Reaction: superoxide + reduced rubredoxin + 2 H+ = H2O2 + oxidized rubredoxin
Glossary entries:
rubredoxin = iron-containing protein found in sulfur-metabolizing bacteria and archaea, participating in electron transfer
Other names: neelaredoxin; desulfoferrodoxin
Systematic name: rubredoxin:superoxide oxidoreductase
Comments: The enzyme contains non-heme iron.
