Transcription factor; part of the gene cluster that mediates the biosynthesis of enfumafungin, a glycosylated fernene-type triterpenoid with potent antifungal activity, mediated by its interaction with beta-1,3-glucan synthase and the fungal cell wall (PubMed:30051576). Is possibly responsible for the transcription regulation of one or more genes within the gene cluster (Probable). Belongs to the TFIIE alpha subunit family.
