Fig. 8: Schematic presentation of a part of the aflatoxin (AF) biosynthesis pathway of A. parasiticus MRI410.

Due to a substitution within the aflL gene, which encodes the desaturase responsible for converting versicolorin B to versicolorin A, versicolorin B is mostly converted into group 2 aflatoxins. The known structures are based on Caceres et al.15. DMST, demethylsterigmatocystin.
