Orthologs and paralogs are two fundamentally different types of homologous genes that
evolved, respectively, by vertical descent from a single ancestral gene and by duplication …

We have developed a general profile for the proteins of the TetR family of repressors. The
stretch that best defines the profile of this family is made up of 47 amino acid residues that …

Bacterial pathogens continue to impose a major threat to public health worldwide in the 21st
century. Intensified studies on bacterial pathogenesis have greatly expanded our knowledge …

Lactobacillus acidophilus NCFM is a probiotic bacterium that has been produced
commercially since 1972. The complete genome is 1,993,564 nt and devoid of plasmids …

We analyzed length differences of eukaryotic, bacterial and archaeal proteins in relation to
function, conservation and environmental factors. Comparing Eukaryotes and Prokaryotes …

We combine comparative genomic measures and the distance separating adjacent genes to
predict operons in 124 completely sequenced prokaryotic genomes. Our method …

The bacterium Caulobacter crescentus and related stalk bacterial species are known for
their distinctive ability to live in low-nutrient environments, a characteristic of most heavy …

Sulfolobus acidocaldarius is an aerobic thermoacidophilic crenarchaeon which grows
optimally at 80° C and pH 2 in terrestrial solfataric springs. Here, we describe the genome …

Bacterial response to nitric oxide (NO) is of major importance since NO is an obligatory
intermediate of the nitrogen cycle. Transcriptional regulation of the dissimilatory nitric oxides …

Staphylococcus saprophyticus is a uropathogenic Staphylococcus frequently isolated from
young female outpatients presenting with uncomplicated urinary tract infections. We …
