 Title    Evidence for Photoreduction of NADP + in a Suspension of Lysed Plastids from Etiolated Bean Leaves  
 Abstract    It has been investigated if photoreduction of NADP + (detected by absorption spectroscopy) may take place in lysed plastids within minutes of exposure to light. This process was made possible by removal of oxidants from the reaction mixture. Lysed plastids were suspended in a medium containing NADP + , catalase, glucose oxidase and glucose; exposure to light simultane-ously to addition of ferredoxin and ferredoxin-NADP + reductase, resulted in increased absorb-ance in the band around 340 nm, while addition of 3-phosphoglycerate resulted in the disappear-ance of this band. Ferredoxin and ferredoxin-NADP + reductase are only effective when photo-activation takes place before their addition to the medium.
