Bioelectrocatalytic performance of D-Fructose dehydrogenase
Bioelectrochemistry 2019 Oct;129:1-9.PMID:31063949DOI:10.1016/j.bioelechem.2019.04.024.
This review summarizes the bioelectrocatalytic properties of D-Fructose dehydrogenase (FDH), while taking into consideration its enzymatic characteristics. FDH is a membrane-bound flavohemo-protein with a molecular mass of 138 kDa, and it catalyzes the oxidation of D-Fructose to 5-keto-d-fructose. The characteristic feature of FDH is its strong direct-electron-transfer (DET)-type bioelectrocatalytic activity. The pathway of the DET-type reaction is discussed. An overview of the application of FDH-based bioelectrocatalysis to biosensors and biofuel cells is also presented, and the benefits and problems associated with it are extensively discussed.
1,5-anhydro-D-fructose from D-Fructose
Carbohydr Res 2007 Jul 2;342(9):1249-53.PMID:17368437DOI:10.1016/j.carres.2007.02.026.
1,5-anhydro-D-fructose was efficiently prepared from D-Fructose via regiospecific 1,5-anhydro ring formation of 2,3-O-isopropylidene-1-O-methyl(tolyl)sulfonyl-D-fructopyranose and subsequent deprotection.
Synthesis of 1-Deoxymannojirimycin from D-Fructose using the Mitsunobu Reaction
J Org Chem 2022 Dec 16;87(24):16895-16901.PMID:36460300DOI:10.1021/acs.joc.2c02174.
Three different Mitsunobu reactions have been investigated for the synthesis of 1-deoxymannojirimycin (1-DMJ) from D-Fructose. The highest yielding and most practical synthesis can be undertaken on a 10 g scale with minimal chromatography. In the key step, N,O-di-Boc-hydroxylamine reacts with methyl 1,3-isopropylidene-α-d-fructofuranose under Mitsunobu conditions to give 14. Acidic hydrolysis affords nitrone 15, which reduces quantitatively via catalytic hydrogenolysis to afford 1-DMJ (4) in 55% overall yield from D-Fructose (cf. 37% for azide route and 29% for nosyl route).
Metabolically Engineered Escherichia coli for Conversion of D-Fructose to D-Allulose via Phosphorylation-Dephosphorylation
Front Bioeng Biotechnol 2022 Jun 22;10:947469.PMID:35814008DOI:10.3389/fbioe.2022.947469.
D-Allulose is an ultra-low calorie sweetener with broad market prospects. As an alternative to Izumoring, phosphorylation-dephosphorylation is a promising method for D-allulose synthesis due to its high conversion of substrate, which has been preliminarily attempted in enzymatic systems. However, in vitro phosphorylation-dephosphorylation requires polyphosphate as a phosphate donor and cannot completely deplete the substrate, which may limit its application in industry. Here, we designed and constructed a metabolic pathway in Escherichia coli for producing D-allulose from D-Fructose via in vivo phosphorylation-dephosphorylation. PtsG-F and Mak were used to replace the fructose phosphotransferase systems (PTS) for uptake and phosphorylation of D-Fructose to fructose-6-phosphate, which was then converted to D-allulose by AlsE and A6PP. The D-allulose titer reached 0.35 g/L and the yield was 0.16 g/g. Further block of the carbon flux into the Embden-Meyerhof-Parnas (EMP) pathway and introduction of an ATP regeneration system obviously improved fermentation performance, increasing the titer and yield of D-allulose to 1.23 g/L and 0.68 g/g, respectively. The E. coli cell factory cultured in M9 medium with glycerol as a carbon source achieved a D-allulose titer of ≈1.59 g/L and a yield of ≈0.72 g/g on D-Fructose.
Synthesis of natural/13C-enriched d-tagatose from natural/13C-enriched D-Fructose
Carbohydr Res 2021 Sep;507:108377.PMID:34303197DOI:10.1016/j.carres.2021.108377.
A concise, easily scalable synthesis of a rare ketohexose, d-tagatose, was developed, that is compatible with the preparation of d-[UL-13C6]tagatose. Epimerization of the widely available and inexpensive ketohexose D-Fructose at the C-4 position via an oxidation/reduction (Dess-Martin periodinane/NaBH4) was a key step in the synthesis. Overall, fully protected natural d-tagatose (3.21 g) was prepared from D-Fructose (9 g) on a 50 mmol scale in 23% overall yield, after five steps and two chromatographic purifications. d-[UL-13C6]Tagatose (92 mg) was prepared from d-[UL-13C6]fructose (465 mg, 2.5 mmol) in 16% overall yield after six steps and four chromatographic purifications.
