GLUT2 is coupled to this protein in the intestinal lumen. Phosphorylation of an aspartate in this protein's E1 configuration greatly increases its binding affinity.
GLUT2 is coupled to this protein in the intestinal lumen. Phosphorylation of an aspartate in this protein's E1 configuration greatly increases its binding affinity. Ouabain and digitalis competitively inhibit this protein; accordingly, it is targeted by cardiac glycosides to treat congestive heart failure. Jens Skou won the 1997 Nobel for characterizing this P-class enzyme. A ratio of (*) 2/3 is added to the Nernst equation to determine the potential created by this protein, which is about negative 60 millivolts in the resting state. This antiporter hydrolyzes ATP, causing a conformational shift that releases three ions into the cytosol. For 10 points, name this protein that transports alkali metal cations into and out of the cell through active transport.
