Description
技术领域
本发明属于生物化学分析检测技术领域,具体涉及一种体外检测OGT酶活 性的方法,即一种O-连接-N-乙酰氨基葡萄糖基转移酶OGT的酶活性的检测方 法。
背景技术
O-连接-N-乙酰氨基葡萄糖基转移酶OGT负责催化真核细胞内蛋白质丝氨 酸和苏氨酸侧链羟基的O连N-乙酰-葡糖胺修饰,简称为O-GlcNAc糖基化修饰。 人体内能够被OGT酶介导O-GlcNAc糖基化修饰的底物蛋白质数量多,且涉及 人体细胞活动和生物反应的多个层面,参与调控涉及STAT3、p53等重要转录因 子介导的基因表达、调控组蛋白和细胞周期蛋白等介导的细胞周期、通过直接或 者间接的细胞内底物蛋白质修饰控制细胞内关键蛋白或酶的生物活性而影响细 胞内信号通路的转导和活性,最终影响人体的基本生理功能和病理变化反应。人 体体内正常水平的O-GlcNAc糖基化修饰支持细胞生理活动的正常调控,而异常 体内异常的O-GlcNAc糖基化修饰水平与多种肿瘤的发生发展有着紧密联系。肿 瘤病理组织样本研究已经证明,在结直肠癌、乳腺癌、前列腺癌、肺癌、肝癌、 胰腺癌、膀胱癌等肿瘤细胞中都呈现有过度的OGT酶活性及其介导的高度 O-GlcNAc糖基化修饰。因此,OGT酶活性的检测及其抑制剂的发现是开发其相 关肿瘤诊断方法和药物的关键。
目前市场在售的OGT酶活性检测试剂盒非常有限,其中一款为基于生物冷 发光的UDP-Glo检测方法,其是通过对OGT酶反应副产物UDP的间接检测, 容易受到样品中UDP的干扰,且其生产成本和销售价格较高。学术研究中常用 的OGT酶活性检测方法有液相色谱法、质谱法、荧光偏振法、点击化学法等。 液相方法是对OGT糖基化底物极性改变的检测,质谱法是对OGT糖基化底物 分子量改变的检测,两种方法对样品的前处理要求较高,很容易受到样品中其他 物质的干扰。荧光偏振法中涉及到对供体底物或受体底物的修饰,不能体现OGT 的天然酶活性,且荧光底物合成较为繁琐。点击化学方法中利用非天然的OGT 酶供体底物如叠氮功能化修饰的UDP-GlcNAz,随后采用炔基功能的信号分子与 其发生点击化学反应来检测OGT酶活性的方法,但该法涉及的化学合成步骤繁 琐,其中叠氮的合成过程中存在安全隐患,同时生产成本较高,并且非天然的供 体底物不具有与天然底物同样的活性。此外,也有报道以同位素标记的供体底物 来检测OGT对底物蛋白质的活性,但其具有潜在的放射性危害,对环境不友好, 对设备环境等要求很高,难以推广使用。

下面结合附图和实施例对本发明作更进一步的说明。但应当理解这些实施例 并非限制本发明的范围。根据下述实施例,可以更好的理解本发明。然而,本领 域的技术人员容易理解,实施例所描述的具体的物料配比、工艺条件及其结果仅 用于说明本发明,而不应当也不会限制权利要求书中所详细描述的本发明。
在本发明中所使用的术语,除非另有说明,一般具有本领域普通技术人员通 常理解的含义。
在以下实施例中,未详细描述的各种过程和方法是本领域中公知的常规方法。
实施例1高活性OGT底物多肽ZO3-S371A的设计与制备
本实施例中,高活性OGT底物多肽ZO3-S371A的氨基酸序列来源于NCBI 数据库中的ZO3蛋白质序列(NP_001254489.1,SEQ ID No.1)。选择SEQ ID No.1 中对应第357-371位的氨基酸序列,将该段序列的羧基末端氨基酸改变为丙氨酸, 在其氨基末端通过添加一个甘氨酸和一个半胱氨酸得到本发明中具备偶联功能 的高活性OGT底物多肽ZO3-S371A(SEQID No.2)。ZO3-S371A多肽的具体制 备方法如下:
ZO3-S371A多肽的制备采用基于Fmoc保护策略的多肽固相合成原理,使用Symphony多肽固相合成仪进行合成。构成SEQ ID No.2多肽的所有氨基酸均为 Fmoc保护的标准氨基酸并用二甲基亚酰胺溶解,浓度均为0.2M,称取Rink amide Resin固相树脂50mM为固相载体。合成反应过程中Fmoc的脱保护试剂 为溶解于二甲基亚酰胺的20%的哌啶溶液、缩合试剂为0.16M的TBTU,每个氨 基酸的偶联缩合时间为1h。仪器合成结束后将含有多肽的树脂转入圆底烧瓶, 加入10mL切割试剂,所用的切割试剂为TFA/H2O/TIPS/DTT(9∶0.5∶0.25∶0.25, v/v/v),充氮气保护,于室温磁力搅拌4小时。切割完成后通过过滤装置去除树 脂,滤液用冰乙醚收集缓慢进行沉淀,5000rpm离心收集沉淀,于冷冻干燥仪 器上干燥后得到粗品。将该粗肽样品溶解于纯水,使用100%的乙腈为流动相A, 100%的超纯水为流动相B,使用半制备高效液相色谱法HPLC及反向C18色谱 柱进行制备纯化,收集组分并质谱确定目标产物,冻干称重。
