Chlorite dismutase, also known as Chlorite O2-lyase (EC 1.13.11.49), is an enzyme that catalyzes the chemical reaction

ClO
2
→ Cl
+ O
2

Reactions that generate oxygen molecules are exceedingly rare in biology and difficult to mimic synthetically. Perchlorate-respiring bacteria enzymatically detoxify chlorite (ClO
2
), the end product of the perchlorate (ClO
4
) respiratory pathway, by converting it to dioxygen (O
2
) and chloride (Cl
).[1] Chlorite dismutase is a hemoprotein, but it bears no structural or sequence relationships with known peroxidases or other heme proteins, and is part of a large family of proteins with more than one biochemical function.
