Aromatic hydrocarbon dioxygenases in environmental biotechnology
TL;DR: Aromatic hydrocarbon dioxygenases have a broad substrate specificity and catalyze enantiospecific reactions with a wide range of substrates and make them attractive synthons for the production of industrially and medically important chiral chemicals.
Journal ArticleDOI
Rieske business: structure-function of Rieske non-heme oxygenases.
TL;DR: Rieske non-heme iron oxygenases catalyze stereo- and regiospecific reactions and the orientation of binding of the substrate to the enzyme is hypothesized to control the substrate selectivity and regio-specificity of product formation.
Journal ArticleDOI
Toluene-Degrading Bacteria Are Chemotactic towards the Environmental Pollutants Benzene, Toluene, and Trichloroethylene
TL;DR: This demonstration that soil bacteria can sense and swim towards the toxic compounds toluene, benzene, TCE, and related chemicals suggests that the introduction of chemotactic bacteria into selected polluted sites may accelerate bioremediation processes.

Plasmid-Encoded Phthalate Catabolic Pathway in Arthrobacter keyseri 12B
TL;DR: Activities of the eight enzymes involved in the catabolism of phthalate through protocatechuate to pyruvate and oxaloacetate were demonstrated in cells or cell extracts of recombinant E. coli strains.
Journal ArticleDOI
Directed evolution of toluene ortho-monooxygenase for enhanced 1-naphthol synthesis and chlorinated ethene degradation.
TL;DR: Results show clearly that random, in vitro protein engineering can be used to improve a large multisubunit protein for multiple functions, including environmental restoration and green chemistry.

Diverse Oxygenations Catalyzed by Carbazole 1,9a-Dioxygenase from Pseudomonas sp. Strain CA10
Hideaki Nojiri,Jeong-Won Nam,Mikiko Kosaka,Kenichi Morii,Tetsuo Takemura,Kazuo Furihata,Hisakazu Yamane,Toshio Omori +7 more
TL;DR: Results indicate that CARDO has a broad substrate range and can catalyze diverse oxygenation: angular dioxygenation, cis dihydroxylation, and monooxygenation.
Journal ArticleDOI
Enzyme specificity of 2-nitrotoluene 2,3-dioxygenase from Pseudomonas sp. strain JS42 is determined by the C-terminal region of the alpha subunit of the oxygenase component.
TL;DR: Comparisons of the substrates oxidized by these dioxygenases show that they differ in substrate specificity, regiospecificity, and the enantiomeric composition of their oxidation products.

Substrate Specificities of Hybrid Naphthalene and 2,4-Dinitrotoluene Dioxygenase Enzyme Systems
TL;DR: It is indicated that the small subunit of the oxygenase is essential for activity but does not play a major role in determining the specificity of these enzymes.
