A one-pot chemoenzymatic synthesis for the universal precursor of antidiabetes and antiviral bis-indolylquinones.
Schneider P., Weber M., Rosenberger K., Hoffmeister D.

Bis-indolylquinones represent a class of fungal natural products that display antiretroviral, antidiabetes, or cytotoxic bioactivities. Recent advances in Aspergillus genomic mining efforts have led to the discovery of the tdiA-E-gene cluster, which is the first genetic locus dedicated to bis-indolylquinone biosynthesis. We have now genetically and biochemically characterized the enzymes TdiA (bis-indolylquinone synthetase) and TdiD (L-tryptophan:phenylpyruvate aminotransferase), which, together, confer biosynthetic abilities for didemethylasterriquinone D to Aspergillus nidulans. This compound is the universal intermediate for all bis-indolylquinones. In this biochemical study of a bis-indolylquinone synthetase and a fungal natural product transaminase, we present a one-pot chemoenzymatic protocol to generate didemethylasterriquinone D in vitro. As TdiA resembles a nonribosomal peptide synthetase, yet catalyzes carbon-carbon-bond formation, we discuss the implications for peptide synthetase chemistry. << Less

Terrequinone A biosynthesis through L-tryptophan oxidation, dimerization and bisprenylation.
Balibar C.J., Howard-Jones A.R., Walsh C.T.
The antitumor fungal metabolite terrequinone A, identified in extracts of Aspergillus sp., is biosynthesized by the five-gene cluster tdiA-tdiE.

The antitumor fungal metabolite terrequinone A, identified in extracts of Aspergillus sp., is biosynthesized by the five-gene cluster tdiA-tdiE. In this work, we have overproduced all five proteins (TdiA-TdiE) in the bacterial host Escherichia coli, fully reconstituting the biosynthesis of terrequinone A. This pathway involves aminotransferase activity, head-to-tail dimerization and bisprenylation of the scaffold to yield the benzoquinone natural product. We have established that TdiD is a pyridoxal-5'-phosphate-dependent L-tryptophan aminotransferase that generates indolepyruvate for an unusual nonoxidative coupling by the tridomain nonribosomal peptide synthetase TdiA. TdiC, an NADH-dependent quinone reductase, generates the nucleophilic hydroquinone for two distinct rounds of prenylation by the single prenyltransferase TdiB. TdiE is required to shunt the benzoquinone away from an off-pathway monoprenylated species by an as yet unknown mechanism. Overall, we have biochemically characterized the complete biosynthetic pathway to terrequinone A, highlighting the nonoxidative dimerization pathway and the unique asymmetric prenylation involved in its maturation. << Less
