Specific activities of Catechol-2,3-dioxygenase and effects of temperature and pH and their stabilities on the enzyme relative activities were observed. (openmicrobiologyjournal.com)
The enzyme is resistant to denaturation by various chelators and inhibitors (EDTA, 1,10-phenanthroline, H2O2, 3-chlorocatechol) and did not exhibit substrate inhibition even at 3 mM 2,3-dihydroxybiphenyl. (muni.cz)
A 3-D homology model of BphC_JF8 provided a basis for understanding the substrate specificity, quaternary structure and stability of the enzyme. (muni.cz)
PAHs could be degraded by bacteria under aerobic conditions through the initial oxidation of the aromatic ring, which is catalyzed by the dioxygenase enzyme. (omicsonline.org)

Cleavage3
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. (muni.cz)

Catechol 2,3-dioxygenase (C23O) gene was found andamplified with the designed primers from the total DNA of C-14-1. (researchgate.net)
Moreover, a dioxygenase gene, nidA3B3, was detected in Mycobacterium vanbaalenii PYR-1 as an alternate degradation pathway which could catalyze both the initial dihydroxylation of pyrene [ 11 ] to be pyrene cis-4,5-dihydrodiol, and an alternate detoxification pyrene pathway to be pyrene cis-1,2-dihydrodiol [ 12 ].

Pathway1
The pcaH was significant in the β-ketoadipate pathway [9] where the pathway as it conserves biochemically, and is a major class of non-heme-iron containing dioxygenase [ 10 ]. (omicsonline.org)
Enzymes1
The metal ligands and active site residues of extradiol dioxygenases are conserved although several amino acid residues found exclusively in enzymes which preferentially cleave bicyclic substrates are missing in BphC_JF8. (muni.cz)
Temperature1
A decrease in Km accompanied an increase in temperature and the Km value of 0.095 uM for 2,3-dihydroxybiphenyl (at 60 C) is among the lowest reported. (muni.cz)