称取1mg上述多肽纯品,溶解于1mL纯水,过滤后通过HPLC进行检测, 通过峰面积归一法对所得多肽的纯度进行计算,纯度大于95%。同时采用质朴分 析确定产物的分子量。
图2为经过纯化后的OGT高活性底物多肽ZO3-S371A的HPLC分析图,数 据分析表明其纯度达到95%以上。
图3为纯化后的OGT高活性底物多肽ZO3-S371A的质谱分析图,分子量 与预期值相符为1917Da。
对所获得的OGT底物多肽ZO3-S371A采用UDP-Glo方法进行活性测定, 以广泛使用的OGT底物多肽RBL2为参照,两种多肽在100uM浓度下测定结 果表明基于本发明底物多肽ZO3-S371A的实验组荧光值为74500RLU,而基于 RBL2多肽的对照组荧光值为14300RLU,因此本发明底物多肽的活性是对照底 物多肽的5倍,说明本发明获得的底物多肽ZO3-S371A具有高活性的性质,有 利于提高OGT酶活检测技术的灵敏度和准确度。
实施例2高活性OGT底物多肽ZO3-S371A的固定化及封闭
将所述的OGT底物多肽ZO3-S371A溶解于固定缓冲液,该缓冲液含有0.1 mMNa3PO4,0.15mM NaCl,10mM EDTA,pH 7.2,溶解后多肽底物的浓度为50 ug/ml。含有活化的马来酰亚胺基团的96孔板购自赛默飞(货号15150),使用洗 涤缓冲液200ul/孔洗涤孔板三次,弃去洗涤缓冲液。所述的洗涤缓冲液含有0.1 mM Na3PO4,0.15mM NaCl,0.05%tween-20,pH 7.2。将前述步骤中溶解的多肽底 物与含有马来酰亚胺的96孔板进行孵育,时间2h,温度为25℃。孵育完成后, 弃去上清,使用洗涤缓冲液200ul/孔洗涤孔板三次,弃去洗涤缓冲液。配置封闭 液为10ug/ml的半胱氨酸水溶液,每孔加入200ul的封闭液,室温条件下孵育 1h。孵育完成后,使用洗涤缓冲液200ul/孔洗涤孔板三次,弃去洗涤缓冲液。 OGT的多肽底物固定完成。
实施例3 OGT对ZO3-S371A糖基化的酶促反应
OGT酶反应的缓冲液体系为50mM Tris-HCl,1mM DTT,12.5mM MgCl2, pH 7.5。OGT酶的供体底物为UDP-GlcNAc。在上述的OGT酶反应体系中加入 OGT的供体底物UDP-GlcNAc,使其终浓度达到100um/L,进一步加入纯化的 OGT酶0.5ug或者粗酶5ug,充分混匀。将上述100ul/孔的酶反应混合液加入 到固定有OGT底物多肽的96孔板,摇床转速200rpm,温度30℃,孵育3h。
实施例4以WGA-HRP检测糖基化的OGT底物多肽及其特异性和灵敏度
为了确定以WGA-HRP的酶促显色方式检测OGT糖基化多肽的灵敏度,本 实施例中采用已经OGT糖基化的标准底物ZO3-S371A-O-GlcNAc,按照实施例2中所述的方法将不同浓度的ZO3-S371A-O-GlcNAc固定于96孔板,浓度从低 到高依次为0、0.78、1.56、3.125、6.25、12.5、25、50ug/ml。上述多肽固定结 束后,每孔加入100ul且浓度为10ng/ml的WGA-HRP作为O-GlcNAc糖基化 多肽的标记物,于室温条件下孵育1h。孵育结束后使用洗涤缓冲液200ul/孔洗 涤孔板三次,弃去洗涤缓冲液。每孔加入100ul的HRP酶底物TMB,室温下孵 育10分钟,随后每孔加入100ul浓度为2M的硫酸溶液作为HRP酶反应终止 液,此时多孔板中的溶液呈现黄色。通过酶标仪检测多孔板中液体的吸光值,设 定波长为450nM。
对比例1以WGA-HRP检测未经糖基化的OGT底物多肽及其特异性和灵 敏度
本实施例中同实施例4,区别在于采用未经OGT糖基化的多肽底物 ZO3-S371A。
图4为实施例4及对比例1关于WGA-HRP检测OGT糖基化的多肽的关键 数据。在不含有O-GlcNAc糖基化多肽的对照组对比例1中,随着多肽底物浓度 增加,检测到的显色信号数值保持不变,而含有O-GlcNAc糖基化的实验组实施 例4中,随着糖基化多肽底物浓度的增加(相当于OGT酶活性在增加),检测到 的显色信号数值增加,表明该方法对OGT糖基化多肽和非糖基化多肽的具有高 选择性。在O-GlcNAc糖基化多肽浓度为3.125ug/ml的条件下即检测出显著的 数值增加,因此基于WGA-FITC的检测方法,可以检测到至少310ng的被OGT糖基化的多肽,表明本发明提供的方法具有很高的灵敏度。
