| Abstract |
Nitric oxide reductase (NOR) is a key enzyme in denitrification, reforming the N-N bond (making N2O from two NO molecules) in the nitrogen cycle. It is a cytochrome bc complex which has apparently only two subunits, NorB and NorC. It contains two low-spin cytochromes (c and b), and a high-spin cytochrome b which forms a binuclear center with a non-heme iron. NorC contains the c-type heme and NorB can be predicted to bind the other metal centers. NorB is homologous to the major subunit of the heme/copper cytochrome oxidases, and NOR thus belongs to the superfamily, although it has an Fe/Fe active site rather than an Fe/Cu binuclear center and a different catalytic activity. Current evidence suggests that NOR is not a proton pump, and that the protons consumed in NO reduction are not taken from the cytoplasmic side of the membrane. Therefore, the comparison between structural and functional properties of NOR and cytochrome c- and quinol-oxidizing enzymes which function as proton pumps may help us to understand the mechanism of the latter. This review is a brief summary of the current knowledge on molecular biology, structure, and bioenergetics of NOR as a member of the oxidase superfamily. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 22 January 2013.
All research outputs
#8,535,684
of 25,374,917 outputs
Outputs from Journal of Bioenergetics and Biomembranes
#115
of 491 outputs
Outputs of similar age
#19,961
of 95,112 outputs
Outputs of similar age from Journal of Bioenergetics and Biomembranes
#1
of 1 outputs
Altmetric has tracked 25,374,917 research outputs across all sources so far. This one is in the 43rd percentile – i.e., 43% of other outputs scored the same or lower than it.
So far Altmetric has tracked 491 research outputs from this source. They receive a mean Attention Score of 3.4. This one is in the 39th percentile – i.e., 39% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 95,112 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 17th percentile – i.e., 17% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 1 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
