Methylhydroquinone is an intermediate in the degradation of fenitrothion by Burkholderia sp. NF100. The catabolic gene (mhq) for methylhydroquinone degradation encoded on the plasmid pNF1 in the strain was cloned and sequenced. The mhq clone contained two ORFs, mhqA and

Toluene-o-xylene monooxygenase (ToMO) from Pseudomonas stutzeri OX1 oxidizes toluene to 3- and 4-methylcatechol and oxidizes benzene to form phenol; in this study ToMO was found to also form catechol and 1,2,3-trihydroxybenzene (1,2,3-THB) from phenol. To synthesize novel dihydroxy and trihydroxy

The induction of mutagenic and cytotoxic effects by simple phenolics, including catechol (CAT), 3,4-dihydroxyphenylacetic acid (DOPAC), hydroquinone (HQ), and 2,5-dihydroxyphenylacetic (homogentisic) acid (HGA), appears to occur through an oxidative mechanism based on the ability of these compounds to undergo autoxidation

Recently, we showed that the MarR-type repressor YkvE (MhqR) regulates multiple dioxygenases/glyoxalases, oxidoreductases and the azoreductase encoding yvaB (azoR2) gene in response to thiol-specific stress conditions, such as diamide, catechol and 2-methylhydroquinone (MHQ). Here we report on the regulation of

A crude extract that catalyzes the epoxidation of toluquinol and gentisyl alcohol was isolated from cultures of Penicillium patulum. About 60% of the activity sedimented from crude extract upon centrifugation at 105,000g for 2 h, and at 30,000g for 30

Various polymeric oxidation products of polyphenols strongly inhibited the purified lipoxygenase of rabbit reticulocytes, whereas the prostaglandin H synthase of sheep vesicular gland was only weakly inhibited. The oxidized polymeric preparations of caffeic acid, 2,5-dihydroxytoluene and 3,4-dihydroxytoluene were the most

Bacillus subtilis is exposed to a variety of antimicrobial compounds in the soil. In this paper, we report on the response of B. subtilis to the fungal-related antimicrobials 6-brom-2-vinyl-chroman-4-on (chromanon) and 2-methylhydroquinone (2-MHQ) using proteome and transcriptome analyses. Chromanon, a

The dioxygenolytic catabolism of five C-methylated hydroquinones and 2,6-dichlorohydroquinone in Pseudomonas sp. strain HH35 was elucidated. This organism, which is known to catabolise 2,6-dimethylhydroquinone by 1,2-cleavage, accumulated metabolites from 2-methyl-, 2,3-dimethyl-, 2,5-dimethyl-, 2,3,5-trimethyl- and 2,3,5,6-tetramethylhydroquinone which we isolated and characterised

Catechol and 2-methylhydroquinone (2-MHQ) cause the induction of the thiol-specific stress response and four dioxygenases/glyoxalases in Bacillus subtilis. Using transcription factor arrays, the MarR-type regulator YkvE was identified as a repressor of the dioxygenase/glyoxalase-encoding mhqE gene. Transcriptional and proteome analyses

Recently, the concern that toluene might have carcinogenic and reproductive toxic potential has been raised. We investigated the ability of DNA damage by minor metabolites of toluene, methylhydroquinone, and methylbenzoquinone, using (32)P-5'-end-labeled DNA fragments obtained from the human genes. Methylhydroquinone

The possible tumor-promoting and tumor-initiating activities of p-methylcatechol and methylhydroquinone in the pyloric mucosa of male F344 rats were studied. Ornithine decarboxylase (ODC) and replicative DNA synthesis (RDS) were used as markers of tumor promotion and DNA single strand scission

Wild-type toluene 4-monooxygenase (T4MO) of Pseudomonas mendocina KR1 oxidizes toluene to p-cresol (96%) and oxidizes benzene sequentially to phenol, to catechol, and to 1,2,3-trihydroxybenzene. In this study T4MO was found to oxidize o-cresol to 3-methylcatechol (91%) and methylhydroquinone (9%), to

Toluquinol, a methylhydroquinone produced by a marine fungus, was selected in the course of a blind screening for new potential inhibitors of angiogenesis. In the present study we provide the first evidence that toluquinol is a new anti-angiogenic-compound. In a
