Int J Biol Macromol 2024; 278:134858. [PMID: 39163968 DOI: 10.1016/j.ijbiomac.2024.134858] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2024] [Revised: 08/12/2024] [Accepted: 08/17/2024] [Indexed: 08/22/2024]
Abstract
The iminosugar class of carbohydrate-active enzyme inhibitors has therapeutic applications in metabolic syndrome conditions, viral infections and cancer. Compared to chemical synthesis, microbial iminosugar production has benefits of cost, sustainability and optimization. In this study, the 1-deoxynojirimycin (DNJ) biosynthetic gene cluster from Bacillus velezensis MBLB0692, and its individual genes, were cloned into Corynebacterium glutamicum (Cg). Characterizations of the encoded aminotransferase GabT1, phosphatase Yktc1, and dehydrogenase GutB1, were performed with purified enzymes and whole cell biocatalysts bearing individual and clustered (TYB) genes. GabT1 showed a variable pattern in its half-reaction with a slow turnover. GutB1 was an alkaline dehydrogenase with a broad substrate specificity and no divalent ion dependency while the zinc-dependent phosphatase Yktc1 had substrate specificity that was both pH- and ion-dependent. The CgYktc1 and CgGutB1 whole cells were viable biocatalysts with wider ranges of substrates than their enzyme counterparts. The CgTYB cells produced mannosidase-inhibiting iminosugars corresponding to mannojirimycin dehydrate (162 m/z) and deoxymannojirimycin (164 m/z). Mannosidase inhibitors have been found to be effective in treating orphan diseases, cancer and viral infections, and their biosynthesis by recombinant C. glutamicum can be optimized for industrial production and novel drug development.

Abstract
Dendrobium officinale is a precious Chinese medicinal plant that is rich in polysaccharides, flavonoids, polyphenols, and other bioactive ingredients, and has a variety of biological activities. To explore the effects of D. officinale on the growth and metabolism of Saccharomyces cerevisiae, different concentrations (0, 10, 30, 50, and 100 g/L) of fresh D. officinale were added to the wort during the fermentation. The amount of yeast, alcohol content, reducing sugars, total acidity, pH, CO2 loss, and foam height were analyzed. Meanwhile, the glucose uptake, cell viability, key enzyme activity of yeast, total phenolics, antioxidant activity, volatile compounds, and consumer acceptance of brewed samples were also analyzed. The results showed that the growth and metabolism of yeast could be promoted by a suitable dosage of D. officinale but were inhibited at high dosage (100 g/L). The addition of D. officinale increased the activities of glucose-6-phosphate dehydrogenase and alcohol dehydrogenase, while the highest concentration of D. officinale (100 g/L) decreased the glucose uptake and cell activity of the yeast. The contents of total phenolics and esters, along with the scavenging activity against ABTS radicals, were increased, indicating that the antioxidant activity and aromatic characteristics of beer would be improved by the addition of D. officinale.

J Microbiol Biotechnol 2022; 32:1054-1063. [PMID: 35791071 PMCID: PMC9628947 DOI: 10.4014/jmb.2202.02028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2022] [Revised: 05/09/2022] [Accepted: 05/13/2022] [Indexed: 12/15/2022]
Abstract
Trehalose is a non-conventional sugar with potent applications in the food, healthcare and biopharma industries. In this study, trehalose was synthesized from maltose using whole-cell Pseudomonas monteilii TBRC 1196 producing trehalose synthase (TreS) as the biocatalyst. The reaction condition was optimized using 1% Triton X-100 permeabilized cells. According to our central composite design (CCD) experiment, the optimal process was achieved at 35°C and pH 8.0 for 24 h, resulting in the maximum trehalose yield of 51.60 g/g after 12 h using an initial cell loading of 94 g/l. Scale-up production in a lab-scale bioreactor led to the final trehalose concentration of 51.91 g/l with a yield of 51.60 g/g and productivity of 4.37 g/l/h together with 8.24 g/l glucose as a byproduct. A one-pot process integrating trehalose production and byproduct bioremoval showed 53.35% trehalose yield from 107.4 g/l after 15 h by permeabilized P. moteilii cells. The residual maltose and glucose were subsequently removed by Saccharomyces cerevisiae TBRC 12153, resulting in trehalose recovery of 99.23% with 24.85 g/l ethanol obtained as a co-product. The present work provides an integrated alternative process for trehalose production from maltose syrup in bio-industry.

Synthesis of natural variants and synthetic derivatives of the cyclic nonribosomal peptide luminmide in permeabilized E. coli Nissle and product formation kinetics. Appl Microbiol Biotechnol 2016; 101:131-138.

