Electron-spin-resonance spectra of spinach phosphodoxin and spinach chloroplasts

Abstract

It has been found that: the dark electron-spin-resonance spectrum of spinach chloroplast fragments is reduced in the presence of spinach phosphodoxin; the light-induced electron-spin-resonance spectrum of spinach chloroplast fragments is increased in the presence of spinach phosphodoxin; and spinach phosphodoxin alone exhibits a pH-dependent, light-induced spin signal.
