACCTTGAGTGAGAAAATTCAC-3′(SEQ ID NO:40)
和
PCR引物4:5′TTCGGATCCTTTTCATTCACTTCCCCCTC-3′(SEQ ID NO:41),PCR反应条件为90℃30秒,随后25个循环,一个循环是94℃30秒和68℃3分钟,随后68℃1分钟。所扩增DNA片段的平均2到3个位置引入碱基替换。PCR引物3的下划线部分对应L型GP成熟蛋白N端区的结构基因序列,而PCR引物4的下划线部分对应L型GP结构基因终止密码子即下游的碱基序列。
将带随机突变的GP基因扩增片段引入预先用BamHI切割的质粒pET3d(STRATAGENE制造)中,制备带随机突变的质粒文库供筛选耐热化GP。用此质粒转化大肠杆菌BL21(DE3),稀释转化子以获得独立菌落,并铺板于含氨苄青霉素的LB琼脂培养基(50μg/ml氨苄青霉素,Difco制造的胰蛋白胨1%,Difco制造的酵母提取物0.5%,NaCl 0.5%,1.5%琼脂糖,pH 7.3)上,随后在30℃培养24小时。将所得平板上的菌落转移到尼龙滤膜上。充分干燥粘附菌落的滤膜表面,并将滤膜在20mM柠檬酸盐缓冲液(pH6.7)中60℃保温10分钟。转移后,剩余平板接着在37℃培养数小时,然后保存于4℃作为母板。将热处理的滤膜施加到含葡聚糖合成底物的凝胶(含0.05%糊精,50mM G-1-P,100mM柠檬酸盐缓冲液(pH6.7),0.7%琼脂糖)上,使得粘附菌落的表面与凝胶表面粘附,并在50℃保温2小时。从凝胶上剥离滤膜,浸入碘溶液(0.1%碘化钾,0.01%碘)中,利用碘淀粉反应检测滤膜上合成的葡聚糖。从母板上分离对应染成蓝色的菌落。
从由此所得每种大肠杆菌中,根据本领域已知方法回收质粒,并用DNA测序仪(ABI制造)确定此质粒上耐热化α-葡聚糖磷酸化酶基因的碱基序列。
当将由这种耐热化α-葡聚糖磷酸化酶基因编码的氨基酸序列与天然马铃薯L型(即突变前)α-葡聚糖磷酸化酶的氨基酸序列进行比较时,突变被引入天然马铃薯L型α-葡聚糖磷酸化酶的第39位、第135位或第706位氨基酸,并分别发生氨基酸替换F39→L、N135→S或T706→I。此外,F39突变成非L氨基酸、N135突变成非S氨基酸或T706突变成非I氨基酸的GP中也发现耐热性提高。
(实施例2-1A:通过定点突变制备马铃薯L型耐热化α-葡聚糖磷酸化酶)
在本实施例中,制备只在实施例1中发现有助于提高耐热性的一个位置发生替换的耐热化GP、具有任意两个替换组合的耐热化GP、和具有所有三个替换的耐热化GP。作为实例,具有所有三种突变(F39L+N135S+T706I)的耐热化GP的氨基酸序列表示于SEQ ID NO:34,编码它的碱基序列表示于SEQ ID NO:33。为了比较,制备在第39位、第135位和第706位没有氨基酸替换、而在与这些氨基酸位置无关位置的氨基酸被替换(仅467位赖氨酸被替换成天冬氨酸的GP,和仅711位苏氨酸被替换成丙氨酸的GP)的GP。已公开很多替换氨基酸的方法(参考文献:Kinkel,T.A.,Proc.Natl.Acad.Sci.USA,82:488(1995),Vandeyar,M.,et al.,Gene,65:129-133(1988),Sugimoto,M.,et al.,Anal.Biochem.,179:309-311(1989),Taylor,J.W.and Eckstein,F.,Nucl.Acids Res.,13:8764(1985),Nelson,M.and McClelland,M.,Methods Enzymol.,216:279-303(1992))。
在本发明中,使用Quick change XL Site-Directed Mutagenesis试剂盒(STRATAGENE制造)。使用实施例1中所示的含插入pMW-118质粒中的马铃薯来源L型GP基因的质粒作为模板,并且每个突变使用一组引入突变的引物,进行PCR反应,以实现定点突变,其中每组引物相对于中心引入突变位置有约35bp互补,并设计引入突变F39L、N135S、T706I、K467D或T711A。制备含由此获得的耐热化GP编码基因的质粒pMW-PGP。用该质粒转化大肠杆菌TG-1,稀释转化子以获得独立菌落,并铺板到含氨苄青霉素的LB琼脂培养基(50μg/ml氨苄青霉素,Difco制造的胰蛋白胨1%,Difco制造的酵母提取物0.5%,NaCl 0.5%,1.5%琼脂糖,pH 7.3)上,随后在37℃培养过夜。在这种含氨苄青霉素的LB琼脂培养基上生长的大肠杆菌携带导入的质粒。以此方式,制备表达耐热化GP的大肠杆菌。从所得大肠杆菌中提取质粒,并测序编码GP的基因,确认本实施例获得的大肠杆菌中含有的质粒具有编码带目标突变的耐热化GP的突变型GP基因。
