Enzymatic extrusion, instead of traditional steam cooking, to treat rice is an efficient and alternative pretreatment for Chinese rice wine fermentation. In order to determine the formation of volatiles in enzymatic extrusion-processed rice wine (EE), and to ...

Carbonic anhydrases (CAs, EC 4.2.1.1) are inhibited by sulfonamides, inorganic anions, phenols, coumarins (acting as prodrugs) and polyamines. A novel class of CA inhibitors (CAIs), interacting with the CA isozymes I, II (cytosolic) and IX, XII (transmembrane...

Rotationally resolved S(1) <-- S(0) electronic spectra of 1,2-dimethoxybenzene (DMB) and its water complex have been observed and assigned. The derived values of the rotational constants show that the bare molecule has a planar heavy-atom structure with trans...

The Naturally occurring novel cyclohexanonyl bromophenol 2(R)-2-(2,3,6-tribromo-4,5-dihydroxybenzyl)cyclohexanone (4) was synthesized as a racemic compound. Cyclohexylphenyl methane derivatives (10-17) with Br, OMe, CO, and OH were also obtained. Inhibition o...

Definitive X-ray crystallographic evidence is obtained for a single hole (or a polaron) to be uniformly distributed on the three equivalent 1,2-dimethoxybenzenoid (or veratrole) rings in the hexamethoxytriptycene cation radical. This conclusion is further sup...

We applied two-color resonant two-photon mass-analyzed threshold ionization (MATI) spectroscopy to investigate the molecular properties of the selected rotamers of o-dimethoxybenzene (ODMB) and m-dimethoxybenzene (MDMB). The present experimental results show ...

The anaerobic cleavage of ether bonds of methoxylated substrates such as vanillate or veratrol in acetogenic bacteria is mediated by multi-component enzyme systems, the O-demethylases. Acetobacterium dehalogenans harbours different inducible O-demethylases wi...

Arch. Microbiol. 175(5) , 376-83, (2001)

From 3-methoxyphenol-grown cells of Acetobacterium dehalogenans, an inducible enzyme was purified that mediated the transfer of the methyl groups of veratrol (1,2-dimethoxybenzene) to a corrinoid protein enriched from the same cells. In this reaction, veratro...

Arch. Microbiol. 183(6) , 378-84, (2005)

The anaerobic veratrol O-demethylase mediates the transfer of the methyl group of the phenyl methyl ether veratrol to tetrahydrofolate. The primary methyl group acceptor is the cobalt of a corrinoid protein, which has to be in the +1 oxidation state to bind t...
