Thylakoid-bound superoxide dismutase (SOD; EC 1.15.1.1) was solubilized by Triton X-100 from spinach and purified to a homogeneous state. The molecular weight of thylakoid-bound SOD was 52000; the enzyme was composed of two equal subunits. Its activity was not sensitive to cyanide and hydrogen perox
Ion exchange perfusion chromatography has been teins requires the presence of detergent to solubilize introduced for the isolation of hydrophobic membrane the proteins from the lipid bilayer and to keep them protein complexes from thylakoid membranes of spinin solution during subsequent isolation.

Chloroplasts and thylakoids isolated from spinach were entrapped in six different polyvinylalcohol bearing styrylpyridium groups (PVA-SbQ). Measurements of oxygen production were carried out in 0.01 M phosphate buffer (pH 6) at 25" C. I~ob~~~ preparations were compared for their electron transport a
The precursors of the F1-ATPase fl-subunits from Nicotiana plumbaginifolia and Neurospora crassa were imported into isolated spinach (Spinacia oleracea L.) leaf mitochondria. Both Flfl precursors were imported and processed to mature size products. No import of the mitochondrial precursor proteins i
