Abstract
A catalytic asymmetric nucleophilic reverse prenylation of indol-2-ones in situ generated from 3-bromooxindoles with prenyltributylstannane promoted by Ni(II)/chiral N,N'-dioxide was developed. This reaction provides facile access to C3 reverse-prenylated oxindoles in good to excellent enantioselectivities, which enabled the asymmetric synthesis of debromoflustramine A in five steps.

Abstract
Ribosomally synthesized and post-translationally modified peptide natural products have provided many highly unusual scaffolds. This includes the intriguing alkaloids crocagins, which possess a tetracyclic core structure and whose biosynthesis has remained enigmatic. Here we use in vitro experiments to demonstrate that three proteins, CgnB, CgnC and CgnE, are sufficient for the production of the hallmark tetracyclic crocagin core from the precursor peptide CgnA. The crystal structures of the homologues CgnB and CgnE reveal them to be the founding members of a peptide-binding protein family and allow us to rationalize their distinct functions. We further show that the hydrolase CgnD liberates the crocagin core scaffold, which is subsequently N-methylated by CgnL. These insights allow us to propose a biosynthetic scheme for crocagins. Bioinformatic analyses based on these data led to the discovery of related biosynthetic pathways that may provide access to a structurally diverse family of peptide-derived pyrroloindoline alkaloids.

Abstract
Covering: up to 2022Pyrroloindoline is a privileged tricyclic indoline motif widely present in many biologically active and medicinally valuable natural products. Thus, understanding the biosynthesis of this molecule is critical for developing convenient synthetic routes, which is highly challenging for its chemical synthesis due to the presence of rich chiral centers in this molecule, especially the fully substituted chiral carbon center at the C3-position of its rigid tricyclic structure. In recent years, progress has been made in elucidating the biosynthetic pathways and enzymatic mechanisms of pyrroloindoline-containing natural products (PiNPs). This article reviews the main advances in the past few decades based on the different substitutions on the C3 position of PiNPs, especially the various key enzymatic mechanisms involved in the biosynthesis of different types of PiNPs.

Abstract
Natural products from fungi represent an important source of biologically active metabolites notably for therapeutic agent development. Genome sequencing revealed that the number of biosynthetic gene clusters (BGCs) in fungi is much larger than expected. Unfortunately, most of them are silent or barely expressed under laboratory culture conditions. Moreover, many fungi in nature are uncultivable or cannot be genetically manipulated, restricting the extraction and identification of bioactive metabolites from these species. Rapid exploration of the tremendous number of cryptic fungal BGCs necessitates the development of heterologous expression platforms, which will facilitate the efficient production of natural products in fungal cell factories. Host selection, BGC assembly methods, promoters used for heterologous gene expression, metabolic engineering strategies and compartmentalization of biosynthetic pathways are key aspects for consideration to develop such a microbial platform. In the present review, we summarize current progress on the above challenges to promote research effort in the relevant fields.

Abstract
An expedient route to enantiopure, diastereomeric pyrrolopyrazinoquinazolinones was developed following the discovery of a domino quinazolinone rearrangement-intramolecular cyclization of N-H benzamidines. A Ugi-Mumm-Staudinger sequence employing an optically pure proline derivative gave quinazolinones that, upon N-Boc deprotection, rearranged to tautomeric Z-benzamidines. Subsequent spontaneous cyclization afforded 15 diastereomeric pyrazinoquinazolinone pairs in up to 83% overall yield and 89:11 d.r which were separated easily via routine chromatographic purification-the only one required in the entire process.

Abstract
Objective Peptidyl alkaloids, a series of important natural products can be assembled by fungal non-ribosomal peptide synthetases (NRPSs). However, many of the NRPSs associated gene clusters are silent under laboratory conditions, and the traditional chemical separation yields are low. In this study, we aim to discovery and efficiently prepare fungal peptidyl alkaloids assembled by fungal NRPSs. Methods Bioinformatics analysis of gene cluster containing NRPSs from the genome of Penicillium thymicola, and heterologous expression of the putative gene cluster in Aspergillus nidulans were performed. Isolation, structural identification, and biological evaluation of the product from heterologous expression were carried out. Results The putative tri-modular NRPS AncA was heterologous-expressed in A. nidulans to give anacine (1) with high yield, which showed moderate and selective cytotoxic activity against A549 cell line. Conclusion Heterologous expression in A. nidulans is an efficient strategy for mining fungal peptidyl alkaloids.

