1.7.2.8

Accepted name:

hydrazine dehydrogenase

Reaction:

hydrazine + 4 ferricytochrome c = N₂ + 4 ferrocytochrome c

Other name(s):

HDH

Systematic name:

hydrazine:ferricytochrome c oxidoreductase

Comments:

The enzyme, which is involved in the pathway of anaerobic ammonium oxidation in anammox bacteria, has been purified from the bacterium Candidatus Kuenenia stuttgartiensis. The electrons derived from hydrazine are eventually transferred to the quinone pool.
