CC   -!- FUNCTION: Dehydratase; part of the gene cluster that mediates the
CC       biosynthesis of iso-A82775C, a enylepoxycyclohexane and biosynthetic
CC       precursor of the chloropestolide anticancer natural products
CC       (PubMed:29384350). Within the cluster, the prenyltransferase iacE
CC       prenylates siccayne to generate pestalodiol E, using dimethylallyl
CC       diphosphate (DMAPP) as cosubstrate (PubMed:29384350). The probable
CC       oxidoreductase iacF is then involved in the epoxidation of pestalodiol
CC       F to pestalodiol F, which is further converted to pestalofone A by the
CC       short-chain dehydrogenase/reductase iacG (PubMed:29384350). Iso-A82775C
CC       is subsequently generated from pestalofone A by the short-chain
CC       dehydrogenase/reductase iacC (PubMed:29384350). Iso-A82775C is further
CC       condensed with maldoxin via a Diels-Alder reaction to produce the
CC       anticancer natural products chloropestolides A to E (Probable).
CC       {ECO:0000269|PubMed:29384350, ECO:0000305|PubMed:29384350}.
CC   -!- PATHWAY: Secondary metabolite biosynthesis.
CC       {ECO:0000305|PubMed:29384350}.
CC   -!- INDUCTION: Expression is co-regulated with the other genes from the
CC       iso-A82775C biosynthesis cluster and probably controlled by the
CC       cluster-specific transcription factors iacI and iacK.
CC       {ECO:0000269|PubMed:29384350}.
CC   -!- DISRUPTION PHENOTYPE: Reduces slightly the production of iso-A82775C.
CC       {ECO:0000269|PubMed:29384350}.
CC   -!- BIOTECHNOLOGY: Iso-A82775C is a precursor for the biosynthesis of the
CC       anticancer natural products chloropestolides A to E via a Diesls-Alder
CC       reaction with maldoxin (PubMed:29384350). In the absence of the
CC       prenyltransferase iacE, siccayne accumulates instead of iso-A82775C and
CC       can also be condensed with maldoxin to produce chloropestolides H to K,
CC       which show also antibacterial and anticancer properties
CC       (PubMed:29384350). {ECO:0000269|PubMed:29384350}.
CC   -!- SIMILARITY: Belongs to the tpcK family. {ECO:0000305}.
