Mercury Reduction and Methyl Mercury Degradation by the Soil Bacterium Xanthobacter autotrophicus Py2.
Two previously uncharacterized potential broad-spectrum mercury (Hg) resistance operons (mer) are present on the chromosome of the soil Alphaproteobacteria Xanthobacter autotrophicus Py2. These operons, mer1 and mer2, contain two features which are commonly found in mer operons in the genomes of soil and marine Alphaproteobacteria, but are not present in previously characterized mer operons: a ...
متن کاملDegradation of halogenated aliphatic compounds by Xanthobacter autotrophicus GJ10.
A bacterium that is able to utilize a number of halogenated short-chain hydrocarbons and halogenated carboxylic acids as sole carbon source for growth was identified as a strain of Xanthobacter autotrophicus. The organism constitutively produces two different dehalogenases. One enzyme is specific for halogenated alkanes, whereas the other, which is more heat stable and has a higher pH optimum, ...
متن کاملIsolation of a hydrogenase-cytochrome b complex from cytoplasmic membranes of Xanthobacter autotrophicus GZ 29
The aerobic nitrogen-fixing hydrogen bacterium Xanthobacter autotrophicus strain GZ29 [1] can grow autotrophically with hydrogen, oxygen, carbon dioxide, and molecular nitrogen as sole sources of electrons, energy, carbon, and nitrogen. Carbon dioxide is fixed via the Calvin cycle, and for activation of hydrogen only a membrane-bound hydrogenase activity was detected which does not reduce NAD [...
متن کاملExploring the binding sites of the haloalkane dehalogenase DhlA from Xanthobacter autotrophicus GJ10.
The catalytic site of haloalkane dehalogenase DhlA is buried more than 10 A from the protein surface. While potential access channels to this site have been reported, the precise mechanism of substrate import and product export is still unconfirmed. We used computational methods to examine surface pockets and their putative roles in ligand access to and from the catalytic site. Computational so...
متن کاملComparative study of the ability of three xanthobacter species to metabolize cycloalkanes.
The ability of three species of Xanthobacter to metabolize cyclohexane and its derivatives has been compared. Xanthobacter flavus was unable to utilize any of the cycloalkanes under investigation. X. autotrophicus was unable to utilize cyclohexane but was able to grow with a limited range of substituted cycloalkanes, including cyclohexanol and cyclohexanone. Comparison of a previously isolated ...
