Description
技术领域
本发明涉及生物技术领域和肝素生物合成领域,具体涉及一种磺基转移酶及其应用。
背景技术
肝素(Heparin)属于一类高度硫酸化的糖胺聚糖,具有独特的生理功能。肝素作为一种抗凝血和抗血栓药物,大量应用于手术处理和抗静脉血栓形成等临床实践中。另外肝素还具有抗平滑肌增生、抗炎、抗肿瘤以及抗自由基等作用。其结构复杂,具有生物活性多样等特点,成为近年来多糖类药物研究的热点。目前市场上的肝素获得主要依赖动物组织提取,主要是猪小肠黏膜,但是随着市场需求量的增加,动物组织提取无法满足需求。化学酶法合成肝素因为安全有效,成为新的肝素来源。
肝素的合成以葡萄糖醛酸(GlcUA)和N-乙酰葡萄糖胺(GlcNAc)二糖重复单元组成的线性多糖骨架,随后,六种肝素修饰酶对其进行一系列的修饰。多糖骨架在氨基葡萄糖N-脱乙酰基酶/N-磺基转移酶(NDST)的作用下将GlcNAc转化为N-硫磺基葡萄糖(GlcNS)。然后C5异构化酶(C5 epimerase)将GlcUA转化为艾杜糖醛酸(IdoUA),得到的多糖在2-O-硫酸基转移酶(2-OST)的作用下将2-O-硫酸基(2-O-sulfo group)引入到IdoUA/GlcUA,在6-O-硫酸基转移酶(6-OST)的作用下将6-O-硫酸基(6-O-sulfo group)引入到GlcN,在3-O-硫酸基转移酶(3-OST)的作用下将3-O-硫酸基(3-O-sulfo group)引入到GlcN,修饰后的肝素具有抗凝血活性。
磺基转移酶(sulfotransferase,ST,EC 2.8.2.-)是指催化磺基基团从PAPS上转移给各种受体分子,同时生成3'-磷酸腺苷-5'-磷酸(PAP)的一类酶。磺基转移酶存在于大多数生物组织中,可介导不同类别受体硫酸化,以实现各种生物功能,包括解毒、细胞信号转导和受体结合的调节等 。在微生物-酶法合成肝素途径中,芳基磺基转移酶IV ( Arylsulfotransferase, ASTIV, EC 2.8.2.1) 可以使用廉价的对硝基苯酚磺酸盐(PNPS)和催化量的PAP合成PAPS,这是目前肝素合成研究中常用的PAPS再生方法,该方法可以在反应体系中消除PAP对硫酸转移酶抑制的同时促进PAPS再生(图1)。目前ASTIV受体特异性和抑制机制等方面已取得一定研究进展,其表达元件数量稀少,主要来源于鼠源和人源,且表达量较低,因此挖掘新型芳基磺基转移酶,为PAPS再生系统提供新元件,对构建高效低成本的酶法合成肝素工艺具有重要意义。
例如,US20230151339A1(公开日2023年5月18日)公开一种工程化的芳基硫酸盐依赖性酶,CN114763518A(公开日2022年7月19日)公开一种发酵生产肝素的酵母工程菌的构建及其应用。但是现有技术中PAPS系统的芳基磺基转移酶来源单一、表达量较低,酶活较低,造成PAPS系统成本高,无法实现微生物-酶法合成肝素。
在微生物-酶法生产肝素中,3'-磷酸腺苷-5'磷酸硫酸(3'-phosphoadenosine-5'-phosphosulfate,PAPS)高效合成/再生系统是该方法能否实现的关键,磺基转移酶(sulfotransferase,ST,EC 2.8.2.-)是该系统中的关键酶之一,催化磺基基团从PAPS上转移给各种受体分子,同时生成3'-磷酸腺苷-5'-磷酸(PAP)的一类酶。现有酶的表达量和活力不高,挖掘新的芳基磺基转移酶,为PAPS再生系统提供新元件,对构建高效低成本的微生物-酶法合成肝素工艺具有重要意义。

具体实施方式
结合实施例,进一步阐述本发明。除非特别说明,以下实施例中使用的试剂和仪器均为市售可得产品,相关处理为常规操作。但下述实施例仅是示例,并不构成本发明的限制。
实施例1、磺基转移酶S4的表达
利用本体blast程序分析建立磺基转移酶基因容量数据库,作为目标物种蛋白质数据库,使用HMMER命令行工具训练多序列比对结果,构建隐马尔可夫数据集,使用HMM数据集体扫描目标物种蛋白质数据库,挖掘磺基转移酶基因家族未报道与未注释的新基因,获得磺基转移酶新基因S4(氨基酸序列如SEQ ID NO:1所示)。
利用隐马尔可夫模型挖掘获得磺基转移酶新基因S4,基因序列根据大肠杆菌密码子偏好性进行密码子优化(优化后的核苷酸序列为SEQ ID NO:2所示),并构建到表达载体pET32a的多克隆位点BamH I和Xhol I之间,在N端添加麦芽糖结合蛋白Mbp。
