title: Improved in vitro light activation and assay systems for two spinach chloroplast enzymes.
abstract: An improved system for the in vitro light activation of the chloroplast enzymes fructose-1,6-bisphosphatase and NADP-dependent malate dehydrogenase is described. Through the presence of the monothiol beta-mercaptoethanol in the reaction mixtures the activated forms of the enzymes can be stabilized and their activity determined spectrophotometrically.