按如下验证本实施例所得大肠杆菌表达的GP是耐热化GP。携带导入质粒的大肠杆菌TG-1接种在含氨苄青霉素的LB琼脂培养基(50μg/ml氨苄青霉素,Difco制造的胰蛋白胨1%,Difco制造的酵母提取物0.5%,NaCl 0.5%,1.5%琼脂糖,pH7.3)上,随后在37℃生长到对数中期,温度降低到约22℃,加入基因表达诱导剂异丙基β-D-硫代半乳糖苷到终浓度0.1mM,加入吡哆醇到终浓度1mM,随后在22℃培养约20小时。离心培养物以回收细菌细胞,将细菌细胞悬于缓冲液中,并超声处理悬液以得到细菌细胞提取物。将此细菌提取物在60℃处理30分钟,以获得确证的GP制备物。
当通过使蔗糖磷酸化酶和α-葡聚糖磷酸化酶对蔗糖和引发剂进行反应的方法(描述于国际公开WO 02/097107小册子中的方法),用所得确证GP制备物生产葡聚糖时,对于所有耐热化α-葡聚糖磷酸化酶可以高产率获得高分子量葡聚糖。
另一方面,在与提高耐热性无关位置氨基酸被替换的GP经60℃处理30分钟被灭活,而不能产生葡聚糖。
(实施例2-1B:制备多种氨基酸替换的修饰型马铃薯L型α-葡聚糖磷酸化酶)
除了使用设计的引物使得在F39、N135和T706的一个位置用另一个氨基酸残基替换以外,根据与实施例2-1A相同的方式,制备含修饰型α-葡聚糖磷酸化酶基因的质粒,并得到多种修饰型GP的确证制备物。
这些修饰型GP确证制备物的耐热性在以下实施例3-1(3-1)中详细研究。
(实施例2-2A:通过定点突变制备马铃薯H型耐热化α-葡聚糖磷酸化酶)
除了用马铃薯来源H型α-葡聚糖磷酸化酶基因代替马铃薯来源L型α-葡聚糖磷酸化酶基因以外,根据与实施例2-1A相同的方式,制备含耐热化α-葡聚糖磷酸化酶基因的质粒,并获得GP的确证制备物。在本实施例中,制备下述耐热化GP,在实施例1中发现有助于提高耐热性的替换位置中,其仅在对应马铃薯L型α-葡聚糖磷酸化酶氨基酸序列中N135S或T706I的位置(分别是马铃薯H型α-葡聚糖磷酸化酶氨基酸序列的第133位和第628位)具有一个替换。
当如实施例2-1A所述将这些GP确证制备物用于60℃处理30分钟并制备葡聚糖时,所有耐热化α-葡聚糖磷酸化酶都可获得高分子量葡聚糖,这与天然马铃薯H型α-葡聚糖磷酸化酶相似。
(实施例2-2B:用定点突变制备马铃薯H型耐热化α-葡聚糖磷酸化酶)
除了用马铃薯来源H型α-葡聚糖磷酸化酶基因代替马铃薯来源L型α-葡聚糖磷酸化酶基因、并使用引入突变的引物使得在对应F39的位置(Y36)、对应N135的位置(N133)和对应T706的位置(T628)分别用亮氨酸(L)、丝氨酸(S)和异亮氨酸(I)替换以外,根据与实施例2-1A相同的方式,制备含耐热化α-葡聚糖磷酸化酶基因的质粒,并获得三重突变型(Y36L+N133S+T628I)GP的确证制备物。在本实施例中,制备在实施例1中发现有助于提高耐热性的所有三个位置进行替换的耐热化GP。

首先,用商品化拟南芥来源的cDNA(PCR Ready First Strand cDNA,Wako PureChemical Industries,Ltd.制造)制备拟南芥来源的H型α-葡聚糖磷酸化酶基因。
更具体的,基于已知拟南芥GP基因序列(数据库GenBank登记号AL133292;CAB61943.1),设计PCR引物5和6。用前述拟南芥来源的cDNA作模板,并用:
PCR引物5:5’AAATCGATAGGAGGAAAACAT ATG GCA AAC GCC AAT GGA AAA GCT GCG ACT AGT TTA CCG GAG AAA ATC TC 3′(SEQ ID NO:42)
和
PCR引物6:5′GAAGGTACC TTA GGG AAC AGG ACA AGC CTC AAT GTT CCA AAT CTC TTT GGC ATA CTG AG 3′(SEQ ID NO:43),进行PCR,以扩增拟南芥来源的H型GP基因。PCR反应条件是30个循环,一个循环是94℃30秒、60℃1分钟和72℃3分钟。PCR引物5的下划线部分对应拟南芥来源H型GP基因成熟蛋白N端区的结构基因,而PCR引物6的下划线部分对应拟南芥来源H型GP基因成熟蛋白C端区的结构基因。
