This chapter covers the current understanding of the biochemical and genetic underpinnings
relevant to ammonia oxidation by aerobic bacteria. Ammonia is released into the …

The tetraheme cytochrome c 554 (cyt c 554) from Nitrosomonas europaea is believed to
function as an electron-transfer protein from hydroxylamine oxidoreductase (HAO). We show …

Nitrous oxide (N 2 O) emissions contribute to nitrogen loss and exacerbate the greenhouse
effect during composting. Investigating the efficacy and underlying mechanisms of …

This chapter talks about ammonium‐oxidizing bacteria (AOB), addresses the inventory
involved in nitrification, attempts metabolic reconstruction of N transformation processes …

Hydroxylamine oxidoreductase (HAO) from the ammonia-oxidizing bacterium Nitrosomonas
europaea normally catalyzes the four-electron oxidation of hydroxylamine to nitrite, which is …

Cytochromes-P460 of Nitrosomonas europaea and Methylococcus capsulatus (Bath), and
the cytochrome c′ of M. capsulatus, believed to be involved in binding or transformation of …

Multiheme cytochromes (MHCs) are bacterial electron-transfer proteins. We show from
optical spectra and calculations that some of these cytochromes probably contain occupied …

Heme cofactors are found in a wide range of proteins, where they play various roles in eg,
steroid and bioactive lipid synthesis, energy transduction, gene regulation,'cellular signaling …

Multiheme cytochromes c constitute a widespread class of proteins with essential functions
in electron transfer and enzymatic catalysis. Their functional properties are in part …

The diheme cytochrome NapB constitutes the small subunit of a periplasmic nitrate
reductase found in a wide variety of bacterial species, including pathogens. The NapB …
