Abstract
Tuberculosis (TB), an airborne infectious disease caused by Mycobacterium tuberculosis, has become the leading cause of death. The subsequent emergence of multidrug-resistant, extensively drug-resistant and totally drug-resistant strains, brings an urgent need to discover novel anti-TB drugs. Among them, microbial-derived anti-mycobacterial peptides, including ribosomally synthesized and post-translationally modified peptides (RiPPs) and multimodular nonribosomal peptides (NRPs), now arise as promising candidates for TB treatment. This review presents 96 natural RiPP and NRP families from bacteria and fungi that have broad spectrum in vitro activities against non-resistant and drug-resistant mycobacteria. In addition, intracellular targets of 22 molecules are the subject of much attention. Meanwhile, chemical features of 38 families could be modified in order to improve properties. In final, structure-activity relationships suggest that the modifications of various groups, especially the peptide side chains, the amino acid moieties, the cyclic peptide skeletons, various special groups, stereochemistry and entire peptide chain length are important for increasing the potency.

Abstract
A mild and chemoselective method for the thioacylation of amines, including amino acids and peptides, using gem-difluoroalkenes and sulfide, is reported. The distinguishing of the different nucleophilic sites (S-site and diverse N-sites) by the chemoselective C-F bond functionalization of gem-difluoroalkenes enables the unique synergistic defluorinative coupling reaction. This reaction features mild conditions, is operationally simple, efficient, and gram-scalable, tolerates various functional groups, and is activator-free and without racemization. Thioamide moieties were incorporated site-specifically into bioactive compounds. The proposed mechanism is illustrated by a DFT calculation.

Abstract
The increase in global travel and the incorrect and excessive use of antibiotics has led to an unprecedented rise in antibiotic resistance in bacterial and fungal populations. To overcome these problems, novel bioactive natural products must be discovered, which may be found in underexplored environments, such as estuarine habitats. In the present work, estuarine actinomycetotal strains were isolated with conventional and iChip techniques from the Tagus estuary in Alcochete, Portugal, and analysed for different antimicrobial bioactivities. Extracts were produced from the isolated cultures and tested for bioactivity against Staphylococcus aureus ATCC 29213, Escherichia coli ATCC 25922, Aspergillus fumigatus ATCC 240305, Candida albicans ATCC 10231 and Trichophyton rubrum FF5. Furthermore, bioactive extracts were subjected to dereplication by high-performance liquid chromatography (HPLC) and high-resolution mass spectrometry (HRMS) to putatively identify their chemical components. In total, 105 isolates belonging to 3 genera were obtained. One which was isolated, MTZ3.1 T, represents a described novel taxon for which the name Streptomyces meridianus was proposed. Regarding the bioactivity testing, extracts from 12 strains proved to be active against S. aureus, 2 against E. coli, 4 against A. fumigatus, 3 against C. albicans and 10 against T. rubrum. Dereplication of bioactive extracts showed the presence of 28 known bioactive molecules, 35 hits have one or more possible matches in the DNP and 18 undescribed ones. These results showed that the isolated bacteria might be the source of new bioactive natural products.

Association of Radical Chemistry with LanD Flavoprotein Activity for C-Terminal Macrocyclization of a Ribosomal Peptide by Formation of an Unsaturated Thioether Residue. Angew Chem Int Ed Engl 2023; 62:e202308733. [PMID: 37431841 DOI: 10.1002/anie.202308733] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 07/10/2023] [Accepted: 07/11/2023] [Indexed: 07/12/2023]
Abstract
LanD flavoproteins catalyze oxidative decarboxylation of the C-terminal Cys residue of a peptide to produce an enethiol. This enethiol is highly reactive and can be coupled with an upstream dehydroamino acid through Michael addition to form S-[2-aminovinyl](3-methyl)cysteine, an unsaturated thioether residue known to be characteristic of an array of C-terminally macrocyclized, ribosomally synthesized and posttranslationally modified peptides (RiPPs). Based on a two-stage bioinformatics mining of posttranslational modifications (PTMs) related to C-terminal Cys processing, we report herein that LanD activity can couple with radical S-adenosylmethionine chemistry to provide a new unsaturated thioether residue, S-[2-aminovinyl]-3-carbamoylcysteine, by conjugating the resultant enethiol with Cβ of the Asn residue in the C-terminal NxxC motif of a peptide for macrocyclization. This study furthers our understanding of the variety of PTMs involved in creating the structure diversity of macrocyclic RiPPs.