将扩增的拟南芥来源H型GP基因插入预先用SmaI切割的pMW118质粒(由Nippon Gene Co.,Ltd.制造),用感受态细胞方法将质粒导入大肠杆菌TG-1,选择氨苄青霉素抗性菌株,培养此氨苄青霉素抗性菌株,并从此氨苄青霉素抗性菌株中回收质粒,从而获得拟南芥来源的H型GP基因。
除了用所得拟南芥来源的H型GP基因代替马铃薯来源的L型GP基因、并使用引入突变的引物使得在对应F39的位置(Y40)、对应N135的位置(N136)和对应T706的位置(N631)分别用亮氨酸(L)、丝氨酸(S)和异亮氨酸(I)替换以外,根据与实施例2-1A相同的方式,制备含耐热化α-葡聚糖磷酸化酶基因的质粒,并获得三重突变型(Y40L+N136S+N631I)GP的确证制备物。在本实施例中,制备在实施例1中发现有助于提高耐热性的所有三个位置进行替换的耐热化GP。
这些修饰型GP的确证制备物的耐热性在以下实施例3-2(2)中详细研究。
(实施例3-1:大规模制备多种耐热化α-葡聚糖磷酸化酶并比较耐热性)
(1)大规模制备酶
实施例2-1A或2-1B中制备的表达耐热化GP的各种大肠杆菌在TB培养基(含Terrific broth(GIBCO)47g/L,甘油4ml/L和50μg/ml氨苄青霉素)中37℃培养5小时。向此培养液中加入IPTG和盐酸吡哆醇至终浓度0.1mM IPTG和1mM盐酸吡哆醇,继续在22℃培养24小时。然后离心培养物回收细菌细胞,用20mM柠檬酸盐缓冲液(pH6.7)洗涤除去培养基成分。洗涤后细菌细胞悬于20mM柠檬酸盐缓冲液(pH6.7),用超声仪裂解细菌细胞,离心,取上清液用作细菌细胞提取物。所得细菌细胞提取物加载到预平衡的Q-Sepharose FF柱上,回收用含0.1M到0.3M NaCl浓度梯度的20mM柠檬酸盐缓冲液(pH6.7)洗脱的含耐热化GP的组分。所回收酶组分加载到预平衡的Phenyl-TOYOPEARL 650M柱上,并回收用含17.5%到7.5%饱和度的硫酸铵浓度梯度的20mM柠檬酸盐缓冲液洗脱的含耐热化GP组分的组分。所回收酶组分加载到预平衡的HiTrap HQP柱,并回收用含0.1M到0.4M NaCl浓度梯度的20mM柠檬酸盐缓冲液洗脱的活性组分。所得活性组分进一步加载到预平衡的Resource Q柱上,用含0.1M到0.4M NaCl浓度梯度的20mM柠檬酸盐缓冲液洗脱,以回收含纯化酶的活性组分。
取约1μg所得含纯化酶活性组分进行非变性PAGE(Native聚丙烯酰胺凝胶电泳)。结果,对于所有表达耐热化GP的大肠杆菌,在分子量约210kDa处见到单一条带,并且在任意其它位置未发现条带。因为从氨基酸序列预测GP的分子量为约104kDa,认为GP具有二聚体结构。这样就表明耐热化GP得到了均质纯化。
(2)测定纯化的耐热化GP的活性
测定(1)中纯化的耐热化GP的活性。按如下测定。首先,200μl反应液(含12.5mM G-1-P、1%糊精和酶溶液的100mM乙酸盐缓冲液(pH6.0))在37℃保温15分钟。然后,加入800μl钼试剂(15mM钼酸铵,100mM乙酸锌),并搅拌以终止反应。然后,加入200μl 568mM抗坏血酸(pH5.8),混合,并在37℃保温15分钟,用分光光度计测定850nm吸光度。在本实施例中,通过定量由G-1P生成的游离无机磷酸来测定GP酶活性。1分钟内生成1μmol无机磷酸的酶量被定义为1个单位(U)。

在上表5和表6中,天然马铃薯L型指天然马铃薯来源的L型α-葡聚糖磷酸化酶。F39L指第39位苯丙氨酸替换成亮氨酸的天然马铃薯来源L型α-葡聚糖磷酸化酶。T706I指第706位苏氨酸替换成异亮氨酸的天然马铃薯来源L型α-葡聚糖磷酸化酶。N135S指第135位天冬酰胺替换成丝氨酸的天然马铃薯来源L型α-葡聚糖磷酸化酶。F39L+T706I指第39位苯丙氨酸替换成亮氨酸并且第706位苏氨酸替换成异亮氨酸的天然马铃薯来源L型α-葡聚糖磷酸化酶。N135S+T706I指第135位天冬酰胺替换成丝氨酸并且第706位苏氨酸替换成异亮氨酸的天然马铃薯来源L型α-葡聚糖磷酸化酶。F39L+N135S指第39位苯丙氨酸替换成亮氨酸并且第135位天冬酰胺替换成丝氨酸的天然马铃薯来源L型α-葡聚糖磷酸化酶。F39L+N135S+T706I指第39位苯丙氨酸替换成亮氨酸、第135位天冬酰胺替换成丝氨酸并且第706位苏氨酸替换成异亮氨酸的天然马铃薯来源L型α-葡聚糖磷酸化酶。在表5和表6给出的结果中,60℃加热30分钟的结果和65℃加热2分钟的结果作为图示于图3。
