Abstract

Superoxide dismutase (SOD) can be considered an antitoxic metalloenzyme that facilitates the production of oxygen and hydrogen peroxide from superoxide anions. Four classes have been identified depending on selective binding of metals, namely Cu,Zn-SOD, Fe-SOD, Mn-SOD, and Ni-SOD. The established isoforms are SOD1, SOD2, and SOD3 in various cells and tissues of eukaryotes. The relatively newer type Ni-SOD binds nickel and is observed in bacteria, including the genus Streptomyces. The Fe-SOD and Mn-SOD are also present in bacteria. Cu,Zn superoxide dismutase (SOD1) activity correlates with various pathophysiological states of organs. SOD2 binds manganese (Mn) and is located in the mitochondria. The SOD3, similar to the SOD1, binds copper and zinc, which are also expressed in the brain. The assay relies on several methods, including the enzyme activities, expression, field potential, and patch-clamp electrophysiology. The effects of SOD activity are emphasized at organ and whole-body levels depending on animal models. The antioxidant properties and behavior of SOD are compared based on responses among females and males to diet and toxic substances. However, in humans with amyotrophic lateral sclerosis (ALS), the mean SOD activity in both erythrocytes and muscles was comparable to controls. The detailed comparisons between the catalase and SOD activities are one of the aspects of this review. Also, modulation of excitability and synaptic plasticity in neurons by SOD is highlighted.

期刊介绍： Cell Biochemistry and Biophysics (CBB) aims to publish papers on the nature of the biochemical and biophysical mechanisms underlying the structure, control and function of cellular systems The reports should be within the framework of modern biochemistry and chemistry, biophysics and cell physiology, physics and engineering, molecular and structural biology. The relationship between molecular structure and function under investigation is emphasized. Examples of subject areas that CBB publishes are: · biochemical and biophysical aspects of cell structure and function; · interactions of cells and their molecular/macromolecular constituents; · innovative developments in genetic and biomolecular engineering; · computer-based analysis of tissues, cells, cell networks, organelles, and molecular/macromolecular assemblies; · photometric, spectroscopic, microscopic, mechanical, and electrical methodologies/techniques in analytical cytology, cytometry and innovative instrument design For articles that focus on computational aspects, authors should be clear about which docking and molecular dynamics algorithms or software packages are being used as well as details on the system parameterization, simulations conditions etc. In addition, docking calculations (virtual screening, QSAR, etc.) should be validated either by experimental studies or one or more reliable theoretical cross-validation methods.