Abstract
Prenylated natural products have interesting pharmacological properties and prenylation reactions play crucial roles in controlling the activities of biomolecules. They are difficult to synthesize chemically, but enzymatic synthesis production is a desirable pathway. Cyclic dipeptide prenyltransferase catalyzes the regioselective Friedel-Crafts alkylation of tryptophan-containing cyclic dipeptides. This class of enzymes, which belongs to the dimethylallyl tryptophan synthase superfamily, is known to be flexible to aromatic prenyl receptors, while mostly retaining its typical regioselectivity. In this study, seven tryptophan-containing cyclic dipeptides 1a-7a were converted to their C7-regularly prenylated derivatives 1b-7b in the presence of dimethylallyl diphosphate (DMAPP) by using the purified 7-dimethylallyl tryptophan synthase (7-DMATS) as catalyst. The HPLC analysis of the incubation mixture and the NMR analysis of the separated products showed that the stereochemical structure of the substrate had a great influence on their acceptance by 7-DMATS. Determination of the kinetic parameters proved that cyclo-l-Trp-Gly (1a) consisting of a tryptophanyl and glycine was accepted as the best substrate with a KM value of 169.7 μM and a turnover number of 0.1307 s-1. Furthermore, docking studies simulated the prenyl transfer reaction of 7-DMATS and it could be concluded that the highest affinity between 7-DMATS and 1a. Preliminary results have been clearly shown that prenylation at C7 led to a significant increase of the anticancer and antimicrobial activities of the prenylated derivatives 1b-7b in all the activity test experiment, especially the prenylated product 4b.

Abstract
Aromatic prenyltransferases (PTases), including ABBA-type and dimethylallyl tryptophan synthase (DMATS)-type enzymes from bacteria and fungi, play important role for diversification of the natural products and improvement of the biological activities. For a decade, the characterization of enzymes and enzymatic synthesis of prenylated compounds by using ABBA-type and DMATS-type PTases have been demonstrated. Here, I introduce several examples of the studies on chemoenzymatic synthesis of unnatural prenylated compounds and the enzyme engineering of ABBA-type and DMATS-type PTases.

Abstract
Fungi are notoriously prolific producers of secondary metabolites including nonribosomal peptides (NRPs). The structural complexity of NRPs grants them interesting activities such as antibiotic, anti-cancer, and anti-inflammatory properties. The discovery of these compounds with attractive activities can be achieved by using two approaches: either by screening samples originating from various environments for their biological activities, or by identifying the related clusters in genomic sequences thanks to bioinformatics tools. This genome mining approach has grown tremendously due to recent advances in genome sequencing, which have provided an incredible amount of genomic data from hundreds of microbial species. Regarding fungal organisms, the genomic data have revealed the presence of an unexpected number of putative NRP-related gene clusters. This highlights fungi as a goldmine for the discovery of putative novel bioactive compounds. Recent development of NRP dedicated bioinformatics tools have increased the capacity to identify these gene clusters and to deduce NRPs structures, speeding-up the screening process for novel metabolites discovery. Unfortunately, the newly identified compound is frequently not or poorly produced by native producers due to a lack of expression of the related genes cluster. A frequently employed strategy to increase production rates consists in transferring the related biosynthetic pathway in heterologous hosts. This review aims to provide a comprehensive overview about the topic of NRPs discovery, from gene cluster identification by genome mining to the heterologous production in fungal hosts. The main computational tools and methods for genome mining are herein presented with an emphasis on the particularities of the fungal systems. The different steps of the reconstitution of NRP biosynthetic pathway in heterologous fungal cell factories will be discussed, as well as the key factors to consider for maximizing productivity. Several examples will be developed to illustrate the potential of heterologous production to both discover uncharacterized novel compounds predicted in silico by genome mining, and to enhance the productivity of interesting bio-active natural products.

