Glycogen synthase, the enzyme that catalyzes the rate-limiting reaction of glycogen syntheses has been purified and characterized from Ascaris suum muscle. Glycogen in the crude extract was digested to release the enzyme, eluted from a DE52 cellulose column and then applied to a Sepharose affinity column. The purified Ascaris enzyme was found to be homologous to the mammalian enzyme with regard to subunit and holoenzyme Mr^3 allosteric activation, substrate affinity and covalent modification. However, the association between Ascaris glycogen synthase and endogenous glycogen differed from that in mammalian systems.
