Abstract
本发明涉及一种用于医疗应用的α‑1‑微球蛋白衍生蛋白。
Description
技术领域
本发明涉及具有改善特性的人α-1-微球蛋白蛋白质的修饰的变体,以及这些变体在医学治疗和诊断中的应用。发明人惊讶地发现,引入特定的氨基酸取代和/或添加特定的N端延伸(N-terminal extension)会在稳定性、溶解性、以及与血红素的结合这些方面赋予α-1-微球蛋白改善的特性。
背景技术
A1M(α1-微球蛋白)是具有胞外组织清洁功能的低分子量蛋白(等人,1977;和Gram,2014)。它存在于鱼类、鸟类、啮齿类、哺乳动物和其他脊椎动物的所有组织和器官中。A1M主要在肝脏中合成,但也以更低的速率在身体的大部分其他细胞中合成。它由α1-微球蛋白-bikunin前体基因(AMBP)编码,并在所有细胞和物种中翻译为与另一种蛋白bikunin一起的连续肽前体(Kaumeyer等人,1986)。但是,两种蛋白通过蛋白酶切割分离,加工,并作为具有不同功能的两种不同蛋白分泌到血液中(Lindqvist等人,1992;Bratt等人,1993)。普遍存在的A1M和bikunin的共合成的原因仍然是未知的。在血液中,约50%的A1M以游离的单体形式存在,剩余的50%以与免疫球蛋白A、白蛋白和凝血酶原共价结合的高分子量络合物存在(等人,1997)。
A1M是单结构域的183-氨基酸的糖基化蛋白。最近公布了大肠杆菌中表达的A1M的巨大片段的晶体结构(Meining和Skerra,2012)。基于其结构,A1M属于脂质运载蛋白家族,具有50个或更多个成员,来自动物、植物和细菌(Flower,1996;等人,2006)。脂质运载蛋白具有一个共同的三维结构,其由8条反平行的β链组成,形成具有一个封闭端(底部)和一个敞开端(顶部)的桶。该桶在大部分脂质运载蛋白中充当疏水性配体的口袋。组成该桶敞开端边沿的4条环(环1-4)在各种脂质运载蛋白之间的长度变化和组成变化很大。在A1M中,位于这些环上或者位于该桶内侧的少量氨基酸侧基团已经显示对于该蛋白确定的功能是重要的。因此,位于环1短螺旋上游离的半胱氨酸C34具有负还原电势,并赋予A1M还原酶特性(Allhorn等人,2005)。两个酪氨酸残基Y22和132显示被自由基氧化产物体外共价修饰(等人,2007)。4个赖氨酸残基K69、92、118和130调节还原酶活性(Allhorn等人,2005),影响与游离血红素基团的结合(Rutardottir等人,2015),并在从具有低分子量黄棕色不均匀物质的人尿和羊水纯化的A1M上共价修饰(等人,1999;Sala等人,2004)。
采用还原酶活性、自由基清除特性和血红素结合特性,A1M充当保护细胞和组织免受氧化性损害的抗氧化剂。A1M显示会保护体外血细胞培养物、胎盘组织和皮肤免受血红蛋白、血红素和活性氧物质(ROS)的氧化性损害(Olsson等人,2008;May等人,2011;Olsson等人,PloS One 2011;Olsson等人,ARS2012)。A1M还在大鼠和兔中显示出在输注血红蛋白之后针对胎盘和肾脏组织损伤的体内保护作用(Sverrison等人,2014;等人,2015)。在一系列报道中,显示血红蛋白和氧化应激参与先兆子痫(一种严重的妊娠并发症)的发病机理(Centlow等人,2008;Hansson等人,2013),并且肝脏、胎盘和血浆中的A1M-mRNA水平和蛋白水平在患有先兆子痫的孕妇中升高(Olsson等人,2010;Anderson等人,2011)。因此,建议可使用A1M作为治疗剂来治疗患有先兆子痫的孕妇以缓解氧化性损害,并因此缓解该疾病的临床症状(Olsson等人,2010)。
在大肠杆菌中开发了一种重组人A1M的产生方法,并显示具有还原酶特性、自由基结合特性和血红素结合特性(Kwasek等人,Allhorn等人,2002;2005;等人,2007)。该重组A1M变体在先兆子痫绵羊模型中确实显示出体内治疗效果(等人,2014)。然而,尽管会起作用,但是大肠杆菌表达的重组A1M缺乏糖基化,并且与从尿或血浆纯化的人A1M相比具有差的溶解性和稳定性。蛋白缺乏稳定性和溶解性会限制其作为用于人类使用的药物的应用,这主要是由于难以获得高度浓缩的溶液和在生理pH和盐条件下的缓冲液中长期储存的条件。
因此,需要开发与人A1M结构类似、但是在稳定性和溶解性上具有改善的特性的蛋白。另外,该蛋白应该相对容易以适合医疗应用的量制备。
具体实施方式
本发明涉及新的α-1-微球蛋白,其具有改善的稳定性和溶解性。
使用定点诱变和加成诱变来工程化A1M-物质,其具有保留的或者可能增强的功能特性,但是具有改善的蛋白稳定性和溶解性,其容许在生理缓冲液中在高浓度下长期储存。
从本文的各实例可以看出,在选择突变的氨基酸侧基团的位置和标识时遵循四条推理路线:
1)在氧化应激、温度、氧压方面具有不同的预期环境压力的各种物种的动物同源物被表达(N=12);
2)在位于疏水性口袋的环1-4或内表面的位置处的56个依次排列的A1M-同源物中频繁发生的单氨基酸取代被引入人类基因构建体中并进行表达(N=3);以及
3)对位于有利位置的赖氨酰基或酪氨酸基残基进行添加或去除,这是基于它们可影响C35硫醇基的pKa(Allhorn等人,2005)或充当自由基捕获位点(等人,1999;Sala等人,2004;等人2007)的假设(N=5);4).
另外,N端带电荷的亲水性延伸的影响在一些A1M变体上进行了测试。所测试的N端延伸的设计所依据的基本原理是添加:1)用于进行纯化的标记(标签,tag)(例如His-标记),2)接头,以便将标记与A1M蛋白核心分离,3)几个(1-5个)带电荷的氨基酸侧基团,它们赋予蛋白亲水性特性以便在水溶液中获得最大的稳定性和溶解性,4)不损害A1M的生理功能。
该项目分为3个主要的阶段:
I期)对以上27种A1M变体进行表达,接着对溶解性、稳定性和功能进行分析;
II期)基于1期的结果对具有预期最佳特性的几种A1M变体进行设计、表达和分析;以及
III期)对未突变的野生型(wt)-A1M以及具有或者不具有N端带电荷的亲水性延伸的突变最成功的A1M变体进行设计、表达和分析。
如在此处将更详细地进行解释的,本发明提供A1M衍生的蛋白,其具有式I氨基酸序列:

本发明还提供一种A1M衍生的蛋白,其具有式II氨基酸序列:
X1-X2-X3-X4-X5-X6-X7-X8-X9-X10-X11-X12-X13-X14-GPVPTPPDNIQVQENF-X15-ISRIYGKWYNLAIGSTCPWLKKI-X16-DRMTVSTLVLGEGATEAEISMTST-X17-WRKGVCEETSGAYEKTDTDGKFLYHKSKW-X18-ITMESYVVHTNYDEYAIFLTKKFSRHHGPTITAKLYGRAPQLRETLLQDFRVVAQGVGIPEDSIFTMADRGECVPGEQEPEPI(式II)

X15代表Asp或Asn或Glu;
X16代表Met或Lys或Arg;

或其药学上可接受的盐,
条件是当所有X1-X14都不存在,X15代表Asn,X16代表Met,并且X17代表Arg时,那么X18不能代表Asn。
本发明还提供一种A1M的衍生物,即X1-X14-A1M,其中A1M可以是从表2(即人类、小鼠、裸鼹鼠、青蛙、鸡、兔、松鼠猴、海象、海牛、比目鱼和猩猩)所列物种获得的任何A1M,其中A1M在C端被截短,以便C端四肽序列LIPR不会形成蛋白的一部分。
从本文中的各实例可以看出,本发明发明人发现:
i)初始序列X1-X14似乎会赋予A1M改善的特性,
ii)A1M分子的点突变M41K、R66H或N17,96D会赋予改善的稳定性,并保持A1M的功能,
iii)突变(M41K+R66H)、(M41K+N17,96D)、(R66H+N17,96D)和/或(M41K+R66H+N17,96D)显示增加的溶解性和/或稳定性,并保持功能,
iv)突变(R66H+N17,96D)在所进行的实验中具有最佳的总体性能,
