Thanks very helpful for getting my glycogen synthase a (active, dephosphorylated), and glycogen phosphorylase a (active, phosphorylated) info straight before my midterm in exercise physio grad school :)
I am not sure how important this is but at U of M Medical School they teach Glycogenin is a substrate protein, not an enzyme necessarily. Glycogenin has the unusual property of catalyzing its own glycosylation, attaching C-1 of a UDP-glucose to a tyrosine residue on the enzyme. The attached glucose then serves as the primer required by glycogen synthase to attach additional glucose molecules via the mechanism described below. Anyway, just to add more detail or clear it up a little.
They didn't even touch this stuff after spending all this time learning it on the test. Instead he asked minutia from the articles...