Abstract
Derivatizing natural products (NPs) is essential in structure-activity relationship (SAR) studies, compound optimization, and drug development. Ribosomally synthesized and post-translationally modified peptides (RiPPs) represent one of the major classes of natural products. Thioholgamide represents thioamitide - a recently emerged family of RiPPs with unique structures and great potential in anticancer drug development. Although the method for generating the RiPP library by codon substitutions in the precursor peptide gene is straightforward, the techniques to perform RiPP derivatization in Actinobacteria remain limited and time-consuming. Here, we report a facile system for producing a library of randomized thioholgamide derivatives utilizing an optimized Streptomyces host. This technique enabled us to access all possible amino acid substitutions of the thioholgamide molecule, one position at a time. Out of 152 potential derivatives, 85 were successfully detected, revealing the impact of amino acid substitutions on thioholgamide post-translational modifications (PTMs). Moreover, new PTMs were observed among thioholgamide derivatives: thiazoline heterocycles, which have not yet been reported for thioamitides, and S-methylmethionine, which is very rare in nature. The obtained library was subsequently used for thioholgamide SAR studies and stability assays.

Abstract
Thioamide peptides were synthesized in a straightforward one-pot process via the linkage of diverse natural amino acids in the presence of thiolphosphonate and trichlorosilane, wherein carbonyl groups were replaced with thiono compounds with minimal racemization. Experimental and computational mechanistic studies demonstrated that the trichlorosilane enables the activation of carboxylic acids via intense interactions with the Si-O bond, followed by coupling of the carboxylic acids with thiolphosphonate to obtain the key intermediate S-acyl dithiophosphate. Silyl-activated quadrangular metathesis transition states afforded the thioamide peptides. The potential applications of these thioamide peptides were further highlighted via late-stage linkages of diverse natural products and pharmaceutical drugs and the thioamide moiety.

Abstract
Ribosomally synthesized and post-translationally modified peptides (RiPPs) are of increasing interest in natural products as well as drug discovery. This empowers not only the unique chemical structures and topologies in natural products but also the excellent bioactivities such as antibacteria, antifungi, antiviruses, and so on. Advances in genomics, bioinformatics, and chemical analytics have promoted the exponential increase of RiPPs as well as the evaluation of biological activities thereof. Furthermore, benefiting from their relatively simple and conserved biosynthetic logic, RiPPs are prone to be engineered to obtain diverse analogues that exhibit distinct physiological activities and are difficult to synthesize. This Review aims to systematically address the variety of biological activities and/or the mode of mechanisms of novel RiPPs discovered in the past decade, albeit the characteristics of selective structures and biosynthetic mechanisms are briefly covered as well. Almost one-half of the cases are involved in anti-Gram-positive bacteria. Meanwhile, an increasing number of RiPPs related to anti-Gram-negative bacteria, antitumor, antivirus, etc., are also discussed in detail. Last but not least, we sum up some disciplines of the RiPPs' biological activities to guide genome mining as well as drug discovery and optimization in the future.

