Description
技术领域
本发明涉及生物技术领域，特别涉及一种植酸酶突变体、其制备方法及应用、编码该植酸酶突变体的DNA分子、载体、宿主细胞。
背景技术
植酸酶是一种能水解植酸的磷酸酶类。它能将植酸磷（六磷酸肌醇）降解为肌醇和无机磷酸。此酶分为两类: 3 -植酸酶（EC. 3. 1. 3. 8）和 6 -植酸酶（EC. 3. 1. 2. 6）。植酸酶广泛存在于植物、动物和微生物中, 如玉米、小麦等高等植物, 枯草芽孢杆菌、假单孢杆菌、乳酸杆菌、大肠杆菌等原核微生物及酵母、根霉、曲霉等真核微生物中。
在谷物、豆类和油料等作物籽实中，磷的基本贮存形式是植酸磷，其含量高达 1%～3%，它占植物中总磷的 60%～80%。但是以植酸磷形式存在的磷却因单胃动物体内缺乏能分解植酸的酶而难以被利用，其利用率仅在 0%～40%，从而造成了许多问题：首先是造成磷源浪费，一方面饲料中的磷源不能得到有效利用，另一方面为了满足动物对磷的需求，又必须在饲料中添加无机磷, 提高了饲料成本；其次是形成高磷粪便污染环境。饲料中 85%左右的植酸磷会被动物直接排出体外，粪便中大量的植酸磷使水和土壤受到严重污染。另外，植酸磷还是一种抗营养因子，它在动物胃肠道的消化吸收过程中会与多种金属离子如 Zn2 +、Ca2+、Cu2+、Fe2+等以及蛋白质螯合成相应的不溶性复合物，降低了动物对这些营养物质的有效利用。
植酸酶可作为一种单胃动物的饲料添加剂，它的饲喂效果已在世界范围内得到了确证。它可使植物性饲料中磷的利用率提60%，粪便中磷排泄量减少40%，同时还可降低植酸的抗营养作用。因此在饲料中添加植酸酶对提高畜禽业生产效益及降低植酸磷对环境的污染有重要意义。
现工业化生产的植酸酶主要有来源于黑曲霉的真菌植酸酶和来源于大肠杆菌的细菌植酸酶两种。其中来源于大肠杆菌的植酸酶APPA具有高比活性及良好的消化道稳定性等特点。目前主要通过在粉末饲料直接添加或颗粒饲料后喷涂的方法应用在饲料行业。
因为目前在颗粒饲料生产过程中有一个短暂的80-90℃的高温阶段。细菌植酸酶APPA热稳定性较差，其水溶液在70℃下保温5分钟剩余酶活性低于30％，直接添加到动物饲料中进行制粒后存留酶活一般低于20%，使APPA植酸酶在颗粒饲料的应用受到限制。采用饲料制粒后植酸酶液喷涂到饲料上的方法不仅增加设备投入，而且对酶制剂的稳定性、饲料中分布均一性都无法很好的保证。因此，提高热稳定性对目前饲料用植酸酶具有重要的现实意义。
发明内容
有鉴于此，本发明提供一种植酸酶突变体，获得突变体蛋白，提高其耐热性，从而有利于植酸酶在饲料领域的广泛应用。
为了实现上述发明目的，本发明提供以下技术方案：

本发明还涉及编码上述植酸酶突变体的DNA分子。
本发明还涉及包含上述DNA分子的重组表达载体。
本发明还涉及一种宿主细胞，包含上述重组表达载体。
将上述的质粒转入宿主细胞中，重组表达的植酸酶突变体的耐热性得到显著提升。

