CC -!- FUNCTION: FAD-dependent monooxygenase; part of the gene cluster that
CC mediates the biosynthesis of chrodrimanin B, a meroterpenoid that acts
CC as a potent blocker of insect GABA-gated chloride channels
CC (PubMed:30417647). The first step of the pathway is the biosynthesis of
CC 6-hydroxymellein by the polyketide synthase cdmE (PubMed:30417647). The
CC prenyltransferase cdmH acts as a 6-hydroxymellein 5-farnesyltransferase
CC and produces the hydrophobic metabolite verruculide C
CC (PubMed:30417647). The FAD-dependent monooxygenase cdmI further
CC converts verruculide C into verruculide B (PubMed:30417647). The
CC terpene cyclase cdmG then produced the pentacyclic molecule 3-
CC hydroxypentacecilide A, the backbone structure of chrodrimanin B, via
CC folding the farnesyl moiety of the substrate into the chair-boat
CC conformation (PubMed:30417647). The short-chain dehydrogenase/reductase
CC cdmF functions as the 3-OH dehydrogenase that oxidizes the C-3 hydroxyl
CC group of 3-hydroxypentacecilide A and produces chrodrimanin C, the
CC dehydrogenated product of 3-hydroxypentacecilide A (PubMed:30417647).
CC The cytochrome P450 monooxygenase cdmJ then accepts both 3-
CC hydroxypentacecilide A and chrodrimanin C and functions as a C-7-beta-
CC hydroxylase to produce respectively chrodrimanin H and chrodrimanin F
CC (PubMed:30417647). The dioxygenase cdmA accepts chrodrimanin H to
CC afford chrodrimanin E, which is further transformed to chrodrimanin A
CC by the dioxygenase cdmD (PubMed:30417647). CdmA can also accept
CC chrodrimanin C as substrate to convert it into verruculide A, which is
CC further converted into chrodrimanin T by cdmD (PubMed:30417647). The
CC last step of the biosynthesis is proposed to be performed by the
CC acetyltransferase cdmC which acetylates chrodrimanin A to yield
CC chrodrimanin B (Probable). The pathway may also lead to the production
CC of additional shunt products, including chrodrimanins T and U
CC (PubMed:30417647). {ECO:0000269|PubMed:30417647,

CC -!- PATHWAY: Secondary metabolite biosynthesis; terpenoid biosynthesis.
CC {ECO:0000269|PubMed:30417647}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000255}; Single-pass membrane
CC protein {ECO:0000255}.
CC -!- BIOTECHNOLOGY: Compounds in the chrodrimanin family such as
CC chrodrimanin A or verruculide A exhibit strong inhibitory activities
CC against protein tyrosine phosphatase 1B (PTP1B) and therefore, they
CC could potentially be developed into drugs for the treatment of type 2
CC diabetes or obesity (PubMed:26115570). Furthermore, chrodrimanin B, the
CC end product of the pathway involving chrodrimanin A or verruculide A,
CC does not exhibit the PTP1B inhibitory activity, while it functions as a
CC potent blocker of insect GABA-gated chloride channels
CC (PubMed:25902139). {ECO:0000269|PubMed:25902139,
CC ECO:0000269|PubMed:26115570}.
CC -!- SIMILARITY: Belongs to the paxM FAD-dependent monooxygenase family.
CC {ECO:0000305}.
