Benzoic acid or benzoic acid esters substituted with one or more chlorine atoms.
Catechol 1,2-Dioxygenase
An enzyme that catalyzes the oxidation of catechol to muconic acid with the use of Fe3+ as a cofactor. This enzyme was formerly characterized as EC 1.13.1.1 and EC 1.99.2.2.
Biodegradation, Environmental
Elimination of ENVIRONMENTAL POLLUTANTS; PESTICIDES and other waste using living organisms, usually involving intervention of environmental or sanitation engineers.
Catechols
A group of 1,2-benzenediols that contain the general formula R-C6H5O2.
Benzoates
Derivatives of BENZOIC ACID. Included under this heading are a broad variety of acid forms, salts, esters, and amides that contain the carboxybenzene structure.
Polychlorinated Biphenyls
Industrial products consisting of a mixture of chlorinated biphenyl congeners and isomers. These compounds are highly lipophilic and tend to accumulate in fat stores of animals. Many of these compounds are considered toxic and potential environmental pollutants.
Oxygenases
Oxidases that specifically introduce DIOXYGEN-derived oxygen atoms into a variety of organic molecules.
Dioxygenases
Non-heme iron-containing enzymes that incorporate two atoms of OXYGEN into the substrate. They are important in biosynthesis of FLAVONOIDS; GIBBERELLINS; and HYOSCYAMINE; and for degradation of AROMATIC HYDROCARBONS.
