The electron transport chains of Neisseria meningitidis

Organization and regulation of meningococcal respiratory chains

• Broschiertes Buch

Produktbeschreibung

Neisseria meningitidis is a facultative microaerophilic bacterium that can utilize oxygen, nitrite, and nitric oxide as terminal electron acceptors for its respiration. Oxygen can cause oxidation of both c-type and b-type cytochromes while nitrite or nitric oxide cause oxidation of b-type cytochrome predominantly. Nitrite as well as nitric oxide can directly inhibits oxidation of c-type cytochromes by oxygen. The meningococcus posseses many periplasmic electron transferring proteins. These proteins include cytochrome c2, cytochrome c4, cytochrome c5, and lipid-modified azurin. The cytochromes c2 and c4 are major electron donors to cytochrome cbb3 oxidase whereas the cytochrome c5 is a major electron donor to copper-containing nitrite reductase. The cytochrome c5 and lipid-modified azurin, to lesser extent, are also able to donate electrons to cytochrome cbb3 oxidase. Its respiratory flexibility may give the organism an advantage to adapt in environments where fluctuation of respiratory substrates occurs.

Autorenporträt

I am interested in bacterial respiration and had an opportunity to work with James Moir during 2004-2008 at the University of York, UK. After receiving a Ph.D. in Biology, I returned to Thailand and work as a lecturer at Chiang Mai University and continue working on aspects of bacterial respiratory metabolism.
