Note on the comparison of calpains I, II and calpastatin activity in two different types of porcine skeletal muscles.
1. Activities of calpains I and II and calpastatin in two different types of porcine skeletal muscles were compared. 2. Semimembranosus muscle was composed of mixed fiber types with mainly glycolytic fibers (65%), while masseter muscle was composed exclusively of oxidative fibers. 3. Calpain I activity was lower and calpain II activity was higher in masseter muscle as compared to semimembranosus muscle. Calpastatin activities were similar in both muscles.
