Activities of superoxide dismutase and catalase in the foot of three freshwater mussel species

The aim of our experiments was to determine the activities of total superoxide dismutase (Tot SOD, EC 1.15.1.1), copper and zinc-containing superoxide dismutase (CuZn SOD), manganese-containing superoxide dismutase (Mn SOD), and catalase (CAT, EC 1.11.1.6) in the foot of three freshwater mussel species: Unio pictorum, Unio tumidus, and Sinanodonta woodiana. The first two species are native to Serbian freshwaters, but S. woodiana is an invasive species originating form Eastern Asia. The specimens (n=30, 10 of each freshwater mussel species) were collected from the river Sava, near Sabac (Serbia), during August, 2006.
