title: Comparative Studies on Ferredoxin-NADP+ Oxidoreductase Isoenzymes Derived from Different Organs by Antibodies Specific for the Radish Root- and Leaf-Enzymes.
abstract: Determination of the prosthetic group and titration of sulfhydryl group of ferredoxin-NADP+ oxidoreductase (FNR) from roots of radish (Raphanus sativus var acanthiformis cv Miyashige) confirmed its similarity to leaf-FNR. Antisera directed against radish root-FNR and leaf-FNR distinguished the enzyme forms from roots and leaves of radish as well as other flowering plants. The FNR isoenzymes showed organ-specific distributions. In horsetail (Equisetum arvense L.) and cultured liverwort cells (Marchantia polymorpha), at least two FNR isoenzymes were distinguished by the antisera. FNR from Chlorella vulgaris reacted only with the anti-root-FNR antiserum. FNR from a cyanobacterium, Spirulina spp., failed to react with either antiserum.
