Application


  • Changes in physicochemical properties and microbial community succession during leaf stacking fermentation.: This research investigates the changes in physicochemical properties and microbial communities during leaf fermentation, with a focus on the role of volatile compounds like 2,3-pentanedione. The study provides insights into fermentation processes and microbial interactions (Zhang et al., 2023).

The reaction of pigeon liver malic enzyme (L-malate:NADP+ oxidoreductase (oxaloacetate-decarboxylating), EC 1.1.1.40) with dicarbonyl compounds (2,3-butanedione, methylglyoxal, 2,4-pentanedione, and phenylglyoxal) resulted in a rapid loss of its enzymatic activity. The inactivation showed pseudo-first-order kinetics for all the dicarbonyls studied. All
Synthesis and biological validation of a ubiquitous quorum-sensing molecule.

Incubation of homogeneous preparations of L-threonine dehydrogenase from Escherichia coli with 2,3-butanedione, 2,3-pentanedione, phenylglyoxal, or 1,2-cyclohexanedione causes a time- and concentration-dependent loss of enzymatic activity; plots of log percent activity remaining versus time are linear to greater than 90% inactivation
Paul Schweiger et al.
Applied microbiology and biotechnology, 87(4), 1415-1426 (2010-04-24)
Two cytosolic NADPH-dependent carbonyl reductases from Gluconobacter oxydans 621H, Gox0644 and Gox1615, were heterologously produced in Escherichia coli. The recombinant proteins were purified to homogeneity and characterized. Gox0644 and Gox1615 were dimers with native molecular masses of 66.1 and 74.5
