Alcaligenes 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 ...
متن کامل+)-Lactate Dehydrogenase from the Strict Aerobe Alcaligenes eutrophus
The L( +)-lactate dehydrogenase (EC 1.1.1.27) of Alcaligenes eutrophus catalyzes the NADH-dependent reduction of pyruvate and a few other 2-oxoacids. The K,,, values for NADH, NAD, pyruvate and L( +)-lactate are 0.075 mM, 0.130 mM, 0.820 mM and 7.10 mM, respectively. The reaction follows a rapid equilibrium ordered bi-bi mechanism and involves the formation of a dead-end EBQ complex. The compet...
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 کاملRefinement of the structure of pseudoazurin from Alcaligenes faecalis S-6 at 1.55 A resolution.
The crystal structure of the redox protein pseudoazurin (123 amino acid residues; molecular weight 13,000 daltons) from Alcaligenes faecalis has been refined by fast Fourier restrained least-squares minimization. Cycles of rebuilding were carried out to escape from local minima. Individual isotropic temperature factor values were refined separately for all atoms. The R factor was reduced from 0...
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...
