Abstract
本发明公开了川桑色氨酸脱羧酶TDC及其应用,其中川桑色氨酸脱羧酶TDC的氨基酸序列如SEQ ID NO.4所示,将川桑色氨酸脱羧酶TDC基因克隆后构建原核表达系统,然后进行酶活测定,测得具有较高的色氨酸脱羧酶的活性,因此川桑色氨酸脱羧酶TDC可以作为工程菌的目的基因,川桑色氨酸脱羧酶TDC也可以作为体外催化L‑色氨酸转化为色胺的催化剂,具有很好的应用前景。
Description
技术领域
本发明涉及生物工程领域,具体涉及川桑色氨酸脱羧酶TDC,还涉及川桑色氨酸脱羧酶TDC的应用。
背景技术
褪黑素,学名N-乙酰基-5-甲氧基-色胺,是一种吲哚胺,色氨酸的代谢产物。目前已知它广泛存在于人体、动物体及植物体内,生理作用非常广泛。由于其首先在人体的松果体内被发现,因此又被称为松果体素。随后的研究发现,其广泛存在于人体内的各个部位,含量极少,只有pg(1×10-12g)/mL水平。目前已知的褪黑素的生理功能主要有调节生物体的昼夜节律,缓解睡眠障碍;抗氧化,褪黑素本身及其代谢产物不仅有强大的自由基清除能力,而且能够诱导生物体相关抗氧化酶活性增强,增强免疫作用,抗肿瘤,抗衰老,特别是对阿尔茨海默病有明显效果等优点。
长期以来褪黑素被认为是动物体内专有的,自从1995年在植物中检测到褪黑素之后,人们陆续在许多高等植物中也发现褪黑素存在。在动物中,褪黑素的生物合成途径已经非常清楚。在植物中褪黑素的合成途径包括3条:(1)色氨酸脱羧酶将色氨酸转化成色胺;色氨酸羟化酶将色胺转化为5-羟色胺;N-乙酰-5羟色胺转移酶将5-羟色胺转化为N-乙酰-5羟色胺;N-乙酰-5-羟色胺氧甲基转移酶或者咖啡酸氧甲基转移酶将N-乙酰-5羟色胺转化成褪黑素。(2)色氨酸脱羧酶将色氨酸转化成色胺;N-乙酰-5羟色胺转移酶将色胺转化为N-乙酰-5羟色胺;N-乙酰色胺氧甲基转移酶将N-乙酰-5羟色胺转化成褪黑素。(3)色氨酸脱羧酶将色氨酸转化成色胺;色氨酸羟化酶将色胺转化为5-羟色胺;N-乙酰-5-羟色胺氧甲基转移酶或者咖啡酸氧甲基转移酶将5-羟色胺转化成5-甲氧基-色胺;N-乙酰色胺转移酶将5-甲氧基-色胺转化成褪黑素。在植物中,褪黑素合成的酶促反应中的前两步反应不同于动物中褪黑素合成的前两步反应。第一步反应产物是色氨酸被催化生产色胺而不是5-羟色氨酸,第二步酶促反应是色胺被色胺-5-羟化酶催化形成5-羟色胺。在这两步特异反应中起关键作用的是TDC催化L-色氨酸生成了色胺,该反应高度特异且在反应中酶活较高。TDC是芳香族-L-氨基酸脱羧酶,被认为是褪黑素合成过程中的第一个限速酶。
川桑中含有褪黑素,但是其含量极低,并不能大量提取获得。因此,研究褪黑素合成途径的第一个限速酶及其基因,有利于体外合成途径的建立,为褪黑素规模化生产点奠定基础。

本发明使用色胺(Sigma,市售价195元/5G)作为标品对照,检验色氨酸脱羧酶基因所表达的酶活性。
实施例1、川桑色氨酸脱羧酶基因TDC克隆
根据Morus.TDC datebase上已报道的Morus.TDC色氨酸脱羧酶基因(Morus002214)设计引物进行扩增,TDC上游引物为:5'-ggggtaccatgggtagccttggtttt-3'(SEQ ID NO.1),TDC下游引物为:5'-acgcgtcgacttatacacttctgagcac-3'(SEQ ID NO.2),提取Morus RNA,反转录为cDNA。然后以合成的cDNA为模板,SEQ ID NO.1和SEQ ID NO.2所示序列为引物进行PCR扩增,扩增产物进行电泳检测,结果如图1所示。回收目的片段,回收产物与pMD19-T载体连接,转入E.coli.Trans1-T1感受态细胞,获得的阳性克隆送往华大基因公司测序,结果显示,TDC基因全长编码的核苷酸序列如SEQ ID NO.3所示,编码的氨基酸如SEQ ID NO.4所示。
实施例2、川桑色氨酸脱羧酶基因TDC重组载体构建及原核表达
