SYSTEMATIC NAME

hydrazine:ferricytochrome-c oxidoreductase
The enzyme, characterized from anaerobic ammonia oxidizers (anammox bacteria), is one of only two enzymes that are known to form an N-N bond (the other being EC 1.7.1.14, nitric oxide reductase [NAD(P)+, nitrous oxide-forming]). The enzyme from the bacterium Candidatus Kuenenia stuttgartiensis is heterotrimeric and contains multiple c-type cytochromes.
