Beschreibung
Zusammenfassung:	The invention discloses a lanthiopeptin precursor peptide amyA2 as well as a preparation method and application thereof, and relates to the technical field of biology. An amino acid sequence of the lanthiopeptin precursor peptide amyA2 is shown in SEQ ID NO:1. When the lanthiopeptin precursor peptide amyA2 is added in the fermentation process of bacillus amyloliquefaciens, the antibacterial activity of metabolites of the bacillus amyloliquefaciens can be significantly improved, and the duration time of the antibacterial activity is three times or more of original antibacterial activity. 本发明公开了一种羊毛硫肽前体肽amyA2及其制备方法和应用，涉及生物技术领域。羊毛硫肽前体肽amyA2的氨基酸序列如SEQ ID NO:1所示。在解淀粉芽孢杆菌发酵过程中添加本发明羊毛硫肽前体肽amyA2，可以显著提高解淀粉芽孢杆菌代谢产物抗菌活性，抗菌活性持续时间是原来的3倍以上。