v)对具有突变(R66H+N17,96D)并具有初始序列MHHHHHHHHGGGGGIEGR(M8H5GIEGR)、MHHHHHHHHDDDDK(M8H4DK)、MHHHHHHDDDDK(M6H4DK)或MHHHHHHHH(M8H)作为N端序列的A1M进行了测试,具有M8H4DK作为N端序列的蛋白变体与其他N端延伸相比显示出更高的溶解性和/或稳定性。
vi)将A1M的C端截短似乎会赋予改善的血红素结合和降解。
值得注意的是,该N端延伸序列与具有肠激酶切割位点的His-标记类似,但是由于未包括氨基酸Ala,因此它没有将His-标记从A1M切割的能力。DDDKA中存在Ala表明肠激酶切割位点。因此可以设想,当接着重复的His-残基之后是5个带有电荷的氨基酸时,N端序列本身会赋予A1M改善的蛋白稳定性和溶解性特性。
基于这些观察结果,可以设想A1M蛋白沿以上所示线路的变化会为蛋白提供A1M功能,但在稳定性和/或溶解性方面具有改善的特征。
因此,本发明涉及如上的含有X1-X18的A1M的所有可能组合。
更具体地,以下A1M衍生的蛋白在本发明的范围内,以便所有蛋白可全长都对应于人野生型A1M;或者可以是截短的C端,即无LIPR:
Α-1-微球蛋白-一般背景
A1M在心脏中高速合成,分泌到血流中并穿过血管壁运输到所有器官的血管外空间。该蛋白还在其他组织(血细胞、大脑、肾脏、皮肤)中合成,但是速率更低。由于尺寸小,游离的A1M迅速从肾脏中的血液过滤。
A1M是脂质运载蛋白超家族的一个成员,脂质运载蛋白超家族是一组来自动物、植物和细菌的蛋白,其具有保守的三维结构但具有非常不同的功能。每种脂质运载蛋白均由折叠为具有疏水性内部的β-桶口袋的160-190个氨基酸的链组成。已知至少12种人脂质运载蛋白基因。A1M是26kDa的血浆和组织蛋白,其到目前为止已经在哺乳动物、鸟类、鱼类和青蛙中发现。通过X射线晶体分析法确定的A1M的三维结构在图10中示出。A1M在肝脏中高速合成,分泌到血液中,并迅速(T1/2=2-3分钟)穿过血管壁运输到所有器官的血管外空间。A1M在血液和间质组织中以游离的单体形式和与较大分子的共价络合物(IgA、白蛋白、凝血酶原)存在。由于尺寸小,游离的A1M迅速从肾脏中的血液过滤。然后主要部分被再吸附,但是大量的A1M被排泄到尿中。
抗氧化剂是保护性因子,其会消除氧化物或者防止有害的氧化反应。人类生物体可响应于氧化应激而产生抗氧化剂。这种内源性的抗氧化剂包括超氧化物降解酶超氧化物歧化酶(SOD)、过氧化氢降解酶过氧化氢酶和谷胱甘肽过氧化酶、以及血红素降解酶血红素加氧酶-1(HO-1)。最近显示,A1M通过作为自由基和血红素的清除剂以及氧化的还原酶和抑制剂起作用来参与防止氧化性的组织损害。几篇最近的文章显示,A1M会部分通过在线粒体中积累并保护线粒体功能来保护细胞培养物和器官外植体免受氧化性损害。确实,输注人重组A1M已经成功地用来在动物模型中对氧化应激相关的疾病先兆子痫和血红蛋白引起的肾小球损伤进行体内治疗。
A1M的序列和结构特性
人A1M的全序列是已知的。该蛋白由具有183个氨基酸残基的多肽组成。许多另外的A1M cDNA和/或蛋白已经从其他哺乳动物、鸟类、两栖动物和鱼类检测、分离和/或测序。A1M肽链的长度在各物种之间稍有区别,这主要是由于C端的变化而引起。不同的推断的氨基酸序列的比对对比显示,同一性百分比从啮齿动物或原蹄动物与人之间的约75-80%,向下到鱼类与哺乳动物之间的约45%。位置34处游离的半胱氨酸侧链是保守的。显示该基团在与其他血浆蛋白的络合物的形成中和与黄棕色生色团的结合中参与氧化还原反应(参见以下)。A1M的三维结构显示,C34与溶剂接触,并位于脂质运载蛋白口袋的开口附近(参见图10)。
在本文中,术语“α1-微球蛋白”旨在包括如在SEQ ID NO:1(人A1M)、SEQ ID NO:2(人重组A1M)和其他物种的A1M中标识的α1-微球蛋白,包括具有类似治疗活性的其同源物、片段或变体。因此,如本文所使用的A1M意思是与SEQ ID NO:1或SEQ ID NO:2具有至少80%的序列同一性的蛋白。优选的是,如本文所使用的A1M与SEQ ID NO:1或SEQ ID NO:2具有至少90%的序列同一性。甚至更优选的是,如本文所使用的A1M与SEQ ID NO:1或SEQ ID NO:2具有至少95%(例如99%或100%)的序列同一性。在一个优选方面,α1-微球蛋白与如本文所确定的SEQ ID NO:1或2一致。在序列表中给出了人A1M和人重组A1M的氨基酸序列(分别为SEQ ID No 1和2)。但是,具有如以下确认的蛋白重要部分的A1M的同源物、变体和片段也包含在如本文所使用的术语A1M中。关于比对/同一性参见以下段落。
关于比对/同一性的详细信息
本文的氨基酸残基位置是指如人血血浆中存在的人wt A1M(SEQ ID NO:1)中的位置。当提及重组A1M(其含有蛋氨酸或N-甲酰基蛋氨酸残基,其N端与wt-A1M(SEQ ID NO:2)中的初始残基-甘氨酸残基-连接)中的氨基酸残基时,或者提及突变的人A1M或其他物种的A1M中的氨基酸残基时,即使各位置由于(例如)缺失或插入而迁移,本领域技术人员也应理解如何确认与人wt-A1M(SEQ ID NO:1)中的残基对应的残基。
当产生重组蛋白时,它们最通常开始于初始Met残基,其可使用(例如)蛋氨酸氨肽酶或者具有类似活性的另一种酶除去。此处给出的A1M变体可具有或者不具有初始Met残基。
A1M的同源物
如上,还可根据本文的描述使用A1M的同源物。理论上针对本文目的所有物种的A1M均可使用,包括目前发现的最原始的A1M,其来自鱼类(比目鱼)。A1M还可以分离形式从人类、猩猩、松鼠猴、速率、裸鼹鼠、小鼠、兔、豚鼠、母牛、青蛙、鸡、海象、海牛和比目鱼得到。
就A1M的同源物、变体和片段而言,以下已经确认为蛋白抗氧化作用的重要部分:
Y22(酪氨酸,位置22,碱基对64-66)
C34(半胱氨酸,位置34,碱基对100-102)
K69(赖氨酸,位置69,碱基对205-207)
K92(赖氨酸,位置92,碱基对274-276)
K118(赖氨酸,位置118,碱基对352-354)
K130(赖氨酸,位置130,碱基对388-390)
Y132(酪氨酸,位置132,碱基对394-396)
L180(亮氨酸,位置180,碱基对538-540)
I181(异亮氨酸,位置181,碱基对541-543)
P182(脯氨酸,位置182,碱基对544-546)
R183(精氨酸,位置183,碱基对547-549)
在整个文件中氨基酸和核苷酸的编号是指SEQ ID 1;如果采用来自其他物种的其他A1M、A1M类似物或其重组序列,那么本领域技术人员应理解如何确认与SEQ ID NO:1中的氨基酸对应的氨基酸。
因此,在那些情况下,在例如A1M与SEQ ID NO:1或2之一具有80%(或者90%或95%)的序列同一性时,分子中的适当位置优选存在以上氨基酸。
人A1M在3个位置被寡糖取代,两个可能双触角碳水化连接到N17和N96的唾液酸化络合物形式的寡糖和一个连接到T5的更简单的寡糖。但是来自不同物种的A1M蛋白的碳水化合物含量变化很大,从爪蟾中完全没有糖基化到一系列不同的糖基化模式。但是,对应于人中的N96的一个糖基化位点在哺乳动物中是保守的,表明这一特定的碳水化合物可能是蛋白中比其他两个寡糖更重要的成分。
当从血浆或尿纯化时A1M是黄棕色的。该颜色由与主要位于口袋入口处的各种氨基酸侧基团共价结合的各种化合物引起。这些修饰代表被A1M体内共价捕获的有机氧化物的氧化降解产物,例如血红素、犬尿氨酸和酪氨酸基自由基。
A1M在电荷和尺寸上也是不均匀的,棕色更深的A1M分子负电荷更多。该不均匀性的可能解释是,不同的侧基团以不同的程度被不同自由基修饰,并且各修饰会改变蛋白的净电荷。共价连接的有色物质位于C34,以及K92、K118和K130,后者具有100与300Da之间的分子质量。色氨酸代谢物犬尿氨酸被发现与来自血液透析患者的尿的A1M中的赖氨酰基残基共价连接,并且在这种情况下似乎是蛋白棕色的来源[6]。合成的自由基ABTS(2,2′-连氮基-二-(3-乙基苯并噻唑啉)-6-磺酸)的氧化片段与Y22和Y132的侧链连接。
