Gram-Negative Aerobic Rods and Cocci
A group of gram-negative bacteria consisting of rod- and coccus-shaped cells. They are both aerobic (able to grow under an air atmosphere) and microaerophilic (grow better in low concentrations of oxygen) under nitrogen-fixing conditions but, when supplied with a source of fixed nitrogen, they grow as aerobes.
Oxygenases
3-alpha-Hydroxysteroid Dehydrogenase (B-Specific)
A 3-hydroxysteroid dehydrogenase which catalyzes the reversible reduction of the active androgen, DIHYDROTESTOSTERONE to 5 ALPHA-ANDROSTANE-3 ALPHA,17 BETA-DIOL. It also has activity towards other 3-alpha-hydroxysteroids and on 9-, 11- and 15- hydroxyprostaglandins. The enzyme is B-specific in reference to the orientation of reduced NAD or NADPH.

Catechol 2,3-Dioxygenase
Catalyzes the oxidation of catechol to 2-hydroxymuconate semialdehyde in the carbazole and BENZOATE degradation via HYDROXYLATION pathways. It also catalyzes the conversion of 3-methylcatechol to cis, cis-2-hydroxy-6-oxohept-2,4-dienoate in the TOLUENE and XYLENE degradation pathway. This enzyme was formerly characterized as EC 1.13.1.2.
Alcohol Oxidoreductases
A subclass of enzymes which includes all dehydrogenases acting on primary and secondary alcohols as well as hemiacetals. They are further classified according to the acceptor which can be NAD+ or NADP+ (subclass 1.1.1), cytochrome (1.1.2), oxygen (1.1.3), quinone (1.1.5), or another acceptor (1.1.99).

Steroids
A group of polycyclic compounds closely related biochemically to TERPENES. They include cholesterol, numerous hormones, precursors of certain vitamins, bile acids, alcohols (STEROLS), and certain natural drugs and poisons. Steroids have a common nucleus, a fused, reduced 17-carbon atom ring system, cyclopentanoperhydrophenanthrene. Most steroids also have two methyl groups and an aliphatic side-chain attached to the nucleus. (From Hawley's Condensed Chemical Dictionary, 11th ed)

Oxidoreductases
The class of all enzymes catalyzing oxidoreduction reactions. The substrate that is oxidized is regarded as a hydrogen donor. The systematic name is based on donor:acceptor oxidoreductase. The recommended name will be dehydrogenase, wherever this is possible; as an alternative, reductase can be used. Oxidase is only used in cases where O2 is the acceptor.

Testosterone
A potent androgenic steroid and major product secreted by the LEYDIG CELLS of the TESTIS. Its production is stimulated by LUTEINIZING HORMONE from the PITUITARY GLAND. In turn, testosterone exerts feedback control of the pituitary LH and FSH secretion. Depending on the tissues, testosterone can be further converted to DIHYDROTESTOSTERONE or ESTRADIOL.
Genetic organization and characteristics of the 3-(3-hydroxyphenyl)propionic acid degradation pathway of Comamonas testosteroni TA441. (1/50)
Comamonas testosteroni TA441 degrades 3-(3-hydroxyphenyl)propionate (3HPP) via the meta pathway. A gene cluster required for degradation of 3HPP was cloned from strain TA441 and sequenced. The genes encoding six catabolic enzymes, a flavin-type hydroxylase (mhpA), extradiol dioxygenase (mhpB), 2-keto-4-pentenoate hydratase (mhpD), acetaldehyde dehydrogenase (acylating) (mhpF), 4-hydroxy-2-ketovalerate aldolase (mhpE) and the meta cleavage compound hydrolase (mhpC), were found in this cluster, encoded in this order. mhpD and mhpF were separated by two genes, orf4 and orf5, which were not necessary for growth on 3HPP. The gene mhpR, encoding a putative transcriptional activator of the IcIR family, was located adjacent to mhpA in the opposite orientation. Disruption of the mhpB or mhpR genes affected growth on 3HPP or trans-3-hydroxycinnamate. The mhpB and mhpC gene products showed high specificity for 3-(2,3-dihydroxyphenyl)propionate (DHPP) and the meta cleavage compound produced from DHPP, respectively. (+info)Crystal structure of delta(5)-3-ketosteroid isomerase from Pseudomonas testosteroni in complex with equilenin settles the correct hydrogen bonding scheme for transition state stabilization. (2/50)
Delta(5)-3-Ketosteroid isomerase from Pseudomonas testosteroni has been intensively studied as a prototype to understand an enzyme-catalyzed allylic isomerization. Asp(38) (pK(a) approximately 4.7) was identified as the general base abstracting the steroid C4beta proton (pK(a) approximately 12.7) to form a dienolate intermediate. A key and common enigmatic issue involved in the proton abstraction is the question of how the energy required for the unfavorable proton transfer can be provided at the active site of the enzyme and/or how the thermodynamic barrier can be drastically reduced. Answering this question has been hindered by the existence of two differently proposed enzyme reaction mechanisms. The 2.26 A crystal structure