摘要: Object of the present invention is to provide a hemagglutinin-binding peptide producing an anti-influenza virus effect higher than that of existing peptides. The present invention provides, for example, a hemagglutinin-binding peptide comprising a polypeptide having any of the following amino acid sequences (i) to (iv):
(i) Thr-MeGly-Asp-MePhe-MePhe-Ser-MeSer-His-Tyr-Thr-Val-Pro-Arg (SEQ ID NO:1);
(ii) Arg-Val-Ser-MePhe-Thr-Tyr-MePhe-MeSer-Tyr-Thr-Pro-Ser (SEQ ID NO: 2);
(iii) an amino acid sequence with deletions, additions, or substitutions of one or several amino acids in SEQ ID NO: 1 or 2; and
(iv) an amino acid sequence having 90% or more sequence identity to that of SEQ ID NO: 1 or 2.摘要翻译: 本发明的目的是提供一种产生比现有肽更高的抗流感病毒作用的血凝素结合肽。 例如,本发明提供了包含具有任何以下氨基酸序列(i)至(iv)的多肽的血细胞凝集素结合肽:(i)Thr-MeGly-Asp-MePhe-MePhe-Ser-MeSer-His -Tyr-Thr-Val-Pro-Arg(SEQ ID NO:1); (ii)Arg-Val-Ser-MePhe-Thr-Tyr-MePhe-MeSer-Tyr-Thr-Pro-Ser(SEQ ID NO:2)。 (iii)在SEQ ID NO:1或2中具有一个或几个氨基酸缺失,添加或取代的氨基酸序列; 和(iv)与SEQ ID NO:1或2具有90%或更多序列同一性的氨基酸序列。
