Description

一种葡萄糖氧化酶突变体及其载体与应用
技术领域
本发明涉及基因工程技术领域，更具体地，涉及一种葡萄糖氧化酶突变体及其载体与应用。
背景技术
葡萄糖氧化酶(glucose oxidase，GOD)在有氧条件下能专一性地催化β-D-葡糖生成葡萄糖酸和过氧化氢。GOD是同型二聚体分子，含有2个黄素腺嘌呤二核苷酸(FAD)结合位点。每个单体含有2个完全不同的区域：一个与部分FAD非共价但紧密结合，主要为声折叠；另一个与底物β-D-葡萄糖结合，由4个α-螺旋支撑1个反平行的β-折叠。葡萄糖氧化酶在自然界分布广泛，具有反应效率高的特点，催化特异性强的特点，在食品行业，饲料添加等方面得到广泛应用。葡萄糖氧化酶是一种以β-D-葡萄糖为底物的脱氢类酶制剂，因其在酶反应过程中消耗大量氧，形成葡萄糖酸具有酸化剂性质等特征被广泛应用于食品、养殖、医药等行业。饲料中添加葡萄糖氧化酶能有效改善动物肠道健康、提高饲料利用率、促进动物生长和增强机体的抗病能力，是一种绿色、安全、无毒副作用的饲料添加剂。随着近年来GOD不断的发展应用研究，其在食品、养殖和医药工业中应用已取得较大进展。
葡萄糖氧化酶最早发现于20世纪初，之后在1928年，Muller在黑曲霉的无细胞提取液中首次发现葡萄糖氧化酶，并对其催化机理进行较为深入的研究；在1936年，Keilin D等人首次于灰绿青霉(Penicillium glaucum)中发现葡萄糖氧化酶。顾磊等人使用毕赤酵母异源表达黑曲霉来源葡萄糖氧化酶，胞外酶活达到52U/mL，同时通过分子伴侣改造，使酶活活力到达1972.9U/mL，为近年来最高。微生物来源的GOD主要以黑曲霉和青霉为主，相对于青霉，黑曲霉产的GOD具有热稳定性好，底物特异性强等优点。野生型黑曲霉GOD比活力低，生产成本高，限制了其产业化应用。CN 105002147A公开了表达量提高的突变葡萄糖氧化酶及其编码基因和应用，通过定点突变，使葡萄糖氧化酶的氨基酸序列突变位点为Y76C和Q279K，提高了表达量，且稳定性好。CN 101348794A公开了一种高活力葡萄糖氧化酶的编码基因及制备方法和应用，通过在黑曲霉GOD结构基因的1752位和2272位通过重叠PCR引入两处突变，连接于表达载体，提高了突变酶的酶活。CN103525778公开一种催化活性提高的葡萄糖氧化酶突变体，比野生型葡萄糖氧化酶提高了2.5倍。
发明内容

实施例1、黑曲霉(Aspergillus niger)葡萄糖氧化酶(GOD)基因的优化与载体构建
黑曲霉Aspergillus niger GIM 3.452(CICC 2377)的葡萄糖氧化酶(GOD)基因(Genebank:FJ979866.1)，其核苷酸序列如SEQ ID NO:2所示，其氨基酸序列如SEQ ID NO:1所示。
通过大量前期研究发现黑曲霉表达工程菌表达量低，操作复杂，难以进行突变高通量筛选。同时发现大肠杆菌表达系统表达葡萄糖氧化酶不具备活性，不能进行突变筛选。而毕赤酵母是一种成熟的真核微生物外源蛋白表达平台，具有以下特点：生长迅速并且培养廉价；简单容易操作，便于实验进行突变和高酶活筛选；作为一种真核生物，具备翻译后蛋白加工能力，在毕赤酵母合成的蛋白更有可能得到正确的加工、折叠与正确组装成有功能的蛋白分子。毕赤酵母表达黑曲霉葡萄糖氧化酶在发酵罐可以达到较高的水平，但是与实际生产还是有距离。通过对葡萄糖氧化酶基因进行针对毕赤酵母密码子优化和突变来提高氧化酶酶活，进而达到工业生产。针对毕赤酵母密码子偏好性进行优化，优化后的核苷酸序列如SEQ IDNO:3所示，分别在葡萄糖氧化酶优化基因(GOX)的5’端和3’端引入EcoRI和XbaI酶切位点，并连接至Puc57-amp载体上，将GOX-Puc57接种至LBA培养基，培养24小时候，提取质粒，用EcoRI和XbaI酶切，切胶回收目的基因片段，产物纯化回收，分别连接到表达载体pPICzαA和pPGAPzαA，得到表达载体pPICzαA-GOX和pGAPzαA-GOX。
实施例2、葡萄糖氧化酶基因定点突变
以上述pGAPzαA-GOX为模板，引入定点突变并转化毕赤酵母X33
根据葡萄糖氧化酶三维结构信息，经大量研究认为氨基酸序列的第34、51、60、90、106、243、420、561位氨基酸对葡萄糖氧化酶酶活具有重要影响，对上述位点进行饱和突变，将所述的位点饱和突变得到的酵母重组转化子用牙签逐个挑至24孔板，每个孔中加入1mL含有BMGY培养基，30℃，220rpm培养24h左右，离心去上清。再分别加入1.6mL BMMY培养基进行诱导培养。培养24h后，离心取上清，将上述上清液分别取出200μL至96孔板，进行高通量筛选。
葡萄糖氧化酶高通量测定方法是通过一种小体系结合96孔板比色测定葡萄糖氧化酶活力的方法.经实验证明,在96孔板内,波长540nm处,反应时间增加到5分钟，氧化型邻联茴香胺与光密度(OD)值有很好的线性关系；通过加样回收实验发现,其回收率为98.5％～103.2％,相对标准差为1.8％；通过精密度分析实验发现该方法测量样品的精密度与普通邻—联茴香胺分光光度法，其测定的结果与现行国家标准测定葡萄糖氧化酶方法所得到的结果差异率小于6％(如下表1所示)。