步骤2：将步骤1获得的所述DNA分子与表达载体融合，构建重组表达载体，转化宿主细胞；
步骤3：诱导含重组表达载体的宿主细胞表达融合蛋白，分离纯化表达的融合蛋白。

下面结合实施例，进一步阐述本发明：
实施例1 耐热突变体的筛选
申请人对野生型植酸酶 APPA(氨基酸序列为SEQ ID NO:1，其编码核苷酸序列为SEQ ID NO:2)的10个位点进行突变(W46E，Q62W，G70E，A73P，T114H，N137V，D142R，S146E，R159Y，Y255D)，得到植酸酶突变体APPA-M0，其氨基酸序列为SEQ ID NO:3，参照该序列合成一个编码核苷酸序列为SEQ ID NO:4。与植酸酶APPA相比，突变体APPA-M0的耐热性得到显著提升，经75℃处理5min后，植酸酶APPA残余酶活不足10%，而突变体APPA-M0的残余酶活高于85%。
为了进一步提高植酸酶突变体APPA-M0的耐热性，申请人对其基因进行蛋白结构分析，该蛋白有两个结构域：N端的134个氨基酸残基与C端的152个氨基酸残基共同组成结构域1，剩余中间124氨基酸残基组成结构域2，保守序列和活性中心均位于结构域1中，在不破坏蛋白二级结构与活性中心的前提下，进一步对该基因进行突变。
1.1设计PCR引物M0-F1、M0-R1：
M0-F1：GGCGAATTC CAGTCAGAACCAGAGTTGAAGTT（下划线为限制性内切酶EcoRI识别位点）；
M0-R1：ATAGCGGCCGC TTACAAGGAACAAGCAGGGAT（下划线为限制性内切酶NotI识别位点）。
以APPA-M0基因（SEQ ID NO：4）为模板，利用上述引物用GeneMorph II随机突变PCR试剂盒（Stratagene）进行PCR扩增，胶回收PCR产物，EcoRI、NotI进行酶切处理后与经同样酶切后的pET21a载体连接，转化至大肠杆菌BL21（DE3）中，涂布于LB+Amp平板，37℃倒置培养，待转化子出现后，用牙签逐个挑至96孔板，每个孔中加入150ul含有0.1mM IPTG的LB+Amp培养基，37℃ 220rpm培养6 h左右，离心弃上清，菌体用缓冲液重悬，反复冻融破壁，获得含有植酸酶的大肠杆菌细胞裂解液。
分别取出40ul裂解液至两块新的96孔板，将其中一块96孔板于75℃处理5min；然后向两块96孔板中各加入80ul底物，于37℃反应30min后加入80ul终止液（钒酸铵：钼酸铵：硝酸=1：1：2），测定生成的无机磷含量。不同的突变子高温处理后保持的活性不同。
实验结果表明，有些突变对植酸酶APPA-M0的耐热性没有影响，有些突变甚至使其耐热性或酶活变得更差了，另外还有些突变虽然能提高APPA-M0对温度的耐受性，但突变后其酶学性质发生了显著的变化，这些均不符合要求。最终，申请人得到既能显著提高APPA-M0耐热性，又不会影响其酶活及原有酶学性质的突变位点：A36P，N126E，V211W，Q253Y，Q258E，S266P。
在植酸酶APPA-M0的基础上，本发明提供了分别包含A36P、N126E、V211W、Q253Y、Q258E、S266P单个突变位点的单点突变体，分别命名为PHY-M1、PHY-M2、PHY-M3、PHY-M4、PHY-M5、PHY-M6，其氨基酸序列分别为SEQ ID NO:5、SEQ ID NO:7、SEQ ID NO:9、SEQ IDNO:11、SEQ ID NO:13、SEQ ID NO:15，其编码核苷酸序列为SEQ ID NO:6、SEQ ID NO:8、SEQID NO:10、SEQ ID NO:12、SEQ ID NO:14、SEQ ID NO:16。
本发明进一步提供了包含A36P/V211W、A36P/Q253Y、V211W/Q253Y两个突变位点组合的突变体，分别命名为PHY-M7、PHY-M8、PHY-M9，其氨基酸序列分别为SEQ ID NO:17、SEQID NO:19、SEQ ID NO:21，其编码核苷酸序列为SEQ ID NO:18、SEQ ID NO:20、SEQ ID NO:22。
本发明还提供了包含A36P/V211W/Q253Y三个突变位点组合的突变体，命名为PHY-M10，其氨基酸序列分别为SEQ ID NO:23，其编码核苷酸序列为SEQ ID NO:24。
本发明还提供了包含A36P/N126E/V211W/Q253Y四个突变位点组合的突变体，命名为PHY-M11，其氨基酸序列分别为SEQ ID NO:25，其编码核苷酸序列为SEQ ID NO:26。

与对应的单点突变体相比，分别包含A36P/V211W、A36P/Q253Y、V211W/Q253Y两个突变位点组合的植酸酶突变体PHY-M7、PHY-M8、PHY-M9，包含A36P/V211W/Q253Y三个突变位点组合的植酸酶突变体PHY-M10，以及包含A36P/N126E/V211W/Q253Y四个突变位点组合的植酸酶突变体PHY-M11的耐热性进一步得到提高，取得了意料不到的技术效果。
表2 植酸酶突变体在85℃条件下的耐热性分析
| 植酸酶突变体 | 85℃处理5min后酶活残留率 |
| APPA-M0 | 43.49% |
| PHY-M2 | 50.98% |
| PHY-M3 | 52.87% |
| PHY-M7 | 55.20% |
| PHY-M9 | 62.26% |
| PHY-M10 | 69.51% |
| PHY-M11 | 74.60% |
其中，包含N126E、V211W单点突变的植酸酶突变体PHY-M2和PHY-M3，包含A36P/V211W、V211W/Q253Y两个突变位点组合的植酸酶突变体PHY-M7和PHY-M9，包含A36P/V211W/Q253Y三个突变位点组合的植酸酶突变体PHY-M10，以及包含A36P/N126E/V211W/Q253Y四个突变位点组合的植酸酶突变体PHY-M11，在85℃条件下处理5min后，酶活残留率仍能达到50.98-74.60%，比APPA-M0普遍提高了17.2%-71.5%，耐热性更强。
综上所述，本发明提供的植酸酶突变体耐热性得到显著提高，从而有利于植酸酶在饲料中的广泛应用。
