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

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 wax synthase family. {ECO:0000305}.
