In the ancient anaerobic environment, ferrous iron (Fe2+) was one of the first metal
cofactors. Oxygenation of the ancient world challenged bacteria to acquire the insoluble …

Nitrate is generally considered a water pollutant and an undesirable fertilizer residue in the
food chain. Research in the 1970s indicated that, by reducing nitrate to nitrite, commensal …

Nitrous oxide (N2O) is an environmentally important atmospheric trace gas because it is an
effective greenhouse gas and it leads to ozone depletion through photo-chemical nitric …

Ammonia oxidizing bacteria extract energy for growth from the oxidation of ammonia to
nitrite. Ammonia monooxygenase, which initiates ammonia oxidation, remains enigmatic …

The investigation of respiratory N-oxide reduction as part of a biogeochemical process
sustained by prokaryotes has roots over a century ago and has laid the groundwork for …

Microbial flavohemoglobins (flavoHbs) and hemoglobins (Hbs) show large NO
dioxygenation rate constants ranging from 745 to 2900 μM− 1s− 1 suggesting a primal NO …

Abstract Background Initial interest in Dechloromonas aromatica strain RCB arose from its
ability to anaerobically degrade benzene. It is also able to reduce perchlorate and oxidize …

Fur is a well‐known iron‐responsive repressor of gene transcription, which is used by many
bacteria to respond to the low‐iron environment that pathogens encounter during infection …

Iron is limiting in the human host, and bacterial pathogens respond to this environment by
activating genes required for bacterial virulence. Transcriptional regulation in response to …

During infection Neisseria meningitidis (Nm) encounters multiple environments within the
host, which makes rapid adaptation a crucial factor for meningococcal survival. Despite the …
