Incorporation of δ-aminolaevulinic acid 514C and 414C into the inosine monophosphate pool and into porphyrins, was studied in cell suspensions ofR. spheroides. The results contradict a direct incorporation of δ-aminolaevulinic acid into the purine ring of nucleotides through λδ-dioxovaleric acid. It would suggest a nonspecific incorporation after degradation of δ-aminolaevulinic acid without a transamination as a first reaction.
