Title
The electron transport chains of Neisseria meningitidis: Organization and regulation of meningococcal respiratory chains,Used
Delivery time: 8-12 business days (International)
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 ctype and btype cytochromes while nitrite or nitric oxide cause oxidation of btype cytochrome predominantly. Nitrite as well as nitric oxide can directly inhibits oxidation of ctype cytochromes by oxygen. The meningococcus posseses many periplasmic electron transferring proteins. These proteins include cytochrome c2, cytochrome c4, cytochrome c5, and lipidmodified azurin. The cytochromes c2 and c4 are major electron donors to cytochrome cbb3 oxidase whereas the cytochrome c5 is a major electron donor to coppercontaining nitrite reductase. The cytochrome c5 and lipidmodified 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.
