This entry includes a group of oxidoreductases, including AsaB from Aspergillus flavus [], Oxidoreductase R1/R2 from Phoma sp., DES from Gibberella fujikuroi, and Chry3 from Gibberella zeae. AsaB is involved in secondary metabolite biosynthesis. It converts aspergillic acid to hydroxyaspergillic acid []. R1/R2 is part of the gene cluster that mediates the biosynthesis of squalestatin S1 []. Chry3 is part of the gene cluster that mediates the biosynthesis of the yellow pigment chrysogine []. DES is part of the gene cluster that mediates the biosynthesis of gibberellins (GAs), diterpenoids that may provide a selective advantage during infection of the preferred host plant, rice [, , , , ].Proteins in this entry are related to RbtB and RbtG from Penicillium dangeardii. RbtB and RbtG are alpha-ketoglutarate-dependent dioxygenases involved in rubratoxin biosynthesis [].