C34是A1M的反应中心。它变得非常电负性,意味着它具有由带正电荷的侧链K69、K92、K118和K130的邻近给出电子的高可能性,其会引起C34巯基的去质子化,这是氧化硫原子的先决条件。初步数据显示,C34是已知的最具有电负性的基团之一。
将在以下进行更详细的描述的具有A1M的特性的氨基酸(C34、Y22、K92、K118、K130、Y132、L180、I181、P182、R183)理论上可在另一个骨架上(例如具有相同全局折叠的蛋白(另一种脂质运载蛋白),或者完全人造的有机分子或无机分子(例如塑性聚合物、纳米颗粒或金属聚合物))上以类似的三维构型排列。
这些氨基酸中的一些的三维排列(蓝色椭圆形,赖氨酸描绘为”+“)、A1M-骨架(桶)、电子流动和自由基捕获在图10中示出。
因此,如上包含包括反应中心及其周边的结构的同源物、片段或变体是优选的。
在本公开的多肽结构中进行了修饰和改变,并仍然产生具有与原始多肽类似的功能特征的分子(例如保守的氨基酸取代)。例如,某些氨基酸可取代某一序列中的其他氨基酸而又不会显著损失活性。由于确定多肽生物功能活性的是多肽相互作用能力和性质,因此可在多肽序列中进行某些氨基酸序列取代但仍然会获得具有类似功能活性的多肽。
在进行这种改变时,可考虑氨基酸的亲水性指数。亲水性氨基酸指数在赋予多肽相互作用生物功能中的重要性在本领域中是公知的。已知某些氨基酸可取代具有类似亲水性指数或分值的其他氨基酸,而又仍然产生具有类似生物活性的多肽。基于其疏水性和电荷特征赋予每种氨基酸一个亲水性指数。那些指数为:异亮氨酸(+4.5);缬氨酸(+4.2);亮氨酸(+3.8);苯丙氨酸(+2.8);半胱氨酸/半胱氨酸(+2.5);蛋氨酸(+1.9);丙氨酸(+1.8);甘氨酸(-0.4);苏氨酸(-0.7);丝氨酸(-0.8);色氨酸(-0.9);酪氨酸(-1.3);脯氨酸(-1.6);组氨酸(-3.2);谷氨酸(-3.5);谷氨酰胺(-3.5);天冬氨酸(-3.5);天门冬酰胺(-3.5);赖氨酸(-3.9);精氨酸(-4.5)。
据信,氨基酸的相对亲水性特征确定所得多肽的二级结构,其反过来限定多肽与其他分子(例如酶、底物、受体、抗体、抗原等)的相互作用。本领域中已知氨基酸可由具有类似亲水性指数的另一种氨基酸取代,而又仍然获得功能等价的多肽。在这种改变中,亲水性指数在±2内的氨基酸的取代是优选的,在±1内的那些是特别优选的,在±0.5内的那些是甚至更特别优选的。
还可基于亲水性进行类似氨基酸的取代,特别是在如此产生的生物功能等价的多肽或肽旨在用于免疫实施例时。氨基酸残基被赋予了以下亲水性值:精氨酸(+3.0);赖氨酸(+3.0);天冬氨酸(+3.0±1);谷氨酸(+3.0±1);丝氨酸(+0.3);天门冬酰胺(+0.2);谷氨酰胺(+0.2);甘氨酸(0);脯氨酸(-0.5±1);苏氨酸(-0.4);丙氨酸(-0.5);组氨酸(-0.5);半胱氨酸(-1.0);蛋氨酸(-1.3);缬氨酸(-1.5);亮氨酸(-1.8);异亮氨酸(-1.8);酪氨酸(-2.3);苯丙氨酸(-2.5);色氨酸(-3.4)。应理解一种氨基酸可取代具有类似亲水性值的另一种氨基酸,而又仍然获得生物等价的多肽,特别是免疫等价的多肽。在这种改变中,其亲水性值在±2内的氨基酸的取代是优选的,在±1内的那些是特别优选的,在±0.5内的那些是甚至更特别优选的。
如以上所列出的,氨基酸取代通常基于氨基酸侧链取代基的相对相似性,例如其疏水性、亲水性、电荷、尺寸等。将一种或多种以上特征考虑在内的示范性取代对于本领域技术人员而言是熟知的,并且包括(但不限于)(原始残基:示范性取代):(Ala:GIy、Ser)、(Arg:Lys)、(Asn:GIn1His)、(Asp:GIu、Cys、Ser)、(GIn:Asn)、(GIu:Asp)、(GIy:Ala)、(His:Asn、GIn)、(Ile:Leu、Val)、(Leu:Ile、Val)、(Lys:Arg)、(Met:Leu、Tyr)、(Ser:Thr)、(Thr:Ser)、(Trp:Tyr)、(Tyr:Trp、Phe)、以及(Val:Lle、Leu)。因此本公开的实施例考虑如上多肽的功能或生物等价物。特别地,多肽的实施例可包括与目标多肽具有约50%、60%、70%、80%、90%、以及95%的序列同一性的变体。
在本文中,两个氨基酸序列之间或者两个核酸序列之间的同源性通过参数“同一性”表达(同样参见以上)。序列的比对和同源性分值的计算可使用可用来进行蛋白比对和DNA比对的完全Smith-Waterman比对进行。分别使用缺省得分矩阵BLOSUM50和同一性矩阵来进行蛋白和DNA的比对。空位中第一个残基的罚分对于蛋白为-12,对于DNA为-16,而空位中另外的残基的罚分对于蛋白为-2,对于DNA为-4。比对可使用v20u6版FASTA包进行。
可使用“ClustalW”进行蛋白序列的多重比对。可使用蛋白比对作为模板进行DNA序列的多重比对,将氨基酸替代为DNA序列相应的密码子。
可替代地,可以使用不同软件来比对氨基酸序列和DNA序列。两个氨基酸序列的比对使用(例如)2.8.0版的EMBOSS包的Needle程序(http://emboss.org)确定。Needle程序执行中的全局比对算法描述于。所使用的取代矩阵为BLOSUM62,空位开放罚分为10,空位延伸罚分为0.5。
一个氨基酸序列(例如SEQ ID NO:1)与不同氨基酸序列(例如SEQ ID NO:2)之间的同一性程度计算为两个序列的比对中准确匹配的数量除以“SEQ ID NO:1”的长度或者“SEQ ID NO:2”的长度中最短的长度。结果表达为同一性百分比。关于比对和同一性参见以上。
准确匹配在两个序列在重叠的相同位置中具有相同的氨基酸残基时发生。
如果相关,两个核苷酸序列之间的同一性程度可通过Wilbur-Lipman方法使用LASER-GENETMMEGALIGNTM软件(DNASTAR,Inc.,威斯康辛州麦迪逊)使用同一性表和以下多重比对参数来确定:空位罚分10,空位长度罚分10。双序列对比参数为Ktuple=3,空位罚分=3,窗口=20。
某一多肽的氨基酸序列与SEQ ID NO:1的氨基酸的同一性的百分比可通过以下确定:i)使用Needle程序使用BLOSUM62取代矩阵、空位开放罚分10和空位延伸罚分0.5比对两个氨基酸序列;ii)对比对中准确匹配的数量进行计数;iii)将准确匹配的数量除以两个氨基酸序列中的最短序列的长度,iv)将iii)的相除结果转化为百分比。与本发明其他序列的同一性的百分比以类似的方式计算。
以示例的方式,一个多肽序列可与参考序列相同,即100%相同,或者它可包括与参考序列相比高达某一整数数量的氨基酸改变,以便%同一性小于100%。这种改变选自:至少一个氨基酸缺失、取代(包括保守的和非保守的取代)或插入,并且其中改变可在参考多肽序列的氨基-端或羧基-端位置或者那些末端位置之间的任何位置(其单独地散布于参考序列中的氨基酸中或者散布于参考序列中的一个或多个相邻基团中)发生。
