    摘要: We reannotated the A. niger NR-PKS gene, e_gw1_19.204, and its downstream R domain gene, est_GWPlus_C_190476, as a single gene which we named dtbA. Heterologous expression of dtbA In A. nidulans demonstrated that DtbA protein produces two polyketides, 2,4-dihydroxy-3,5,6-trimethylbenzaldehyde (1) and 6-ethyl-2,4-dihydroxy-3,5-dimethylbenzaldehyde (2). Generation of DtbA Delta R+TE chimeric PKSs by swapping the DtbA R domain with the AusA (austinol biosynthesis) or ANID_06448 TE domain enabled the production of two metabolites with carboxylic acids replacing the corresponding aldehydes.
