info Database description 

This is the most accurate tRNA gene database curated manually by experts in the world. This database is the outcome of the model project to utilize the expertise of elderly researchers and to pass it down to the next generation, which was carried out at Nagahama Institute of Bio-Science and Technology. Specifically, the existing multiple tRNA gene search programs are used for automatic search of tRNA gene from sequenced prokaryote, eukaryote and virus genomes and envrironmental DNA sequences, and then the experts manually check those cases in which different results are generated by program.

info Features and manner of utilization of database 

- The database was constructed by performing a comprehensive search of tRNA genes on 1625 full-length genomes and 2993 draft genomes of bacteria and Archaea, 151 complete virus genomes, 121 complete chloroplast genomes, 12 complete eukaryote (Plant and Fungi) genomes and about 230 million environmental DNA sequences.
- Three prediction programs (tRNAScan-SE, Aragorn and tRNA finder) are used together to search tRNA genes. If the prediction results do not match, curation is carried out by experts.
- The relationship between the codon usage frequency and the number of tRNA genes can be browsed for each species to search the codon recognized by major isoaccepting tRNA (optimal codon) or minor tRNA (nonoptimal codon).
