Question: what is the function of phosphoglucomutase in glycogen metabolism?
Answer: Phosphoglucomutase (EC 5.4. 2.2) is an enzyme that transfers a phosphate group on an α-D-glucose monomer from the 1' to the 6' position in the forward direction or the 6' to the 1' position in the reverse direction. More precisely, it facilitates the interconversion of glucose 1-phosphate and glucose 6-phosphate.
