Functional characterization of a stereospecific diol dehydrogenase, FucO, from Escherichia coli: Substrate specificity, pH dependence, kinetic isotope effects and influence of solvent viscosity

FucO, (S)-1,2-propanediol oxidoreductase, from Escherichia coli is involved in the anaerobic catabolic metabolism of l-fucose and l-rhamnose, catalyzing the interconversion of lactaldehyde to propanediol. The enzyme is specific for the S-enantiomers of the diol and aldehyde suggesting stereospecificity in catalysis. We have studied the enzyme kinetics of FucO with a spectrum of putative alcohol and aldehyde substrates to map the substrate specificity space. Additionally, for a more detailed analysis of the kinetic mechanism, pH dependence of catalysis, stereochemistry in hydride transfer, deuterium kinetic isotope effect of hydride transfer and effect of increasing solvent viscosity were also analyzed. The outcome of this study can be summarized as follows: FucO is highly stereospecific with the highest E-value measured to be 320 for the S-enantiomer of 1,2-propanediol. The enzyme is strictly regiospecific for oxidation of primary alcohols. The enzyme prefers short-chained (2-4 carbons) substrates and does not act on bulkier compounds such as phenyl-substituted alcohols. FucO is an ‘A-side’ dehydrogenase transferring the pro-R-hydrogen of NADH to the aldehyde substrate. The deuterium KIEs of kcat and k cat/KM were 1.9 and 4.2, respectively, illustrating that hydride transfer is partially rate limiting but also that other reaction steps contribute to rate limitation of catalysis. Combining the KIE results with the observed effects of increasing medium viscosity proposed a working model for the kinetic mechanism involving slow, rate limiting, product release and on-pathway conformational changes in the enzyme-nucleotide complexes.

Indolyl Azaspiroketal Mannich Bases Are Potent Antimycobacterial Agents with Selective Membrane Permeabilizing Effects and in Vivo Activity

The inclusion of an azaspiroketal Mannich base in the membrane targeting antitubercular 6-methoxy-1-n-octyl-1H-indole scaffold resulted in analogs with improved selectivity and submicromolar activity against Mycobacterium tuberculosis H37Rv. The potency enhancing properties of the spiro-fused ring motif was affirmed by SAR and validated in a mouse model of tuberculosis. As expected for membrane inserting agents, the indolyl azaspiroketal Mannich bases perturbed phospholipid vesicles, permeabilized bacterial cells, and induced the mycobacterial cell envelope stress reporter promoter piniBAC. Surprisingly, their membrane disruptive effects did not appear to be associated with bacterial membrane depolarization. This profile was not uniquely associated with azaspiroketal Mannich bases but was characteristic of indolyl Mannich bases as a class. Whereas resistant mycobacteria could not be isolated for a less potent indolyl Mannich base, the more potent azaspiroketal analog displayed low spontaneous resistance mutation frequency of 10-8/CFU. This may indicate involvement of an additional envelope-related target in its mechanism of action.

Kinetic Resolution of 1,2-Diols via NHC-Catalyzed Site-Selective Esterification

A kinetic resolution of 1,2-diols bearing both a secondary and a primary alcohol motif through an N-heterocyclic carbene-catalyzed oxidative acylation reaction has been developed. A site- and enantioselective esterification reaction is involved for this process. Both the monoacylated diols obtained and the remaining enantioenriched 1,2-diols are versatile building blocks for the preparation of functional molecules with proven biological activities.

Preparation of Optically Active 1,2-Diols and alpha-Hydroxy Ketones Using Glycerol Dehydrogenase as Catalyst: Limits to Enzyme-Catalyzed Synthesis due to Noncompetitive and Mixed Inhibition by Product

Glycerol dehydrogenase (GDH, EC 1.1.1.6, from Enterobacter aerogenes or Cellulomonas sp.) catalyzes the interconversion of analogues of glycerol and dihydroxyacetone.Its substrate specificity is quite different from than of horse liver alcohol dehydrogenase (HLADH), yeast alcohol dehydrogenase, and other alcohol dehydrogenases used in enzyme-catalyzed organic synthesis and is thus a useful new enzymic catalyst for the synthesis of enantiomerically enriched and isotopically labeled organic molecules.This paper illustrates synthetic applications of GDH as a reduction catalyst by the enantioselective reduction of 1-hydroxy-2-propanone and 1-hydroxy-2-butanone to the corresponding R 1,2-diols (ee = 95-98percent). (R)-1,2-Butanediol-2-d1 was prepared by using formate-d1 as the ultimate reducing agent.Comparison of (R)-1,2-butanediol prepared by reduction of 1-hydroxy-2-butanone enzymatically and with actively fermenting bakers’ yeast indicated than yield and enantiomeric purity were similar by the two procedures.Reactions proceeding in the direction of substrate oxidation usually suffer from slow rates and incomplete conversions due to product inhibition.The kinetic consequences of product inhibition (competitive, noncompetitive, and mixed) for practical synthetic applications of GDH, HLADH, and other oxidoreductases are analyzed.In general, product inhibition seems the most serious limitation to the use of these enzymes as oxidation catalysts in organic synthesis.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Recommanded Product: 4254-15-3. I hope my blog about 4254-15-3 is helpful to your research.
