Recent Findings in Nanoparticles Described by Researchers from University of Limerick (Evidence for Distinct Electron Transfer Processes in Terminal Oxidases from Different Origin by Means of Protein Film Voltammetry)

By a News Reporter-Staff News Editor at Life Science Weekly -- Research findings on Nanoparticles are discussed in a new report. According to news reporting out of Limerick, Ireland, by NewsRx editors, research stated, "Cytochrome aa(3) from Paracoccus denitrificans and cytochrome ba(3) from Therms thermophilus, two distinct members of the heme copper oxidase superfamily, were immobilized on electrodes modified with gold nanoparticles."

Our news journalists obtained a quote from the research from the University of Limerick, "This procedure allowed us to achieve direct electron transfer between the enzyme and the gold nanoparticles and to obtain evidence for different electrocatalytic properties of the two enzymes. The pH dependence and thermostability reveal that the enzymes are highly adapted to their native environments."

According to the news editors, the research concluded: "These results suggest that evolution resulted in different solutions to the common problem of electron transfer to oxygen."