发现:与天然马铃薯L型GP比较,本发明耐热化GP具有非常高的耐热性。从耐热性较差GP到耐热性极佳GP的顺序如下:天然马铃薯L型GP<F39L<T706I<N135S<F39L+T706I<N135S+T706I<F39L+N135S<F39L+N135S+T706I。通过在有助于耐热性的三个位置氨基酸残基中仅替换一个位置提高了耐热性。进而,可以看到,通过替换多个这些氨基酸残基,耐热性急剧提高。
(3-2)比较实施例2-1B制备的修饰型GP在60℃和65℃的耐热性
比较实施例2-1B制备并在实施例3-1(1)中大规模制备和纯化的各种修饰型GP在60℃和65℃的耐热性。使用通过相同方法纯化的天然(非突变)马铃薯L型α-葡聚糖磷酸化酶作为对照。
首先,0.2U/ml纯化酶溶液(在20mM柠檬酸盐缓冲液(pH6.7)中)在60℃保温10分钟或65℃保温2分钟。在预定时间点(10分钟或2分钟)取酶溶液的小份,并保持于冰上。用20mM柠檬酸盐缓冲液(pH6.7)将保持于冰上的酶溶液样品稀释10倍,并根据(2)中描述的活性测定方法测定酶活性。将60℃保温10分钟或65℃保温2分钟前的酶在37℃的酶活性当作100%,用保温后酶在37℃的酶活性比率(即剩余活性)判断酶的耐热性。结果表示于下表7和图8-10中。
表7
在上表7中,WT指天然马铃薯来源的L型α-葡聚糖磷酸化酶。每一行中,单字母缩写代表的氨基酸表示修饰型GP中的氨基酸替换。例如左端有记F39的行中用I表达的实体是指第39位苯丙氨酸替换成异亮氨酸的修饰型GP。对于其它行中的修饰型GP也是如此。
氨基酸的单字母缩写对本领域技术人员公知,并如下列出:A,丙氨酸;C,半胱氨酸;D,天冬氨酸;E,谷氨酸;F,苯丙氨酸;G,甘氨酸;H,组氨酸;I,异亮氨酸;K,赖氨酸;L,亮氨酸;M,甲硫氨酸;N,天冬酰胺;P,脯氨酸;Q,谷氨酰胺;R,精氨酸;S,丝氨酸;T,苏氨酸;V,缬氨酸;W,色氨酸;Y,酪氨酸。
结果可以看出,当上述实施例2-1A中替换的特定氨基酸以外的氨基酸用来替换第39位、第135位和第706位氨基酸时,天然马铃薯来源L型GP的耐热性提高。
当第39位苯丙氨酸替换成异亮氨酸、亮氨酸或缬氨酸时,从60℃保温10分钟后的剩余活性来看,修饰型GP的耐热性高于天然马铃薯来源L型GP的耐热性。对于第39位的替换,替换成亮氨酸(60℃保温10分钟后的剩余活性是61.2%)对耐热性最佳。当第135位天冬酰胺替换成丙氨酸、半胱氨酸、天冬氨酸、谷氨酸、甘氨酸、组氨酸、异亮氨酸、亮氨酸、甲硫氨酸、苯丙氨酸、丝氨酸、苏氨酸、缬氨酸或酪氨酸时,修饰型GP的耐热性高于天然马铃薯来源L型GP的耐热性。对于第135位的替换,替换成丙氨酸(60℃保温10分钟后的剩余活性是76.2%)、半胱氨酸(60℃保温10分钟后的剩余活性是85.0%)、甘氨酸(60℃保温10分钟后的剩余活性是85.2%)、异亮氨酸(60℃保温10分钟后的剩余活性是60.0%)、丝氨酸(60℃保温10分钟后的剩余活性是65.4%)、苏氨酸(60℃保温10分钟后的剩余活性是73.4%)或缬氨酸(60℃保温10分钟后的剩余活性是82.8%)对耐热性特别好。当第706位苏氨酸替换成半胱氨酸、异亮氨酸、亮氨酸、缬氨酸或色氨酸时,修饰型GP的耐热性高于天然马铃薯来源L型GP的耐热性。对于第706位的替换,替换成半胱氨酸(60℃保温10分钟后的剩余活性是65.4%)、异亮氨酸(60℃保温10分钟后的剩余活性是70.5%)或缬氨酸(60℃保温10分钟后的剩余活性是68.7%)对耐热性特别好。
当第39位苯丙氨酸替换成异亮氨酸、亮氨酸或缬氨酸时,从65℃保温2分钟后的剩余活性来看,修饰型GP的耐热性高于天然马铃薯来源L型GP的耐热性。对于第39位的替换,替换成亮氨酸(65℃保温2分钟后的剩余活性是61.2%)对耐热性最佳。当第135位天冬酰胺替换成丙氨酸、半胱氨酸、天冬氨酸、谷氨酸、甘氨酸、组氨酸、异亮氨酸、亮氨酸、甲硫氨酸、苯丙氨酸、丝氨酸、苏氨酸、缬氨酸或酪氨酸时,修饰型GP的耐热性高于天然马铃薯来源L型GP的耐热性。对于第135位的替换,替换成丙氨酸(65℃保温2分钟后的剩余活性是79.0%)、半胱氨酸(65℃保温2分钟后的剩余活性是76.9%)、甘氨酸(65℃保温2分钟后的剩余活性是58.4%)、甲硫氨酸(65℃保温2分钟后的剩余活性是52.6%)、丝氨酸(65℃保温2分钟后的剩余活性是86.5%)、苏氨酸(65℃保温2分钟后的剩余活性是62.4%)或缬氨酸(65℃保温2分钟后的剩余活性是79.3%)对耐热性特别好。当第706位苏氨酸替换成半胱氨酸、异亮氨酸、亮氨酸、缬氨酸或色氨酸时,修饰型GP的耐热性高于天然马铃薯来源L型GP的耐热性。对于第706位的替换,替换成亮氨酸(65℃保温2分钟后的剩余活性是57.8%)或缬氨酸(65℃保温2分钟后的剩余活性是59.2%)对耐热性特别好。
