Genome sequence of the polychlorinated-biphenyl degrader Pseudomonas pseudoalcaligenes KF707.
Pseudomonas pseudoalcaligenes KF707 is a soil polychlorinated biphenyl (PCB) degrader, able to grow both planktonically and as a biofilm in the presence of various toxic metals and metalloids. Here we report the genome sequence (5,957,359 bp) of P. pseudoalcaligenes KF707, which provides insights into metabolic degradation pathways, flagellar motility, and chemotaxis.
متن کاملReaction mechanism of protocatechuate 3,4-dioxygenase.
We have observed that high SOD-like function (decomposition of superoxide anion) was observed for several iron(III) compounds with tripodal ligands and several oxovanadium(IV) compounds, and also that these compounds exhibit high catalytic activity for oxidative cleavage of 3,5-di-tert-butylcatechol in non-donating solvents such as dichloromethane or nitromethane. These are suggesting that the ...
متن کاملAnalysis of bph operon from the polychlorinated biphenyl-degrading strain of Pseudomonas pseudoalcaligenes KF707.
The entire nucleotide sequences (6.8 kilobase pairs) of the bphABC genes and their products involved in the initial dioxygenation and ring-meta-cleavage of biphenyls and polychlorinated biphenyls were determined. The first bphA gene starts about a 100 base pairs downstream from the transcriptional initiation site. The bphA region, which encodes a cluster of enzymes including biphenyl dioxygenas...
متن کاملThe Role of cheA Genes in Swarming and Swimming Motility of Pseudomonas pseudoalcaligenes KF707
A genome analysis of Pseudomonas pseudoalcaligenes KF707, a PCBs degrader and metal-resistant soil microorganism, revealed the presence of two novel gene clusters named che2 and che3, which were predicted to be involved in chemotaxis-like pathways, in addition to a che1 gene cluster. We herein report that the histidine kinase coding genes, cheA2 and cheA3, have no role in swimming or chemotaxis...
متن کاملEfficient degradation of trichloroethylene by a hybrid aromatic ring dioxygenase.
Engineering of hybrid gene clusters between the toluene metabolic tod operon and the biphenyl metabolic bph operon greatly enhanced the rate of biodegradation of trichloroethylene. Escherichia coli cells carrying a hybrid gene cluster composed of todC1 (the gene encoding the large subunit of toluene terminal dioxygenase in Pseudomonas putida F1), bphA2 (the gene encoding the small subunit of bi...
