ON THE LIGHT-INDUCED BLEACHING OF PHOTOSYNTHETIC PYRIDINE NUCLEOTIDE REDUCTASE IN THE PRESENCE OF CHLOROPLASTS

Abstract
Light-dark difference spectra for PPNR reduction by illuminated chloroplasts, together with the kinetics of reduction of the pigment and its reduction of NADP, show that the pigment is a permissible intermediate in the photosynthetic pyridine nucleotide reductase activity.
