coli xanthine-guanine phosphoribosyl transferase (gpt) gene has been used for positive selection in a purine salvage pathway as it catalyzes the conversion of xanthine, hypoxanthine and guanine to their respective monophosphates. Cells which express the gpt gene can utilize xanthine as a purine analog...