保守的氨基酸变体还可包含非天然存在的氨基酸残基。非天然存在的氨基酸非限制性地包括反式-3-甲基脯氨酸、2,4-甲醇基脯氨酸、顺式-4-羟基脯氨酸、反式-4-羟基脯氨酸、N-甲基-甘氨酸、别苏氨酸、甲基苏氨酸、羟基-乙基半胱氨酸、羟基乙基高半胱氨酸、硝基-谷氨酰胺、高谷氨酰胺、哌可酸、噻唑烷羧酸、脱氢脯氨酸、3-甲基脯氨酸和4-甲基脯氨酸、3,3-二甲基脯氨酸、叔亮氨酸、正缬氨酸、2-氮杂苯基-丙氨酸、3-氮杂苯丙氨酸、4-氮杂苯丙氨酸、以及4-氟苯丙氨酸。将非天然存在的氨基酸残基引入蛋白中的几种方法在本领域中是已知的。例如,可采用其中使用化学氨酰基化的抑制物tRNA抑制无义突变的体外系统。用来合成氨基酸和氨酰基化tRNA的方法在本领域中是已知的。含有无义突变的质粒的转录和翻译在包含大肠杆菌(E.coli)S30提取物以及可商购的酶和其他试剂的无细胞系统中进行。蛋白通过色谱法纯化。在第二种方法中,在爪蟾卵母细胞中通过显微注射突变mRNA和化学氨酰基化的抑制物tRNA进行翻译。在第三种方法中,在不存在待替代天然氨基酸(例如苯丙氨酸)而存在期望的非天然存在的氨基酸(例如2-氮杂苯丙氨酸、3-氮杂苯丙氨酸、4-氮杂苯丙氨酸或4-氟苯丙氨酸)的情况下培养大肠杆菌细胞。非天然存在的氨基酸被引入蛋白中替代其天然的对应物。天然存在的氨基酸残基可通过体外化学修饰转化为非天然存在的氨基酸残基。化学修饰可与定点诱变结合,以进一步延伸取代范围。提供足以支持A1M的抗氧化特性的三维结构的可替代化学结构可通过其他技术(例如人造支架、氨基酸取代等)提供。另外,模仿如上的A1M活性位点的结构被设想具有与A1M相同的治疗功能或生理功能。

图3.III期变体的产率、纯度和聚集。
A.对纯化的所有III期A1M变体的产率进行对比。所有变体均得到良好产率,未标记的wt-A1M的产率稍低。B.通过在SDS-PAGE上分离10μg的所有变体对纯度进行研究。使用Bio-Rad的Image软件通过将主要单体条带与所有条带的光密度进行分析确定纯度。所有组氨酸标记的变体均显示出很高的纯度,而未标记的变体的密度则稍低(约90%)。C.通过非变性PAGE分离20μg的每种变体从而对大聚集物的存在进行分析。通过光密度分析法确定主要单体条带的强度和保留在施加细缝中的材料(聚集非常大)。大部分变体显示出少量的大聚集物,除了M8H-wt-A1M和未标记的变体,其显示稍高的百分比。所有变体均通过图片A给出的数字进行编码。
图4.各种缓冲液中100μM和1mM的III期变体溶液的聚集分析。
通过非变性PAGE分析对在不同缓冲液中从100μM浓缩到1mM之后的聚集倾向性进行研究。在每条泳道中分离20μg蛋白。使用单独条带强度的光密度分析法分析计算大聚集物的百分比。
A.所有变体均在pH 8.0或7.4的Tris-缓冲液中从100μM浓缩到1mM并通过PAGE进行分离。M8H4DK-wt、R66H+N1796D、M41K、R66H、N1796D分别标记为60、35、37、38和39,M8H-wt和M8H-R66H+N1796D标记为40和41,未标记的wt和R66H+N1796D标记为61和42。
B.各变体在pH 8.0和7.4的TRIS-缓冲液中和pH 7.4的PBS中浓缩到1mM,进行一次冻融循环,然后通过PAGE分离,并如进行分析。

B.通过410与420nm之间的吸收峰的出现和该峰的红移的幅度对血红素与A1M变体的结合进行分析(Karnaukhova等人,2014;Rutardottir等人,2016)。一式两份将44μM的蛋白溶液与40μM的血红素混合,并在室温下孵育2小时。通过270与450nm之间的波长扫描对各混合物进行分析。计算最高峰的位置和413:386的比例。所有的M8H4DK-变体均具有与wt-A1M大致相同的红移和比例,而M8H标记的变体则具有显著更高的比例。未标记的变体缺乏红移活性,从而证实之前的结果(Karnaukhova等人,2014)。
C.A1M与血红素琼脂糖的结合。通过将稀释系列的A1M或者对照卵白蛋白与血红素-琼脂糖或对照琼脂糖混合对A1M的特异性结合进行分析。该分析一式两份进行。使用BCA对原料以及血红素-琼脂糖和对照琼脂糖孵育物的流过液的蛋白定量进行测定。可从这些数据确定每个样品与血红素琼脂糖特异性结合的蛋白的量。结合蛋白相对于添加的蛋白作图,所有变体均观察到线性相关。通过线性回归计算线的斜率,并显示各份之间的平均值。在该方法中,所有变体均以大致相同的程度与血红素结合。

A1M变体表达克隆在完全NYAT(15mM的(NH4)2SO4,84mM的K2HPO4,23mM的NaH2PO4xH2O,2.2mM的柠檬酸氢二铵,1%(w/v)的葡萄糖,2mM的MgSO4,9μM的CaCl2x2H2O,85μM的FeCl3x6H2O,1.3μM的ZnSO4x7H2O,1.3μM的CuSO4x5H2O,1.8μM的MnSO4xH2O,1.5μM的CoCl2x6H2O,108μM的EDTA,50μg/ml的卡那霉素)中生长到OD600为1.5。然后通过添加1mM的IPTG诱导蛋白的表达。产生进行4小时。在诱导之前以及诱导1小时、2小时、3小时和4小时之后取样进行SDS-PAGE分析。
纯化
来自培养物的细菌通过在5000rpm下离心分离收集15分钟。细菌沉淀通过5次冻融循环裂解,在pH 8.0的20mM的Tris-HCl中稀释3次,并进行超声处理。包涵体(IB)通过在6000rpm下离心分离收集30分钟,并通过3次更多循环的再悬浮和离心分离进行洗涤。为了进行提取,将IB再悬浮于6M的盐酸胍、pH 8.0的20mM的Tris-HCl(6M的Gu-HCl)中,并在+4℃下搅拌孵育过夜。通过在26000g下高速离心分离将提取物澄清60分钟。保存上清液以便进行进一步的澄清,同时将沉淀进行另一循环的提取。将提取物的上清液合并,并通过深度过滤器过滤(置于KS50P过滤器顶部的K700P过滤器,PallCorp.,美国)进一步澄清。澄清后的提取物中的A1M使用Ni-琼脂糖树脂(Sigma-Aldrich,美国)纯化。简而言之,将树脂装填到10-ml一次性色谱柱(Bio-Rad,美国)中,并用6M的Gu-HCl平衡。使用所收集的自由流液和流通液将A1M提取物上样到柱上。该柱用5倍柱体积的6M的Gu-HCl洗涤,然后用4倍体积的6M的Gu-HCl+0.5M的咪唑洗脱。原料、流通液和洗脱的级分使用乙醇沉淀,溶解在1xSDS-PAGE加载缓冲液中,并通过SDS-PAGE分离。如果流通液含有显著量的A1M,那么就重复该纯化程序。提取物的蛋白含量通过280nm下的吸光度确定。
将Ni-琼脂糖洗脱液稀释到A280大约为5.0,并在重折叠之前冷却到+4℃。然后将洗脱液与2/3体积的pH 9.5的20mM的Tris-HCl+0.1M的NaCl中0.275M的L-半胱氨酸混合。然后迅速添加16.7倍体积的重折叠缓冲液。最终的缓冲液浓度为:(0.2mg/ml A1M,0.1M的Tris,0.6M的NaCl,0.45M的L-精氨酸,2mM的EDTA,10mM的L-半胱氨酸和1mM的L-半胱氨酸,pH9.5)。然后在+4℃下将该混合物搅拌1小时,并使用Centricon plus 70,10KUltrafiltration Devices(Merck Millipore;美国)将溶液浓缩到A1M溶液的初始体积。浓缩之后,使用同样的装置通过10次连续的2.5x稀释/浓缩循环将A1M溶液渗滤到pH 8.0的20mM的Tris-HCl中。渗滤之后,通过在15000g下离心分离将该溶液澄清15分钟,然后通过0.2μm的过滤器。
立即将重折叠的A1M施加到5ml Bio-Scale Mini UNOsphere Q Cartridge(Bio-Rad),用pH 8.0的20mM的Tris-HCl平衡。根据Bio-Rad针对盒的说明将柱在纯化器10仪器(GE Healthcare,美国)上运行。将样品上样之后,将柱用5倍柱体积(CV)的pH 8.0的20mM的Tris-HCl洗涤,然后用20倍CV的从0M的NaCl到0.35M的NaCl的线性梯度洗脱。最后,将柱用3倍CV的1M的NaCl洗涤。在线性梯度过程中收集的流通液和所选级分通过SDS-PAGE进行分析。立即将具有剩余的A1M的流通液在新的柱上再次运行,并将含A1M的级分合并,浓缩到100μM,无菌过滤,并在-20℃下等份冷冻。
凝胶电泳
SDS-PAGE根据Laemmli(Laemmli,1970)使用标准方案运行。蛋白在300V下在无染色的4-20%TGX凝胶(Bio-Rad)上分离17分钟。非变性PAGE在无SDS并且无染色的4-20%TGX凝胶上无还原剂的情况下在200V下运行40分钟。在Chemidoc MP仪器(Bio-Rad)上对凝胶进行分析。
