• Crystalline cytochrome c-553 was obtained from Porphyra yezoensis Ueda. The cytochrome in a reduced form was modified to show a nitrite-reducing activity after appropriate treatment with heat, hydrogen peroxide, or photooxidation using methylene blue as the electron acceptor, but the reducing activity was far lower than that of the nitrite reductase isolated from this alga. The modified cytochrome c-553 was autooxidizable and showed an absorption spectrum resembling that of cytochrome c-553 in the oxidized form except for slight shifts of the absorption maximum in the γ-band region toward shorter wavelengths.