结果发现,与天然马铃薯L型GP比较,本发明修饰型GP的耐热性有很大提高。
(实施例3-2:制备H型耐热化GP酶)
(1)大规模制备酶
实施例2-2B和2-2C中制备的表达马铃薯H型耐热化GP的每种大肠杆菌和表达拟南芥H型耐热化GP的每种大肠杆菌分别在TB培养基(含Terrific broth(GIBCO)47g/L,甘油4ml/L和50μg/ml氨苄青霉素)中37℃培养5小时,向此培养液中加入IPTG和盐酸吡哆醇至终浓度0.1mM IPTG和1mM盐酸吡哆醇,继续在22℃培养24小时。然后离心培养物回收细菌细胞,用20mM柠檬酸盐缓冲液(pH6.7)洗涤除去培养基成分。洗涤后细菌细胞悬于20mM柠檬酸盐缓冲液(pH6.7),用超声仪裂解细菌细胞,离心,取上清液用作细菌细胞提取物。所得细菌细胞提取物用离子交换层析和疏水层析纯化,以回收含纯化酶的活性组分,所述组分在非变性PAGE(Native聚丙烯酰胺凝胶电泳)中显示为单一条带。
(2)比较耐热化H型GP酶的耐热性
比较(1)中纯化的各种耐热化GP在60℃和65℃的耐热性。使用通过相同方法纯化的天然(非突变)马铃薯H型GP和拟南芥H型GP作为对照。
0.2U/ml纯化酶溶液(20mM柠檬酸盐缓冲液(pH6.7))在60℃保温10分钟或65℃保温2分钟,并保持于冰上。用20mM柠檬酸盐缓冲液(pH6.7)将保持于冰上的酶溶液稀释10倍,并根据实施例3-1(2)中描述的活性测定方法测定酶活性。将58℃保温10分钟、60℃保温10分钟或65℃保温2分钟前的酶在37℃的酶活性当作100%,用保温后酶在37℃的酶活性比率(即剩余活性)判断酶的耐热性。耐热化马铃薯H型GP和天然马铃薯H型GP的结果示于下表8和图11。耐热化拟南芥H型GP和天然拟南芥H型GP的结果示于下表9和图12。
表8
保温温度和时间 | 天然马铃薯H型GP的剩余活性(%) | 耐热化马铃薯H型GP的剩余活性(%)(Y36L+N133S+T628I) |
58℃10分钟 | 0 | 75.8 |
60℃10分钟 | 0 | 48.8 |
65℃2分钟 | 0 | 34.5 |
表9
保温温度和时间 | 天然拟南芥H型GP的剩余活性(%) | 耐热化拟南芥H型GP的剩余活性(%)(Y40L+N136S+T631I) |
58℃10分钟 | 1.5 | 48.8 |
60℃10分钟 | 0.5 | 29.3 |
65℃2分钟 | 0.5 | 29.2 |
从这些结果来看,甚至在65℃加热2分钟以后,本发明的耐热化马铃薯H型GP仍保留34.5%活性。另一方面,65℃加热2分钟以后天然马铃薯H型GP保留0%活性。由此发现,与天然马铃薯H型GP比较,本发明的耐热化马铃薯H型GP具有高度耐热性。
此外,甚至在65℃加热2分钟以后,本发明的耐热化拟南芥H型GP仍保留29.2%活性。另一方面,65℃加热2分钟以后天然拟南芥H型GP保留0.5%活性。由此发现,与天然拟南芥H型GP比较,本发明的耐热化拟南芥H型GP具有高度耐热性。
(实施例4:用耐热化α-葡聚糖磷酸化酶合成重均分子量600kDa或更高的直链淀粉)
使用根据本发明的耐热化α-葡聚糖磷酸化酶,研究是否可以合成重均分子量600kDa或更高的直链淀粉。使用以上实施例3-1(1)制备的多种耐热化GP的任何一种(单突变F39L、单突变N135S、单突变T706I、双突变(F39L+N135S)、双突变(F39L+T706I)、双突变(N135S+T706I)和三突变(F39L+N135S+T706I))作为耐热化α-葡聚糖磷酸化酶。
使用嗜热脂肪芽孢杆菌来源的α-葡聚糖磷酸化酶(也称作嗜热脂肪芽孢杆菌)和水生栖热菌来源的α-葡聚糖磷酸化酶(也称作水生栖热菌)作为对照。
使用具有下表10所述组成的反应溶液在50℃进行直链淀粉合成反应18小时。
表10
使用描述于前述“1.测定方法和计算方法”的1.5中的计算方法计算该反应合成的直链淀粉产率。
用以下方法测定该反应合成直链淀粉的重均分子量。该反应合成的直链淀粉完全溶解于1N氢氧化钠中,用适量盐酸中和,取约30-300μg等份直链淀粉用于同时使用差示折光计和多角光散射检测器的凝胶过滤层析,以获得重均分子量。
