Provision of a physiologically active peptide having a partial amino acid sequence of P. falciparum enolase and having a molecular structure corresponding to a standard setting at the time of GMP production. (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 (SEQ ID NO: 1) or (ii) A03-Ala-Ser-Glu-Phe-Tyr-Asn-Ser-Glu-Asn-Lys-Thr-Tyr-Asp-Leu-Asp-Phe-Lys-Thr-Pro-Asn Two peptides having the amino acid sequence of -Asn-Asp-Lys-Ser-Leu-Val-Lys-Thr-A04 (SEQ ID NO: 2) are represented by their carboxy terminus and (iii) Lys-A05-Cys-A06. A peptide having a structure arranged in two branches by an amide bond with two amino groups of Lys of the linker peptide. Preferably, the peptide has a structure dimerized by an S—S bond between Cys residues of a linker peptide sequence in the peptide. (In (i), (ii), and (iii), A01 to A06 represent any number of amino acid residues including 0.)熱帯熱マラリア原虫エノラーゼの部分アミノ酸配列を持つ、GMP製造時の規格設定に対応した分子構造を有する生理活性ペプチドの提供。(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(配列番号1)または(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(配列番号2)のアミノ酸配列を有するペプチド2つが、それぞれのカルボキシ末端と、(iii)Lys-A05-Cys-A06で表されるリンカーペプチドのLysの2つのアミノ基とのアミド結合により2分岐状に並べられた構造を有するペプチド。好ましくは該ペプチドが、該ペプチド内のリンカーペプチド配列のCys残基間のS-S結合によって2量化された構造を有するペプチド。((i)、(ii)、(iii)において、A01からA06は0を含む任意の数のアミノ酸残基を示す。)
