上述したヌクレオチド鎖のラベル化、標識化、固定化の課題を解決するものとして、ヌクレオチド鎖の3´末端部を直接的に修飾物質で修飾する方法が提案されている(特許文献10参照)。この方法は、ヌクレオチド鎖の3´側に2つ以上のウラシル塩基を付加させ、付加したウラシルのグリコシド結合をウラシルDNAグリコシラーゼで分解して、3´末端にアルデヒド基を形成させ、このアルデヒド基とアミノ基を有する修飾物質とを共有結合させることにより、ヌクレオチド鎖の3´末端を修飾する。 In order to solve the above-mentioned problems of labeling, labeling, and immobilizing a nucleotide chain, a method of directly modifying the 3 ′ end of the nucleotide chain with a modifying substance has been proposed (see Patent Document 10). This method, by adding two or more uracil bases 3 'side of the nucleotide chain, the glycosidic bond of the added uracil was decomposed with uracil DNA glycoside la chromatography peptidase, to form aldehyde groups on the 3' end, the The 3 ′ end of the nucleotide chain is modified by covalently bonding an aldehyde group and a modifying substance having an amino group.
この問題を解決するものとして特許文献10記載の方法が提案されており、ヌクレオチド鎖の鎖長に関係なく、ヌクレオチド鎖の3´側を直接的に簡便に任意の修飾物質で修飾して、安定に保持可能な方法であるが、その一方で、付加したウラシルのグリコシド結合をウラシルDNAグリコシラーゼにより分解する原理から理解されるように、ヌクレオチド鎖中にウラシル塩基の配列が存在しない時しか実施できないという制約を有している。 As a method for solving this problem, a method described in Patent Document 10 has been proposed, and the 3 ′ side of the nucleotide chain is directly and simply modified with an arbitrary modifying substance, regardless of the chain length of the nucleotide chain. is a method that can be held in, on the other hand, the added glycosidic bonds uracil as is understood from the principles decomposed by uracil DNA glycoside la chromatography peptidase only when the sequence of the uracil bases are not present in the nucleotide chain There is a restriction that it cannot be implemented.
反応性を有する官能基として、アルデヒド基を形成することができる。
特定の塩基がヒポキサンチンであり、分解酵素が3−メチルアデニンDNAグリコラーゼであるのが好ましい。特定の塩基および分解酵素は種々の組合せが可能であるが、たとえばウラシル塩基のヌクレオチド鎖への組み込みは、遺伝子解析の様々な手法の中で汎用されているため、これを特定の塩基として利用することは望ましくない場合がある。汎用頻度の低いヒポキサンチン塩基とその分解酵素を利用することで、ヌクレオチド鎖の3´末端修飾を実施する際の利用者の利便性を大幅に向上することが可能となる。また、ヌクレオチド鎖の塩基の構成や鎖長に関わらず、ヌクレオチド鎖の3´末端側を直接的に簡便に、任意の修飾物質で、定量的、安定的に修飾することが可能となる。ヌクレオチド鎖内への不必要な塩基配列、修飾された塩基の取り込みを排除し、ヌクレオチド鎖の3´末端に限定して修飾物質で修飾できる方法である。
An aldehyde group can be formed as a functional group having reactivity.
Particular base is hypoxanthine, decomposing enzyme is preferably a 3-methyl adenine DNA glycolate La over zero. Although various combinations of specific bases and degrading enzymes are possible, for example, incorporation of a uracil base into a nucleotide chain is widely used in various methods of gene analysis, and this is used as a specific base. That may not be desirable. By using a hypoxanthine base and its degrading enzyme, which are less commonly used, it is possible to greatly improve the convenience of the user when modifying the 3 ′ end of the nucleotide chain. In addition, regardless of the base configuration or chain length of the nucleotide chain, the 3 ′ end side of the nucleotide chain can be directly and simply modified quantitatively and stably with an arbitrary modifying substance. In this method, unnecessary nucleotide sequences and modified bases are not incorporated into the nucleotide chain, and the modification can be performed with a modifying substance limited to the 3 ′ end of the nucleotide chain.
なお、この実施の形態1では、ヒポキサンチン塩基を有するヌクレオチド(A)をテーリングさせ、3−メチルアデニンDNAグリコシラーゼII型を作用させる例を示したが、これに限らず、以下の表1に例示するDNAグリコシラーゼあるいはDNA修復酵素と各塩基を有するヌクレオチドのテーリングとを組み合せても、同様にしてヌクレオチド鎖の3´末端を修飾物質で直接的に修飾できる。 In accordance with this embodiment 1, by tailing the nucleotide (A) having hypoxanthine base, an example of the action of 3-methyl-adenine DNA glycosyl La over peptidase II, not limited thereto, the following table be combined DNA glycosyl La over peptidase or DNA repair enzymes exemplified in 1 and the tailing of nucleotides with the nucleotide can be directly modifying the 3'-end of the nucleotide chain with a modifier material in the same manner.
(実施の形態2)
本発明の実施の形態2を図2に基づいて説明する。図中、mは、0または任意の自然数を表わし、Baseは、アデニン、グアニン、シトシン、チミン、ウラシル等の任意の塩基を示す。
(Embodiment 2)
A second embodiment of the present invention will be described with reference to FIG. In the figure, m represents 0 or an arbitrary natural number, and Base represents an arbitrary base such as adenine, guanine, cytosine, thymine, uracil.
フルオレセインのほかに、アミノ基を有するテキサスレッド、ローダミン、Cy3・Cy5に代表されるシアニン系化合物、ジゴギシゲニン、ビオチン等を用いて同様に、ラベル化、標識化することが可能である。 In addition to fluorescein, labeling and labeling can be carried out in the same manner using amino acids-containing Texas red, rhodamine, cyanine compounds represented by Cy3 / Cy5, digigosigenin, biotin and the like.
これは、テーリングしたヒポキサンチンのヌクレオチド鎖部分にオリゴデオキシシトシンがランダムにアニールするため、部分的に2本鎖が形成されず、3−メチルアデニンDNAグリコシラーゼII型が作用しない箇所が存在してしまうためである。 This is because the nucleotide chain portion of hypoxanthine were tailing oligodeoxynucleotides cytosine anneal randomly partially without 2 strand is formed, 3-methyl adenine DNA glycosyl La chromatography locations peptidase II type does not act exists It is because it will do.