Thioalbamide inhibits F oF 1-ATPase in breast cancer cells and reduces tumor proliferation and invasiveness in breast cancer in vivo models. Mol Metab 2023; 68:101674. [PMID: 36657563 PMCID: PMC9883262 DOI: 10.1016/j.molmet.2023.101674] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Revised: 12/07/2022] [Accepted: 01/11/2023] [Indexed: 01/18/2023] Open
Abstract
OBJECTIVE Thioalbamide is a ribosomally synthesized and post-translationally modified peptide (RiPP) belonging to the family of thioamitides, a rare class of microbial specialized metabolites with unusual post-translational modifications and promising biological activities. Recent studies have demonstrated the ability of thioalbamide to exert highly selective cytotoxic effects on tumor cells by affecting their energy metabolism, thus causing abnormal ROS production and triggering apoptosis. This study is aimed to investigate the molecular mechanisms underlying the antitumor activity of thioalbamide in order to identify its exact molecular target. METHODS Wild type MCF-7 and MDA-MB-231 breast cancer cell lines as well as cancer cells deprived of mitochondrial DNA (ρ0 cells) were employed in order to assess thioalbamide effects on tumor bioenergetics. In this regard, metabolic profile was evaluated by a Seahorse XFe96 analyzer, and the activity of the enzyme complexes involved in oxidative phosphorylation was quantified by spectrophotometric assays. Thioalbamide effects on tumor invasiveness were assessed by gelatin zymography experiments and invasion assays. In vivo experiments were carried out on breast cancer xenograft and "experimental metastasis" mouse models. RESULTS Experiments carried out on ρ0 breast cancer cells, together with Seahorse analysis and the application of spectrophotometric enzymatic assays, highlighted the ability of thioalbamide to affect the mitochondrial respiration process, and allowed to propose the FoF1-ATPase complex as its main molecular target in breast cancer cells. Additionally, thioalbamide-mediated OXPHOS inhibition was shown, for the first time, to reduce tumor invasiveness by inhibiting metalloproteinase-9 secretion. Furthermore, this study has confirmed the antitumor potential of thioalbamide in two different in vivo models. In particular, experiments on MCF-7 and MDA-MB-231 xenograft mouse models have confirmed in vivo its high anti-proliferative and pro-apoptotic activity, while experiments on MDA-MB-231 ″experimental metastasis" mouse models have highlighted its ability to inhibit breast cancer cell invasiveness. CONCLUSIONS Overall, our results shed more light on the molecular mechanisms underlying the pharmacological potential of thioamidated peptides, thus reducing the gap that separates this rare class of microbial metabolites from clinical studies, which could validate them as effective tools for cancer treatment.

Abstract
YcaO enzymes catalyze ATP-dependent post-translation modifications on peptides, including the installation of (ox/thi)azoline, thioamide and/or amidine moieties. Here we demonstrate that, in the biosynthesis of the bis-methyloxazolic alkaloid muscoride A, the YcaO enzyme MusD carries out both ATP-dependent cyclodehydration and peptide bond cleavage, which is a mechanism unprecedented for such a reaction. YcaO-catalyzed modifications are proposed to occur through a backbone O-phosphorylated intermediate, but this mechanism remains speculative. We report, to our knowedge, the first characterization of an acyl-phosphate species consistent with the proposed mechanism for backbone amide activation. The 3.1-Å-resolution cryogenic electron microscopy structure of MusD along with biochemical analysis allow identification of residues that enable peptide cleavage reaction. Bioinformatics analysis identifies other cyanobactin pathways that may deploy bifunctional YcaO enzymes. Our structural, mutational and mechanistic studies expand the scope of modifications catalyzed by YcaO proteins to include peptide hydrolysis and provide evidence for a unifying mechanism for the catalytically diverse outcomes.

Abstract
The formation of (2S,3S)-S-[(Z)-aminovinyl]-3-methyl-D-cysteine (AviMeCys) substructures was developed based on the photocatalyzed-oxidative decarboxylation of lanthionine-bearing peptides. The decarboxylative selenoetherification of the N-hydroxyphthalimide ester, generated in situ, proceeded under mild conditions at −40 °C in the presence of 1 mol% of eosin Y-Na2 as a photocatalyst and the Hantzsch ester. The following β-elimination of the corresponding N,Se-acetal was operated in a one-pot operation, led to AviMeCys substructures found in natural products in moderate to good yields. The sulfide-bridged motif, and also the carbamate-type protecting groups, such as Cbz, Teoc, Boc and Fmoc groups, were tolerant under the reaction conditions.

