Purine Phosphoribosylpyrophosphate Transferase In Chick Erythrocytes

Summary Hen erythrocytes were investigated with respect to their Purinphosphoribosyl-pyrophosphatetransferase activities. These enzyme systems connected within the salvage pathway of purines have a low activity in contrast to human erythrocytes or leucocytes. This is possibly due to xanthineoxydase, which is present in hen erythrocytes.
