[Peroxidase activity of the influenza virus]

The appearance of chemiluminescence has been detected in influenza virus-luminol-hydrogen peroxide system. An effective decrease of its intensity in the presence of oxygen radical scavengers (sodium azide, superoxide dismutase, mannitol, ethanol) is indicative of activated oxygen taking part in the reaction. Increased luminescence in the presence of o-phenanthroline and its suppression by antimycin A suggest that peroxidase-like activity of influenza virus is due to the presence in it of Fe-S-protein.