Abstract
Linaridins and lanthipeptides are two classes of natural products belonging to the ribosomally synthesized and posttranslationally modified peptide (RiPP) superfamily. Although these two RiPP classes share similar structural motifs such as dehydroamino acids and thioether-based cross-links, the biosynthesis of linaridins and lanthipeptides involved distinct sets of enzymes. Here, we report the identification of a novel lanthipeptide cypepeptin from a recombinant strain of Streptomyces lividans, which harbors most of the cypemycin (a prototypic linaridin) biosynthetic gene cluster but lacks the decarboxylase gene cypD. In contrast to the generally believed structure of cypemycin, multiple d-amino acids and Z-dehydrobutyrines were observed in both cypepeptin and cypemycin, and the stereochemistry of each amino acid was established by the extensive structural analysis in combination with genetic knockout and mutagenesis studies. Comparative analysis of cypemycin and cypepeptin showed that the aminovinyl-cysteine (AviCys) moiety of cypemycin plays an essential role in disrupting the cell integrity of M. luteus, which cannot be functionally substituted by the structurally similar lanthionine moiety.

Abstract
Ribosomally synthesized and post-translationally modified peptides (RiPPs) are a natural product class that has undergone significant expansion due to the rapid growth in genome sequencing data and recognition that they are made by biosynthetic pathways that share many characteristic features. Their mode of actions cover a wide range of biological processes and include binding to membranes, receptors, enzymes, lipids, RNA, and metals as well as use as cofactors and signaling molecules. This review covers the currently known modes of action (MOA) of RiPPs. In turn, the mechanisms by which these molecules interact with their natural targets provide a rich set of molecular paradigms that can be used for the design or evolution of new or improved activities given the relative ease of engineering RiPPs. In this review, coverage is limited to RiPPs originating from bacteria.

Abstract
The cis-trans isomerization of (thio)amides was studied by DFT calculations to get the model for the higher preference for the cis conformation by guided predictive chemistry, suggesting how to select the alkyl/aryl substituents on the C/N atoms that lead to the trans isomer. Multilinear analysis, together with cross-validation analysis, helped to select the best fitting parameters to achieve the energy barriers of the cis to trans interconversion, as well as the relative stability between both isomers. Double experimental check led to the synthesis of the best trans candidate with sterically demanding t-butyl substituents, confirming the utility of predictive chemistry, bridging organic and computational chemistry.

Abstract
The past decade has seen impressive advances in understanding the biosynthesis of ribosomally synthesized and posttranslationally modified peptides (RiPPs). One of the most common modifications found in these natural products is macrocyclization, a strategy also used by medicinal chemists to improve metabolic stability and target affinity and specificity. Another tool of the peptide chemist, modification of the amides in a peptide backbone, has also been observed in RiPPs. This review discusses the molecular mechanisms of biosynthesis of a subset of macrocyclic RiPP families, chosen because of the unusual biochemistry involved: the five classes of lanthipeptides (thioether cyclization by Michael-type addition), sactipeptides and ranthipeptides (thioether cyclization by radical chemistry), thiopeptides (cyclization by [4+2] cycloaddition), and streptide (cyclization by radical C-C bond formation). In addition, the mechanisms of backbone amide methylation, backbone epimerization, and backbone thioamide formation are discussed, as well as an unusual route to small molecules by posttranslational modification.

Abstract
Large-scale genome-mining analyses have identified an enormous number of cryptic biosynthetic gene clusters (BGCs) as a great source of novel bioactive natural products. Given the sheer number of natural product (NP) candidates, effective strategies and computational methods are keys to choosing appropriate BGCs for further NP characterization and production. This review discusses genomics-based approaches for prioritizing candidate BGCs extracted from large-scale genomic data, by highlighting studies that have successfully produced compounds with high chemical novelty, novel biosynthesis pathway, and potent bioactivities. We group these studies based on their BGC-prioritization logics: detecting presence of resistance genes, use of phylogenomics analysis as a guide, and targeting for specific chemical structures. We also briefly comment on the different bioinformatics tools used in the field and examine practical considerations when employing a large-scale genome mining study.

