The mxaAKL genes of Methylobacter albus BG8
Article Abstract:
The mxa locus of the gram negative bacteria Methylobacter albus BG8 corresponds to mxaACKDL and encodes five polypeptides. The mxa locus is identifiable via hybridization with the mxaLD, mxaA and mxaK probes prepared from Methylobacter extorquens AM1 genes. The order of the mxaL and mxaD genes in M. albus is opposite to that in M. extorquens. All five genes can be expressed in Escherichia coli. A sixth polypeptide is encoded by a region downstream of the mxa locus.

DNA topology and the global control of bacterial gene expression: implications for the regulation of virulence gene expression
Article Abstract:
Many bacterial species share common regulators such as H-NS protein which has a negative effect on the virB promotor in Shigella flexneri and the fimA promotor in Escherichia coli. Bacterial cells contain global regulators such as the catabolic regulatory protein and other factors which affect DNA structure. DNA topology in bacterial cells depends on environmental conditions, DNA supercoiling, transcription, low molecular-mass and DNA-topology-altering proteins.

Phylogeny of the genus Haemophilus as determined by comparison of partial infB seuences
Article Abstract:
DNA hybridization and infB gene analysis in 66 clinical isolates of Haemophilus indicate that human isolates are dependent on X and V factors. A true 'Haemophilus sensu stricto', as determined by 16S RRNA sequence comparison, does not exist in the phylogeny of Haemophilus genus.
