THE TRANSLATIONAL TERMINATION SIGNAL DATABASE

The Translational Termination Database (Trans Term) consists of the im mediate context sequences around the natural termination codons from 4 5 organisms, and summarY tables. The influence of termination codon co ntext on their effectiveness as stop signals has been widely documente d. The SPECIES-TRI.DAT table shows trinucleotide stop codon usage in e ach organism and for comparison the occurrence of these sequences in t he noncoding region. The SPECIES-TETRA.DAT table contains is a similar table of tetranucleotide stop signal usage. The database is available from EMBL.
