Why is adenine toxic?
Growth studies with various purine salvage pathway mutants and the ability of guanosine to prevent adenine toxicity indicated that adenine exerts its toxic effects by depleting guanine nucleotide pools. In the presence of adenine, ATP pools increased twofold in wild-type cells and stabilized after 5 min.