Abstract
Thioamides are 'single-atom' isosteres of amide bonds that have found broad applications in organic synthesis, biochemistry and drug discovery. In this New Talent themed issue, we present a general strategy for activation of N-C(S) thioamide bonds by ground-state-destabilization. This concept is outlined in the context of a full study on transamidation of thioamides with nucleophilic amines, and relies on (1) site-selective N-activation of the thioamide bond to decrease resonance and (2) highly chemoselective nucleophilic acyl addition to the thioamide CS bond. The follow-up collapse of the tetrahedral intermediate is favored by the electronic properties of the amine leaving group. The ground-state-destabilization concept of thioamides enables weakening of the N-C(S) bond and rationally modifies the properties of valuable thioamide isosteres for the development of new methods in organic synthesis. We fully expect that in analogy to the burgeoning field of destabilized amides introduced by our group in 2015, the thioamide bond ground-state-destabilization activation concept will find broad applications in various facets of chemical science, including metal-free, metal-catalyzed and metal-promoted reaction pathways.

Abstract
Thioholgamides are ribosomally synthesized and posttranslationally modified peptides (RiPPs), with potent activity against cancerous cell lines and an unprecedented structure. Despite being one of the most structurally and chemically complex RiPPs, very few biosynthetic steps have been elucidated. Here, we report the complete in vitro reconstitution of the biosynthetic pathway. We demonstrate that thioamidation is the first step and acts as a gatekeeper for downstream processing. Thr dehydration follows thioamidation, and our studies reveal that both these modifications require the formation of protein complexes─ThoH/I and ThoC/D. Harnessing the power of AlphaFold, we deduce that ThoD acts as a lyase and also proposes putative catalytic residues. ThoF catalyzes the oxidative decarboxylation of the terminal Cys, and the subsequent macrocyclization is facilitated by ThoE. This is followed by Ser dehydration, which is also carried out by ThoC/D. ThoG is responsible for histidine bis-N-methylation, which is a prerequisite for His β-hydroxylation─a modification carried out by ThoJ. The last step of the pathway is the removal of the leader peptide by ThoK to afford mature thioholgamide.

Abstract
Thioamitides are ribosomally synthesized and posttranslationally modified peptide (RiPP) natural products that hold great potential in anticancer drug development. Members in this RiPP family feature a thioamidated peptidyl chain conjugated with a macrocyclic ring system that contains two nonproteinogenic residues, 2-aminovinyl-cysteine (AviCys) and β-hydroxy-N,N-dimethyl-l-histidine (hdmHis). Focusing on the hdmHis residue that is unique to thioamitides, we report the enzymatic process for His functionalization and, more importantly, the timing of its related reactions with the other posttranslational modifications (PTMs) involved in thioamitide biosynthesis. His functionalization involves the activities of an S-adenosyl-l-methionine-dependent protein and a 2-oxoglutarate-Fe(II) monooxygenase for His bis-N-dimethylation and subsequent β-hydroxylation in a highly ordered manner. This process relies on the leader peptide sequence of the precursor peptide and on the establishment of the AviCys-containing, C-terminal macrocyclic ring system in particular. In contrast, prior peptide thioamidation is not required. Knowledge gained from the catalytic logic, specificity, and compatibility of His functionalization greatly furthers our understanding of the process through which nature develops thioamitides from a ribosomally synthesized peptide precursor.

Abstract
Thioamitides are apoptosis-inducing ribosomally synthesized and post-translationally modified peptides (RiPPs) with substantial post-translational modifications (PTMs), whose biosynthetic details remain elusive. We reconstituted their key PTMs through in vitro enzymatic reactions and gene coexpressions in E. coli and rigorously demonstrated the order of those modifications. Notably, thioamitide biosynthesis involves N- to C-terminal thioamidations and employs both leader-dependent and leader-independent reactions followed by leader removal by successive degradation. Our study provides a comprehensive overview of thioamitide biosynthesis and lays the foundation for thioamitide engineering in E. coli.

Abstract
Thioamitides are a group of ribosomally synthesized and post-translationally modified peptides that possess diverse bioactivities and are usually featured by thioamide and 2-aminovinyl-cysteine (AviCys) motifs. In natural product thiosparsoamide, the AviCys motif is formed by an enzyme cascade formed by the flavin-dependent decarboxylase SpaD and dehydratase SpaKC. SpaKC is a lanthipeptide synthetase homolog located outside the thiosparsoamide biosynthetic gene cluster. In this study, we show that SpaKC does not strictly require the N-terminal leader peptide of precursor peptide SpaA for substrate recognition and dehydration. The C-terminal seven residues serve as a minimal structural element for enzyme recognition. Through a systematic mutagenesis experiments, our study demonstrates the relaxed substrate specificity of SpaKC as a dehydratase and potentially as an enzymatic tool to install dehydroalanine or dehydrobutyrine motifs in peptides.

