| Abstract |
1. The subcellular location of superoxide dismutase in the leaves of spinach and other C3 plants has been investigated. 2. Most activity appeared to be located within chloroplasts. These organelles contain a cyanide-sensitive (copper-zinc) superoxide dismutase, most of which is located in the stroma although some is bound to the thylakoids. 3. Intact chloroplast fractions also contain a cyanide-insensitive (manganese) superoxide dismutase, but this activity is located on the outside of the chloroplasts and may be adsorbed onto them during isolation. 4. Leaf mitochondrial fractions contain only a small percentage of total leaf superoxide dismutase activity, but there is more than can be accounted for by contamination with chloroplasts. 5. Mitochondria contain both a cyanide-sensitive dismutase, apparently located in the intermembrane space, and a cyanide-insensitive activity, apparently located in the matrix. 6. The microsomal fraction contains no superoxide dismutase activity. |
