dc.description.abstract | 2,3-Dihydroxybiphenyl 1,2-dioxygenase (2,3-DHBD), which catalyzes the ring meta-cleavage of 2,3dihydroxybiphenyl, is encoded by the phnQ gene of biphenyl- and phenanthrene-degrading Pseudomonas sp, strain DJ77, We determined the nucleotide sequence of a DNA fragment of 1497 base pairs which included the phnQ gene. The fragment included an open reading frame of 903 base pairs to accommodate the enzyme. The predicted amino acid sequence of the enzyme subunit consisted of 300 residues. In front of the gene, a sequence resembling an E. coli promoter was identified, which led to constitutive expression of the cloned gene in E. coli, The deduced amino acid sequence of the PhnQ enzyme exhibited 85.6% identity with that of the corresponding enzyme in Sphingomonas yanoikuyae Q1 (formerly S, paucimobilis Q1) and 22.1% identity with that of catechol 1,2,3-dioxygenase from the same DJ77 strain. PhnQ showed broader substrate preference than previously-cloned PhnE, catechol 2,3-dioxygenase. Ten amino acid residues, considered to be important for the role of extradiol dioxygenases, were conserved. | - |
