IntEnz Enzyme Nomenclature


Accepted name:
chlorite O2-lyase
Other name:
chlorite dismutase [misleading]
Systematic name:
chloride:oxygen oxidoreductase




Reaction occurs in the reverse direction in chlorate- and perchlorate-reducing bacteria. There is no activity when chlorite is replaced by hydrogen peroxide, perchlorate, chlorate or nitrite. The term 'chlorite dismutase' is misleading as the reaction does not involve dismutation/disproportionation. Contains iron and protoheme IX.