圆二色性
在2-mm小池中pH 8.0的20mM的Tris-HCl+0.15M的NaCl中10μM的溶液的Jasco-J180荧光分光计仪器(JASCOInc.,日本)上记录圆二色性光谱。溶液在+22℃下在190nm与260nm之间扫描。将每个样品三次运行的结果重叠。使用http://k2d3.ogic.ca软件计算α螺旋和β折叠结构的百分比。
SEC-FPLC
在纯化器10仪器上使用24-ml Superose 12 10/30 GL柱(GEHealthcare)通过尺寸排除对蛋白进行分析。使用1ml/min的流速将柱用pH 8.0的20mM的Tris-HCl+0.15M的NaCl平衡。以100μl的体积将100-200μg蛋白上样到柱上,并使用0.75ml/min的流速使用pH 8.0的20mM的Tris-HCl+0.15M的NaCl洗脱。通常,单体A1M在15ml/20分钟之后被洗脱,二聚A1M在13-14ml/18-19分钟之后被洗脱,大聚集物在8ml/12分钟之后被洗脱。大聚集物的百分比由8-ml峰下的面积与总的峰面积的对比来计算。压力处理(参见以下)之后从柱上收回的总蛋白的百分比通过将经处理样品的总的峰面积与未处理样品的总的峰面积对比来计算。
RP-HPLC
在Agilent 1260Infinity Binary LC系统上使用Aeris Wildpore 3.6μM的XP-C8柱(Phenomenex Inc.,美国)运行反相HPLC。该柱在+25℃下使用1ml/min的流速运行,并使用70%H2O+0.1%TFA和30%乙腈+0.1%TFA的混合物平衡。上样10μl(=10μg蛋白),并在20分钟内使用30-50%的乙腈的线性梯度洗脱。通过使用95%的乙腈洗涤10分钟将柱再生。
动态光散射
未受应激(stress)的样品和受到剪切应激的样品的动态光散射(DLS)分析使用SARomics Biostructure AB,Lund的服务进行。在+20℃下在Malvern APS仪器上对pH 8.0的10mM的Tris-HCl+0.125M的NaCl中稀释为10μM的A1M样品进行分析。各样品一式两份制备,每个样品检查3次。
差示扫描荧光测定法
使用SARomics Biostructure AB,Lund的服务通过差示扫描荧光测定法(DSF)对A1M变体的热稳定性进行分析。将pH 8.0的10mM的HEPES+0.125M的NaCl中稀释为4.4μM的A1M与SYPRO Orange混合(总共1000x的SYPRO Orange稀释)。分析一式两份进行,并计算平均熔融温度(Tm)。
通过剪切力引入应激
使用0-10μl吸液头通过多通道吸液管吸液80次将10μl的100-μM的A1M溶液暴露于剪切力应激。应激处理一式多份进行。吸液之后,将各份合并,并稀释10倍,然后如使用DLS进行分析。
高浓度-引起的应激
在高浓度下分析A1M的溶解性和稳定性。使用Amicon Ultra-0.5,10K Devices(Merck Millipore)通过在14000g下离心分离10分钟将500μl的100μM的A1M溶液浓缩10倍到50μl。浓缩之后,使用相应的流通液将体积校正到恰好50μl。在非变性PAGE上对浓缩的样品和未浓缩的样品(10μg)进行并排对比。在浓缩之前通过将样品渗滤检查不同缓冲液的影响。这通过在Amicon Ultra-15,10K Devices中5个循环的10倍稀释/浓缩来进行。
游离硫醇的定量
A1M变体的游离硫醇使用Molecular Probes的“硫醇和硫化物的定量试剂盒”确定。该分析在96孔板中根据试剂盒手册进行。将某一体积的3μl标准物或A1M(100μM)与3μl胱胺工作溶液(worksolution)、100μl木瓜蛋白酶-SSCH、100μl L-BAPNA混合。该分析读取为405nm下的吸光度。
ABTS还原分析
该分析是(等人2007)的改写。7mM的2,2连氮基-双(3-乙基苯并噻唑啉-6-磺酸)二铵盐(Sigma-Aldrich)用2.45mM的K2S2O8过夜氧化,然后在pH 8.0的25mM的磷酸钠缓冲液中稀释到56μM。向96孔板的每孔中添加100μl的ABTS工作溶液。使用PerkinElmer Plate Reader在A405下进行零时间点测量。通过多通道吸液管迅速添加2μl的A1M溶液(0-100μM)。迅速追踪405nm下吸光度降低的动力学,进行95秒。为了切实可行,这时只分析8个孔。A1M稀释系列一式两份或者一式三份进行。如果待分析样品的数量需要几个板来进行,那就将新的ABTS储备稀释成用于每个板的工作储备,并在所有板中包括wt-A1M参考样品。每个浓度的吸光度相对于时间作图,计算每个浓度曲线下的面积(AUC)。通过扣除单独的缓冲液的AUC计算净AUC。
氧自由基抗氧化能力(ORAC)分析
商用试剂盒OxySelectTM Oxygen Radical Antioxidant Capacity(ORAC)活性分析(CellBiolabs,Inc。美国)基于过氧基自由基对荧光探针的氧化和破坏。当存在抗氧化剂时,该破坏就会受到抑制。作为标准物,使用水溶性的维他命E衍生物Trolox。按照试剂盒手册进行操作、分析和计算,2.5-5μM的A1M浓度很好地拟合到标准曲线。卵白蛋白(Sigma-Aldrich)用作阴性蛋白对照。
细胞色素c的还原分析
该分析是(Allhorn等人2005)的改写。通过将100μM的细胞色素c(Sigma-Aldrich)与100μM的NADH在pH 8.0的10mM的Tris-HCl+0.125M的NaCl中混合制备工作溶液。一式两份向96孔板中添加11μl的A1M溶液(0-100μM)。使用多通道吸液管迅速向每孔中添加100μl的细胞色素c工作溶液。追踪550nm下吸光度增加的动力学,进行20分钟。这时分析一个板。未能观察到时间偏差。如果要分析几个板,那么全部使用同样的工作溶液,该程序不会导致任何可观察到的人为缺陷。测量之后,如ABTS分析对各结果进行分析。
红移分析
将游离血红素结合到A1M中会产生Soret条带吸收峰的红移(Karnaukhova等人,2014;Rutardottir等人,2016),并在A1M-突变体中评估为A413/A386比。将pH 8.0的20mM的Tris-HCl+0.25M的NaCl中44μM的A1M与40μM的游离血红素(Applichem)混合。孵育一式两份进行,并在室温下孵育2小时。通过在Beckman分光光度计中进行波长扫描在稀释4倍的样品中对红移进行分析。计算各份的平均最高峰以及413与386nm下的吸光度的平均比例。卵白蛋白和单独的缓冲液用作阴性对照。
A1M与血红素-琼脂糖的特异性结合
通过如改善(Rutardottir等人,2016)的(Larsson等人,2004)的方法对A1M与血红素-琼脂糖的结合进行分析。血红素-琼脂糖(Sigma-Aldrich)和对照Sepharose 4B(Sigma-Aldrich)用pH 8.0的20mM的Tris-HCl+0.25M的NaCl平衡,并制备为50%的浆液。将75μl的A1M稀释系列(0-13.3μM)添加到两个96孔板中(一个板用于血红素琼脂糖,一个用于对照Sepharose)。通过小心吸液以确保转移类似的量将20μl的血红素-琼脂糖och对照Sepharose浆液添加到各孔中,并在旋转搅拌过程中在室温下孵育30分钟。将该混合物小心转移到AcroPrep Advance 96孔过滤板-1.2μm Supor Membrane(Pall Corp)中。在1000g下将各板离心2分钟,从而将流通液收集到低结合微板中。使用Pierce BCA Protein Assay试剂盒(Thermo Scientific Inc.,美国)分析25μl的每个流通液以及未孵育的原料的蛋白含量。对于血红素-孵育的样品和对照Sepharose孵育的样品将蛋白的量重新计算为结合的量(流通液中增加的减少的量(added minus amount))。扣除与对照Sepharose结合的量之后,与血红素琼脂糖特异性结合的量相对于增加的量作图。通过线性回归计算曲线的斜率。使用各份的标准偏差来评估各A1M变体之间的差异显著性。
