The periplasmic modifier protein for methanol dehydrogenase in the methylotrophs Methylophilus methylotrophus and Paracoccus denitrificans.
A modifier protein (M-protein), which increases the affinity of methanol dehydrogenase (MDH) for alcohols but decreases its affinity for formaldehyde, has been partially purified from Methylophilus methylotrophus and Paracoccus denitrificans. Analysis was complicated by non-protein factors in bacterial extracts that are able to mimic M-protein in one of its functions-that of increasing the acti...
متن کاملZinc-Dependent Transcriptional Regulation in Paracoccus denitrificans
Zinc homeostasis is critical for bacterial survival and is mediated largely at the transcriptional level by the regulation of zinc uptake and efflux genes. Here we use RNA-seq to assess transcriptional changes as a result of zinc limitation in the denitrifying bacterium Paracoccus denitrificans. The results identify the differential expression of 147 genes, most of which were upregulated in zin...
متن کاملPurification and properties of methylamine dehydrogenase from Paracoccus denitrificans.
Methylamine dehydrogenase from Paracoccus denitrificans was purified to homogeneity in two steps from the periplasmic fraction of methylamine-grown cells. The enzyme exhibited a pI value of 4.3 and was composed of two 46,700-dalton subunits and two 15,500-dalton subunits. Each small subunit possessed a covalently bound pyrrolo-quinoline quinone prosthetic group. The amino acid compositions of t...
متن کاملA novel inhibitor of NADH dehydrogenase in Paracoccus denitrificans.
In [ l ] low concentrations of Tinopal AN, (1,l-bis(3,N-5-dimethylbenzoxazol-2-y1)methine p-toluene sulphonate), which is present in the optical brightener Uvitex AN (Ciba-Geigy Ltd) [2], inhibited the aerobic respiration of Paracoccus denitrificans. Using inverted membrane vesicles of P. denitrifcans [I], this inhibition was shown to occur in the NADH dehydrogenase (EC 1.66.99.3) region of the...
متن کاملTwo-component system that regulates methanol and formaldehyde oxidation in Paracoccus denitrificans.
A chromosomal region encoding a two-component regulatory system, FlhRS, has been isolated from Paracoccus denitrificans. FlhRS-deficient mutants were unable to grow on methanol, methylamine, or choline as the carbon and energy source. Expression of the gene encoding glutathione-dependent formaldehyde dehydrogenase (fhlA) was undetectable in the mutant, and expression of the S-formylglutathione ...