of the enzyme in complex with a reaction intermediate analogue equilenin reveals clearly that both the Tyr(14) OH and Asp(99) COOH provide direct hydrogen bonds to the oxyanion of equilenin. The result negates the catalytic dyad mechanism in which Asp(99) donates the hydrogen bond to Tyr(14), which in turn is hydrogen bonded to the steroid. A theoretical calculation also favors the doubly hydrogen-bonded system over the dyad system. Proton nuclear magnetic resonance analyses of several mutant enzymes indicate that the Tyr(14) OH forms a low barrier hydrogen bond with the dienolic oxyanion of the intermediate. (+info)Bioaugmentation of activated sludge by an indigenous 3-chloroaniline-degrading Comamonas testosteroni strain, I2gfp. (3/50)
A strain identified as Comamonas testosteroni I2 was isolated from activated sludge and found to be able to mineralize 3-chloroaniline (3-CA). During the mineralization, a yellow intermediate accumulated temporarily, due to the distal meta-cleavage of chlorocatechol. This strain was tested for its ability to clean wastewater containing 3-CA upon inoculation into activated sludge. To monitor its survival, the strain was chromosomally marked with the gfp gene and designated I2gfp. After inoculation into a lab-scale semicontinuous activated-sludge (SCAS) system, the inoculated strain maintained itself in the sludge for at least 45 days and was present in the sludge flocs. After an initial adaptation period of 6 days, complete degradation of 3-CA was obtained during 2 weeks, while no degradation at all occurred in the noninoculated control reactor. Upon further operation of the SCAS system, only 50% 3-CA removal was observed. Denaturing gradient gel electrophoresis (DGGE) of 16S rRNA genes revealed a dynamic change in the microbial community structure of the activated sludge. The DGGE patterns of the noninoculated and the inoculated reactors evolved after 7 days to different clusters, which suggests an effect of strain inoculation on the microbial community structure. The results indicate that bioaugmentation, even with a strain originating from that ecosystem and able to effectively grow on a selective substrate, is not permanent and will probably require regular resupplementation. (+info)Arrangement and regulation of the genes for meta-pathway enzymes required for degradation of phenol in Comamonas testosteroni TA441. (4/50)
Comamonas testosteroni TA441 degrades phenol by a meta-cleavage pathway after the occurrence of a spontaneous mutation that derepresses the aphKLMNOPQB operon encoding phenol hydroxylase and catechol 2,3-dioxygenase, the enzymes for the initial two steps of the degradation pathway. A gene cluster, aphCEFGHJI, encoding the meta-pathway enzymes for degradation of 2-hydroxymuconic semialdehyde (HMS) to TCA cycle intermediates was found downstream of the aphK operon. The upstream operon and the downstream gene cluster were found to be separated by two open reading frames of unknown function and an oppositely oriented aphT gene, which is similar to regulatory genes for ortho-cleavage of catechol or chlorinated catechols. A promoter assay using an aphC::lacZ transcriptional fusion plasmid revealed that the aphC promoter activity is induced by both phenol and HMS. The phenol-dependent induction was mediated by AphR and the HMS-dependent induction was mediated by AphT. The aphC promoter in strain TA441 was not silenced, unlike the cases of the aphK and aphR promoters, and was highly induced by HMS. (+info)Regulation of the steroid-inducible 3alpha-hydroxysteroid dehydrogenase/carbonyl reductase gene in Comamonas testosteroni. (5/50)
The Comamonas testosteroni 3alpha-hydroxysteroid dehydrogenase/carbonyl reductase gene (hsdA) codes for an adaptive enzyme in the degradation of steroid compounds. However, no information was available on the molecular regulation of steroid-inducible genes nor on the mechanism of steroid signaling in procaryotes. We, therefore, investigated the cis- and trans-acting elements of hsdA expression to infer the mechanism of its molecular regulation by steroids. The gene was localized on a 5.257-kilobase EcoRI fragment of C. testosteroni chromosomal DNA. The promoter was characterized, and the transcriptional start site was identified. Two palindromic operator domains were found upstream of hsdA. A new gene coding for a trans-acting negative regulator (repressor A, RepA) of hsdA expression was characterized. The specific interaction between RepA, testosterone, and the operator domain is demonstrated. From our results we conclude that hsdA is under negative transcriptional control by an adjacent gene product (RepA). Accordingly, induction of hsdA by steroids in fact is a derepression, where steroidal inducers bind to the repressor, thereby preventing its binding to the hsdA operator. (+info)Map of the IncP1beta plasmid pTSA encoding the widespread genes (tsa) for p-toluenesulfonate degradation in Comamonas testosteroni T-2. (6/50)