M8H4DK-wt A1M(Wt-A1M)和M8H4DK-35-A1M(35-A1M)的血红素结合
如前所描述的,通过非变性PAGE(Karnaukhova等人,2014)和UV-分光光度法(Ruttarsdottir等人,2016)对血红素结合进行分析。简而言之,对于非变性PAGE,A1M和各种浓度的血红素在室温下在pH 8.0的Tris-缓冲液中孵育30分钟,通过非变性PAGE在200V下在无染色的12%Criterion TGX凝胶上分离40分钟。各凝胶条带在用于色氨酸荧光的Chemidoc MP仪器(Bio-Rad)上使用无染色设置进行分析,使用Coommassie BrilliantBlue染色,脱色,并再次使用Coommassie设置在Chemidoc上成像。然后使用Image LabTMSoftware(Bio-Rad)对两组条带进行定量。然后将血红素结合估算为Coommassie染色之后相对于总蛋白量淬灭色氨酸荧光的量。在22℃下在Beckman(Beckman Instruments,加利福尼亚州富勒顿)DU800分光光度计上使用600nm/min的扫描速率在250nm与700nm之间的UV-VIS区对吸收光谱进行测量。A1M和血红素的浓度分别为32μM和19μM,在pH 8.0的20mM的Tris-HCl、0.15M的NaCl中。从DMSO中10mM的储备溶液添加血红素。混合2小时之后对蛋白溶液进行扫描。

A1M变体构建体的基本原理(Rationale)
在I期中对人wt-A1M、来自各种物种的11种A1M-同源物以及15种具有点突变的A1M变体进行构件、表达、纯化和分析,即总共27种A1M变体(表2)。11种A1M-同源物如下选择。A1M在各物种之间保守性良好。不同物种的A1M序列在数据库(www.ncbi.nlm.nih.gov和www.uniprot.org)中进行搜索。找到67种不同物种的AMBP序列。对各序列研究A1M-特异性的官能团(K69、K92、K118、K130、Y22;Y132、H122和H123)、脂质运载蛋白基序(SCR1、2、3)(参见介绍中的参考)和预测的碳水化合物结合位点(Escribano等人,1990)的存在。5种被分类为非-A1M,并且由于它们缺乏半胱氨酸34而被放弃,3种由于它们缺乏半胱氨酸169而被放弃,4种由于它们不完整而被放弃,2种由于它们具有长的有问题的插入而被放弃。将剩余的53种同源物的氨基酸序列比对,并且通过将其氨基酸序列投射到人A1M的晶体结构上来模拟它们建议的3D结构(Meining和Skerra,2012),以确定单独的氨基酸侧链在脂质运载蛋白环中的位置或者在口袋内部或外部上的位置。它的结果如下用来构件影响A1M-功能的点突变。用来选择最后11种同源物(参见表2)的基本原理是广泛的进化表现、方法可能性、物种的生活栖息地中可能增加的环境氧化应激、A1M-特异性官能团的存在或者缺乏、以及糖基化的缺乏的组合。如下选择了15种具有点突变的A1M变体。8种变体针对功能特性在关键氨基酸处突变,7种变体在暴露的位置突变,以改善稳定性/溶解性(表2)。之所以选择8种功能突变是由于它们1)在其他物种中发生在3D-结构模型中可能会影响A1M的功能的位置(参见以上)并且/或者2)理论上会降低半胱氨酸34的pKa并且/或者3)理论上会提供额外的自由基捕获位点。对于所有变体预测的数据使用http://www.αlyse.com/gpmaw_lite.html工具来计算(表3)。
表3.预测的I期变体数据
I期
变体在平行的摇瓶中表达。表达水平有所变化,对于几种A1M变体表达必须重复几次,以获得合理的蛋白量。对于小鼠、松鼠猴、海象、猩猩、M41K、R66H、T75Y、M99K、N17,96D、T45K和V148D在纯化之后获得良好的表达和较大的量(>10mg/L培养物)。纯化的蛋白的表达和量与之前在类似条件下表达和纯化的人wt A1M的产率(12mg/L)类似。具有更低表达水平并产生更低产率(1-10mg/L)的变体是裸鼹鼠、青蛙、兔、海牛、P35K、T75K、S101Y、L89T、V170S和G172Q。鸡、比目鱼和空棘鱼的A1M显示出次优的表达水平,从而得到纯化产率<1mg/L培养物。四重人突变体K69,92,118,130R表达地很好,但是不可能成功地再折叠。T75K-A1M在纯化过程中也显示出增加的沉淀倾向性。
根据SDS-PAGE所有变体均被纯化到>99%的纯度,除了鸡和空棘鱼的A1M,其被纯化到95%的纯度。根据SDS-PAGE,所有变体均含有最多0.5%的共价二聚体,各变体之间没有主要差别。圆二色性显示所有变体均具有约2%的α螺旋结构和40%的β折叠结构而没有主要差别,这是A1M的预期值(Kwasek等人,2007)。纯化之后,所有变体如表4所概括进行分析。首先对稳定性和溶解性进行分析。通过动态光散射(DLS)、PAGE(聚集)和差示扫描荧光测定法(DSF)(热稳定性)对新融化的未受应激的0.1mM的蛋白溶液的聚集倾向性和热稳定性进行分析。另外,对响应于剪切力或者浓缩到1mM而聚集的倾向性进行了研究。人wt A1M在这些分析中表现得较好(表4),但是一些变体在稳定性/溶解性特性方面甚至表现得更好:鸡A1M、海牛A1M和N17,96D-A1M。鸡A1M和海牛A1M在太多的位置与人wt A1M不同,以至于不能够设想对于人A1M有益的单独氨基酸,并且未用于进一步的研究。当研究功能特性时,发现M41K和R66H具有相同(R66H)或者改善的(M41K)功能。由于这些变体还具有比大部分其他变体更高的热稳定性以及仅仅略微更高的聚集倾向性,因此选择它们进行进一步的研究。因此,N17,96D-A1M、M41K-A1M和R66H-A1M持续到项目II期。
II期
项目II期的目标是将有益的突变(M41K、R66H和N17,96D)结合,以便研究是否可以构建具有类似或改善的功能并且甚至更稳定的变体。另外,引入了相同的N端标记(M8H4DK),其用于人wt A1M(表5)。这样,新结合的M8H4DK-变体被与M8H4DK-人wt对比。
表5.II期中表达的变体以及预测的数据
所有四种新的变体(M8H4DK-M41K+R66H、M8H4DK-M41K+N17,96D、M8H4DK-R66H+N17,96D和M8H4DK-M41K+R66H+N17,96D)均非常好地表达,并获得29、13、37和15mg纯蛋白/L的产率。根据SDS-PAGE,四种新的变体被纯化到>99%的纯度,并且显示出相同或者更低的共价二聚体百分比,除了M8H4DK-M41K+R66H,其显示出大约2%的共价二聚体。
对增溶作用/稳定性特性进行了分析(表6a)。数据显示,M41K与R66H的组合对于热稳定性是次优的。另一方面,N17,96D突变对于增溶作用和稳定性通常是有益的,并且与R66H的组合(即M8H4DK-R66H+N17,96D-A1M)产生甚至更佳的增溶作用和稳定性。
对功能特性进行了分析(表6b)。数据显示,M41K突变具有增加的血红素还原能力,但是血红素结合降低。但是,当M41K突变与N17,96D组合时,它显示出更低的保护细胞免于血红素引起的细胞死亡的潜力。R66H+N17,96D的组合与wt-A1M相比在所研究的全部功能方面均产生类似的结果。因此,M8H4DK标记的R66H+N17,96DA1M是II期之后一个有前景的候选物,而M41K-突变则没那么有用。
III期
