PubMed Central McBride, M. J., Weinberg, R. A. Ongoing evolution of Pseudomonas aeruginosa PAO1 sublines complicates studies of DNA damage repair and tolerance. These regulatory genes presumably modulate the diverse genetic and biochemical capabilities of this bacterium in changing environmental conditions. For example, it possesses four dicarboxylate permeases of the TRAP-T type (E. coli has only one), and has only two phosphotransferase system (PTS) sugar transportersfor fructose and N-acetylglucosamine (E. coli has more than twenty)17. DO is the President and CEO of Owen Biosciences Inc. With the advent of pulsed-field gel electrophoresis (PFGE), a physical map of the PAO1 genome was constructed (32) and later merged with the genetic map information (12). Here we report the sequencing of the genome of P. aeruginosa. However, it is the membrane-bound nitrate reductase NarG, but not the periplasmic enzyme NapA, that is essential to sustain anaerobic growth (30). Genomic and Phenotypic Diversity among Ten Laboratory Isolates of. (Fig.1E)1E) is syntenic with PA0727 to PA0717 (RGP5) and shows 94% to 100% sequence identity between the individual homologs (see Table S4 in the supplemental material). When we analysed the P. aeruginosa, E. coli, B. subtilis and M. tuberculosis genomes by BLASTP comparisons between all predicted ORFs within each organism, we found that the P. aeruginosa genome has significantly more distinct gene families (paralogous groups) than the other large bacterial genomes (see Supplementary Information ). (Fig.1C)1C) because both SpeI and DpnI have recognition sites in the 23S rRNA gene sequence and hence do not visualize the inversion between the rrn operons. First, the PAO1-UW subline maintained in our laboratory showed intragenic deletions in PA1695 and PA3760 compared to the published PAO1-UW sequence. Genome sequencing of the chromosomes of PAO1 sublines MPAO1 and PAO1-DSM by Genome Analyzer sequencing-by-synthesis technology uncovered 39 validated single-nucleotide deviations (SNPs) from the PAO1-UW database entries (Table (Table1;1; Fig. Comparison of R9.4.1/Kit10 and R10/Kit12 Oxford Nanopore flowcells and chemistries in bacterial genome reconstruction.
