The effects of denitrifying bacteria can also be advantageous. They have recently
been used to reduce nitrogen oxides in emissions” and to reduce nitrates in
waste and sewage.*** Because nitrogen oxides and denitrification have such
global effects, understanding how denitrifying bacteria function is of profound
environmental importance. In denitrifying bacteria, the interconversion of all the
nitrogen oxides are carried out by metalloenzymes (Figure 1-2).” The enzyme

In a physiological sense, denitrification is an anaerobic analogue to dioxygen
respiration (Figure 1.3). The key enzymes in aerobic respiration are cytochrome c
or quinol oxidases acting as terminal oxidases. The NO3", NO2", NO and N2O
reductases can function as terminal oxidases collectively or individually in the
denitrification pathway. Figure 1.3. Comparison between bacterial aerobic
respiration and denitrification. Adapted from reference 1 7. 1.2.2. Metalloenzymes

Aerobic conditions and sufficient buffer capacity for the resulting protons in soil or
mineral material (atmospheric weathering) are indispensable. Some
metalloenzymes for certain stages of ^nitrification, a process which is gaining
importance for ecological reasons [27], have already been introduced: the
molybdenum-containing nitrate(N+v) reductase (-» nitrite), the copper or heme-
iron containing nitrite(N+i") reductases (see Section 6.5 and 10.3), and the
copper-containing dinitrogen ...

The reverse process of the nitrogen fixing is called denitrification process. In this
process, nitrate or nitrite ion is reduced to nitrogen gas via nitric oxide and nitrous
oxide by many metalloenzymes, nitrate reducatse, nitrite reductase, nitric oxide
reductase, and nitrous oxide reductase. In this project, we are studying the
molecular mechanism of these metalloenzymes relating to the denitrification
process. these copper(I) carbonyl complexes do not show any evidence of. probe

Small, discrete model complexes and derived intermediates generally can be
more readily characterized with higher resolution by a variety of spectroscopic
and analytical techniques as compared to metalloproteins. 1.2 Anaerobic
Respiration: Denitrification Many bacteria and fungi can survive in dioxygen free
environments (anaerobic environments) by utilizing nitrogen oxides instead of
dioxygen to produce energy and therefore support cell growth. During this
anaerobic respiration ...
