Enzyme Function FUNCTION: Part of the core gene cluster that mediates the biosynthesis of trichothecenes, a very large family of chemically related bicyclic sesquiterpene compounds acting as mycotoxins, including T2-toxin (PubMed:11352533). The biosynthesis of trichothecenes begins with the cyclization of farnesyl diphosphate to trichodiene and is catalyzed by the trichodiene synthase TRI5 (PubMed:3800398). Trichodiene undergoes a series of oxygenations catalyzed by the cytochrome P450 monooxygenase TRI4 (PubMed:7651333). TRI4 controls the addition of four oxygens at C-2, C-3, C-11, and the C-12, C-13-epoxide to form the intermediate isotrichotriol (PubMed:16917519). Isotrichotriol then undergoes a non-enzymatic isomerization and cyclization to form isotrichodermol (PubMed:2317042). During this process, the oxygen at the C-2 position becomes the pyran ring oxygen and the hydroxyl group at C-11 is lost (PubMed:2317042). More complex type A trichothecenes are built by modifying isotrichodermol through a series of paired hydroxylation and acetylation or acylation steps (PubMed:11352533). Isotrichodermol is converted to isotrichodermin by the acetyltransferase TRI101 (PubMed:10583973). TRI101 encodes a C-3 transacetylase that acts as a self-protection or resistance factor during biosynthesis and that the presence of a free C-3 hydroxyl group is a key component of Fusarium trichothecene phytotoxicity (PubMed:10583973). A second hydroxyl group is added to C-15 by the trichothecene C-15 hydroxylase TRI11, producing 15-decalonectrin, which is then acetylated by TRI3, producing calonectrin (PubMed:9435078, PubMed:8593041). A third hydroxyl group is added at C-4 by the cytochrome P450 monooxygenase TRI13, converting calonectrin to 3,15-diacetoxyspirpenol, which is subsequently acetylated bythe acetyltransferase TRI7 (PubMed:12135578, PubMed:11352533). A fourth hydroxyl group is added to C-8 by the cytochrome P450 monooxygenase TRI1, followed by the addition of an isovaleryl moiety by TRI16 (PubMed:12620849, PubMed:14532047). Finally, the acetyl group is removed from the C-3 position by the trichothecene C-3 esterase TRI8 to produce T-2 toxin (PubMed:12039755). {ECO:0000269|PubMed:10583973, ECO:0000269|PubMed:11352533, ECO:0000269|PubMed:12039755, ECO:0000269|PubMed:12135578, ECO:0000269|PubMed:12620849, ECO:0000269|PubMed:14532047, ECO:0000269|PubMed:16917519, ECO:0000269|PubMed:2317042, ECO:0000269|PubMed:3800398, ECO:0000269|PubMed:7651333, ECO:0000269|PubMed:8593041, ECO:0000269|PubMed:9435078}.
