Superoxide dismutase (SOD) is one of the key components of defense system, which protect cells and tissues from
oxidative destruction. The unique nature of this enzyme among other antioxidants, its localization in different
intracellular compartment are reviewed in addition to enzyme behaviour under unflavourable influences. Besides,
we considered questions of regulation of SOD activity, participation of such intracellular macromolecules as reactive
oxygen species, calcium iones, phytogormones, and nitric oxide in this regulation, as well as
phosphoralation/dephosphorylation process.
