title: Production of aromatic minimal polyketides by the daunorubicin polyketide synthase genes reveals the incompatibility of the heterologous DpsY and JadI cyclases.
abstract: Our investigations into whether the biosynthesis of a linearly fused ring system of an aromatic polyketide (jadomycin) could be modified to produce an angularly fused system (daunorubicin) and vice versa showed that introduction of the respective cyclases did not have the desired effect. Genes from the daunorubicin pathway produced a novel 21-carbon polyketide.
