Inhibition of glucosyltransferase activity in wild-type, TY24, and LI1 membrane preparations by potassium chloride. Assays with membrane preparations from the wild-type (•), TY24 (⧫), and LI1 (○) strains were performed in the presence of potassium chloride at the concentrations indicated. The basal levels of activity for wild-type, TY24, and LI1 membrane preparations were 1.24, 0.29, and 1.32 nmol of UDP-glucose converted to neutral product under standard reaction conditions, respectively.
