Abstract:
The glycogen phosphorylase of Tetrahymena pyriformis complexes with glycogen as judged by its elution pattern from columns of Sepharose 6B. Complex formation does not occur with starch, amylose, or amylopectin, and neither do these polyglucans serve as primers for the enzyme. To study the association between the phosphorylase and glycogen particles in situ, Tetrahymena were grown under differing physiological conditions, phosphorylase was isolated and chromatographed on a Sepharose 6B column. Phosphorylase activity isolated from cells grown in the absence of glucose was only partially associated with glycogen, while in cells exposed to glucose for 30 min or more all the phosphorylase activity was associated with glycogen. The effects of culture age and anaerobiosis on the relative amounts of free and glycogen-bound enzyme in the cells were also studied. It was concluded from the in vivo experiments that there was no simple relation between the fraction of enzyme bound to glycogen and between cell glycogen content. © 1971.
