Trans-enoyl reductase; part of the gene cluster that mediates the biosynthesis of fujikurins A-D, secondary metabolites playing a role during rice infection (PubMed:23825955, PubMed:26192387). The polyketide synthase PKS19 acts with the trans-enoyl reductase FFUJ_12240 and the polyketide transferase FFUJ_12241 to produce fujikurins, however, the biosynthesis pathway has not been identified yet (PubMed:23825955, PubMed:26192387). The fujikurins gene cluster is specifically expressed during rice infection (PubMed:23825955). Belongs to the zinc-containing alcohol dehydrogenase family.
