Abstract
本发明涉及D‑N‑氨甲酰水解酶及其在D‑色氨酸生产上的应用,所述水解酶具有如SEQ ID No.1所述的氨基酸序列。
Description
技术领域
本发明属于生物催化领域,具体涉及一种D-N-氨甲酰水解酶及其在D-色氨酸生产上的应用。
背景技术
D-色氨酸(D-Trp)是一种手性非常见氨基酸,在饲料行业和医药行业都有很大的市场和应用价值。在食品饲料工业中,D-色氨酸可以作为一种非营养甜味剂或饲料添加剂;在医药行业中,D-色氨酸主要被作为合成一些医药(如他达拉非)的中间体,或半合成肽类抗生素的原料;此外,D-色氨酸具有较高稳定性、广谱抗菌性、毒性小、过敏性低、吸收快、血浓度高、药力持续时间长等优势,是一种有低过敏性和抗药性的优点的非蛋白活性的氨基酸。因此D-色氨酸有很大的市场前景,需求量呈逐年增加的趋势。
目前,D-色氨酸的合成方法有拆分法、酶法合成和不对称合成法等。化学拆分法所用的拆分剂较贵,且具有步骤多、污染环境等问题;酶法拆分则在获得D-构型的同时分离(或消耗掉)一半L-构型;化学的不对称合成法步骤多、收率低、有机试剂容易污染环境;而酶法合成工艺简单、专一性强,条件温和且不污染环境,符合大规模工业化生产的要求。
当前酶法合成D-色氨酸的主要考虑路线是以L-吲哚甲基海因作为原料,使用海因消旋酶、D-海因酶和D-N-氨甲酰水解酶组成的三酶催化反应。一方面由于L-色氨酸的发酵生产已经成为成本较低的色氨酸骨架的主要来源,另一方面,该路线反应得率高,与其他方式相比具有较好的经济优势。
在L-吲哚甲基海因路线中,D-N-氨甲酰水解酶催化D-N-氨甲酰氨基酸水解得到产品D-氨基酸,它的立体选择性和催化速度是决定产物浓度和反应时间的主要因素。

V)吲哚甲基海因的合成是利用L-色氨酸和氰酸钾在酸性条件下反应,按照文献Journal of Labelled Compounds and Radiopharmaceuticals,54(2),110-114;2011所述方法制得。D-N-氨甲酰-色氨酸的合成是利用D-色氨酸和尿素在微波条件下反应制得(J.Med.Chem.2016,59,1580-1598)。
实施例1:分子克隆
如SEQ ID No.2所示的基因片段合成后,经NdeI-HindIII消化后,凝胶回收编码片段并与同样位点消化的pET-30a载体用T4连接酶连接。连接产物转化至大肠杆菌BL21(DE3)感受态细胞中,涂布于LB琼脂培养基(含有50mg/L的卡那霉素)、挑单菌落至LB液体培养基(含有50mg/L的卡那霉素)中培养,测序验证克隆正确性。经验证的克隆置于-80℃保藏备用。
实施例2:SEQ ID No.1编码的水解酶在大肠杆菌中的重组可溶表达。
在LB琼脂培养基上将保藏的克隆活化。然后将单菌落接种至LB液体培养基(含有50mg/L的卡那霉素)中,37℃震荡温育12h。将1mL培养物转接至50mL新鲜的LB液体培养基(含有50mg/L的卡那霉素)中,37℃震荡温育至OD600达到0.6左右,加入IPTG(终浓度为0.4mM)在25℃温育16h以诱导蛋白质表达。
温育后,将培养物以4,000g在4℃离心10min,弃上清,收集大肠杆菌细胞。将收集的大肠杆菌细胞重悬于预冷的15mL pH 7.0的磷酸盐缓冲液(PBS)中,在4℃超声破碎大肠杆菌细胞。细胞破碎液以6,000g在4℃离心15min去除沉淀,得到的上清为含重组酶的粗酶液。从对应的SDS-PAGE分析的结果看,水解酶(如图1箭头所指)在大肠杆菌宿主中是可溶表达的。
实施例3:SEQ ID No.1编码的水解酶对D-N-氨甲酰-色氨酸的水解实验
将D-N-氨甲酰-色氨酸溶解于100mM pH=7.5的磷酸盐缓冲液(PBS)中,使得最终反应体系溶液中D-N-氨甲酰-色氨酸的终浓度为3g/L。向上述溶液加入0.4%体积的摇瓶超声酶试剂样品。在35℃,于振荡器上持续震荡(800rpm)2小时,取样并用高效液相色谱检测底物的转化情况。经HPLC定量分析,产物D-色氨酸的浓度为1.1g/L;经手性柱分析,D-色氨酸产物的e.e.值>99.9%。与之对应的,空pET-28a质粒酶液对照中无D-色氨酸产物。
实施例4:SEQ ID No.1编码的水解酶在吲哚甲基海因酶法制备D-色氨酸的应用
在100mL三颈烧瓶进行反应制备D-色氨酸,终体积25mL的反应体系中,含30g/L终浓度L-吲哚甲基海因(750mg),NaHCO3终浓度2g/L,MnCl2终浓度0.5mM,PBS 50mM(pH 7.5),再依次加入下列pET-28a载体在BL21(DE3)宿主经摇瓶表达的超声裂解粗酶液,来自Agrobacterium tumefaciens的海因消旋酶(750uL,GenBank:QCM13411.1)、来自Agrobacterium tumefaciens的D-海因酶(1500uL,GenBank:WP_080866389.1),和SEQ IDNo.1编码的水解酶(2500uL)。反应在搅拌下维持35℃,滴加2M NaOH维持pH 7.5-8.0下进行,通过HPLC检测反应进程。经过夜反应后,反应体系中的微溶底物L-吲哚甲基海因全部消耗,溶液变成透明(底物消失),D-色氨酸终浓度为26.69g/L,产率99.8%。
具体数据如表1.
