Determination of the Paracoccus denitrificans SOS box.

Redefining Paracoccus denitrificans and Paracoccus pantotrophus and the case for a reassessment of the strains held by international culture collections.

An outline of the current taxonomic diversity of the genus Paracoccus is presented. A definitive summary is given of the valid type strains of Paracoccus denitrificans and Paracoccus pantotrophus and of culture collection strains that can be assigned to these species. The case is established for a critical reassessment of the P. denitrificans strains held by international culture collections, t...

An improved medium for the anaerobic growth of Paracoccus denitrificans Pd1222

Paracoccus denitrificans is a well studied model organism with respect to its aerobic and anaerobic respiratory enzymes. However, until now, the growth medium for this organism has not been optimized for anaerobic growth. In particular, the requirements of P. denitrificans for trace elements (TEs) are not well known. In the present study we aimed to improve growth rates of P. denitrificans Pd12...

H(+)-translocating NADH-quinone oxidoreductase (NDH-1) of Paracoccus denitrificans. Studies on topology and stoichiometry of the peripheral subunits.

The proton-translocating NADH-quinone oxidoreductase (NDH-1) of Paracoccus denitrificans is composed of at least 14 subunits (NQO1-14) and is located in the cytoplasmic membrane. In the present study, topological properties and stoichiometry of the 7 subunits (NQO1-6 and NQO9) of the P. denitrificans NDH-1 in the membranes were investigated using immunological techniques. Treatments with chaotr...

Structure of a catalytic dimer of the α- and β-subunits of the F-ATPase from Paracoccus denitrificans at 2.3 Å resolution

The structures of F-ATPases have predominantly been determined from mitochondrial enzymes, and those of the enzymes in eubacteria have been less studied. Paracoccus denitrificans is a member of the α-proteobacteria and is related to the extinct protomitochondrion that became engulfed by the ancestor of eukaryotic cells. The P. denitrificans F-ATPase is an example of a eubacterial F-ATPase that ...