III期的第一个目标是在在相同条件下平行表达时将M8H4DK标记的R66H+N17,96D-A1M与wt-A1M以及I期和II期有前景的M8H4DK标记的单个突变进行对比。第二个目标是研究标记对稳定性、溶解性和功能的影响。人wt A1M的N端标记(M8H4DK)包括8个组氨酸的标记,接着是一个肠激酶切割位点。切割位点使得能够在表达和纯化之后切割组氨酸标记。因此,wt-A1M和R66H+N17,96D-A1M在表达后具有N端的M8H4DK-标记和M8H-标记,也可能没有标记。第三个目标是更详细地将M8H4DK-wt A1M(Wt-A1M)的特性与M8H4DK-R66H+N17,96D-A1M(35-A1M)的特性进行对比。III期所有表达的变体以及预测的数据在表7中示出。

平行表达和纯化容许对表达水平和纯化产率进行更精确的对比。发现所有表达A1M变体的细菌均以相同的速率(未显示)和相同的较好产率生长(图2)。仅有的差别是未标记的变体(#60和#42)与其他变体相比表达更慢。从2x750ml表达物能够纯化20-60mg的每种变体(图3a)。所有组氨酸标记的变体均被纯化到>99%的纯度,而未标记的变体(#61和#42)则显示出略微更低的纯度(约90%)(图3b)。全部都显示出少量的共价二聚体。PAGE分析显示所有变体均具有小于1-2%的大聚集物,除了M8H-wt(40)和未标记的wt-A1M(#61)(图3c)。因此,所有单独的和多种M8H4DK标记的、M8H标记的和未标记的A1M变体都能够产生。
通过反相HPLC、动态光散射和差示扫描荧光测定法对100μM的溶液的聚集和热稳定性进行了分析(表8)。在RP-HPLC中,M8H4DK标记的变体在大约12分钟被洗脱,主峰中具有87-90%的蛋白。唯一的例外是M8H4DK-M41K,它出现在9.8分钟的保留时间处,并且主峰中只有80%的蛋白。该数据再一次表明,M41K突变产生出乎意料的A1M蛋白特性,是次优的。将标记变为M8H或者完全去除标记分别导致保留时间增加到12.2分钟和12.9分钟,表明是疏水性更高的分子,这正是所预料的。对于M8H-wt和两种未标记的变体,主峰中存在更少的蛋白,可能反映这些变体的SDS-PAGE中观察到的略微更低的纯度。DLS-数据显示,所有变体的平均半径约为3,并且可以从所有6个记录收集数据。所有变体均具有与M8H4DK-wt A1M相同或者更高的热稳定性。带有N17,96D突变的所有变体均观察到更高的稳定性。
表8.非应激的III期变体的聚集和热稳定性。
通过在窄吸液头中吸液80次将III期的变体暴露于剪切力。使用DLS对剪切应激引起的聚集进行分析。一般而言,具有N1796D突变的所有变体对剪切应激均显示出高的耐受性(表9),除了M8H标记的R66H+N1796D变体(#41)。另外,研究了对在不同缓冲液中浓缩到1mM引起的应激的耐受性。所有变体均在pH 8.0或7.4的20mM的Tris-HCl+0.125M的NaCl中浓缩到1mM,并立即通过PAGE进行分析(图4a,表10)。还在Tris-缓冲液或PBS中进行单次冻融循环之后通过PAGE对0.1mM和1mM的样品进行了分析(图4b,表10)。在M8H4DK标记的变体中,所有带有N17,96D的突变与wt A1M相比对浓缩、冻融、pH降低和缓冲液改变(变为PBS)均显示出增加的耐受性。添加R66H突变甚至进一步改善了稳定性和溶解性。单独的R66H突变具有与wt A1M大致相同的耐受性,而M41K突变则具有显著更低的耐受性。N端标记的缩短或去除对耐受性具有负面作用,与相应的R66H+N17,96D变体相比对于wt A1M的负面作用更显著。
表9.III期变体的剪切稳定性。
在延伸项目中研究了所有III期变体的功能活性以涵盖已知A1M功能的所有可能方面。在合成ABTS自由基上并在可商购的氧自由基抗氧化能力(ORAC)分析中研究了与血红素不相关的还原能力(图5)。M8H4DK标记的N17,96D-A1M和R66H+N17,96D-A1M显示出与wtA1M类似的还原能力,而M8H4DK标记的M41K-A1M和R66H-A1M则显示出略微更低的ABTS还原能力(图5A)。标记的缩短或去除几乎没有作用,但是当被M8H-标记和未被标记时R66H-N17,96D变体则显示倾向于具有比wt A1M更高的还原能力。M8H4DK标记的wt A1M的性能在ORAC分析中被设定为100%,其他变体相对于其进行对比。所有的M8H4DK-变体在ORAC中均显示出与M8H4DK-wt相同的结果,除了M8H4DK-R66H+N17,96D,其具有显著更高的能力(图5b)。另外,M8H标记的和未标记的R66H+N17,96D-A1M显示出比wt-A1M略微更高的ORAC能力。还在细胞色素c的还原分析中对还原能力进行了研究(图6)。大部分变体与wt-A1M相比在更低的浓度下显示出略微更低的还原能力,并且对于N17,96D和R66H+N17,96D而言,这是显著的(在0.3-0.6μM下)(图6A)。它的重要性尚不清楚。标记的缩短和去除对该特性无影响。
在游离血红素结合分析和血红素-琼脂糖结合分析中研究了血红素结合(图6)。随着在约410-415nm处出现吸收峰(所谓的Soret条带)观察到游离血红素的结合和配位(Karnaukhova等人,2014;Rutardottir等人,2016)。血红素通常在约380-390nm处具有吸收峰,并且这可在它单独溶解时或者在它与像卵白蛋白这样的非结合性对照蛋白一起混合和孵育时被观察到。但是,当血红素与wt A1M混合时,在410nm与415nm之间形成吸收峰,产生所谓的红移(即峰向更高的波长移动)和增加的Abs(413/386)比例。据显示红移程度和Abs(413/386)比例与A1M的血红素-结合功能相关(Rutardottir等人,2016)。因此在III期中对于所有变体将这些特性进行对比(图6b)。在M8H4DK标记的变体中,全部都显示出与wt A1M大致相同的红移,除了M41K变体,其具有更强的移动。有趣的是,将标记缩短为M8H增加了红移,而去除标记则降低了红移。显然,标记对该特性具有强烈的影响。将稀释系列的A1M与血红素-琼脂糖的结合跟与对照琼脂糖的结合对比,从而研究了血红素与A1M的结合。通常,像卵白蛋白这样的对照蛋白显示没有与血红素-琼脂糖的结合高于背景与对照琼脂糖的结合(图6C)。通常,所添加的M8H4DK-wt A1M(35-A1M)的70-80%与血红素琼脂糖结合,而与对照琼脂糖的结合则未观察到。在III期中将所有变体的结合进行对比。全部都显示出类似程度的与血红素-琼脂糖的结合(66-72%),而卵白蛋白则未显示结合。
使用迁移偏移和荧光分析的结合(Karnaukhova等人2014)进一步对血红素与M8H4DK-wt A1M(wt-A1M)和M8H4DK-35-A1M(35-A1M)的结合进行分析(图11)。作为血红素结合的结果,非变性PAGE分析中wt-A1M和35-A1M的迁移在血红素:蛋白比<1时更慢,在血红素:蛋白比>1时更快,显示对血红素浓度的相同依赖性(图11A和B)。在高血红素浓度下,两种变体显示倾向于低聚,从而支持之前对于wt-A1M的发现(Karanaukhova等人2014)。类似地,血红素结合以类似的动力学在两种wt-A1M和35-A1M中引起色氨酸荧光的淬灭(图11B)。以前显示血红素配位到A1M中引起415nm下UV-吸收峰的形成(Ruttarsdottir等人,2016;karnaukhova等人,2014)。观察到wt-A1M-和35-A1M/血红素络合物类似的UV-吸收模式(图11C),35-A1M峰仅有小的红移(415→417nm)。
使用未受应激的新制蛋白对wt-A1M和35-A1M的ABTS-自由基还原速率进行了研究[10],其对于wt-A1M和35-A1M类似(图12A)。在储存7天之后,wt-A1M在浓缩到1mM之后和在22℃下显示出更慢的还原速率(图12B),表明除了这些条件下显示的聚集之外还损失蛋白活性(表11)。细胞色素c-还原(Allhorn等人,2005)对于35-A1M略微更慢(图12C),而通过ORAC分析测量的抗氧化能力对于35-A1M则略微更高(图12D)。

