2 Introduction 3 Phylogenetic distribution and subcellular localization 3 Kinetics and mechanism 3 Molecular and chemical structure 5 Biological significance 8 Summary 9 References 10 Abstract Manganese superoxide dismutase (MnSOD) is the primary antioxidant enzyme that protects cells from oxidative stress by catalyzing dismutation of superoxide (O2 ) to hydrogen peroxide and oxygen in the mito...
متن کاملIsolation, chromosomal localization, and differential expression of mitochondrial manganese superoxide dismutase and chloroplastic copper/zinc superoxide dismutase genes in wheat.
Superoxide dismutase (SOD) gene expression was investigated to elucidate its role in drought and freezing tolerance in spring and winter wheat (Triticum aestivum). cDNAs encoding chloroplastic Cu/ZnSODs and mitochondrial MnSODs were isolated from wheat. MnSOD and Cu/ZnSOD genes were mapped to the long arms of the homologous group-2 and -7 chromosomes, respectively. Northern blots indicated that...

متن کاملManganese Superoxide Dismutase: Guardian of the Powerhouse
The mitochondrion is vital for many metabolic pathways in the cell, contributing all or important constituent enzymes for diverse functions such as β-oxidation of fatty acids, the urea cycle, the citric acid cycle, and ATP synthesis. The mitochondrion is also a major site of reactive oxygen species (ROS) production in the cell. Aberrant production of mitochondrial ROS can have dramatic effects ...
متن کاملThe irony of manganese superoxide dismutase.
The manganese and iron SODs (superoxide dismutases) form a superfamily of closely related antioxidant defence metalloenzymes. MnSOD requires Mn (not Fe) for activity. However, when MnSOD is expressed in Escherichia coli grown in medium supplemented with ferrous salts, Fe substitutes for Mn in the active site, reflecting relatively indiscriminate uptake of either Mn or Fe and a surprisingly low ...