实施例5以WGA-FITC检测OGT糖基化的多肽及其灵敏度
为了确定以WGA-FITC的荧光方式检测OGT糖基化多肽的灵敏度,本实施 例中采用已经OGT糖基化的标准底物ZO3-S371A-O-GlcNAc,按照实施例2中 所述的方法将不同浓度的ZO3-S371A-O-GlcNAc固定于96孔板,浓度从低到高 依次为0、0、0.5、1、2、3、4、5ug/ml。上述多肽固定结束后,每孔加入100ul 的浓度为10ng/ml的WGA-FITC作为O-GlcNAc糖基化多肽的检测物,于室温 条件下孵育1h。孵育结束后使用洗涤缓冲液200ul/孔洗涤孔板三次,弃去洗涤 缓冲液,每孔加入200ul的PBS缓冲液。酶标仪检测WGA-FITC荧光信号的 检测,设定的激发波长为485-500nM,发射波长为510-520nm。
根据实施例4与对比例1的结果,已经反映出,对照组的未糖基化底物并不 会被WGA所识别,因此可以类推如果采用本实施例中的WGA-FITC的荧光方 式检测,未糖基化底物理应也是不会被WGA所识别的。
图5为实施例5关于WGA-FITC检测OGT糖基化的多肽的关键数据。该结 果显示,在无O-GlcNAc糖基化多肽存在的条件下(相当于无OGT酶活性的条 件下),读取的荧光数据本底值较低,而当O-GlcNAc糖基化多肽浓度增加时(相 当于OGT的酶活性在不断增加的条件下),荧光值数据随之增加。在O-GlcNAc 糖基化多肽浓度为5ug/ml的条件下即检测出显著的数值增加,因此基于 WGA-FITC的检测方法,可以检测到至少500ng的被OGT糖基化的多肽,表明 本发明提供的方法具有很高的灵敏度。
实施例6以基于抗体标记发光法检测OGT糖基化的多肽及其灵敏度 本发明提供的方法也可以通过抗体标记发光法进行检测。
为了确定以抗体标记发光法检测OGT糖基化多肽的灵敏度,本实施例中采 用已经OGT糖基化的标准底物ZO3-S371A-O-GlcNAc,按照实施例2中所述的 方法将不同浓度的ZO3-S371A-O-GlcNAc固定于96孔板,浓度从低到高依次为 0、0.078、0.156、0.3125、0.625、1.25、2.5、5ug/ml。上述多肽固定结束后,每 孔加入100ul且浓度为0.25ug/ml的小鼠单克隆抗体RL2作为O-GlcNAc糖基 化多肽的标记物,于室温条件下孵育1h。孵育结束后使用洗涤缓冲液200ul/孔 洗涤孔板三次,弃去洗涤缓冲液。每孔加入100ul且浓度为1ug/ml的HRP标 记的山羊抗小鼠二级抗体,于室温条件下孵育1h。孵育结束后使用洗涤缓冲液 200ul/孔洗涤孔板三次,弃去洗涤缓冲液。每孔加入100ul的HRP酶底物TMB, 室温下孵育10分钟,随后每孔加入100ul浓度为2M的硫酸溶液作为HRP酶 反应终止液,此时多孔板中的溶液呈现黄色。通过酶标仪检测多孔板中液体的吸 光值,设定波长为450nm。
图6为实施例6关于抗体标记显色法检测OGT糖基化的多肽的关键数据。 该结果显示,在无O-GlcNAc糖基化多肽存在的条件下(相当于无OGT酶活性 的条件下),读取的显色吸光值数据本底值较低(OD450=0.047),而当O-GlcNAc 糖基化多肽浓度增加时(相当于OGT的酶活性在不断增加的条件下),吸光值数 据随之增加。在O-GlcNAc糖基化多肽浓度为0.3125ug/ml的条件下即检测出显 著的数值增加,因此基于抗体标记显色法的检测方法,可以检测到至少31.25ng 的被OGT糖基化的多肽,表明本发明提供的方法具有很高的灵敏度。
以上实施例说明,本发明提供的体外检测OGT酶活性的方法,灵敏度高, 特异性强,制备简单,成本低。该方法可在体外检测OGT酶活性中的应用。此 外,还可以根据上述的方法,制成对应的体外检测OGT酶活性的装置,如装置 包括检测板、检测盒及试纸条等。
以上所述仅是本发明的优选实施方式,应当指出:对于本技术领域的普通技 术人员来说,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些 改进和润饰也应视为本发明的保护范围。
