Phosphoribosylpyrophosphate in erythrocytes of ten mammalian species: concentration, synthesis and degradation
Comp Biochem Physiol B.
1978.
Abstract
1. The concentration of PRPP and the activity of PRPP synthetase have been measured in hemolysates from man and nine other mammalian species. PRPP synthetase activity was very low in dog hemolysate. 2. High concentrations of PRPP appeared to be associated with low levels of HGPRT activity, suggesting that HGPRT is the major pathway for utilization of PRPP in mammalian erythrocytes. 3. An alternative catabolic route for PRPP was observed in mammalian hemolysates, which seemed to be associated with acid phosphatase activity. The activity of acid phosphatase in mammalian hemolysates was measured.