更具体的,使用Shodex SB806M-HQ(SHOWA DENKO K.K.制造)作为柱子,使用多角光散射检测器(DAWN-DSP,Wyatt Technology制造)作为检测器,并通过以这种顺序将它们连接而使用差示折光计(Shodex RI-71,SHOWA DENKO K.K.制造)。柱子保持在40℃,并使用0.1M硝酸钠溶液以1mL/min流速作为洗脱剂。用数据分析软件(商品名ASTRA,Wyatt Technology制造)收集所得信号,并用相同软件分析,从而得到重均分子量。这种方法也称为MALLS分析法。
以此方式获得的合成直链淀粉的产率和分子量示于下表11。
表11
合成直链淀粉的产率和分子量
如上所述,发现本发明的耐热化GP可以合成重均分子量约600kDa或更高的高分子直链淀粉。此外,还发现本发明的耐热化GP合成直链淀粉的产率约40%或更高。用作比较实施例的嗜热脂肪芽孢杆菌GP和水生栖热菌GP是耐热性酶,但不能合成高分子直链淀粉。
(实施例5:用耐热化α-葡聚糖磷酸化酶从蔗糖合成直链淀粉)
使用根据本发明的耐热化α-葡聚糖磷酸化酶,并使用蔗糖作为原材料,来合成直链淀粉。使用以上实施例3-1(1)制备的所述多种耐热化GP的任何一种(单突变F39L、单突变N135S、单突变T706I、双突变(F39L+N135S)、双突变(F39L+T706I)、双突变(N135S+T706I)和三突变(F39L+N135S+T706I))作为耐热化α-葡聚糖磷酸化酶。
使用具有下表12所述组成的反应溶液在50℃进行直链淀粉合成反应18小时。
表12
使用描述于前述“1.测定方法和计算方法”的1.7中的计算公式计算该反应合成的直链淀粉产率(%)。
用与以上实施例4中相同的方法测定该反应合成直链淀粉的重均分子量。以此方式获得的合成直链淀粉的产率和分子量示于下表13。
表13
合成直链淀粉的产率和重均分子量
如上所述,发现当用蔗糖作为合成直链淀粉的原材料时,像天然GP一样,本发明的耐热化GP可以合成重均分子量约600kDa的高分子直链淀粉。此外,还发现与天然GP相似,直链淀粉的产率高,如约40%或更高。
(实施例6:在高温条件下(50℃、55℃和60℃)用耐热化GP由葡萄糖-1-磷酸合成葡聚糖)
使用根据本发明的耐热化α-葡聚糖磷酸化酶,并使用葡萄糖-1-磷酸作为原材料,在高温条件下来合成直链淀粉。使用实施例3-1(1)制备的耐热化GP(三突变(F39L+N135S+T706I)),同时使用由相同方法纯化的天然马铃薯L型GP作为对照。
通过在37℃、50℃、55℃或60℃将含G-1-P 6.1g/L、麦芽四糖(G4)0.3g/L和GP 20U/L的反应溶液保温18小时进行直链淀粉合成反应。时间过去后测定反应产物中的合成直链淀粉的量。基于以下公式计算合成直链淀粉的量(g/L)。
(合成直链淀粉的量(g/L))
=(用于直链淀粉合成的葡萄糖(mM))×180(葡萄糖分子量)
=[(反应生成的无机磷酸(mM))-(反应后葡萄糖(mM))]×180(葡萄糖分子量)
反应18小时后合成直链淀粉的量示于下表14和图17。
表14
合成直链淀粉的量(g/L)
反应温度 | 天然马铃薯L型GP | 耐热化GP |
37℃ | 2.8 | 3.1 |
50℃ | 3.2 | 3.3 |
55℃ | 2.5 | 2.7 |
60℃ | 0 | 1.5 |
当使用耐热化GP时,在37℃、50℃和55℃合成约3g/L直链淀粉,甚至在60℃也合成约1.5g/L直链淀粉。另一方面,当使用天然马铃薯L型GP时,在37℃、50℃和55℃有直链淀粉合成,但在60℃根本不合成直链淀粉。认为对于天然马铃薯L型GP,60℃时在反应的起始阶段GP即被灭活。另一方面,认为因为耐热化GP在60℃也稳定保留酶活性,足以使直链淀粉合成反应进行。此外,当在37℃、50℃、55℃和60℃的每个温度使用耐热化GP时,所合成直链淀粉量大于使用天然马铃薯L型GP时的量。可以认为,使用耐热化GP合成直链淀粉的量将随着反应时间延长进一步增加。如上所述,发现根据本发明的耐热化GP可以在60℃合成葡聚糖,而天然马铃薯L型GP不能在此温度反应。
(实施例7:用耐热化GP在65℃和70℃由葡萄糖-1-磷酸合成葡聚糖)
如实施例6,使用实施例3-1(1)制备的耐热化GP(三突变(F39L+N135S+T706I)),在更高温度条件下由葡萄糖-1-磷酸合成葡聚糖。使用天然马铃薯L型GP作为对照。
通过在37℃、65℃或70℃将含G-1-P 15.2g/L、麦芽四糖(G4)2.7g/L和GP 200U/L的反应溶液保温4小时进行直链淀粉合成反应。如实施例6计算合成直链淀粉的量。反应4小时后,当使用马铃薯L型GP时,在65℃或70℃根本不合成直链淀粉,而当使用耐热化GP时,在65℃由15.2g G-1-P合成约5.6g/L直链淀粉,而在70℃由15.2g G-1-P合成约0.3g/L直链淀粉。结果发现,天然马铃薯L型GP不能在65℃到70℃合成直链淀粉,但耐热化GP在高温如70℃保持GP活性,并具有合成直链淀粉能力。
