CC -!- FUNCTION: Cytochrome P450 monooxygenase; part of the gene cluster that
CC mediates the biosynthesis of aculins (PubMed:26374386). The pathway
CC begins with the synthesis of 6-methylsalicylic acid by the polyketide
CC synthase (PKS) acuA via condensation of acetate and malonate units
CC (PubMed:26374386). The 6-methylsalicylic acid decarboxylase acuB then
CC catalyzes the decarboxylation of 6-methylsalicylic acid to yield m-
CC cresol (also known as 3-methylphenol) (Probable). These first reactions
CC occur in the cytosol (By similarity). The intermediate m-cresol is then
CC transported into the endoplasmic reticulum where the cytochrome P450
CC monooxygenase acuC converts it to m-hydroxybenzyl alcohol, which is
CC further converted to gentisyl alcohol by the cytochrome P450
CC monooxygenase acuD (Probable). Gentisyl alcohol is further oxidized by
CC the oxidoreductase acuE that probably catalyzes hydroxylation of the
CC aromatic ring (Probable). The aromatic system might then be opened by
CC oxidation through a Baeyer-Villiger type of oxidation, which could be
CC catalyzed by acuF, with the carboxylic acid at C-1 subsequently reduced
CC to an aldehyde by acuG (Probable). Subsequently, a hemiacetal is
CC formed, before the dehydrogenase acuH would reduce the double bond
CC between C-4 and C-6 (Probable). Finally, keto-enol tautomerism results
CC in formation of aculinic acid, which exists as two diastereomers (both
CC R/S configurations at C-1) by non-enzymatic hemiacetal formation
CC (Probable). The carboxypeptidase acuI could be involved in the linking
CC of aculinic acid to an aculene A moiety produced by the aculene
CC biosynthesis cluster and which leads to the production of aculin A
CC (Probable). AcuI may also be involved in the attachment of proline to
CC aculinic acid to form epi-aculins A and B (Probable).
