Abstract:

Nitrous oxide (N2O) is an important greenhouse gas that is also responsible for stratospheric ozone depletion [1, 2]. Human activity is the main source of N2O due to the use of fertilisers in agriculture. Nitrous oxide reductase (N2OR) is the only enzyme to destroy N2O as part of a biological process termed denitrification. This enzyme has a unique catalytic CuZ centre, an electron transfer CuA centre and a high demand for Cu with 12 atoms required per functional dimer. A previous transcriptomic study revealed that two putative Cu chaperones, ScoB and PCuC were upregulated under Cu limiting co

The family comprises approximately 2000 species in 300 genera (Ben-Dov 1994), of which 20 species are pests of cultivated plants in South Africa (Annecke & Moran 1982). In South Africa, approximately 109 species of mealybugs have been recorded from 50 genera (Millar 2002). Chapter 2 - The effect of constant temperatures on the development, survival and fecundi

Full text

Abstract:

The effect of nitrite stress induced in Paracoccus denitrificans PD1222 was examined using additions of sodium nitrite to an aerobic bacterial culture. Nitrite generates a strong stress response in P. denitrificans, causing growth inhibition. This is dependent on both the concentration of nitrite present and the pH. The pH dependent effect of nitrite growth inhibition is likely a result of nitrite and free nitrous acid (FNA; pKa = 3.16) and subsequent reactive nitrogen oxides, generated from the intracellular passage of FNA into P. denitrificans.

Abstract:

A study of the electron transfers associated with the cytochrome c peroxidase of Paracoccus denitrificans has been made. The peroxidase is similar to the well-studied enzyme from Pseudomonas aeruginosa, although significant differences do exist. Like the Pseudomonas enzyme, the Paracoccus peroxidase contains two haem c groups, one high potential (Em=+226mV) and one low potential (Em≈-100mV). The high potential haem acts as a source of the second electron for hydrogen peroxide reduction and the low potential haem acts as a peroxidatic centre. Th

Abstract:

Denitrification is an anaerobic process performed by several soil bacteria as an alternative to aerobic respiration. A key-step in denitrification (the N-N-bond is made) is catalyzed by nitric oxide reductase (NOR); 2NO + 2e- + 2H+ → N2O + H2O. NOR from Paracoccus denitrificans is a member of the heme copper oxidase superfamily (HCuOs), where the mitochondrial cytochrome c oxidase is the classical example. NOR is situated in the cytoplasmic membrane and can, as a side reaction, catalyze the reduction of oxygen to water. NORs have properties that make them divergent members of the HCuOs; the re

Abstract:

Paracoccus denitrificans, a model Alphaproteobacteria soil denitrifier, can grow solely on nitrate or nitrite as inorganic nitrogen sources using a specialised cytoplasmic assimilatory nitrate/nitrite reducing pathway; Nas. This growth capability is phylogenetically represented throughout heterotrophic and autotrophic bacteria, plants and fungi. Whilst this metabolism has been extensively studied in the latter two, the regulatory mechanisms by which organoheterotrophic bacteria govern this nitrate-dependant metabolism are less understood.
