Quantification data of isotopomers of the biosynthetic intermediates and the shunt product in A. catenella cultured in 15N-NaNO3. Concentrations in culture (nM) for the each isotopomer of samples from 0, 3, 6, and 10 days (n = 3 for each day) after addition of 15N-labelled sodium nitrate-containing medium were calculated after removing the contribution of the naturally occurring stable isotope. The precursor: arginine, biosynthetic intermediates: Int-A’, Int-C’2, 11-hydroxy-Int-C’2, Int-E’ and the shunt product: Cyclic-C’.
