The aim of the work was to determine the tissue distribution, activity and polymorphism of 13 enzymes involved in antioxidative protection and xenobiotics biotransformation in a five bivalve mussel organs (hepatopancreas, ctenidia, mantle, leg, adductor muscles). Iso-allozyme analysis was performed by electrophoresis, correlation relationships between the studied enzymes in the whole mussel body were carried out using Spearman’s correlation analysis. It was found that all studied enzymes are polymorphic, each organ differed in the level of enzyme activity and a set of multiple forms. The coordinated functioning of protective enzymes in various mussel organs was demonstrated.
