Extradiol cleavage of 3-methylcatechol by catechol 1,2-dioxygenase from various microorganisms.
نویسندگان
چکیده
The isofunctional enzymes of catechol 1,2-dioxygenase from species of Acinetobacter, Pseudomonas, Nocardia, Alcaligenes, and Corynebacterium oxidize 3-methylcatechol according to both the intradiol and extradiol cleavage patterns. However, the enzyme preparations from Brevibacterium and Arthrobacter have only the intradiol cleavage activity. Comparison of substrate specificity among these isofunctional dioxygenases shows striking differences in the oxidation of 3-methylcatechol, 4-methylcatechol and pyrogallol.

Analysis of a new dimeric extradiol dioxygenase from a naphthalenesulfonate-degrading sphingomonad.
A new extradiol dioxygenase was cloned by screening a gene bank from the naphthalenesulfonate-degrading bacterial strain BN6 for colonies with 2,3-dihydroxybiphenyl dioxygenase (DHBPDO) activity. A 1.6 kb DNA fragment was sequenced and an ORF of 954 bp identified. Comparison of the deduced amino acid sequence of DHBPDO II from strain BN6 with previously published sequences showed the closest re...
متن کاملCharacterization of catechol 2,3-dioxygenase from Planococcus sp. strain S5 induced by high phenol concentration.
This study aimed at characterization of a new catechol 2,3-dioxygenase isolated from a Gram-positive bacterium able to utilize phenol as the sole carbon and energy source. Planococcus sp. strain S5 grown on 1 or 2 mM phenol showed activity of both a catechol 1,2- and catechol 2,3-dioxygenase while at a higher concentrations of phenol only catechol 2,3-dioxygenase activity was observed. The enzy...
متن کاملCharacterization of 2,2',3-trihydroxybiphenyl dioxygenase, an extradiol dioxygenase from the dibenzofuran- and dibenzo-p-dioxin-degrading bacterium Sphingomonas sp. strain RW1.
A key enzyme in the degradation pathways of dibenzo-p-dioxin and dibenzofuran, namely, 2,2',3-trihydroxybiphenyl dioxygenase, which is responsible for meta cleavage of the first aromatic ring, has been genetically and biochemically analyzed. The dbfB gene of this enzyme has been cloned from a cosmid library of the dibenzo-p-dioxin- and dibenzofuran-degrading bacterium Sphingomonas sp. strain RW...
متن کاملConversion of 3-chlorocatechol by various catechol 2,3-dioxygenases and sequence analysis of the chlorocatechol dioxygenase region of Pseudomonas putida GJ31.
Pseudomonas putida GJ31 contains an unusual catechol 2,3-dioxygenase that converts 3-chlorocatechol and 3-methylcatechol, which enables the organism to use both chloroaromatics and methylaromatics for growth. A 3.1-kb region of genomic DNA of strain GJ31 containing the gene for this chlorocatechol 2,3-dioxygenase (cbzE) was cloned and sequenced. The cbzE gene appeared to be plasmid localized an...
متن کاملCharacterization of a novel thermostable Mn(II)-dependent 2,3-dihydroxybiphenyl 1,2-dioxygenase from a polychlorinated biphenyl- and naphthalene-degrading Bacillus sp. JF8.
A novel thermostable Mn(II)-dependent 2,3-dihydroxybiphenyl-1,2-dioxygenase (BphC_JF8) catalyzing the meta-cleavage of the hydroxylated biphenyl ring was purified from the thermophilic biphenyl and naphthalene degrader, Bacillus sp. JF8, and the gene was cloned. The native and recombinant BphC enzyme was purified to homogeneity. The enzyme has a molecular mass of 125 +/- 10 kDa and was composed...
