1. Neurospora crassa was found to contain two distinct superoxide dismutases. 2. Most of the activity is associated with the cytosolic fraction and was shown to be the Cu/Zn-containing form of the protein. 3. Mitochondria isolated from Neurospora crassa showed two distinct superoxide dismutases: a cyanide-sensitive Cu/Zn-containing protein and a(More)
A 23-amino-acid synthetic lytic peptide (Hecate) was covalently linked to magnetite nanoparticles and the lytic peptide-bound nanoparticles were characterized by X-ray absorption near-edge structure spectroscopy, transmission electron microscopy, and electron diffraction. Investigation of magnetic properties with a superconducting quantum interference(More)
1. Superoxide dismutase activity was present in the heterocysts and vegetative cells of Anabaena cylindrica, but was always lower in the heterocysts. 2. No qualitative differences were found in the superoxide dismutase from the two cellular types. 3. Catalase activity was also present in both cellular types. 4. Most of the NADP reductase activity, as(More)
The alteration in both the lipid composition and chlorophyll proteins obtained by sodium dodecyl sulfate-polyacrylamide gel electrophoresis of detergent solubilized thylakoids was investigated on differentially aged spinach (Spinacia oleracea L.) chloroplasts. Freshly isolated material demonstrated seven major bands upon electrophoretic fractionation.(More)
Superoxide dismutase has been studied in a wide range of organisms (Fridovich, 1975). Early observations suggested that superoxide dismutases isolated from eukaryotes (McCord & Fridovich, 1969; Misra & Fridovich, 1972; Beauchamp & Fridovich, 1973) showed little diversity in their properties, having mol.wts. near 32000 and containing two copper and two zinc(More)
