Description
技术领域
本发明涉及生物交联的技术领域，具体涉及一种蛋白与核酸共价连接的方法。
背景技术
蛋白核酸复合物由于具备了蛋白质功能多样性以及核酸的可编程性，使其在生物技术上研究十分广泛。目前蛋白核酸复合物在核酸纳米结构上构建的多酶体系、固相载体如生物芯片上的蛋白固定、生物分子递送、高分辨成像技术上已有大量工作报导。
目前蛋白核酸连接方法主要有以下几种：生物素与链霉亲和素的高亲附作用、镍离子介导的次氮基三乙酸(NTA)与六聚组氨酸的结合、特异性抗原抗体相互作用、异源双官能交联剂介导、适配体-蛋白介导的组装等。但上述各种方法都不可避免的需要对蛋白或核酸进行特定基因、功能进行修饰，其过程比较繁琐，易对DNA结构或蛋白的固有性质造成损失，以及修饰连接时出现非特异性结合、随机性大、连接效率低等问题。
实际运用中需依据不同目的选择不同的修饰方法，然而这并不能完全满足实际要求，这也是限制蛋白核酸复合物发展的一个瓶颈，因此目前蛋白核酸连接技术有待发展，急需要一种稳定、高效、反应条件温和、易于使用的共价定点连接技术。
发明内容
有鉴于此，本发明致力于提供一种蛋白或肽与核酸共价连接的方法，克服了现有技术中几种常用的蛋白核酸连接方法存在的操作过程繁琐、易损伤蛋白或核酸的性质、随机性大、连接效率低等问题，实现了稳定、高效、定点、定向共价连接目标蛋白或肽与目标核酸的目的。
为了达到本发明的目的，采用了下述的技术方案：
本发明第一方面提供了一种蛋白或肽与核酸共价连接的方法，包括以下步骤：
(1)目标蛋白或肽与Trwc酶形成融合蛋白；
(2)融合蛋白中Trwc酶催化目标蛋白或肽与目标核酸共价连接。
本发明的发明人发现了现有技术中几种常用的蛋白核酸连接方法存在着操作过程繁琐、易损伤蛋白或核酸的性质、随机性大、连接效率低等问题。因此，经过不断的努力研究发现了可以利用Trwc酶作为连接载体催化目标蛋白或肽与目标核酸共价连接，先将Trwc酶与目标蛋白制备成融合蛋白，融合蛋白中的Trwc酶座位连接载体去结合目标核酸，以此达到了目标蛋白和目标核酸通过Trwc酶共价连接的目的。
Trwc为DNA链转移酶(Trwc蛋白酶)，因为最初是在质粒弛缓复合物中发现的，也称为弛缓酶，Trwc酶发现于质粒R388。Trwc DNA链转移酶活性的决定因素位于其N端结构域(1-293)，而C端结构域包含5’→3’DNA解旋酶活性。在体外，全长Trwc及其N端结构域都能以类似于I型拓扑异构酶的方式裂解含nic位点的单链寡核酸和完整的链转移反应。
示例性地，Trwc酶包括其相关突变体或者部分结构域，所述突变体或部分结构域仍然具有Trwc酶的功能能够识别、剪切和连接特定序列的DNA。
示例性地，所述的目标蛋白可为多聚蛋白、寡聚蛋白、单体蛋白等。按其来源可为植物蛋白、动物蛋白或人工合成蛋白等。所述目标肽可为有生物活性多肽或人工合成多肽等。示例性地，所述目标肽可为有生物活性多肽或人工合成多肽等。例如，细胞因子模拟肽、抗菌性活性肽、用于心血管疾病的多肽、其它药用小肽以及诊断用多肽等。
本发明中，对目标蛋白或肽不作具体限定，可以根据实际需要进行选择。
本发明利用Trwc酶在催化DNA链的断裂和结合方面的性质，将Trwc酶先与目标蛋白或肽组装成融合蛋白，再利用融合蛋白中的Trwc酶催化共价连接目标核酸，实现了稳定、高效、定点、定向共价连接目标蛋白或肽与目标核酸。
在本发明一种具体实施方式中，所述Trwc酶的氨基酸序列如SEQ ID NO.1所示：MLSHMVLTRQDIPRAASYYEDPADDYYAKDPDASEWQGKGAEELGLSGEVDSKRFRELLAGNIGEGHRIMRSATRQDSKERIGLDLTFSAPKSVSLQALVAGDAEIIKAHDRAVARTLEQAEARAQARQKIQGKTRIETTPNLVIGKFRHETSRERDPQLHTHAVILNMTKRSDGQWRALKNDEIVKATRYLGAVYNAELAHELQKLGYQLRYGKDGNFDLAHIDRQQIEGFSKRTEQIAEWYAARGLDPNSVSLEQKQAAKVLSRAKKTSVDREALRAEWQATAKELGIDFS或其同源序列。本发明中的Trwc蛋白酶有4处碱基位点进行突变，突变位点为G13P、G22P、G31P、G141P(序列中横线加粗的氨基酸突变位点)，突变后的Trwc蛋白酶性质更加稳定。

