CC -!- FUNCTION: Aldolase; part of the gene cluster that mediates the
CC biosynthesis of viridicatumtoxin, a tetracycline-like fungal
CC meroterpenoid with a unique, fused spirobicyclic ring system
CC (PubMed:20534346). The first step of the pathway is the production of
CC the malonamoyl-CoA starter unit for the polyketide synthase vrtA
CC (PubMed:20534346). The aldolase vrtJ may be involved in the synthesis
CC of the malonamate substrate for malonamoyl-CoA synthetase vrtB
CC (PubMed:20534346). The polyketide synthase vrtA then may utilize the
CC malonamoyl-CoA starter unit, followed by sequential condensation of
CC eight malonyl-CoA units to form the polyketide backbone
CC (PubMed:20534346). The cyclization of the last ring could be mediated
CC by the lactamase-like protein vrtG (PubMed:20534346). The proposed
CC post-PKS tailoring steps are an hydroxylation at C5 catalyzed the
CC cytochrome P450 monooxygenase vrtE, a hydroxylation at C12a catalyzed
CC by VrtH and/or VrtI, and an O-methylation by the O-methyltransferase
CC vrtF (PubMed:20534346, PubMed:24161266). VrtC is then proposed to
CC catalyze the transfer of a geranyl group synthesized by vrtD to the
CC aromatic C ring of the tetracyclic polyketide intermediate of
CC viridicatumtoxin to yield previridicatumtoxin (PubMed:20534346).
CC Finally, the cytochrome P450 monooxygenase vrtK catalyzes the
CC spirocyclization of the geranyl moiety of previridicatumtoxin to afford
CC viridicatumtoxin (PubMed:24161266). {ECO:0000269|PubMed:20534346,

CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000250|UniProtKB:O07051};
CC -!- PATHWAY: Secondary metabolite biosynthesis; terpenoid biosynthesis.
CC {ECO:0000269|PubMed:20534346}.
CC -!- BIOTECHNOLOGY: Viridicatumtoxin and its derivative, viridicatumtoxin B,
CC exhibit anti-methicillin-resistant Staphylococcus aureus (anti-MRSA)
CC activity (PubMed:19168978). Moreover, viridicatumtoxin and a C2 acetyl
CC analog, spirohexaline, have been demonstrated to inhibit bacterial
CC undecaprenyl diphosphate synthase, a potential new target for
CC antibiotic development (PubMed:27049441). {ECO:0000269|PubMed:19168978,
CC ECO:0000269|PubMed:27049441}.
CC -!- SIMILARITY: Belongs to the threonine aldolase family. {ECO:0000305}.