Abstract
The ever-increasing bacterial genomic repositories reveal a great number of uncharacterized biosynthetic gene clusters, representing a tremendous resource for natural product discovery. Genome mining of the marine Streptomyces sp. NA03103 indicates the presence of an orphan nonribosomal peptide synthetase (NRPS) gene cluster (asm), to which there are no homologous gene clusters in the public genome databases. Heterologous expression of the asm gene cluster in the S. lividans SBT18 strain led to the discovery of two novel cyclopeptides, ashimides A and B (1 and 2), with 2 showing cytotoxic activity. In addition, we use bioinformatic analysis, gene inactivation and stable isotope labelling experiments, as well as in vitro biochemical assays, to present a coherent and novel assembly line for ashimide biosynthesis, featuring an unusual desaturation, halogenation and cyclization cascade catalyzed by a P450 monooxygenase and a FAD-dependent halogenase.

Appl Microbiol Biotechnol 2019; 103:3773-3781. [PMID: 30863875 DOI: 10.1007/s00253-019-09723-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2018] [Revised: 02/07/2019] [Accepted: 02/24/2019] [Indexed: 11/29/2022]
Abstract
In nature, cyclic dipeptide prenyltransferases catalyze regioselective Friedel-Crafts alkylations of tryptophan-containing cyclic dipeptides. This enzyme class, belonging to the dimethylallyl tryptophan synthase superfamily, is known to be flexible toward aromatic prenyl acceptors, while mostly retaining its typical regioselectivity. Ardeemin fumiquinazoline (FQ) (1), a tryptophan-containing cyclic tripeptide derivative, is assembled in Aspergillus fischeri by the non-ribosomal peptide synthetase ArdA and modified by the prenyltransferase ArdB, leading to the pharmaceutically active hexacyclic ardeemin. Therefore, 1 and its enantiomer ent-ardeemin FQ (2) constitute potential substrates for aromatic prenyltransferases. In this study, we investigated the acceptance of both enantiomers by two cyclic dipeptide C2-prenyltransferases BrePT and FtmPT1 and three C3-prenyltransferases CdpNPT, CdpC3PT, and AnaPT. LC-MS analysis of the incubation mixtures and NMR analysis of the isolated products revealed that the stereochemistry at C11 and C14 in 1 and 2 has a strong influence on their acceptance by these enzymes and the regioselectivity of the prenylation reactions. 1 was very well accepted by BrePT, FtmPT1, and CdpNPT, with C2- or C3-prenylated derivatives as predominant products, which fills the prenylation gaps by tryptophan prenyltransferases reported in a previous study. 2 was a poor substrate for all the enzymes and converted with low regioselectivity and mainly prenylated at C6 and C7 of the indole moiety.

Abstract
Non-ribosomal peptide synthetases (NRPSs) are key enzymes in microorganisms for the assembly of peptide backbones of biologically and pharmacologically active natural products. The monomodular NRPS-like enzymes comprise often an adenylation (A), a thiolation (T), and a thioesterase (TE) domain. In contrast to the NRPSs, they do not contain any condensation domain and usually catalyze a dimerization of α-keto carboxylic acids and thereby provide diverse scaffolds for further modifications. In this study, we established an expression system for NRPS-like genes in Saccharomyces cerevisiae. By expression of four known genes from Aspergillus terreus, their predicted function was confirmed and product yields of up to 35 mg per liter culture were achieved. Furthermore, expression of ATEG_03090 from the same fungus, encoding for the last uncharacterized NRPS-like enzyme with an A-T-TE domain structure, led to the formation of the benzoquinone derivative atromentin. All the accumulated products were isolated and their structures were elucidated by NMR and MS analyses. This study provides a convenient system for proof of gene function as well as a basis for synthetic biology, since additional genes encoding modification enzymes can be introduced.

Abstract
On the basis of the biosynthesis of alkaloids derived from tryptophan and considering the wide use of spirooxindole in drug molecular design, a series of novel spirooxindole derivatives containing an acylhydrazone moiety were designed, synthesized, and first evaluated for their biological activities. The results of bioassays indicated that the target compounds possessed good activities against tobacco mosaic virus (TMV); especially compound 4, containing a tert-butyl at the benzene ring, exhibited the best antiviral activity in vitro and inactivation, curative, and protection activities in vivo (48.4%, 58 ± 0.4, 55.2 ± 2.3, and 49.7 ± 1.1% at 500 μg/mL, respectively) compared with ribavirin (38.2, 36.4 ± 0.2, 37.5 ± 0.2, and 36.4 ± 0.1% at 500 μg/mL, respectively) and harmine (44.6, 40.5 ± 0.2, 38.6 ± 0.8, and 42.4 ± 0.6% at 500 μg/mL, respectively). At the same time, these compounds exhibited fungicidal activity selectively against certain fungi; most of these derivatives exhibited >60% fungicidal activity against Physalospora piricola at 50 mg/kg. Additionally, compounds 25 and 14 displayed excellent insecticidal activities (60% motality against C. pipiens pallens at 0.25 mg/kg) even at very low concentrations.

