CC -!- FUNCTION: Short-chain dehydrogenase; part of the gene cluster that
CC mediates the biosynthesis of sordarial, a salicylic aldehyde
CC structurally related to the phytotoxin pyriculol (PubMed:19277664,
CC PubMed:28485098, PubMed:30908040). The most interesting aspect of this
CC pathway is formation of an aromatic product from the highly reducing
CC polyketide synthase srdA (PubMed:30908040). SrdA synthesizes a reduced
CC polyketide chain from one molecule of acetyl-CoA and five molecules of
CC malonyl-CoA (PubMed:30908040). The polyketide chain is then reductively
CC released as an aldehyde (PubMed:30908040). The oxidoreductases srdC,
CC srdD and srdE then oxidize one of the hydroxy groups to facilitate the
CC intramolecular aldol condensation, followed by dehydration to yield a
CC salicylic aldehyde (PubMed:30908040). This aldehyde can undergo facile
CC reduction by endogenous reductases to yield the alcohol 1-hydroxy-2-
CC hydroxymethyl-3-pent-1,3-dienylbenzene (PubMed:30908040). The flavin-
CC dependent srdI counteract against the propensity of the aldehydes to be
CC reduced under physiological conditions and is responsible for
CC reoxidizing 1-hydroxy-2-hydroxymethyl-3-pent-1,3-dienylbenzene back to
CC the salicylic aldehyde (PubMed:30908040). This salicylic aldehyde is
CC then selectively epoxidized by the cupin-domain-containing
CC oxidoreductase srdB to yield the epoxide, which can be hydrolyzed
CC stereoselectively by the hydrolase srdG to give the final product
CC sordarial (PubMed:30908040). {ECO:0000269|PubMed:19277664,
CC ECO:0000269|PubMed:28485098, ECO:0000269|PubMed:30908040}.
CC -!- INDUCTION: Expression is up-reglated during sexual development
CC (PubMed:19277664). Expression is also up-reglated during confrontation
CC with the arthropod fungivore Drosophila melanogaster (PubMed:28485098).
CC {ECO:0000269|PubMed:19277664, ECO:0000269|PubMed:28485098}.
CC -!- SIMILARITY: Belongs to the short-chain dehydrogenases/reductases (SDR)
CC family. {ECO:0000305}.
CC -!- CAUTION: A recent genetics report associated srdA and its cluster with
CC the biosynthesis of furanocoumarin neurosporin A, a metabolite produced
CC by N.crassa for chemoresistance against predation by arthropod
CC fungivores (PubMed:28485098). However, based on the gene cluster
CC organization and predicted gene functions, this cluster is unlikely to
CC be involved in neurosporin A biosynthesis, but instead produces
CC compounds similar to pyriculol (PubMed:30908040).
