tRNAscan-SE analysis of complete genomes

The genomic tRNA database contains tRNA gene predictions made by tRNAscan-SE on complete or nearly complete genomes. Unless otherwise noted, all annotation is automated, and has not been inspected for agreement with published literature.

Note: The tRNAs listed in this version of GtRNAdb were predicted using the beta version of tRNAscan-SE 2.0. As we finalize the development of refined search models in tRNAscan-SE 2.0, the predicted tRNAs in this version of GtRNAdb may change slightly.

To access the previous version of GtRNAdb that includes gene predictions using the stable version of tRNAscan-SE 1.23 and 1.3, please click here
