Putative acetyltransferase; part of the gene cluster that mediates the biosynthesis of butenolide, a mycotoxin that shows antibiotic activity but does not seem to play a major role in the spread of head blight in wheat (PubMed:17175185). Butenolide is derived from glutamic acid via a 4-acetamido-2-butenoic acid intermediate (Probable). The predicted function of the NADH:flavin oxidoreductase FG08077, the cytochrome P450 monooxygenase FG08079, the decarboxylase FG08083, and the putative acetyltransferase FG08082 are consistent with this pathway, however, the respective activities of the butelonide biosynthesis cluster enzymes have still to be experimentally determined (Probable). Mycotoxin biosynthesis. Highly expressed under trichothecene-producing conditions. Belongs to the acetyltransferase family.
