CC   -!- FUNCTION: Methyltransferase; part of the gene cluster that mediates the
CC       biosynthesis of trypacidin, a mycotoxin with antiprotozoal activity and
CC       that plays a role in the infection process (PubMed:26278536,
CC       PubMed:26242966). The pathway begins with the synthesis of atrochrysone
CC       thioester by the polyketide synthase (PKS) tpcC (PubMed:26242966). The
CC       atrochrysone carboxyl ACP thioesterase tpcB then breaks the thioester
CC       bond and releases the atrochrysone carboxylic acid from tpcC
CC       (PubMed:26242966). The decarboxylase tpcK converts atrochrysone
CC       carboxylic acid to atrochrysone which is further reduced into emodin
CC       anthrone (PubMed:26242966). The next step is performed by the emodin
CC       anthrone oxygenase tpcL that catalyzes the oxidation of emodinanthrone
CC       to emodin (PubMed:26242966). Emodin O-methyltransferase encoded by tpcA
CC       catalyzes methylation of the 8-hydroxy group of emodin to form questin
CC       (PubMed:26242966). Ring cleavage of questin by questin oxidase tpcI
CC       leads to desmethylsulochrin via several intermediates including questin
CC       epoxide (By similarity). Another methylation step catalyzed by tpcM
CC       leads to the formation of sulochrin which is further converted to
CC       monomethylsulfochrin by tpcH. Finally, the tpcJ catalyzes the
CC       conversion of monomethylsulfochrin to trypacidin (PubMed:26242966).
CC       Trypacidin is toxic for human pulmonary and bronchial epithelial cells
CC       by initiating the intracellular formation of nitric oxide (NO) and
CC       hydrogen peroxide (H(2)O(2)), thus triggering host necrotic cell death
CC       (PubMed:22319557). The trypacidin pathway is also able to produce
CC       endocrocin via a distinct route from the endocrocin Enc pathway
CC       (PubMed:26242966). {ECO:0000250|UniProtKB:Q0CCX8,
CC       ECO:0000269|PubMed:22319557, ECO:0000269|PubMed:26242966,
CC       ECO:0000269|PubMed:26278536}.
CC   -!- PATHWAY: Secondary metabolite biosynthesis.
CC       {ECO:0000305|PubMed:26242966}.
CC   -!- TISSUE SPECIFICITY: Specifically expressed in conidia
CC       (PubMed:22319557). {ECO:0000305|PubMed:22319557}.
CC   -!- INDUCTION: Expression is positively regulated by the transcription
CC       factors brlA and laeA (PubMed:26242966). {ECO:0000269|PubMed:26242966}.
CC   -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC       superfamily. {ECO:0000305}.
