SYNOPSIS.Tetrahymena pyriformis , strain HSM, do not have glucose‐6‐phosphate dehydrogenase or 6‐phosphogluconate dehydrogenase, but contain transaldolase, transketolase, ribose 5‐phosphate isomerase, ribulose‐5‐phosphate 3‐epimerase, and ribokinase. The nonoxidative enzymes of the pentose phosphate shunt function in metabolism as indicated by the incorporation of label from [1‐ 14 C]ribose into CO 2 and glycogen and by the increase in total glycogen content of cultures supplemented with ribose.
