Identification and molecular characterization of the Alcaligenes eutrophus H16 aco operon genes involved in acetoin catabolism.
Acetoin:dichlorophenolindophenol oxidoreductase (Ao:DCPIP OR) and the fast-migrating protein (FMP) were purified to homogeneity from crude extracts of acetoin-grown cells of Alcaligenes eutrophus. Ao:DCPIP OR consisted of alpha and beta subunits (Mrs, 35,500 and 36,000, respectively), and a tetrameric alpha 2 beta 2 structure was most likely for the native protein. The molecular weight of FMP s...
متن کاملDissimilation of aromatic compounds by Alcaligenes eutrophus.
The range of aromatic compounds that support the growth of Alcaligenes eutrophus has been determined, and the pathways used for the dissimilation of these substrates have been explored, largely by enzymatic analyses. The beta-ketoadipate pathway operates in the dissimilation of benzoate and p-hydroxybenzoate; the genetisate pathway, in the dissimilation of m-hydroxybenzoate; and the meta cleava...
متن کاملDenitrification by Alcaligenes eutrophus is plasmid dependent.
Curing of the hydrogenase-specifying megaplasmid pHG indigenous to strains of the facultative lithoautotrophic bacterium Alcaligenes eutrophus was correlated with a loss of denitrifying ability (Nitd). The retransfer of plasmid pHG1 reconstituted the Nitd phenotype. Plasmid-free mutants were still capable of converting some nitrate to nitrite, but they did not metabolize nitrite under anaerobic...
متن کاملBiochemical and molecular characterization of the Alcaligenes eutrophus pyruvate dehydrogenase complex and identification of a new type of dihydrolipoamide dehydrogenase.
Sequence analysis of a 6.3-kbp genomic EcoRI-fragment of Alcaligenes eutrophus, which was recently identified by using a dihydrolipoamide dehydrogenase-specific DNA probe (A. Pries, S. Hein, and A. Steinbüchel, FEMS Microbiol. Lett. 97:227-234, 1992), and of an adjacent 1.0-kbp EcoRI fragment revealed the structural genes of the A. eutrophus pyruvate dehydrogenase complex, pdhA (2,685 bp), pdhB...
متن کاملAlcaligenes eutrophus as a bacterial chromate sensor.
In Alcaligenes eutrophus CH34, determinants encoding inducible resistance to chromate (chr) and to cobalt and nickel (cnr) are located adjacent to each other on plasmid pMOL28. To develop metal-sensing bacterial strains, a cloned part of plasmid pMOL28, which contains both determinants, was mutated with Tn5-lacZ. The chr::lacZ fusions were specifically induced by chromium; cnr was induced best ...
