AAindex 是氨基酸指数和氨基酸突变矩阵的数据库。氨基酸指数是一组 20 个数值,代表氨基酸的各种理化和生化特性。氨基酸突变矩阵通常是表示氨基酸相似性的20×20数值。 AAindex 由两部分组成:AAindex1 用于收集已发表的氨基酸索引,AAindex2 用于收集已发表的氨基酸突变矩阵。 AAindex1 或 AAindex2 的每个条目由定义、参考信息、相关系数和实际数据方面的相关条目列表组成。该数据库可以通过 GenomeNet (http://www.genome.ad.jp/aaindex/) 上的 DBGET/LinkDB 系统访问,也可以通过匿名 FTP (ftp://ftp.genome.ad.jp/db/genomenet/aaindex/) 下载。
AAindex is a database of amino acid indices and amino acid mutation matrices. An amino acid index is a set of 20 numerical values representing various physicochemical and biochemical properties of amino acids. An amino acid mutation matrix is generally 20 x 20 numerical values representing similarity of amino acids. AAindex consists of two sections: AAindex1 for the collection of published amino acid indices and AAindex2 for the collection of published amino acid mutation matrices. Each entry of either AAindex1 or AAindex2 consists of the definition, the reference information, a list of related entries in terms of the correlation coefficient and the actual data. The database may be accessed through the DBGET/LinkDB system at GenomeNet (http://www. genome.ad.jp/aaindex/) or may be down loaded by anonymous FTP (ftp://ftp.genome.ad.jp/db/genomenet/ aaindex/).
