Nitrate and periplasmic nitrate reductases [PDF]

open access: yesChem. Soc. Rev., 2014
The nitrate anion is a simple, abundant and relatively stable species, yet plays a significant role in global cycling of nitrogen, global climate change, and human health. Although it has been known for quite some time that nitrate is an important species environmentally, recent studies have identified potential medical applications.
