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 کاملCharacterization of the second LysR-type regulator in the biphenyl-catabolic gene cluster of Pseudomonas pseudoalcaligenes KF707.
Pseudomonas pseudoalcaligenes KF707 possesses a biphenyl-catabolic (bph) gene cluster consisting of bphR1A1A2-(orf3)-bphA3A4BCX0X1X2X3D. The bphR1 (formerly orf0) gene product, which belongs to the GntR family, is a positive regulator for itself and bphX0X1X2X3D. Further analysis in this study revealed that a second regulator belonging to the LysR family (designated bphR2) is involved in the re...
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 کاملBiphenyl Modulates the Expression and Function of Respiratory Oxidases in the Polychlorinated-Biphenyls Degrader Pseudomonas pseudoalcaligenes KF707
Pseudomonas pseudoalcaligenes KF707 is a soil bacterium which is known for its capacity to aerobically degrade harmful organic compounds such as polychlorinated biphenyls (PCBs) using biphenyl as co-metabolite. Here we provide the first genetic and functional analysis of the KF707 respiratory terminal oxidases in cells grown with two different carbon sources: glucose and biphenyl. We identified...
متن کاملDraft Genome Sequence of Pseudomonas toyotomiensis KF710, a Polychlorinated Biphenyl-Degrading Bacterium Isolated from Biphenyl-Contaminated Soil
Pseudomonas toyotomiensis KF710 utilizes biphenyl and degrades polychlorinated biphenyls (PCBs). Here, we report the genome sequence of the KF710 strain, consisting of 5,596,721 bp with 5,155 coding sequences. The biphenyl catabolic genes were almost identical to those of Pseudomonas pseudoalcaligenes KF707, one of the most well-characterized biphenyl-utilizing strains.
