CC -!- FUNCTION: Polyprenyl transferase; part of the gene cluster that
CC mediates the biosynthesis of erinacines, cyathane-xylosides that show
CC unique biological activities, including leishmanicidal activity,
CC stimulating activity for nerve growth-factor synthesis, and agonistic
CC activity toward the kappa opioid receptor (PubMed:31535864). The
CC geranylgeranyl diphosphate (GGPP) synthase eriE catalyzes the first
CC step in erinacines biosynthesis via conversion of farnesyl
CC pyrophosphate and isopentyl pyrophosphate into geranylgeranyl
CC pyrophosphate (GGPP) (PubMed:31535864). GGPP is then substrate of the
CC diterpene cyclase eriG for the production of cyatha-3,12-diene
CC (PubMed:28371074). EriG is unable to use geranyl diphosphate (GPP) or
CC farnesyl diphosphate (FPP) as substrates (PubMed:28371074). The
CC cytochrome P450 monooxygenase eriI then hydroxylates cyatha-3,12-diene
CC at C-14 of the seven-membered ring to produce erinacol, which is
CC further hydroxylated at C-15 by the cytochrome P450 monooxygenase eriC
CC to yield cyathadiol (PubMed:31535864). The cytochrome P450
CC monooxygenase eriA then catalyzes C-11 hydroxylation in the presence of
CC the short chain dehydrogenase/reductase (SDR) eriH, which leads to the
CC production of cyathatriol (PubMed:31535864). The acetyltransferase eriL
CC converts cyathatriol into 11-O-acetyl-cyathatriol (PubMed:31535864).
CC The SDR eriH catalyzes further oxidation of 11-O-acetyl-cyathatriol
CC into 1-O-acetylcyathin A3 (PubMed:31535864). Finally, the glycosyl
CC transferase eriJ tranfers xylose from UDP-xylose onto C-14 of 11-O-
CC acetyl-cyathatriol to form eracine Q (PubMed:31535864). EriJ is also
CC able to convert 11-O-acetyl-cyathatriol to eracine Q2 by using UDP-D-
CC glucose as cosubstrate, but at a lower rate (PubMed:31535864). In the
CC absence of eriL and eriJ, the SDR eriH is able to convert cyathatriol
CC to cyathin A3; this is likely a switching mechanism in the biosynthesis
CC of cyathins (C-14 ketogroup)and erinacines (C-14 glycosylated group)
CC (PubMed:31535864). The roles of the SDR eriB, the polyprenyl
CC transferase eriF and the dehydrogenase eriK have still to be identified
CC (Probable). {ECO:0000269|PubMed:28371074, ECO:0000269|PubMed:31535864,
