Cytochalasin B binding sites and glucose transport carrier in human erythrocyte ghosts.

CytochalasinB was found to be a competitive inhibitor of the glucose carrier activity of human erythrocyte membrane preparations (K, = 2.6 to 4.0 x lo-' M).Among seven other cytochalasins tested, only cytochalasin A was effective (K, = 1 to 4 x lo-" M), indicating a stringent specificity of this inh...
