The TransTerm database of sequence contexts of stop and start codons has been expanded to include approximately 50% more species than last year's release. It now contains 148 organisms and >39 500 coding sequences; it is now available on the World Wide Web. The database includes: (i) initiation and termination sequence contexts organized by species; (ii) summary parameters about the individual sequences (sequence length, GC%, GC3, Nc, CAI) in addition to tables of base frequencies for each species' stop and start codon sequence context; (iii) species codon usage tables; and (iv) summary tables of stop signal frequency.
终止密码子和起始密码子序列上下文的TransTerm数据库已得到扩充,所涵盖的物种比去年发布时增加了约50%。目前该数据库包含148种生物和超过39500个编码序列,现已在万维网上提供。该数据库包括:(i) 按物种组织的起始和终止序列上下文;(ii) 除了每个物种终止密码子和起始密码子序列上下文的碱基频率表之外,关于各个序列的汇总参数(序列长度、GC%、GC3、Nc、CAI);(iii) 物种密码子使用表;以及(iv) 终止信号频率汇总表。
