Bacteria in anoxic environments typically convert aromatic compounds derived from pollutants or green plants to benzoyl-CoA, and then to the C7 dicarboxylic acid derivative 3-hydroxypimelyl-CoA. Inspection of the recently completed genome sequence of the purple nonsulfur phototroph Rhodopseudomonas palustris revealed one predicted cluster of genes for the beta-oxidation of dicarboxylic acids. These genes, annotated as pimFABCDE, are predicted to encode acyl-CoA ligase, enoyl-CoA hydratase, acyl…

Decarboxylating and Nondecarboxylating Glutaryl-Coenzyme A Dehydrogenases in the Aromatic Metabolism of Obligately Anaerobic Bacteria

Highly conserved amino acid residues that were proposed to be specifically involved in the decarboxylation of the intermediate glutaconyl-CoA were identified inGDH(Geo) but are missing in GDH(Des), and the differential use of energy-yielding/energy-demanding enzymatic processes in anaerobic bacteria that degrade aromatic compounds is discussed.

Small-Molecule Acetylation Controls the Degradation of Benzoate and Photosynthesis in Rhodopseudomonas palustris

This work shows that the BadL protein of Rhodopseudomonas palustris has N-acetyltransferase activity and that this activity is required for the catabolism of benzoate under photosynthetic conditions…

Insights into the Degradation of Medium-Chain-Length Dicarboxylic Acids in Cupriavidus necator H16 Reveal β-Oxidation Differences between Dicarboxylic Acids and Fatty Acids

The biotechnologically interesting bacterium Cupriavidus necator H16 was investigated and showed differences from the degradation of hexanoic acid, and two operons involved in growth with long-chain fatty acids seem to be replaced during growth on medium-chain carboxylic acids.

Transfer of the high-GC cyclohexane carboxylate degradation pathway from Rhodopseudomonas palustris to Escherichia coli for production of biotin.

BadR and BadM Proteins Transcriptionally Regulate Two Operons Needed for Anaerobic Benzoate Degradation by Rhodopseudomonas palustris

It is shown that the MarR transcription factor family member, BadR, represses transcription of the CHC operon by binding near the transcription start site of badH, which enhances the view of the transcriptional regulation of anaerobic benzoate degradation by R. palustris.

Anaerobic degradation of aromatic amino acids by the hyperthermophilic archaeon Ferroglobus placidus.

The results suggested that the general strategies for anaerobic degradation of aromatic amino acids are highly conserved amongst bacteria and archaea living in both mesophilic and hyperthermophilic environments.

Tetralin-Induced and ThnR-Regulated Aldehyde Dehydrogenase and β-Oxidation Genes in Sphingomonas macrogolitabida Strain TFA

Transcriptional analysis indicated that these genes are induced by tetralin, subjected to catabolite repression, and regulated by the same regulatory factors previously identified to regulate other thn structural genes.

Characterization of Anaerobic Catabolism of p-Coumarate in Rhodopseudomonas palustris by Integrating Transcriptomics and Quantitative Proteomics*S

The integrated gene expression data provided strong support for the non-β-oxidation route in R. palustris, consistent with the hypothesis that p-coumarate is converted to benzoyl-CoA, which is then degraded via a known aromatic ring reduction pathway.

A synthetic bad-ali-aab catabolic module was engineered and it was shown to confer CHC degradation abilities to different bacterial hosts.

This work provides presumptive evidnce that Pseudomonas fluorescens metabolizes the higher homologs (C6 to C10) of the saturated dicarboxylic acid series by β-oxidation, mediated by a specific series…

BadR, a New MarR Family Member, Regulates Anaerobic Benzoate Degradation by Rhodopseudomonas palustris in Concert with AadR, an Fnr Family Member

These studies expand the range of functions regulated by MarR family members to include anaerobic aromatic acid degradation and provide an example of a MarR-type protein that acts as a positive regulator rather than as a negative regulator, as do most MarRfamily members.

Anaerobic degradation of pimelate by newly isolated denitrifying bacteria.

Glutaryl-CoA dehydrogenase and glutaconyl- CoA decarboxylase activities were expressed in cells grown with pimelate or benzoate, indicating the specific involvement of these enzyme activities in anaerobic degradation of these two acids.

Purification and properties of benzoate-coenzyme A ligase, a Rhodopseudomonas palustris enzyme involved in the anaerobic degradation of benzoate

The kinetic properties of the enzyme match the kinetics of substrate uptake by whole cells and confirm a role for benzoate-CoA ligase in maintaining entry of Benzoate into cells as well as in catalyzing the first step in the anaerobic degradation of benzoates by R. palustris.

Cloning and Genetic Characterization of dca Genes Required for β-Oxidation of Straight-Chain Dicarboxylic Acids in Acinetobacter sp. Strain ADP1

Because the mutants were affected in their ability to utilize additional saturated, straight-chain dicarboxylic acids, the newly discovered 10 kb of DNA was termed the dca region which should help probe the functional significance and interrelationships of clustered genetic elements in this section of the Acinetobacterchromosome.

Benzoate-coenzyme A ligase, encoded by badA, is one of three ligases able to catalyze benzoyl-coenzyme A formation during anaerobic growth of Rhodopseudomonas palustris on benzoate

Results show that wild-type R. palustris cells synthesize at least three enzymes that can catalyze the initial step in anaerobic benzoate degradation during growth on benzoates, and supports previous suggestions that benzoyl-coenzyme A formation plays a central role in an aerobic aromatic compound biodegradation.

Evidence that the fadB gene of the fadAB operon of Escherichia coli encodes 3-hydroxyacyl-coenzyme A (CoA) epimerase, delta 3-cis-delta 2-trans-enoyl-CoA isomerase, and enoyl-CoA hydratase in addition to 3-hydroxyacyl-CoA dehydrogenase

Findings support the suggestion that the epimerase and isomerase as well as enoyl-CoA hydratase and L-3-hydroxyacyl- coenzyme A dehydrogenase are located on the same polypeptide.

Energetics and biochemistry of fermentative benzoate degradation by Syntrophus gentianae

The pathway of fermentative benzoate degradation by the syntrophically fermenting bacterium Syntrophus gentianae was studied by measurement of enzyme activities in cell-free extracts and can be balanced to yield one-third to two-thirds of an ATP unit per Benzoate degraded, in accordance with earlier measurements of whole-cell energetics.

The pimeloyl-CoA synthase from Bacillus sphaericus has been purified to homogeneity from an overproducing strain of Escherichia coli and N-Terminal sequencing definitely proved that this enzyme was encoded by the bioW gene.

Purification of glutaryl-CoA dehydrogenase from Pseudomonas sp., an enzyme involved in the anaerobic degradation of benzoate

Cell-free extracts of Pseudomonas strains KB 740 and K 172 both contained high levels of glutaryl-CoA dehydrogenase when grown anaerobically on benzoate or other aromatic compounds and with nitrate as electron acceptor, and an about equally high glutaconyl- CoA decarboxylase activity was detected in cell- free extracts.
