Anthranilate is an aromatic amine used industrially as an intermediate for the synthesis of dyes, perfumes, pharmaceuticals and other classes of products. Chemical synthesis of anthranilate is an unsustainable process since it implies the use of nonrenewable benzene and the generation of toxic by-products. In Escherichia coli anthranilate is synthesized from chorismate by anthranilate synthase (TrpED) and then converted to phosphoribosyl anthranilate by anthranilate phosphoribosyl transferase to continue the tryptophan biosynthetic pathway. With the purpose of generating a microbial strain for anthranilate production from glucose, E. coli W3110 trpD9923, a mutant in the trpD gene that displays low anthranilate producing capacity, was characterized and modified using metabolic engineering strategies. Sequencing of the trpED genes from E. coli W3110 trpD9923 revealed a nonsense mutation in the trpD gene, causing the loss of anthranilate phosphoribosyl transferase activity, but maintaining anthranilate
Catalyzes the dehydrogenation of acyl-coenzymes A (acyl-CoAs) to 2-enoyl-CoAs, the first step of the beta-oxidation cycle of fatty acid degradation. Is required for S.typhimurium to utilize medium- and long-chain fatty acids as sole carbon sources for growth. Is needed for bacterial survival during carbone-source starvation.
Catalyzes the ATP-dependent amidation of the two carboxylate groups at positions a and c of cobyrinate, using either L-glutamine or ammonia as the nitrogen source. Is able to use other nucleotide triphosphates as substrate, such as GTP or UTP, although less efficiently than ATP.

Virulent Salmonella typhimurium strains differ from the attenuated laboratory strain LT2 at the rpoS locus. It was previously shown that the rpoS gene in strain LT2 contains a rare UUG start codon (I. S. Lee, J. Lin, H. K. Hall, B. Bearson, and J. W. Foster, Mol. Microbiol. 17:155-167, 1995). This difference is responsible for the inability of LT2 to display a sustained log-phase acid tolerance response. We show that the altered rpoS allele (rpoS(LT2)) also affects the stationary-phase acid tolerance response in Salmonella. By transducing the rpoS(LT2) allele into virulent strain backgrounds and crossing wild-type rpoS allele into strain LT2, we demonstrate that the rpoS(LT2) allele contributes to the attenuation of strain LT2. We examined the effect of the rpoS allele on invasion and found that the rpoS status of the cell had no effect on the ability of the strains to invade intestinal epithelial cells in tissue culture. Enumeration of bacteria from tissues of infected mice indicated that the ...

PQS biosynthetic functions of several of the pqs products are suggested by their sequence homologies (Fig. 4). PhnA and PhnB presumably synthesize the anthranilate precursor of PQS from chorismate (4, 10). Gene pqsA encodes a product homologous to benzoate coenzyme A ligase, which may be involved in activating anthranilate for PQS synthesis. Genes pqsB, pqsC, and pqsD encode proteins homologous to β-keto-acyl-acyl carrier protein synthases and are presumably involved in the production of a long chain hydrocarbon which reacts with anthranilate in the PQS biosynthetic pathway (4). Gene pqsE is not homologous to any defined proteins and our results indicate that it is not required for PQS synthesis. Gene pqsH encodes a putative FAD-dependent monooxygenase that may be responsible for the addition of the hydroxyl group to PQS.. Although phnA and phnB were originally assumed to encode an anthranilate synthetase comprising part of the phenazine biosynthetic pathway (10), recent studies by Mavrodi et ...

1. The formation of adenosine 5-phosphate, guanosine 5-phosphate and inosine 5-phosphate from [8-(14)C]adenine, [8-(14)C]guanine and [8-(14)C]hypoxanthine respectively in the presence of 5-phosphoribosyl pyrophosphate and an extract from Ehrlich ascites-tumour cells was assayed by a method involving liquid-scintillation counting of the radioactive nucleotides on diethylaminoethylcellulose paper. The results obtained with guanine were confirmed by a spectrophotometric assay which was also used to assay the conversion of 6-mercaptopurine and 5-phosphoribosyl pyrophosphate into 6-thioinosine 5-phosphate in the presence of 6-mercaptopurine phosphoribosyltransferase from these cells. 2. At pH 7.8 and 25 degrees the Michaelis constants for adenine, guanine and hypoxanthine were 0.9 mum, 2.9 mum and 11.0 mum in the assay with radioactive purines; the Michaelis constant for guanine in the spectrophotometric assay was 2.6 mum. At pH 7.9 the Michaelis constant for 6-mercaptopurine was 10.9 mum. 3. 25 mum-6

