Fumarase activity in skeletal muscle of man.
Soluble extracts of human skeletal muscle have a fumarase activity of 31.2 +/- 7.27 (M. vastus lateralis quadricipitis) or 30.9 +/- 8.0 U/g wet weight at 37 degrees C (M. deltoideus). The distribution of activities in the 36 muscle samples studies is not gaussian. There is a significant correlation between the activities of citrate synthase and fumarase (r = + 0.881; p less than 0.001) in all investigated muscles, excepting M. vastus lateralis quadricipitis.
