Proteins: Structure, Function, and Bioinformatics, EarlyView.ABSTRACT Anaerobic ammonium‐oxidizing (anammox) bacteria employ a unique, hydrazine‐based pathway to obtain energy from nitrite and ammonium. These organisms possess distinct Rieske/cytochrome b complexes whose precise role in anammox metabolism remains unclear, but which have been proposed to include the generation of NAD(P)H.

Analysis of acid-stressed Bacillus cereus reveals a major oxidative response and inactivation-associated radical formation [PDF]
, 2010 Acid stress resistance of the food-borne human pathogen Bacillus cereus may contribute to its survival in acidic environments, such as encountered in soil, food and the human gastrointestinal tract. The acid stress responses of B.

The FEBS Journal, EarlyView.Nitrate from food is first converted to nitrite by oral bacteria and then further processed in the intestine. The gut microbiota reduces nitrate and nitrite to ammonia or nitric oxide, preventing the formation of carcinogenic nitrosamines. Our analysis highlights Escherichia coli as a key player in this detoxification process, supported by other ...

E. coli and gut health—For the loser now will be later to win
The FEBS Journal, EarlyView.In humans, commensal gut bacteria participate in a miniature nitrogen cycle, metabolizing dietary nitrate and nitrite. While these processes can generate harmful N‐nitrosamines, they may also produce beneficial nitric oxide (NO) or ammonium. Hager and colleagues demonstrate that E.

Modeling the effect of copper availability on bacterial denitrification [PDF]
, 2013 When denitrifying bacteria such as Paracoccus denitrificans respire anaerobically they convert nitrate to dinitrogen gas via a pathway which includes the potent greenhouse gas, nitrous oxide (NO). The copper-dependent enzyme Nitrous Oxide reductase (Nos)
