Variation in erythrocyte purine metabolism among mouse strains.
Erythrocytes of five strains of mice had ATP concentrations of ca 2.7 mumol/ml packed cells, while those of CBA mice were 23% lower, and those of BALB/C mice were 40% lower. The ratio of the concentrations of ATP and GTP were ca 3.3 in four strains but greater than 27 in three other strains. When erythrocytes from different mouse strains were incubated with radioactive precursors, appreciable strain differences were found in the apparent activities of adenine and hypoxanthine-guanine phosphoribosyltransferase, adenosine kinase, adenosine deaminase, guanine deaminase and xanthine oxidase. The activities of adenosine deaminase and guanine deaminase in sera of mice of different strains also varied.
