Purification and properties of ferredoxin BPH , a component of biphenyl 2,3-dioxygenase of Pseudomonas sp strain LB400

Autor: Dale A. Pelletier, J D Haddock, David T. Gibson

Publikováno v: Journal of Industrial Microbiology and Biotechnology. 19:355-359

The ferredoxin component (ferredoxinBPH) of biphenyl 2,3-dioxygenase was purified to homogeneity from crude cell extract of Pseudomonas sp strain LB400 using ion exchange, hydrophobic interaction and gel filtration column chromatography. The protein

Dihydroxylation and dechlorination of chlorinated biphenyls by purified biphenyl 2,3-dioxygenase from Pseudomonas sp. strain LB400

Autor: David T. Gibson, J R Horton, J D Haddock

Publikováno v: Journal of Bacteriology. 177:20-26

Oxidation of biphenyl and nine chlorinated biphenyls (CBs) by the biphenyl 2,3-dioxygenase from Pseudomonas sp. strain LB400 was examined. The purified terminal oxygenase required the addition of partially purified electron transport components, NAD(

Purification and characterization of the NADH:ferredoxinBPH oxidoreductase component of biphenyl 2,3-dioxygenase from Pseudomonas sp. strain LB400

Autor: Richard M. Broadus, J. D. Haddock

Publikováno v: Archives of microbiology. 170(2)

NADH:ferredoxinBPH oxidoreductase (reductaseBPH) of biphenyl 2,3-dioxygenase was purified over 47-fold to homogeneity with a yield of 41% from cell extract of Pseudomonas sp. strain LB400. ReductaseBPH transfers reducing equivalents from NADH to the

Initial steps in the anaerobic degradation of 3,4,5-trihydroxybenzoate by Eubacterium oxidoreducens: characterization of mutants and role of 1,2,3,5-tetrahydroxybenzene

Autor: James G. Ferry, J D Haddock

Chemical mutagenesis and antibiotic enrichment techniques were used to isolate five mutant strains of the obligate anaerobe Eubacterium oxidoreducens that were unable to grow on 3,4,5-trihydroxybenzoate (gallate). Two strains could not transform gall

Purification and properties of phloroglucinol reductase from Eubacterium oxidoreducens G-41

Autor: James G. Ferry, J D Haddock

Publikováno v: Journal of Biological Chemistry. 264:4423-4427

Phloroglucinol reductase was purified 90-fold to homogeneity from the anaerobic rumen organism Eubacterium oxidoreducens strain G-41. The enzyme is stable in the presence of air and is found in the soluble fraction after ultracentrifugation of cell e

Publikováno v: Archives of environmental contamination and toxicology. 11(1)

Uptake and depuration kinetics for benzo(a)pyrene (B(a)P) were determined for the midge Chironomus riparius (Diptera) with one and two compartment models. Nonfeeding animals were exposed to nominal 1.0 microgram.L-1 14C- B(a)P for eight hr. Depuratio