Abstract
We used a recombinant, permeabilized E. coli Nissle strain harbouring the plu3263 gene cluster from Photorhabdus luminescens for the synthesis of luminmide type cyclic pentapeptides belonging to the class of nonribosomally biosynthesized peptides (NRP). Cells could be fully permeabilized using 1 % v/v toluene. Synthesis of luminmides was increased fivefold when 0.3 mM EDTA was added to the substrate mixture acting as an inhibitor of metal proteases. Luminmide formation was studied applying different amino acid concentrations. Apparent kinetic parameters for the synthesis of the main product luminmide A from leucine, phenylalanine and valine were calculated from the collected data. K sapp values ranged from 0.17 mM for leucine to 0.57 mM for phenylalanine, and r maxapp was about 3 × 10-8 mmol min-1(g CDW)-1). By removing phenylalanine from the substrate mixture, the formation of luminmide A was reduced tenfold while luminmide B was increased from 50 to 500 μg/l becoming the main product. Two new luminmides were synthesized in this study. Luminmide H incorporates tryptophan replacing phenylalanine in luminmide A. In luminmide I, leucine was replaced with 4,5-dehydro-leucine, a non-proteinogenic amino acid fed to the incubation mixture. Our study shows new opportunities for increasing the spectrum of luminmide variants produced, for improving production selectivity and for kinetic in vitro studies of the megasynthetases.

Abstract
: Recent developments in the field of biocatalysis using permeabilized cells are reviewed here, with a special emphasis on the newly emerging area of multistep biocatalysis using permeabilized cells. New methods of metabolic engineering using in silico network design and new methods of genetic engineering provide the opportunity to design more complex biocatalysts for the synthesis of complex biomolecules. Methods for the permeabilization of cells are thoroughly reviewed. We provide an extended review of useful available databases and bioinformatics tools, particularly for setting up genome-scale reconstructed networks. Examples described include phosphorylated carbohydrates, sugar nucleotides, and polyketides.

Abstract
OBJECTIVES To use permeabilized cells of the fission yeast, Schizosaccharomyces pombe, that expresses human UDP-glucose 6-dehydrogenase (UGDH, EC 1.1.1.22), for the production of UDP-glucuronic acid from UDP-glucose. RESULTS In cell extracts no activity was detected. Therefore, cells were permeabilized with 0.3 % (v/v) Triton X-100. After washing away all low molecular weight metabolites, the permeabilized cells were directly used as whole cell biocatalyst. Substrates were 5 mM UDP-glucose and 10 mM NAD(+). Divalent cations were not added to the reaction medium as they promoted UDP-glucose hydrolysis. With this reaction system 5 mM UDP-glucose were converted into 5 mM UDP-glucuronic acid within 3 h. CONCLUSIONS Recombinant permeabilized cells of S. pombe can be used to synthesize UDP-glucuronic acid with 100 % yield and selectivity.

Abstract
We constructed and applied a recombinant, permeabilized Escherichia coli strain for the multistep synthesis of UDP-glucose. Sucrose phosphorylase (E.C. 2.4.1.7) of Leuconostoc mesenteroides was over expressed and the pgm gene encoding for phosphoglucomutase (E.C. 5.4.2.2) was deleted in E. coli to yield the E. coli JW 0675-1 SP strain. The cells were permeabilized with the detergent Triton X-100 at 0.05 % v/v. The synthesis of UDP-glucose with permeabilized cells was then optimized with regard to pH, cell density during the synthesis and growth phase during cell harvest, metal cofactor, other media components, and temperature. In one configuration sucrose, phosphate, UMP, and ATP were used as substrates. At pH 7.8, 27 mg/ml cell dry weight, cell harvest during the early stationary phase of growth and Mn(2+) as cofactor a yield of 37 % with respect to UMP was achieved at 33 °C. In a second step, ATP was regenerated by feeding glucose and using only catalytic amounts of ATP and NAD(+). A UDP-glucose yield of 60 % with respect to UMP was obtained using this setup. With the same setup but without addition of external ATP, the yield was 54%.

CTAB, Triton X-100 and freezing-thawing treatments of Candida guilliermondii: effects on permeability and accessibility of the glucose-6-phosphate dehydrogenase, xylose reductase and xylitol dehydrogenase enzymes. N Biotechnol 2011; 29:192-8. [PMID: 21664992 DOI: 10.1016/j.nbt.2011.05.011] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2010] [Revised: 05/20/2011] [Accepted: 05/24/2011] [Indexed: 11/29/2022]
Abstract
Cells of Candida guilliermondii (ATCC 201935) were permeabilised with surfactant treatment (CTAB or Triton X-100) or a freezing-thawing procedure. Treatments were monitored by in situ activities of the key enzymes involved in xylose metabolism, that is, glucose-6-phosphate dehydrogenase (G6PD), xylose reductase (XR) and xylitol dehydrogenase (XD). The permeabilising ability of the surfactants was dependent on its concentration and incubation time. The optimum operation conditions for the permeabilisation of C. guilliermondii with surfactants were 0.41 mM (CTAB) or 2.78 mM (Triton X-100), 30°C, and pH 7 at 200 rpm for 50 min. The maximum permeabilisation measured in terms of the in situ G6PD activity observed was, in order, as follows: CTAB (122.4±15.7U/g(cells)) > freezing-thawing (54.3 ± 1.9U/g(cells))>Triton X-100 (23.5 ± 0.0U/g(cells)). These results suggest that CTAB surfactant is more effective in the permeabilisation of C. guilliermondii cells in comparison to the freezing-thawing and Triton X-100 treatments. Nevertheless, freezing-thawing was the only treatment that allowed measurable in situ XR activity. Therefore, freezing-thawing permeabilised yeast cells could be used as a source of xylose reductase for analytical purposes or for use in biotransformation process such as xylitol preparation from xylose. The level of in situ xylose reductase was found to be 13.2 ± 0.1 U/g(cells).
