Two C or not two C: recurrent disruption of Zn-ribbons, gene duplication, lineage-specific gene loss, and horizontal gene transfer in evolution of bacterial ribosomal proteins
U.S. Department of Health & Human Services —
Background Ribosomal proteins are encoded in all genomes of cellular life forms and are, generally, well conserved during evolution. In prokaryotes, the genes for... -

Conservation of the binding site for the arginine repressor in all bacterial lineages
U.S. Department of Health & Human Services —
Background: The arginine repressor ArgR/AhrC is a transcription factor universally conserved in bacterial genomes. Its recognition signal (the ARG box), a weak... -

Genome trees constructed using five different approaches suggest new major bacterial clades
U.S. Department of Health & Human Services —
Background The availability of multiple complete genome sequences from diverse taxa prompts the development of new phylogenetic approaches, which attempt to... -

Asymmetric directional mutation pressures in bacteria
U.S. Department of Health & Human Services —
When there are no strand-specific biases in mutation and selection rates between the two strands of DNA, the average nucleotide composition is theoretically expected... -

Evidence for symmetric chromosomal inversions around the replication origin in bacteria
U.S. Department of Health & Human Services —
Background: Whole-genome comparisons can provide great insight into many aspects of biology. Until recently, however, comparisons were mainly possible only between... -

A tandem repeats database for bacterial genomes: application to the genotyping of
U.S. Department of Health & Human Services —
Background Some pathogenic bacteria are genetically very homogeneous, making strain discrimination difficult. In the last few years, tandem repeats have been...
