The three genes encoding the 4-chlorobenzene dehalogenase polypeptides were excised from a Pseudomonas sp. CBS-3 DNA fragment and separately cloned and expressed in Escherichia coli. The three enzymes were purified from the respective subclones by using an ammonium sulfate precipitation step followed by one or two column chromatographic steps. The 4-chlorobenzoate:coenzyme A ligase was found to be a homodimer (57-kDa subunit size), to require Mg2+ (Co2+ and Mn2+ are also activators) for activity, and to turn over MgATP (Km = 100 microM), coenzyme A (Km = 80 microM), and 4-chlorobenzoate (Km = 9 microM) at a rate of 30 s-1 at pH 7.5 and 25 degrees C. Benzoate, 4-bromobenzoate, 4-iodobenzoate, and 4-methylbenzoate were shown to be alternate substrates while 4-hydroxybenzoate, 4-aminobenzoate, 2-aminobenzoate, 2,3-dihydroxybenzoate, 4-coumarate, palmate, laurate, caproate, butyrate, and phenylacetate were not substrate active. The 4-chlorobenzoate-coenzyme A dehalogenase was found to be a homotetramer (30 kDa subunit size) to have a Km = 15 microM and kcat = 0.3 s-1 at pH 7.5 and 25 degrees C and to be catalytically inactive toward hydration of crotonyl-CoA, alpha-methylcrotonyl-CoA, and beta-methylcrotonyl-CoA. The 4-hydroxybenzoate-coenzyme A thioesterase was shown to be a homotetramer (16 kDa subunit size), to have a Km = 5 microM and kcat = 7 s-1 at pH 7.5 and 25 degrees C, and to also catalyze the hydrolyses of benzoyl-coenzyme A and 4-chlorobenzoate-coenzyme A. Acetyl-coenzyme A, hexanoyl-coenzyme A, and palmitoyl-coenzyme A were not hydrolyzed by the thioesterase. << Less

Characterization of the 4-hydroxybenzoyl-coenzyme A thioesterase from Arthrobacter sp. strain SU.
Zhuang Z., Gartemann K.H., Eichenlaub R., Dunaway-Mariano D.
The Arthrobacter sp. strain SU 4-chlorobenzoate (4-CBA) dehalogenation pathway converts 4-CBA to 4-hydroxybenzoate (4-HBA). The pathway operon contains the genes fcbA, fcbB, and fcbC (A. Schmitz, K. H. Gartemann, J. Fiedler, E. Grund, and R. Eichenlaub, Appl. Environ. Microbiol. 58:4068-4071, 1992 ... >> More
The Arthrobacter sp. strain SU 4-chlorobenzoate (4-CBA) dehalogenation pathway converts 4-CBA to 4-hydroxybenzoate (4-HBA). The pathway operon contains the genes fcbA, fcbB, and fcbC (A. Schmitz, K. H. Gartemann, J. Fiedler, E. Grund, and R. Eichenlaub, Appl. Environ. Microbiol. 58:4068-4071, 1992). Genes fcbA and fcbB encode 4-CBA-coenzyme A (CoA) ligase and 4-CBA-CoA dehalogenase, respectively, whereas the function of fcbC is not known. We subcloned fcbC and expressed it in Escherichia coli, and we purified and characterized the FcbC protein. A substrate activity screen identified benzoyl-CoA thioesters as the most active substrates. Catalysis of 4-HBA-CoA hydrolysis to 4-HBA and CoA occurred with a k(cat) of 6.7 s(-1) and a K(m) of 1.2 micro M. The k(cat) pH rate profile for 4-HBA-CoA hydrolysis indicated optimal activity over a pH range of 6 to 10. The amino acid sequence of the FcbC protein was compared to other sequences contained in the protein sequence data banks. A large number of sequence homologues of unknown function were identified. On the other hand, the 4-HBA-CoA thioesterases isolated from 4-CBA-degrading Pseudomonas strains did not share significant sequence identity with the FcbC protein, indicating early divergence of the thioesterase-encoding genes. << Less

This review examines the enzymes of 4-chlorobenzoate to 4-hydroxybenzoate converting pathway found in certain soil bacteria. This pathway consists of three enzymes: 4-chlorobenzoate: Coenzyme A ligase, 4-chlorobenzoyl-Coenzyme A dehalogenase and 4-hydroxybenzoyl-Coenzyme A thioesterase. Recent progress made in the cloning and expression of the pathway genes from assorted bacterial strains is described. Gene order and sequence found among these strains are compared to reveal independent enzyme recruitment strategies. Sequence alignments made between the Pseudomonas sp. strain CBS3 4-chlorobenzoate pathway enzymes and structurally related proteins contained within the protein sequence data banks suggest possible origins in preexisting beta-oxidation pathways. The purification and characterization of the physical and kinetic properties of the pathway enzymes are described. Where possible a comparison of these properties between like enzymes from different bacterial sources are made. << Less