基于实施例6和7的结果,发现根据本发明的耐热化GP在高温条件下具有合成直链淀粉的能力,而天然马铃薯L型GP在如此条件下根本不反应。
(实施例8:确认经热处理去除污染蛋白质)
确认:使用热处理,以下方法可用于容易地纯化耐热化α-葡聚糖磷酸化酶。
如实施例2-1A所述,将实施例2-1A中制备的表达耐热化GP(三重突变体(F39L+N135S+T706I))基因的大肠杆菌(TG-1)培养于LB培养基中。如实施例2-1A所述,将表达天然马铃薯L型α-葡聚糖磷酸化酶的大肠杆菌(TG-1)培养于LB培养基中作为对照。离心培养液回收细菌细胞,细菌细胞悬于缓冲液中,并进行超声以获得细菌细胞提取物。在60℃水浴中加热该细菌细胞提取物0到60分钟,离心去除不溶性蛋白以获得上清液。测定该上清液的GP活性和蛋白质含量,从而得到GP酶的比活性。用实施例3-1(2)所述活性测定方法测定GP活性,用Bradford方法(Bradford,M.,Anal.Biochem.,72,248-254(1976))测定蛋白质含量。Bradford方法是一种比色方法,其中显色物质与溶液中含有的所有蛋白质结合。在本说明书中,用蛋白质测定试剂盒(Nippon Bio-Rad Laboratories,Inc.)和牛球蛋白作为标准品进行测定。
由以下方法计算GP酶比活性。
比活性(U/ml)
=(α-葡聚糖磷酸化酶活性)/(上清液中所含蛋白质的质量mg)
图6表示耐热化GP酶(称作耐热化GP(F39L+N135S+T706I))和天然马铃薯L型GP酶比活性随时间的变化。
如图6所示,耐热化GP的比活性经60℃加热增加约10倍。污染蛋白几乎完全热变性并被除去。相反,天然马铃薯L型GP的比活性随时间降低。可以认为这是因为不仅污染蛋白而且所述GP蛋白也被变性。以此方式,发现经热处理可以简单的纯化耐热化GP。
(实施例9:确认经热处理去除污染蛋白质)
如实施例8,培养表达耐热化GP(F39L+N135S+T706I)基因的大肠杆菌(TG-1),并制备细菌细胞提取物。使用该细菌细胞提取物,确认经过60℃热处理可以使淀粉酶活性和磷酸酶活性降低到可用于工业生产直链淀粉或G-1-P的水平。
如实施例8,在60℃水浴中加热细菌细胞提取物30分钟,离心去除不溶性蛋白以获得上清液。测定该上清液的磷酸酶活性和淀粉酶活性。
通过将含100μl该上清液和100μl 50mM葡萄糖-1-磷酸的反应溶液在37℃保温60分钟,并用(1.测定方法和计算方法)所述的方法定量由反应溶液中葡萄糖-1-磷酸生成的游离无机磷酸,从而测定磷酸酶活性。在1分钟内生成1μmol无机磷酸的酶量定义为1个单位(U)。通过将含25μl该上清液和25μl 0.5%直链淀粉(重均分子量约50kDa)的反应溶液在37℃保温60分钟,加入1ml碘溶液(0.1%碘化钾,0.01),并测定伴随反应溶液中直链淀粉转化成低分子直链淀粉时碘显色的降低速率,获得酶活性。在1分钟内能降低A660吸光度约10%的活性定义为1U。
淀粉酶活性(U/分钟)
=(反应前A660nm吸光度-反应后A660nm吸光度)÷(反应前A660nm吸光度)×100÷10÷(时间(分钟))
下表15表示细菌细胞提取物中磷酸酶活性和淀粉酶活性的剩余比例。
如表15所示,将加热前细菌细胞提取物的活性当作100%,经60℃加热后,磷酸酶活性和淀粉酶活性分别是磷酸酶活性约3%,淀粉酶活性约0.3%,这两种污染蛋白质几乎被灭活。
表15
磷酸酶活性(%) | 淀粉酶活性(%) | |
加热前 | 100 | 100 |
60℃加热30分钟后 | 3.1 | 0.3 |
以此方式,根据本发明的耐热化α-葡聚糖磷酸化酶是即使经60℃热处理也不丧失活性的植物GP酶,并发现,经过60℃热处理可以容易的生产含很少淀粉酶活性和磷酸酶活性的极好GP。
(实施例10:GP蛋白质的稳定性)
已经报道天然马铃薯来源L型GP容易降解。这些GP,甚至纯化后低温保存,在保存期间也逐渐降解。一般来说,酶降解时,结构发生变化,酶的性质发生变化,同时活性降低等。如果能增强GP蛋白质稳定性,则可以降低以上因素的影响,这有利于酶的保存和使用。
