使用了恶性疟原虫的烯醇化酶蛋白质的部分序列的人工抗原及其制造方法
Abstract:
本发明提供一种生理活性肽，其带有恶性疟原虫烯醇化酶的部分氨基酸序列，具有与GMP制造时的标准设定对应的分子结构。所述肽具有如下结构：具有(i)A01‑Ala‑Ser‑Glu‑Phe‑Tyr‑Asn‑Ser‑Glu‑Asn‑Lys‑Thr‑Tyr‑Asp‑Leu‑Asp‑Phe‑Lys‑Thr‑Pro‑Asn‑Asn‑Asp‑A02(序列号1)或(ii)A03‑Ala‑Ser‑Glu‑Phe‑Tyr‑Asn‑Ser‑Glu‑Asn‑Lys‑Thr‑Tyr‑Asp‑Leu‑Asp‑Phe‑Lys‑Thr‑Pro‑Asn‑Asn‑Asp‑Lys‑Ser‑Leu‑Val‑Lys‑Thr‑A04(序列号2)的氨基酸序列的2个肽通过各自的羧基末端与(iii)Lys‑A05‑Cys‑A06所示连接肽的Lys的2个氨基之间的酰胺键排列成2分支状。优选地，所述肽具有通过该肽内的连接肽序列的Cys残基间的S‑S键而二聚化的结构。(i)、(ii)、(iii)中，A01至A06是包含0的任意数目的氨基酸残基。
Abstract(English):

Provided is a physiologically active peptide which comprises a partial amino acid sequence of enolase originated from Plasmodium falciparum and which has a molecular structure that meets the standards set for the production of GMP. A peptide having such a structure that two peptide molecules each comprising (i) an amino acid sequence A01-Ala-Ser-Glu-Phe-Tyr-Asn-Ser-Glu-Asn-Lys-Thr-Tyr-Asp-Leu-Asp-Phe-Lys-Thr-Pro-Asn-Asn-Asp-A02 (SEQ ID NO: 1) or (ii) an amino acid sequence A03-Ala-Ser-Glu-Phe-Tyr-Asn-Ser-Glu-Asn-Lys-Thr-Tyr-Asp-Leu-Asp-Phe-Lys-Thr-Pro-Asn-Asn-Asp-Lys-Ser-Leu-Val-Lys-Thr-A04 (SEQ ID NO: 2) are lined to a liker peptide represented by (iii) Lys-A05-Cys-A06 in such a manner that the two peptide molecules can be arranged in a biantennary form through amide bonds between carboxyl terminal of the two peptide molecules and two amino groups in a Lys residue in the linker peptide. Preferably, the peptide has a dimerized structure, in which the peptides are dimerized through an S-S bond formed between a Cys residue in the sequence for the linker peptide in one of the peptides and a Cys residue in the sequence for the linker peptide in the other of the peptides. (In the amino acid sequences (i), (ii) and (iii), each of A01 to A06 represents a molecule composed of an arbitrary number, including 0, of amino acid residues.)
