Enzyme: Crystal Structure of Wild-Type Human Phosphoglucomutase-1 (PGM1)

How does the enzyme carry out its function (e.g., enzymatic reaction)? Does it need coenzymes or cofactors? You will also show the chemical reaction(s) the enzyme carries out including the involvement of coenzymes/cofactors. Describe the type of chemical reaction (e.g., hydrolysis, isomerization, redox, elimination, etc.) carried out by the enzyme. The description should closely be tied to the diagram representing the chemical reaction. What is the relevance of this chemical reaction in a bigger context, e.g., in the context of the pathway or cellular mechanism?
