【Abstract】 Superoxide dismutase(SOD) is an important antioxidase in living creature,existing widely in cytoplasm,mitochondria and chloroplast of eukaryotic and prokaryotic cells,and it can efficiently eliminate superoxide free anion radicals in organism,and prevent organism damage from superoxide free anion radicals.This paper summarizes the research advances on hydrobios(eg.fishes,shrimps,shellfishes and algaes) superoxide dismutase in terms of types,distribution,structural characteristics,physicochemical properties and gene cloning and expression.Meanwhile,the prospect of its application is also forecasted.更多还原