Abstract
A sulfur-involved ligation for thioamide quasi-peptides was developed via amino acids and amino aldehydes coupling. The key to the transformation was the chelation of copper with imines for chiral activation and fixation. In this environment, linear polysulfur decreased the alkalinity of single sulfur anions to prevent racemization caused by the interaction between sulfur and sodium sulfide. Dipeptides, tripeptides, tetrapeptides, and the linkage between the drug and amino acids were successfully obtained.

Abstract
Covering: 2016 to 2021With genetic information available for hundreds of thousands of organisms in publicly accessible databases, scientists have an unprecedented opportunity to meticulously survey the diversity and inner workings of life. The natural product research community has harnessed this breadth of sequence information to mine microbes, plants, and animals for biosynthetic enzymes capable of producing bioactive compounds. Several orthogonal genome mining strategies have been developed in recent years to target specific chemical features or biological properties of bioactive molecules using biosynthetic, resistance, or transporter proteins. These "biosynthetic hooks" allow researchers to query for biosynthetic gene clusters with a high probability of encoding previously undiscovered, bioactive compounds. This review highlights recent case studies that feature orthogonal approaches that exploit genomic information to specifically discover bioactive natural products and their gene clusters.

Abstract
Thioamides are found in a few natural products and two known protein assemblies: the Escherichia coli ribosome and methyl-coenzyme M reductase (MCR) from methane-metabolizing archaea. Compared to an amide, thioamides alter the physical and chemical properties of peptide backbones, including the conformation dynamics, proteolytic stability, hydrogen-bonding capabilities, and possibly reactivity of a protein when installed. Recently, there has been significant progress in elucidating enzymatic post-translational thioamide installation, with most work leveraging the archaeal MCR-modifying enzymes. This chapter describes the protocols used for the in vitro enzymatic thioamidation of MCR-derived peptides, including polypeptide overexpression, purification, reaction reconstitution, and mass spectrometry-based product analysis. In addition, we highlight the protocols used for the biochemical, kinetics, and binding studies using recombinant enzymes obtained heterologously from E. coli. We anticipate that these methods will serve to guide future studies on peptide post-translational thioamidation, as well as other peptide backbone modifications using a parallel workflow.

Abstract
YcaO enzymes catalyze several post-translational modifications on peptide substrates, including thioamidation, which substitutes an amide oxygen with sulfur. Most predicted thioamide-forming YcaO enzymes are encoded adjacent to TfuA, which when present, is required for thioamidation. While activation of the peptide amide backbone is well established for YcaO enzymes, the function of TfuA has remained enigmatic. Here we characterize the TfuA protein involved in methyl-coenzyme M reductase thioamidation and demonstrate that TfuA catalyzes the hydrolysis of thiocarboxylated ThiS (ThiS-COSH), a proteinaceous sulfur donor, and enhances the affinity of YcaO toward the thioamidation substrate. We also report a crystal structure of a TfuA, which displays a new protein fold. Our structural and mutational analyses of TfuA have uncovered conserved binding interfaces with YcaO and ThiS in addition to revealing a hydrolase-like active site featuring a Ser-Lys catalytic pair.

Abstract
Thioamidated ribosomally synthesized and post-translationally modified peptides (RiPPs) are recently characterized natural products with wide range of potent bioactivities, such as antibiotic, antiproliferative, and cytotoxic activities. These peptides are distinguished by the presence of thioamide bonds in the peptide backbone catalyzed by the YcaO-TfuA protein pair with its genes adjacent to each other. Genome mining has facilitated an in silico approach to identify biosynthesis gene clusters (BGCs) responsible for thioamidated RiPP production. In this work, publicly available genomic data was used to detect and illustrate the diversity of putative BGCs encoding for thioamidated RiPPs. AntiSMASH and RiPPER analysis identified 613 unique TfuA-related gene cluster families (GCFs) and 797 precursor peptide families, even on phyla where the presence of these clusters have not been previously described. Several additional biosynthesis genes are colocalized with the detected BGCs, suggesting an array of possible chemical modifications. This study shows that thioamidated RiPPs occupy a widely unexplored chemical landscape.

