| 摘要: |
| 通过GenBank数据库寻找能产生表面活性素、伊枯草菌素或丰原素并在基因组中其合成基因已得到注释的芽胞杆菌，经过BLAST比对序列初步确定这三类脂肽类抗菌肽的合成基因簇的位置，再运用antiSMASH进行其合成基因簇的最终定位.对表面活性素、伊枯草菌素和丰原素的结构及相关的合成酶结构域进行了预测与分析. |

| Abstract: |
| In this study,the GenBank database was used to search for Bacillus which could produce surfactin,iturin or fengycin and its synthetic genes were annotated in the genome.The location of the synthetic gene clusters of these three lipopeptide antibiotics were determined by BLAST alignment.Then antiSMASH was used to determine the final location of the synthetic gene clusters.Further,we predicted and analyzed the structure and related synthetase domains of the surfactin,iturin and fengycin. |
| Key words: bioinformatics Bacillus velezensis S3-1 surfactin iturin fengycin |
