in myosin b , mg2+-atpase activity was below one-tenth that of the plasma membrane atpase with the maximum activation at 1 . 10 ( -2 ) m mg2+ and ph 9.0 edta- and ca2+-activated atpase exhibited almost the same activity and the same kcl-dependence curve , i.e. , both atpases increased and increasing kcl concentration .