The catabolic IncP1beta plasmid pTSA from Comamonas testosteroni T-2 was mapped by subtractive analysis of restriction digests, by sequencing outwards from the tsa operon (toluenesulfonate degradation), and by generating overlapping, long-distance-PCR amplification products. The plasmid was estimated to comprise 72 +/- 4 kb. The tsa region was found to be a composite transposon flanked by two IS1071 elements. A cryptic tsa operon was also present in the tsa transposon. Those backbone genes and regions which we sequenced were in the same order as the corresponding genes in resistance plasmid R751, and identities of about 99% were observed. Enrichment cultures with samples from four continents were done to obtain organisms able to utilize p-toluenesulfonate as the sole source of carbon and energy for aerobic growth. Most (15) of the 16 cultures (13 of them isolates) were obtained from contaminated sites and were attributed to three metabolic groups, depending on their metabolism of p-toluenesulfonate. The largest group contained the tsa transposon, usually (six of seven isolates) with negligible differences in sequence from strain T-2. (+info)Endotoxic properties of lipid A from Comamonas testosteroni. (7/50)
The lipid A from Comamonas testosteroni has been isolated and its complete chemical structure determined [Iida, T., Haishima, Y., Tanaka, A., Nishijima, K., Saito, S. & Tanamoto, K. (1996). Eur J Biochem 237, 468-475]. In this work, the relationship between its chemical structure and biological activity was studied. The lipid A was highly homogeneous chemically and was characterized by the relatively short chain length (C(10)) of the 3-hydroxy fatty acid components directly bound to the glucosamine disaccharide backbone by either amide or ester linkages. The lipid A exhibited endotoxic activity in all of the assay systems tested (mitogenicity in mouse spleen cells; induction of tumour necrosis factor alpha release from both mouse peritoneal macrophages and mouse macrophage-like cell line J774-1, as well as from the human monocytic cell line THP-1; induction of nitric oxide release from J774-1 cells; Limulus gelation activity and lethal toxicity in galactosamine-sensitized mice) to the same extent as did 'Salmonella minnesota' lipid A or Escherichia coli LPS used as controls. The strong endotoxic activity of the C. testosteroni lipid A indicates that the composition of 3-hydroxydecanoic acid is not responsible for the low endotoxicity of the lipid A observed in members of the genus Rhodopseudomonas, as has previously been suggested. Furthermore, both the lack of a second acylation of the 3-hydroxy fatty acid attached at the 3' position, and the substitution of the hydroxyl group of the 3-hydroxy fatty acid attached at position 2, do not affect the manifestation of endotoxic activity or species specificity. (+info)PhcS represses gratuitous expression of phenol-metabolizing enzymes in Comamonas testosteroni R5. (8/50)
We identified an open reading frame, designated phcS, downstream of the transcriptional activator gene (phcR) for the expression of multicomponent phenol hydroxylase (mPH) in Comamonas testosteroni R5. The deduced product of phcS was homologous to AphS of C. testosteroni TA441, which belongs to the GntR family of transcriptional regulators. The transformation of Pseudomonas aeruginosa PAO1c (phenol negative, catechol positive) with pROR502 containing phcR and the mPH genes conferred the ability to grow on phenol, while transformation with pROR504 containing phcS, phcR, and mPH genes did not confer this ability. The disruption of phcS in strain R5 had no effect on its phenol-oxygenating activity in a chemostat culture with phenol. The phenol-oxygenating activity was not expressed in strain R5 grown in a chemostat with acetate. In contrast, the phenol-oxygenating activity in the strain with a knockout phcS gene when grown in a chemostat with acetate as the limiting growth factor was 66% of that obtained in phenol-grown cells of the strain with a knockout in the phcS gene. The disruption of phcS and/or phcR and the complementation in trans of these defects confirm that PhcS is a trans-acting repressor and that the unfavorable expression of mPH in the phcS knockout cells grown on acetate requires PhcR. These results show that the PhcS protein repressed the gratuitous expression of phenol-metabolizing enzymes in the absence of the genuine substrate and that strain R5 acted by an unknown mechanism in which the PhcS-mediated repression was overcome in the presence of the pathway substrate.