Abstract
The fungal indole prenyltransferase FtmPT1 is involved in the biosynthesis of fumitremorgins and catalyzes, in the presence of dimethylallyl diphosphate, a predominant regular prenylation of cyclo-L-Trp-L-Pro (brevianamide F) at position C-2 of the indole nucleus. Analysis of the substrate-bound structure of FtmPT1 revealed that brevianamide F forms a hydrogen bond via its carbonyl oxygen in the diketopiperazine moiety with the hydroxyl group of Tyr205 near the center of the prenyltransferase (PT) barrel. In this study, Tyr205 was mutated to 19 other proteinogenic amino acids by one-step site-directed mutagenesis. The obtained mutants were assayed in the presence of dimethylallyl diphosphate with brevianamide F. The enzyme products were isolated on HPLC and their structures were elucidated by NMR and MS analyses. Mutation of Tyr205 to Phe or Met did not change the behavior of FtmPT1 significantly, with regularly C2-prenylated brevianamide F as the predominant product. Interestingly, 15 of the obtained mutants also produced regularly C3-prenylated brevianamide F, with relative yields between 33 and 110 % of those of the regularly C2-prenylated derivatives. Among them, Y205C, Y205L, Y205N, Y205I, and Y205S showed similar brevianamide F consumption. Y205H, Y205Q, Y205V, Y205G, and Y205E showed activities between 47 and 77 % of that of the wild type. These results provide a solid basis for the construction of a brevianamide F regular C3-prenyltransferase by site-directed mutagenesis. Assaying stereoisomers of brevianamide F, cyclo-D-Trp-D-Pro, cyclo-L-Trp-D-Pro, and cyclo-D-Trp-L-Pro, with two selected mutants Y205N and Y205L resulted in the formation of reversely C3-prenylated derivatives as predominant products, being in sharp contrast to their regularly C2- and C3-prenylated derivatives with cyclo-L-Trp-L-Pro.

Abstract
Filamentous fungi are historically known as rich sources for production of biologically active natural products, so-called secondary metabolites. One particularly pharmaceutically relevant chemical group of secondary metabolites is the nonribosomal peptides synthesized by nonribosomal peptide synthetases (NRPSs). As most of the fungal NRPS gene clusters leading to production of the desired molecules are not expressed under laboratory conditions, efforts to overcome this impediment are crucial to unlock the full chemical potential of each fungal species. One way to activate these silent clusters is by overexpressing and deleting global regulators of secondary metabolism. The conserved fungal-specific regulator of secondary metabolism, LaeA, was shown to be a valuable target for sleuthing of novel gene clusters and metabolites. Additionally, modulation of chromatin structures by either chemical or genetic manipulation has been shown to activate cryptic metabolites. Furthermore, NRPS-derived molecules seem to be affected by cross talk between the specific gene clusters and some of these metabolites have a tissue- or developmental-specific regulation. This chapter summarizes how this knowledge of different tiers of regulation can be combined to increase production of NRPS-derived metabolites in fungal species.

Abstract
The emergence of next-generation sequencing has provided new opportunities in the discovery of new nonribosomal peptides (NRPs) and NRP synthethases (NRPSs). However, there remain challenges for the characterization of these megasynthases. While genetic methods in native hosts are critical in elucidation of the function of fungal NRPS, in vitro assays of intact heterologously expressed proteins provide deeper mechanistic insights in NRPS enzymology. Our previous work in the study of NRPS takes advantage of Saccharomyces cerevisiae strain BJ5464-npgA as a robust and versatile platform for characterization of fungal NRPSs. Here we describe the use of yeast recombination strategies in S. cerevisiae for cloning of the NRPS coding sequence in 2μ-based expression vector; the use of affinity chromatography for purification of NRPS from the total S. cerevisiae soluble protein fraction; and strategies for reconstitution of NRPSs activities in vitro.

