A procedure for solubilization of the oxygen-labile, membrane-bound diol dehydratase from Clostridium glycolicum with retention of enzymatic activity is described. The procedure involves sonication of crude membrane preparations anaerobically in 0.1 M 2-(N-cyclohexylamino)ethane-sulfonic acid (CHES) buffer (pH 8.6-9.0) containing 2 mM dithiothreitol. The addition of dimethylsulfoxide (30%) and ...

Generally, rotational isomerization about the carbon-carbon single bond in simple ethane derivatives in room-temperature solution under thermal equilibrium conditions has been too fast to measure. We achieved this goal using two-dimensional infrared vibrational echo spectroscopy to observe isomerization between the gauche and trans conformations of an ethane derivative, 1-fluoro-2-isocyanato-et...

We recently proposed Ethane: A clean-slate approach to managing and securing enterprise networks. The goal of Ethane is to make enterprise networks (e.g. networks in companies, universities, and home offices) much easier to manage. Ethane is built on the premise that the only way to manage and secure networks is to make sure we can identify the origin of all traffic, and hold someone (or some m...

The title compound, C(6)H(10)N(8)S(2), was prepared by the nucleophilic substitution reaction of 5-mercapto-1-methyl-tetra-zole and dichloro-ethane. In the crystal, the mol-ecule possesses an approximate non-crystallographic twofold symmetry axis. The crystal packing is stabilized by weak inter-molecular C-H⋯N and π-π inter-actions [centroid-centroid distances = 3.448 (6), 3.5085 (5) and 3.4591...

Ethane exhalation was measured in 42 control subjects, 52 patients with various non-alcoholic liver diseases, and 89 alcohol abusers who had been admitted to hospital for alcohol withdrawal and assessment of liver disease (six with normal liver tests, 10 with steatosis with or without fibrosis, six with alcoholic hepatitis, 29 with cirrhosis, 34 with both cirrhosis and alcoholic hepatitis, and ...

Mixed ligand com plexes of bis(phenyldithiocarbazato)nickel(II) with triphenylphosphane and a number of ditertiary phosphanes have been synthesised. The com plexes were characterised on the basis of molar conductance, magnetic moment values, electronic and IR spectra. Out of the five prepared com plexes the mixed ligand com plexes with triphenylphosphane and bis(diphenylphosphino)m ethane are p...

The retrieval of data from the Cassini-Huygens mission has revealed much about Titan's atmospheric-surface system and has precipitated more questions. One of these questions involves the lack of large reservoirs of ethane that were predicted by a variety of studies prior to the arrival of the Cassini-Huygens spacecraft. Using an updated and comprehensive photochemical model, we examine the natu...

Light dependent ethane formation and chlorophyll bleaching in isolated chloroplast lamellae are enhanced by either methylviologen or a-linolenic acid. Both ethane formation and chloro­ phyll bleaching are also enhanced in chloroplast particles deficient in photosynthetic electron transport, e. g. after aging, heat treatm ent or digitonin fragmentation. Ethane formation by sub­ chloroplast parti...