对A1M变体保护K562细胞免于血红素引起的细胞死亡的能力进行研究的生物分析(图7)。根据乳酸脱氢酶的释放,在无A1M的情况下用血红素孵育的细胞的细胞死亡程度被设为100%。所有M8H4DK标记的变体,包括wt-A1M,在10μM下均显示出几乎100%的保护(图7),在各变体之间无显著差别。M8H标记的变体显示出几乎相同的保护潜力,而未标记的变体则观察到略微更低的潜力。
M8H4DK-wt A1M(35-A1M)和M8H4DK-35-A1M(wt-A1M)的细胞保护能力
在暴露于游离血红素和游离的铁的K562细胞和人肾脏近端小管上皮细胞系(HK-2)中对两种A1M变体的细胞保护特性进行了测试。图12显示,通过暴露于0.1mM的血红素的K562-细胞的胞质标志LDH的胞外释放测量,两种A1M变体完全抑制细胞的死亡。wt-A1M和35-A1M的剂量响应曲线几乎完全重叠,表明类似的细胞保护能力。
图14中显示HK-2细胞的保护。首先,由Fenton(会产生羟基自由基的游离的铁、抗坏血酸盐和过氧化氢的混合物)反应引起细胞的破坏。通过追踪重叠剂量响应曲线,通过WST-1分析测量的细胞存活率由两种A1M变体恢复(图14A)。血红素加氧酶-1(HO-1)(一种记录详尽的氧化应激响应的生物标志(Alam等人,1999))的上调被wt-A1M和35-A1M以类似的程度显著抑制(图14B)。还通过使用血红素孵育引起HK-2细胞的细胞破坏,并且可被两种A1M变体抑制(图14C和D)。再一次,使用两种血红素浓度,10μM和30μM,通过WST-1分析测量的细胞存活率以类似的程度被两种蛋白恢复(图14C)。HO-1和另一种细胞应激响应基因Hsp70的上调被两种A1M变体以类似的程度抑制(图14D)。
小鼠中M8H4DK-wt A1M(wt-A1M)和M8H4DK-35-1M(35-A1M)的体内分布
以前显示静脉内注射的A1M被迅速从血液清除,并且主要集中在大鼠和小鼠的肾脏和肝脏(Larsson等人,2001;Ahlstedt等人,2015)。我们对wt-A1M和35-A1M在血液中的清除速率和在器官中的分布进行了对比(图15)。在前60分钟期间观察到类似的更新速率,而35-A1M则在1小时之后被更快地清除。在10分钟和30分钟之后A1M在研究器官中的分布在两种蛋白之间未显示任何显著的差别。wt-A1M和35-A1M均主要存在于肾脏中,在心脏、肝脏、肺部、皮肤和脾脏中观察到更少的量,而在大脑中则观察到可忽略的量。
M8H4DK-wt A1M(wt-A1M)和M8H4DK-35-A1M(35-A1M)对肾脏的体内保护
以前,A1M已经在引起血红素相关的肾脏损伤和氧化应激相关的肾脏损伤的动物模型中显示出体内治疗效果(等人,2014;等人,2015;Sverrison等人,2014)。在此,我们在甘油注射横纹肌溶解症小鼠模型中研究了两种A1M变体的体内保护作用,在小鼠模型中由于肌肉断裂而产生急性肾脏损伤(AKI),并释放肌红蛋白、游离血红素、自由基和其他组织成分。甘油注射引起HO-1基因和Hsp70基因(细胞应激的两种生物标志)(图16A和16B)的巨大上调,并且大部分上调由于同时注射wt-A1M或35-A1M而被抑制。在施用的剂量下(7mg/kg动物重量)未观察到两种A1M变体之间的显著差别。
总之,III期中的研究显示,含N17,96D的A1M-突变显著增加了A1M分子的稳定性,在添加R66H突变后A1M分子被进一步改善。此外,M8H4DK标记的A1M变体比具有更短标记的变体或者没有标记的变体更稳定。因此,标记不仅充当纯化工具,而且还为A1M提供增加的稳定性和稳定性,并且不会对功能造成影响。M8H4DK-R66H+N1796D(35-A1M)分子显示相同或者更佳的功能特性,可能细胞色素c的还原除外。总之,稳定性/溶解性和功能研究表明,M8H4DK-R66H+N17,96D(35-A1M)与M8H4DK-wt A1M(wt-A1M)相比具有改善的分子特性,并且使用急性肾脏损伤的横纹肌溶解症甘油注射模型Wt-A1M和35-A1M均显示对肾脏的体内保护作用。
M8H4DK-R66H+N1796D相对于M8H4DK-wt的进一步的稳定性研究。
为了进一步将M8H4DK-R66H+N17,96D-A1M与wt-A1M进行对比,在进行冻融循环并在+4℃和室温下储存之后通过SEC-FPLC和ABTS还原分析对聚集和功能进行测试(图8)。wt-A1M和R66H+N17,96D-A1M的样品(100μM)均很好地耐受5x冻融循环。如前所示,在浓缩到1mM之后wt-A1M显示出比R66H+N17,96D-A1M更多的聚集,储存1周之后与储存过夜之后相比观察到类似的结果。增加的wt-A1M的聚集未影响2μM-样品的ABTS还原活性。在冻融、浓缩并在+4℃下储存1周之后,目视检查显示两个变体完全清澈的溶液。为了进一步使A1M溶液受到应激,将100μM和1mM的溶液在室温下储存1周。100μM的溶液的目视检查显示轻微的wt-A1M浑浊,但是R66H+N17,96D-A1M溶液则保持清澈。SEC-FPLC显示wt-A1M的曲线下面积降低到原料的80%,表明wt-A1M的损失,尽管未观察到大聚集物的增加。损失最可能是由于蛋白被沉淀并在运行FPLC之前通过过滤除去而引起。对于R66H+N17,96D-A1M,可观察到聚集的一些增加,但是在100μM下在室温下储存一周之后未损失蛋白。在ABTS分析中,R66H+N17,96D-A1M仍显示出完全活性,而对于wt-A1M则观察到稍微降低。储存1周的1mM的溶液的目视检查显示两种变体都浑浊,但是wt-A1M溶液看上去更稠。在溶液被稀释10倍以便上样到SEC上时,R66H+N17,96D-A1M的沉淀被溶解,但是wt-A1M的沉淀则未被溶解。在SEC中,观察到很少的聚集物,但是仅44%的wt-A1M原料保留。相比而言,R66H+N17,96D-A1M则100%保留。在ABTS分析中,wt-A1M具有严重降低的活性,而R66H+N17,96D-A1M的活性则保持不变。该研究显示,M8H4DK-R66H+N17,96D-A1M在室温下在高浓度下能够耐受储存,而wt-A1M则不能。
在37℃下研究了1mM的溶液的稳定性。将样品孵育1.5小时、2.5小时和4.5小时,然后进行目视检查,通过SEC-FPLC和ABTS还原分析进行分析(图9)。孵育1.5小时之后,在目视检查时两个溶液仍然是清澈的,但是SEC-FPLC显示在wt-A1M溶液(53%)中比在R66H+N17,96D-A1M溶液(28%)中具有更多的聚集物。通过曲线下的面积估计,在wt-A1M的SEC上仅67%的原料被洗脱,而R66H+N17,96D-A1M则100%被洗脱。两种变体在ABTS分析中均显示出完全活性。孵育2.5小时之后,wt-A1M溶液变浑浊,沉淀不能溶解。在SEC上发现40%的原料,ABTS活性被显著降低。R66H+N17,96D-A1M溶液仍然是清澈的,并在ABTS分析中显示出完全活性,但是大聚集物则在SEC-FPLC中从28%增加到38%。4.5小时之后,wt-A1M变为粘稠物质,不能进行吸液。因此,未进一步对其进行分析。R66H+N17,96D-A1M变浑浊,但仍不能进行吸液。一些沉淀在稀释之后仍然保留。SEC上洗脱的蛋白的量为原料的44%,并在ABTS分析中观察到降低的活性。研究表明,在+37℃下孵育之后,A1M首先形成可溶解的聚集物,然后它形成不可逆的聚集物,并在ABTS分析中损失活性。孵育2.5小时之后观察到完全不可逆的wt-A1M沉淀,而对于M8H4DK-R66H+N17,96D-A1M在4.5小时之后则仅观察到部分不可逆的沉淀。因此,M8H4DK-R66H+N17,96D-A1M在+37℃下比M8H4DK-wt-A1M更不能耐受储存。
