Stimulation of glucosyltransferase activity by the compatible solutes glycine betaine and trehalose. Assays were performed in the absence (○) or presence (•) of 50 mM potassium chloride. (A) Glycine betaine. The basal level of activity was 0.81 nmol of UDP-glucose converted to neutral product under standard reaction conditions. (B) Trehalose. The basal level of activity was 0.88 nmol of UDP-glucose converted to neutral product under standard reaction conditions.