Abstract
Flavin-dependent halogenases are potentially valuable biocatalysts for the regioselective halogenation of aromatic compounds. These enzymes, utilising benign inorganic halides, offer potential advantages over traditional non-enzymatic halogenation chemistry that often lacks regiocontrol and requires deleterious reagents. Here we extend the biocatalytic repertoire of the tryptophan halogenases, demonstrating how these enzymes can halogenate a range of alternative aryl substrates. Using structure guided mutagenesis we also show that it is possible to alter the regioselectivity as well as increase the activity of the halogenases with non-native substrates including anthranilic acid; an important intermediate in the synthesis and biosynthesis of pharmaceuticals and other valuable products.

Abstract
Genomics has revolutionized the research on fungal secondary metabolite (SM) biosynthesis. To elucidate the molecular and enzymatic mechanisms underlying the biosynthesis of a specific SM compound, the important first step is often to find the genes that responsible for its synthesis. The accessibility to fungal genome sequences allows the bypass of the cumbersome traditional library construction and screening approach. The advance in next-generation sequencing (NGS) technologies have further improved the speed and reduced the cost of microbial genome sequencing in the past few years, which has accelerated the research in this field. Here, we will present an example work flow for identifying the gene cluster encoding the biosynthesis of SMs of interest using an NGS approach. We will also review the different strategies that can be employed to pinpoint the targeted gene clusters rapidly by giving several examples stemming from our work.

Abstract
This review provides a summary of recent research advances in elucidating the biosynthesis of fungal indole alkaloids. The different strategies used to incorporate and derivatize the indole/indoline moieties in various families of fungal indole alkaloids will be discussed, including tryptophan-containing nonribosomal peptides, polyketide-nonribosomal peptide hybrids, and alkaloids derived from other indole building blocks. This review also includes a discussion regarding the downstream modifications that generate chemical and structural diversity among indole alkaloids.

Abstract
The polycycles merochlorin A and B are complex halogenated meroterpenoid natural products with significant antibacterial activities and are produced by the marine bacterium Streptomyces sp. strain CNH-189. Heterologously produced enzymes and chemical synthesis are employed herein to fully reconstitute the merochlorin biosynthesis in vitro. The interplay of a dedicated type III polyketide synthase, a prenyl diphosphate synthase, and an aromatic prenyltransferase allow formation of a highly unusual aromatic polyketide-terpene hybrid intermediate which features an unprecedented branched sesquiterpene moiety from isosesquilavandulyl diphosphate. As supported by in vivo experiments, this precursor is furthermore chlorinated and cyclized to merochlorin A and isomeric merochlorin B by a single vanadium-dependent haloperoxidase, thus completing the remarkably efficient pathway.

ACTA ACUST UNITED AC 2014; 20:870-8.

Abstract
The bimodular 276 kDa nonribosomal peptide synthetase AspA from Aspergillus alliaceus, heterologously expressed in Saccharomyces cerevisiae, converts tryptophan and two molecules of the aromatic β-amino acid anthranilate (Ant) into a pair of tetracyclic peptidyl alkaloids asperlicin C and D in a ratio of 10:1. The first module of AspA activates and processes two molecules of Ant iteratively to generate a tethered Ant-Ant-Trp-S-enzyme intermediate on module two. Release is postulated to involve tandem cyclizations, in which the first step is the macrocyclization of the linear tripeptidyl-S-enzyme, by the terminal condensation (CT) domain to generate the regioisomeric tetracyclic asperlicin scaffolds. Computational analysis of the transannular cyclization of the 11-membered macrocyclic intermediate shows that asperlicin C is the kinetically favored product due to the high stability of a conformation resembling the transition state for cyclization, while asperlicin D is thermodynamically more stable.

Abstract
Complexity generation in naturally occurring peptide scaffolds can occur either by posttranslational modifications of nascent ribosomal proteins or through post assembly line tailoring of nonribosomal peptides. Short enzymatic pathways utilizing bimodular and trimodular nonribosomal peptide synthetase (NRPS) assembly lines, followed by tailoring oxygenases and/or prenyltransferases, efficiently construct complex fungal peptidyl alkaloid scaffolds in Aspergilli, Neosartorya, and Penicillium species. Use of the nonproteinogenic amino acid anthranilate as chain-initiating building block and chain-terminating intramolecular nucleophile leads efficiently to peptidyl alkaloid scaffolds with two to seven fused rings.
