Universal trees based on large combined protein sequence data setsJ R Brown
Anti Microbial Bioinformatics Group, GlaxoSmithKline, 1250 South Collegeville Road, UP1345 P O Box 5089, Collegeville, Pennsylvania 19426 0989, USA
Nat Genet 28:281-5. 2001..Thus, combined protein universal trees are highly congruent with SSU rRNA trees in their strong support for the separate monophyly of domains as well as the early evolution of thermophilic Bacteria...
Genomic and phylogenetic perspectives on the evolution of prokaryotesJ R Brown
Microbial Bioinformatics Department, Division of Bioinformatics, Glaxo SmithKline Pharmaceuticals, 1250 South Collegeville Road, P O Box 5089, UP1345, Collegeville, Pennsylvania 19426 0989, USA
Syst Biol 50:497-512. 2001..Promising new approaches to genomic analyses, which could add to our understanding prokaryotic evolution and help in their classification, are discussed...
Systematic identification of selective essential genes in Helicobacter pylori by genome prioritization and allelic replacement mutagenesisA F Chalker
Department of Anti Infective Research, SmithKline Beecham Pharmaceuticals, Collegeville, Pennsylvania 19426, USA
J Bacteriol 183:1259-68. 2001..We propose that the products of a number of these H. pylori-specific essential genes may be suitable targets for novel anti-H. pylori therapies...
Gene descent, duplication, and horizontal transfer in the evolution of glutamyl- and glutaminyl-tRNA synthetasesJ R Brown
Department of Bioinformatics, SmithKline Beecham Pharmaceuticals, 1250 South Collegeville Road, UP1345, Collegeville PA 19426 0989, USA
J Mol Evol 49:485-95. 1999..Although all bacterial GlnRS form a monophyletic group, the broad phyletic distribution of this tRNA synthetase suggests that multiple gene transfers from eukaryotes to bacteria occurred shortly after the Archaea-eukaryote divergence...
Phylogenetic analyses do not support horizontal gene transfers from bacteria to vertebratesM J Stanhope
Bioinformatics, GlaxoSmithKline, Collegeville, PA 19426, USA
Nature 411:940-4. 2001..They are, therefore, unlikely to be examples of direct HGT from bacteria to vertebrates...
Lipid modification of prelipoproteins is dispensable for growth in vitro but essential for virulence in Streptococcus pneumoniaeC M Petit
GlaxoSmithKline Pharmaceuticals, Anti Microbial and Host Defense, Collegeville, PA 19426 0989, USA
FEMS Microbiol Lett 200:229-33. 2001..Our findings suggest a major difference in the role of lipoproteins in Gram-positive bacteria versus the proteobacteria...
