Studies on peroxidase isolated from etiolated Alaska pea seedlings I. General properties

Two kinds of peroxidase were isolated chromatographically frometiolated Alaska pea seedlings. One had absorption maxima at421 and 530 mµ, and the other, at 405, 500 and 640 mµ.From their affinities for cyanide and migrating patterns onelectrophoresis, the latter was concluded to be a modified formof the former. They were named peroxidase b and b', respectively.Both oxidized IAA, the optimal pH value for the reaction being3.0. (Received April 20, 1970; )