将实施例3-1(1)制备的天然马铃薯来源L型GP和7种耐热化GP(单突变F39L、单突变N135S、单突变T706I、双突变(F39L+N135S)、双突变(F39L+T706I)、双突变(N135S+T706I)和三突变(F39L+N135S+T706I))保存于4℃,并经过5个月检测所述GP蛋白质的分子量。此外,相似的检测37℃保存10天后的GP蛋白质分子量。纯化后即刻和4℃保存5个月后,用聚丙烯酰胺凝胶电泳检测分子量,结果示于图13。加到凝胶上的蛋白量对所有GP蛋白相同。
结果,纯化后即刻,天然马铃薯L型GP和7种耐热化GP都在分子量约210kDa位置(GP单体分子量约104kDa,形成二聚体)显示条带。另一方面,天然马铃薯L型GP和N135S突变体在4℃保存5个月后具有约140kDa的分子量,这比纯化后即刻要小。这表明在保存期间天然马铃薯L型GP和N135S单突变体被降解。天然马铃薯L型GP和N135S突变体在37℃保存10天后也被降解。另外6种耐热化GP(单突变F39L、单突变T706I、双突变F39L+N135S、双突变F39L+T706I、双突变N135S+T706I和三突变F39L+N135S+T706I)在4℃保存5个月后的分子量约为210kDa,这与纯化后即刻相同,未发现蛋白质降解。此外,这六种耐热化GP在37℃保存10天后分子量也没有改变,未发现这些GP蛋白降解。这表明这些耐热化GP在4℃到37℃具有出色的抗降解能力,并且比天然马铃薯L型GP具有更高稳定性。由此发现,F39位替换和T706位替换不仅提供提高耐热性的作用,而且提供抑制GP蛋白质降解的作用。
(实施例11:合成葡萄糖-1-磷酸)
(1)用耐热化GP在65℃合成G-1-P
使用根据本发明的耐热化α-葡聚糖磷酸化酶,并使用葡聚糖和无机磷酸作为原材料,在65℃合成葡萄糖-1-磷酸。使用实施例3-1(1)中制备的耐热化GP(三突变(F39L+N135S+T706I)),并使用由同样方法纯化的天然马铃薯L型GP作为对照。通过在37℃或65℃将反应溶液保温18小时,进行G-1-P合成反应,其中所述反应溶液含300mM磷酸盐缓冲液(pH7.0)、10g/L糊精和1000U/L任一种GP。用以上“1.测定方法和计算方法”的1.3中所述的定量葡萄糖-1-磷酸方法获得的G-1-P浓度(mM)乘以G-1-P的分子量260,计算合成G-1-P的量。反应后合成G-1-P的量示于下表16。
表16
合成葡萄糖-1-磷酸的量(g/L)
反应温度 | 天然马铃薯L型GP | 耐热化GP |
37℃ | 3.5 | 4.2 |
65℃ | 0.0 | 3.7 |
当使用天然马铃薯L型GP时在65℃不合成G-1-P。然而当使用耐热化GP时,即使在65℃也可以生成G-1-P。
(2)用耐热化GP在70℃合成G-1-P
如以上实施例11(1),使用根据本发明的耐热化GP和天然马铃薯L型GP,并使用葡聚糖和无机磷酸作为原材料,在70℃合成G-1-P。将含300mM磷酸盐缓冲液(pH7.0)、10g/L糊精和10,000U/L任一种GP的反应溶液在70℃保温4小时,合成G-1-P。如前述实施例计算合成G-1-P的量。
当使用天然马铃薯L型GP时在70℃根本不合成G-1-P。然而当使用耐热化GP时,合成约1g G-1-P。
如上述,本发明用本发明的优选实施方案举例说明,但不应理解为将本发明限制到这些实施方案内。可以理解,本发明的范围只由权利要求书解释。可以理解,基于本发明的描述和常规技术知识,从本发明优选实施方案的具体描述,本领域技术人员可在等价的范围实施。可以理解,专利、专利申请和本说明书引用的参考文献内容本身应引入作为参考,就像其内容在本说明书中具体描述一样。
工业实用性
根据本发明得到在高温下(如60℃或更高)具有极佳耐热性的植物来源GP酶。本发明的耐热化α-葡聚糖磷酸化酶可用于高温条件(如60℃或更高)下的葡聚糖合成反应,天然GP酶在此条件下不能反应。
当使用中温性细菌如大肠杆菌作为宿主,高度表达根据本发明的编码耐热化α-葡聚糖磷酸化酶基因(如通过提高马铃薯来源GP耐热性获得的编码耐热化GP的基因)时,通过在60℃加热含耐热化酶的细菌细胞提取物,可以简单的除去来源于宿主细菌的污染酶。具体来说,淀粉酶活性和磷酸酶活性是大问题,尤其是在GP酶的工业应用中如此,经热处理可以大大降低这两种酶活性。因此,本发明的酶尤其在酶纯化中有用。
本发明方法不仅对马铃薯来源GP和拟南芥来源GP有效,而且可优选应用于提高与马铃薯来源GP和拟南芥来源GP的氨基酸序列高度同源的其它A类GP的耐热性。通过使用本发明方法,可以制备来源于马铃薯和拟南芥以外其它生物物种的耐热化GP。
根据本发明,提供耐热化GP,其中酶蛋白降解被抑制并且保存稳定性提高。
