Journal ArticleDOI
The evolution of pathways for aromatic hydrocarbon oxidation in Pseudomonas
Peter A. Williams,Jon R. Sayers +1 more
TL;DR: The organisation and nucleotide sequences coding for the catabolism of benzene, toluene, naphthalene and biphenylvia catechol and the extradiol (meta) cleavage pathway in Pseudomonas are reviewed and the data suggests that the complete pathways have evolved in a modular way probably from at least three elements.
Journal ArticleDOI
A Gene Cluster Encoding Steps in Conversion of Naphthalene to Gentisate in Pseudomonas sp. Strain U2
TL;DR: Recombinant Escherichia coli strains with plasmids carrying this region were able to convert salicylate to gentisate, which was identified by a combination of gas chromatography-mass spectrometry and nuclear magnetic resonance.
Journal ArticleDOI
nag genes of Ralstonia (formerly Pseudomonas) sp. strain U2 encoding enzymes for gentisate catabolism.
TL;DR: By cloning into expression vectors and by biochemical assays, three of these genes (nagIKL) have been shown to encode the enzymes involved in the further catabolism of gentisate to fumarate and pyruvate.
Journal ArticleDOI
Complete sequence of the IncP-9 TOL plasmid pWW0 from Pseudomonas putida.
TL;DR: The pWW0 replicon and stable inheritance region was very similar to the mini-replicon from IncP-9 antibiotic resistance plasmid pM3, with their Rep proteins forming a novel group of initiation proteins.
Journal ArticleDOI
Two modes of loss of the Tol function from Pseudomonas putida mt-2.
Susan A. Bayley,Clive J. Duggleby,Michael J. Worsey,Peter A. Williams,Kimber G. Hardy,Paul Broda +5 more
TL;DR: Some of a set of independently arising Tol- (non toluate-utilising) derivatives of Pseudomonas putida mt-2 have lost the unique plasmid present in the parent strain.
