F The peptide production method of the present invention produces a peptide (SEQ ID NO: 1) of a protein from
Plasmodium falciparum
, which is effective as a malaria vaccine. The method produces the peptide of SEQ ID NO: 1 by linking the fragments (i) through (v) shown below:
(v)
Asn-Asn-Asp-Xaa;
(SEQ ID NO: 2)
(iv)
Asp-Phe-Lys-Thr-Pro;
(SEQ ID NO: 3)
(iii)
Asn-Lys-Thr-Tyr-Asp-Leu;
(SEQ ID NO: 4)
(ii)
Phe-Tyr-Asn-Ser-Glu;
(SEQ ID NO: 5)
and
(i)
Xaa-Ala-Ser-Glu,
(SEQ ID NO: 6)
where ‘Xaa’ in (i) and (v) represents zero or any arbitrary number of amino acid residues.
本发明的肽生产方法生产了一种来自恶性疟原虫的蛋白质肽(

SEQ ID NO: 1的肽:(v)Asn-Asn-Asp-Xaa;(
SEQ ID NO: 2)(iv)Asp-Phe-Lys-Thr-Pro;(
SEQ ID NO: 3)(iii)Asn-Lys-Thr-Tyr-Asp-Leu;(
SEQ ID NO: 4)(ii)Phe-Tyr-Asn-
SEr-Glu;(
SEQ ID NO: 5)和(i)Xaa-Ala-
SEr-Glu,(
SEQ ID NO: 6)其中(i)和(v)中的“Xaa”代表零或任意数量的
氨基酸残基。
