CC -!- FUNCTION: Trans-enoyl reductase; part of the gene cluster that mediates
CC the biosynthesis of a tyrosine-derived cytochalasan acting as a fungal
CC signal recognized by resistant rice plants and leads to avirulence in
CC Pi33 resistant rice cultivars (PubMed:18433432). The first step in the
CC pathway is catalyzed by the hybrid PKS-NRPS ACE1, assisted by the enoyl
CC reductase RAP1, that are responsible for fusion of the tyrosine
CC precursor and the polyketide backbone (PubMed:29142718). The polyketide
CC synthase module (PKS) of ACE1 is responsible for the synthesis of the
CC polyketide backbone and the downstream nonribosomal peptide synthetase
CC (NRPS) amidates the carboxyl end of the polyketide with the tyrosine
CC precursor (PubMed:29142718). Because ACE1 lacks a designated
CC enoylreductase (ER) domain, the required activity is provided the enoyl
CC reductase RAP1 (PubMed:29142718). Reduction by the hydrolyase ORFZ,
CC followed by dehydration and intra-molecular Diels-Alder cyclization by
CC the Diels-Alderase ORF3 then yield the required isoindolone-fused
CC macrocycle (Probable). A number of oxidative steps catalyzed by the
CC tailoring enymes identified within the cluster, including cytochrome
CC P450 monooxygenases CYP1 to CYP4, the FAD-linked oxidoreductase OXR2
CC and the short-chain dehydrogenase/reductase OXR1, are further required
CC to afford the final cytochalasans that confer avirulence and which have
CC still to be identified (Probable). The monooxygenase CYP1 has been
CC shown to be a site-selective C-18 hydroxylase whereas the function of
CC CYP3 is the site-selective epoxidation of the C-6/C-7 olefin that is
CC present in some intermediate compounds (PubMed:31644300). Finally, SYN2
CC and RAP2 are not required for avirulence in Pi33 resistant rice
CC cultivars (PubMed:18433432). {ECO:0000269|PubMed:18433432,
CC ECO:0000269|PubMed:29142718, ECO:0000269|PubMed:31644300,
CC ECO:0000305|PubMed:18433432, ECO:0000305|PubMed:29142718}.
CC -!- PATHWAY: Secondary metabolite biosynthesis.
CC {ECO:0000305|PubMed:18433432}.
CC -!- SUBUNIT: Monomer. {ECO:0000250|UniProtKB:Q9Y7D0}.
CC -!- INDUCTION: Expressed exclusively during fungal penetration of host
CC leaves, the time point at which plant defense reactions are triggered.
CC {ECO:0000269|PubMed:18433432}.
CC -!- DISRUPTION PHENOTYPE: Does not impeair avirulence in Pi33 resistant
CC rice cultivars. {ECO:0000269|PubMed:18433432}.
CC -!- SIMILARITY: Belongs to the zinc-containing alcohol dehydrogenase
CC family. {ECO:0000305}.
