The database on small ribosomal subunit RNA structure contained 1804 nucleotide sequences on April 23, 1993. This number comprises 365 eukaryotic, 65 archaeal, 1260 bacterial, 30 plastidial, and 84 mitochondrial sequences. These are stored in the form of an alignment in order to facilitate the use of the database as input for comparative studies on higher-order structure and for reconstruction of phylogenetic trees. The elements of the postulated secondary structure for each molecule are indicated by special symbols. The database is available on-line directly from the authors by ftp and can also be obtained from the EMBL nucleotide sequence library by electronic mail, ftp, and on CD ROM disk.
1993年4月23日,小核糖体亚基RNA结构数据库包含1804个核苷酸序列。这个数字包括365个真核生物、65个古细菌、1260个细菌、30个质体和84个线粒体序列。这些序列以比对的形式存储,以便于将该数据库用作高阶结构比较研究的输入以及系统发育树重建的输入。每个分子假定二级结构的元件由特殊符号表示。该数据库可通过ftp直接从作者处在线获取,也可通过电子邮件、ftp从EMBL核苷酸序列文库获取,还可从CD ROM光盘获取。