示例性地，所述n为0-30个碱基，例如n可以为0、1、2、3、4、5、6、7、8、9、10、11、12、13、14、15、16、17、18、19、20、21、22、23、24、25、26、27、28、29或30个碱基。
在本发明一种具体实施方式中，所述Trwc酶识别的核酸序列为ATTGACTTACGCGCACCGAAAGGTGCGTATTGTCTATAGCCCAGTTTA(SEQ ID NO：4)，画横线部分为Trwc酶的识别位点。
在本发明一种具体实施方式中，所述Trwc酶识别的核酸序列为ATTGACTTACGCGCACCGAAAGGTGCGTATTGTCTATAGCCCAGTTTAAGGATAGG(SEQ ID NO：5)，画横线部分为Trwc酶的识别位点。
进一步，在本发明提供的技术方案的基础上，所述目标蛋白或肽与Trwc酶直接连接或通过柔性连接肽连接形成融合蛋白。

进一步，所述目标蛋白或肽与Trwc酶直接连接或通过柔性连接肽连接；更优选通过柔性连接肽连接。
进一步，所述Trwc酶的氨基酸序列如SEQ ID NO.1所示或其同源序列。
在本发明的一个具体实施方式中，所述目标蛋白为链球菌G蛋白、荧光蛋白ECFP、荧光蛋白Venus、丙酮酸氧化酶、磷酸乙酰转移酶中的一种。
蛋白核酸复合物不会影响或增强目标蛋白的功能。示例性地，荧光蛋白与目标核酸形成复合物后，经过检测发现其显示的荧光强度不变或者荧光强度增强。某蛋白酶与目标核酸形成复合物后，蛋白酶的活性不受影响或酶活力增强。
蛋白核酸复合物可以应用于蛋白类药物的靶向运输。示例性地，蛋白类药物作为生物大分子不易进入肿瘤细胞，并且在体内循环过程中较易被生物降解。DNA结构可被用作蛋白类生物大分子的运输载体，例如将DNA结构和蛋白类药物制备成蛋白核酸药物复合物，具有结构可设计，尺寸可控，位点精确定位，生物相容性好，无明显细胞毒性，易于功能化修饰等优势，用以实现对蛋白类药物的靶向运输和可控释放，具有重大的理论和实际意义。
本发明第三方面提供了蛋白核酸复合物的制备方法，包括以下步骤：

进一步，所述目标蛋白或肽与所述DNA拓扑异构酶直接连接或通过柔性连接肽连接；更优选通过柔性连接肽连接。
融合蛋白作为制备蛋白核酸复合物的中间产物，仅需融合一个小蛋白(Trwc酶仅有约293个氨基酸组成)，对目标蛋白几乎无影响，融合蛋白不仅会保留目标蛋白与Trwc酶两者的功能，而且可能会增强目标蛋白的功能。
本发明第五方面提供了Trwc酶在目标蛋白或肽与目标核酸连接中的用途。
本发明采用上述技术方案具有以下有益效果：
(1)本发明提供了一种蛋白或肽与核酸共价连接的方法，利用Trwc酶能够识别、剪切和连接特定的目标核酸序列且能与目标核酸共价连接的性质，实现了稳定、高效、定点、定向共价连接目标蛋白或肽与目标核酸的目的，克服了目前现有技术中众多蛋白核酸连接出现的问题。
(2)本发明提供的蛋白或肽与核酸共价连接的方法不会影响目标蛋白或肽与目标核酸的结构或性能，可以应用于增强目标蛋白的功能、蛋白类药物的靶向运输等方面。
(3)本发明提供了蛋白核酸复合物及其制备方法，通过Trwc酶催化连接的方式获得，反应条件温和，反应步骤简单，耗时短，无需引入任何化学试剂，只需加入金属离子，适合产业化推广。

实施例3ECFP与Trwc酶的融合、表达
本实施例中以荧光蛋白ECFP作为目标蛋白，将其与Trwc蛋白进行融合与表达。

将所得蛋白核酸复合物ECFP-Trwc-核酸进行SDS-PAGE电泳确认，其结果如图3所示。图3中从左向右的通道分别表示：泳道1为融合蛋白对照；泳道2为ECFP-Trwc-核酸复合物。从图3中可以看出，通道2中相较于对照存在着明显的滞后条带，说明本实施例中的目标蛋白与目标核酸已共价连接形成蛋白核酸复合物ECFP-Trwc-核酸。
实施例5
验证突变前Trwc蛋白酶、与突变后Trwc蛋白酶(突变位点为G13P、G22P、G31P、G141P)的蛋白稳定性差异，将前述突变前后的两种Trwc蛋白酶配制成澄清溶液于4度放置一周后观察，观察结果如图4所示。
从图4可以看出，左侧离心管管内突变后的蛋白溶液依然保持澄清的状态，而右侧离心管管内突变前的蛋白蛋白溶液有明显沉淀现象，证明了突变后的Trwc蛋白酶性质更加稳定。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换等，均应包含在本发明的保护范围之内。
