| 摘 要： | 从KEGG数据库中获得厚壁菌门下的18种细菌的蛋白质和氨基酸序列,运用生物信息学方法重建了这18个物种的发育树以及祖先的氨基酸序列,得到了18个现存物种及其祖先物种的氨基酸组成偏好情况。结果表明,现存物种的蛋白质的氨基酸组成有偏好,而在祖先蛋白质中也存在着氨基酸偏好的现象。对于每一种氨基酸,各物种的使用偏好不完全相同。研究结果为今后透彻地研究厚壁菌门细菌打下了基础。

| Abstract: | This paper obtained 18 bacteria proteins and amino acid sequences under Firmicutes from the KEGG database,using bioinformatics methods to reconstruct the development of the 18 tree species and the ancestor of the amino acid sequence,with 18 extant species and their ancestral species has preference for the amino acid composition of the situation.The results showed that the existing amino acid composition of species has preference,and in the ancestral amino acid protein,there are also the phenomenon of prefer... |
