UDP-glucose binding makes it easier for the enzyme to unfold.
The enzyme likely had phosphate groups added through covalent modification.
O Interactions with the bound UDP-glucose stabilize the tertiary structure of glycogen synthase.
The UDP-Glucose is a positíve effector which increases the enzyme activity.