AU - Seo, Jin Ho. PY - 2019/3/1. Y1 - 2019/3/1. N2 - Numerous metabolic engineering strategies have allowed yeasts to efficiently assimilate xylose, the second most abundant sugar component of lignocellulosic biomass. During the investigation of xylose utilization by yeasts, a global rewiring of metabolic networks upon xylose cultivation has been captured, as opposed to a pattern of glucose repression. A clear understanding of the xylose-induced metabolic reprogramming in yeast would shed light on the optimization of yeast-based bioprocesses to produce biofuels and chemicals using xylose. In this review, we delved into the characteristics of yeast xylose metabolism, and potential benefits of using xylose as a carbon source to produce various biochemicals with examples. Transcriptomic and metabolomic patterns of ...
Sodium Dodecyl Sulfate, or SDS, is an anionic detergent with widespread use in industrial and household cleaning products, scientific laboratories, and personal care products such as toothpaste and shampoo. The potential toxicity of SDS has been well-characterized in whole organism studies and its potential effects on the environment continue to be studied. Herein, we undertake a chemical-genetic screen to explore whether low concentrations of SDS have any discernible effects at the cellular level. Our screen of the homozygous diploid yeast deletion collection identified numerous gene deletions that confer sensitivity to SDS. Subsequent bioinformatic and biological analyses reveal that yeast unable to synthesize tryptophan are especially sensitive to the presence of SDS. Interestingly, even wild-type yeast with an intact tryptophan biosynthetic pathway exhibit growth defects in the presence of SDS on media lacking tryptophan. Altogether, we have shown that low levels of SDS, primarily through ...

Mycobacteria tuberculosis (Mtb), the causative agent of tuberculosis, is responsible for more death in the world today than any other bacteria. As part of the Tuberculosis Structural Genomics Consortium (TBSGC), our research group previously determined the structure of anthranilate phosphoribosyl transferase (AnPRT) from Mtb. AnPRT is the second enzyme in the tryptophan biosynthetic pathway and was identified as a potential drug target through gene knockout experiments, which resulted in a strain of Mtb that was essentially avirulent even in immunodeficient mice. AnPRT catalyses a reaction between anthranilate and phosphoribosylpyrophosphate (PRPP), and the crystal structure of Mtb-AnPRT was originally determined with and without PRPP (PDB ID: 1ZVW and 2BPQ, respectively). In silico docking was used to predict the binding motif of anthranilate, the second substrate, surprisingly predicted two sites despite a 1:1 reaction ratio with PRPP. Previously, 165 compounds were screened for inhibitory ...

Purine phosphoribosyltransferases, purine PRTs, are essential enzymes in the purine salvage pathway of living organisms. They are involved in the formation of C-N glycosidic bonds in purine nucleosides-50-monophosphate (NMPs) through the transfer of the 5-phosphoribosyl group from 5-phospho-a-D-ribosyl-1-pyrophosphate (PRPP) to purine nucleobases in the presence of Mg2þ. Herein, we report a simple and thermostable process for the one-pot, one-step synthesis of some purine NMPs using xanthine phosphoribosyltransferase, XPRT or adenine phosphoribosyltransferase, APRT2, from Thermus thermophilus HB8. In this sense, the cloning, expression and purification of TtXPRT and TtAPRT2 is described for the first time. Both genes, xprt and aprt2 were expressed as his-tagged enzymes in E. coli BL21(DE3) and purified by a heat-shock treatment, followed by Ni-affinity chromatography and a final, polishing gel-filtration chromatography. Biochemical characterization revealed TtXPRT as a tetramer and TtAPRT2 as a ...
