CC -!- FUNCTION: Geranylgeranyl pyrophosphate synthase; part of the gene
CC cluster that mediates the biosynthesis of 15-deoxyoxalicine B
CC (PubMed:30090271). The first step of the pathway is the synthesis of
CC nicotinyl-CoA from nicotinic acid by the nicotinic acid-CoA ligase olcI
CC (PubMed:30090271). Nicotinyl-CoA is then a substrate of polyketide
CC synthase olcA to produce 4-hydroxy-6-(3-pyridinyl)-2H-pyran-2-one
CC (HPPO) which is further prenylated by the polyprenyl transferase olcH
CC to yield geranylgeranyl-HPPO (PubMed:30090271). Geranylgeranyl
CC pyrophosphate is provided by the cluster-specific geranylgeranyl
CC pyrophosphate synthase olcC (PubMed:30090271). The FAD-dependent
CC monooxygenase olcE catalyzes the epoxidation of geranylgeranyl-HPPO and
CC the terpene cyclase olcD catalyzes the cyclization of the terpenoid
CC component, resulting in the formation of the tricyclic terpene moiety
CC seen in predecaturin E (PubMed:30090271). The cytochrome P450
CC monooxygenase then catalyzes the allylic oxidation of predecaturin E,
CC which is followed by spirocylization with concomitant loss of one
CC molecule of water to form decaturin E (PubMed:30090271). Decaturin E is
CC the substrate of the cytochrome P450 monooxygenase olcJ which
CC hydroxylates it at the C-29 position to form decaturin F
CC (PubMed:30090271). The short-chain dehydrogenase/reductase olcF may
CC catalyze the oxidation of decaturin F to generate the 29-hydroxyl-27-
CC one intermediate, and subsequent hemiacetal formation probably leads to
CC the formation of decaturin C (Probable). The dioxygenase olcK may be a
CC peroxisomal enzyme that catalyzes the hydroxylation of decaturin C into
CC decaturin A once decaturin C is shuttled into the peroxisome by the MFS
CC transporter olcL (Probable). Finally the cytochrome P450 monooxygenase
CC olcB catalyzes the oxidative rearrangement to yield 15-deoxyoxalicine B
CC (PubMed:30090271). In the absence of olcJ, decaturin E may be shunted
CC to a pathway in which it is oxidized to a ketone, possibly by olcF, to
CC form decaturin D, which undergoes further allylic oxidation to yield
CC decaturin G (PubMed:30090271). Moreover, in the absence of oclK or
CC oclL, oclB can convert decaturin C into 15-deoxyoxalicine A
CC (PubMed:30090271). {ECO:0000269|PubMed:30090271,

CC -!- DISRUPTION PHENOTYPE: Strongly decreases the production of 15-
CC deoxyoxalicine B. {ECO:0000269|PubMed:30090271}.
CC -!- MISCELLANEOUS: The 15-deoxyoxalicine B cluster is a rare cluster that
CC contains its own geranylgeranyl pyrophosphate synthase (olcC), in
CC contrast to other related clusters which rely on a FPP/GGPP synthase
CC localized outside of the cluster. {ECO:0000269|PubMed:30090271}.
CC -!- SIMILARITY: Belongs to the FPP/GGPP synthase family. {ECO:0000305}.
