A program is described, tRNAscan-SE, which identifies 99-100% of transfer RNA genes in DNA sequence while giving less than one false positive per 15 gigabases.
Abstract
We describe a program, tRNAscan-SE, which identifies 99-100% of transfer RNA genes in DNA sequence while giving less than one false positive per 15 gigabases. Two previously described tRNA detection programs are used as fast, first-pass prefilters to identify candidate tRNAs, which are then analyzed by a highly selective tRNA covariance model. This work represents a practical application of RNA covariance models, which are general, probabilistic secondary structure profiles based on stochastic context-free grammars. tRNAscan-SE searches at approximately 30 000 bp/s. Additional extensions to tRNAscan-SE detect unusual tRNA homologues such as selenocysteine tRNAs, tRNA-derived repetitive elements and tRNA pseudogenes.

Mechanisms of Thermal Adaptation Revealed From the Genomes of the Antarctic Archaea Methanogenium frigidum and Methanococcoides burtonii

TL;DR: Comparative genomics revealed trends in amino acid and tRNA composition, and structural features of proteins from cold-adapted Archaea, and indicated that GC content is the major factor influencing tRNA stability in hyperthermophiles, but not in the psychrophiles, mesophiles or moderate thermophiles

Complete genome sequence of the entomopathogenic and metabolically versatile soil bacterium Pseudomonas entomophila

TL;DR: Genome-wide random mutagenesis revealed the major role of the two-component system GacS/GacA that regulates most of the potential virulence factors identified and contributed to P. entomophila's entomopathogenic properties.

Sequencing and analysis of the large virulence plasmid pLVPK of Klebsiella pneumoniae CG43.

TL;DR: The entire DNA sequence of pLVPK, which is a 219-kb virulence plasmid harbored in a bacteremic isolate of Klebsiella pneumoniae, is determined and the presence of 13 insertion sequences located mostly at the boundaries of the aforementioned gene clusters suggests that pL VPK was derived from a sequential assembly of various horizontally acquired DNA fragments.
