The conformations of a functional spin-labeled derivative of gastric H/K-ATPase investigated by EPR spectroscopy.
A spin-labeled derivative of porcine gastric H/K-ATPase with high ATP hydrolyzing activity (77 mumol of Pi/(mg.h)) has been prepared. Over 65% of initial ATPase activity (115 mumol of Pi/(mg.h)) was preserved after complete reaction of the enzyme with the lysine reactive nitroxide spin-labeled TEMPO...