过夜培养DH5α/pET32a-Mbp-S4菌株,提取质粒pET32a-Mbp-S4,化学热激法转化到E. coli BL21 TrxB(DE3)菌株中。涂布于LB固体平板(氨苄霉素和卡那霉素抗性),培养12h后挑取单克隆进行菌落PCR验证并测序。
挑取测序正确的BL21 / pET32a -Mbp-S4单菌落于2 mL TB液体培养基中,添加100 μg/mL氨苄霉素和50 μg/mL卡那霉素,37℃,220 rpm过夜培养。按照1%接种量转接到含有相同抗性的20ml TB培养基(100 mL三角瓶)培养,测定OD600=0.6~0.8时,摇床降温到16℃,加入0.4 mmol/L IPTG(终浓度),诱导培养20 h。培养结束后,取1ml发酵液于5500 rpm,4℃条件下离心10 min,收集菌体,加入500 μL磷酸盐缓冲液重悬菌体,放置在冰上,使用超声破碎仪破碎(功率300 W,工作5s,停止3s,工作10 min),低温高速离心10 min,分离并收集破碎上清液体和不溶物,对样品进行SDS-PAGE胶图分析。
实施例2、磺基转移酶S4的纯化
培养结束后,取培养液于5500 rpm,4℃离心10min收集菌体,用缓冲液CM洗菌(Tris-HCl pH 7.4 ,20 mmol/L NaCl, 200 mmol/L EDTA ,1 mmol/L DTT),并重悬至OD=20。高压匀质破碎菌体。10000 rpm,4℃离心20 min,上清过0.45μmol/L滤膜后进行纯化。
利用淀粉树脂凝胶柱纯化目的蛋白,样品加入纯化柱后4℃旋转吸附1h。收集流穿液,用100 ml缓冲液CM洗脱杂蛋白,然后用3ml含有10 mmol/L麦芽糖的CM缓冲液洗脱目的蛋白(图2)。蛋白纯化结果用SDS-PAGE进行分析(图3)。
实施例3、磺基转移酶S4的酶学性质表征
(1)酶活检测
将20μg S4加入到含有50 μmol/L的PNPS、50 μmol/L的PAP的50 mmol/L Tris-HCl缓冲液(pH 7.0)中,用蒸馏水补齐至总体系为200 μL。使用酶标仪每间隔1 min测定400nm吸光值,利用标准曲线计算 PNP 浓度,以不添加酶的体系作为对照。
酶活力定义为:测定条件下,每分钟催化生成1μmol PNP所需要的酶量为1个酶活单位。
在重组蛋白S4的最适反应条件,即40℃,pH=7.0的缓冲体系下,测定S4纯酶的比酶活为3.3mU/mg,总酶活为13.2U/L是粗酶液的4.73倍。测定的酶活力大小如表1。
表1 磺基转移酶S4活性测定
(2)酶反应产物分析
酶修饰:取400 μg纯酶加入到含有3 mmol/L PAPS,3 mmol/L PNP,50 mmol/LTris-HC l(pH=7.0)的体系中,用蒸馏水补齐200 μL;在最适反应条件下,反应10 h;
终止反应:将上一步中反应体系置于100℃金属浴中10 min后冷却至室温;
检测:负电喷雾电离(ESI)模式下,使用超高效液相色谱(UPLC)系统(Nexera30A, Shimadzu, Kyoto, Japan)结合质谱(TripleTOF™5600,Applied Biosystem Sciex,usa)分析酶修饰产物。使用SeQuant ZIC-HILIC色谱柱(100 × 2.1 mm, 3.5 μm, Merck,Germany)进行LC鉴定,分别以10 mmol/L乙酸铵和100%乙腈为流动相A和B,流速设置为0.2mL/min,梯度为0-3 min,90% B;3-6 min,90-60% B;6-25min,60-50% B;25-30min,50% B;30-30.5 min,50-90% B;30.5-38 min,90% B。
测活反应体系以PNPS为磺基供体,生成PAPS,但是PAPS体外存在极不稳定,极易降解为PAP,由于芳基磺基转移酶参与该反应的催化作用是可逆的,其正向反应为催化磺基从PAPS转移到PNP上,并生成PNPS。使用UPLC– MS检测,在负电模式下,实验组在保留时间为0.688 min的液相峰(图4)m/z为215.98(图5),标准品在保留时间为0.68 min的液相峰(图6)m/z为215.98(图7),表明S4反应修饰后得到的产物为PNPS,进一步验证S4为芳基磺基转移酶。
