Abstract
Some commercial samples of bovine catalase contain superoxide dismutase activity. Therefore the inhibition of a reaction on the addition of a catalase preparation need not necessarily mean that H2O2 is responsible for the reaction.

Involvement of the Superoxide Anion Radical in the Autoxidation of Pyrogallol and a Convenient Assay for Superoxide Dismutase
The autoxidation of pyrogallol was investigated in the presence of EDTA in the pH range 7.9–10.6. The rate of autoxidation increases with increasing pH. At pH 7.9 the reaction i...
