Key result
The TransTerm-98 database was expanded to include over 130,000 non-redundant coding sequences and associated untranslated regions from over 450 species.
TransTerm-98 provides an expanded, publicly accessible database of mRNA sequences and parameters for analyzing translational control signals across hundreds of species.
Answers are grounded in this paper and cite their sources.
Expands resource for cross-species translational analysis; extends prior versions but leaves open validation for specific applications.
TransTerm is a database of mRNA sequences and parameters useful for detecting translational control signals in general. TransTerm-98 has been expanded beyond previous years to include full coding sequences and UTRs, while retaining the original small contexts about the coding sequence start- and stop-codons. The database contains more than 130 000 non-redundant coding sequences with associated untranslated regions (UTRs) from over 450 species. This includes the complete genomes of 12 prokaryotic and one eukaryotic organism. Several coding sequence parameters are available: coding sequence length, Nc, GC3 and, when it is computable, Codon Adaptation Index (CAI). Codon usage tables and summaries of start- and stop-codon contexts are also included. TransTerm-98 has both a relational database form with a WWW interface and a flatfile format, also available by Internet browser. TransTerm is available at: http://biochem.otago.ac.nz:800/Transterm/homepage.h tml