Abstract
Thiostreptamide S4 is a thioamitide, a family of promising antitumour ribosomally synthesised and post-translationally modified peptides (RiPPs). The thioamitides are one of the most structurally complex RiPP families, yet very few thioamitide biosynthetic steps have been elucidated, even though the biosynthetic gene clusters (BGCs) of multiple thioamitides have been identified. We hypothesised that engineering the thiostreptamide S4 BGC in a heterologous host could provide insights into its biosynthesis when coupled with untargeted metabolomics and targeted mutations of the precursor peptide. Modified BGCs were constructed, and in-depth metabolomics enabled a detailed understanding of the biosynthetic pathway to thiostreptamide S4, including the identification of a protein critical for amino acid dehydration that has homology to HopA1, an effector protein used by a plant pathogen to aid infection. We use this biosynthetic understanding to bioinformatically identify diverse RiPP-like BGCs, paving the way for future RiPP discovery and engineering.

Abstract
2-Aminovinyl-cysteine (AviCys) is a thioether amino acid shared by a variety of ribosomally synthesized and posttranslationally modified peptides (RiPPs). Based on investigations into the biosynthesis of thioviridamide RiPPs in Streptomyces sp. NRRL S-87, we here report a path for the formation of this unusual thioether residue. This path relies on four dedicated proteins: phosphotransferase TvaCS-87, Lyase TvaDS-87, kinase homolog TvaES-87, and LanD-like flavoprotein TvaFS-87. TvaES-87 plays a critical role in effective AviCys formation. During the posttranslational modifications of the precursor peptide, it works with TvaFS-87 to form a minimum AviCys synthetase complex, which follows the combined activity of TvaCDS-87 for Thr dehydration and catalyzes Cys oxidative decarboxylation and subsequent Michael addition of the resulting enethiol nucleophile onto the newly formed dehydroamino acid residue for cyclization. With TvaES-87, TvaFS-87 activity for Cys processing can be coordinated with TvaCDS-87 activity for minimizing competitive or unexpected spontaneous reactions and forming AviCys effectively.

Abstract
Covering: up to June 2020Ribosomally-synthesized and post-translationally modified peptides (RiPPs) are a large group of natural products. A community-driven review in 2013 described the emerging commonalities in the biosynthesis of RiPPs and the opportunities they offered for bioengineering and genome mining. Since then, the field has seen tremendous advances in understanding of the mechanisms by which nature assembles these compounds, in engineering their biosynthetic machinery for a wide range of applications, and in the discovery of entirely new RiPP families using bioinformatic tools developed specifically for this compound class. The First International Conference on RiPPs was held in 2019, and the meeting participants assembled the current review describing new developments since 2013. The review discusses the new classes of RiPPs that have been discovered, the advances in our understanding of the installation of both primary and secondary post-translational modifications, and the mechanisms by which the enzymes recognize the leader peptides in their substrates. In addition, genome mining tools used for RiPP discovery are discussed as well as various strategies for RiPP engineering. An outlook section presents directions for future research.

Abstract
Thioviridamide-like compounds, including thioholgamides, are ribosomally synthesized and post-translationally modified peptide natural products with potent anticancer cell activity and an unprecedented structure. Very little is known about their biosynthesis, and we were intrigued by the β-hydroxy-N1, N3-dimethylhistidinium moiety found in these compounds. Here we report the construction of a heterologous host capable of producing thioholgamide with a 15-fold increased yield compared to the wild-type strain. A knockout of thoJ, encoding a predicted nonheme monooxygenase, shows that ThoJ is essential for thioholgamide β-hydroxylation. The crystal structure of ThoJ exhibits a typical mono/dioxygenase fold with conserved key active-site residues. Yet, ThoJ possesses a very large substrate binding pocket that appears suitable to receive a cyclic thioholgamide intermediate for hydroxylation. The improved production of the heterologous host will enable the dissection of the individual biosynthetic steps involved in biosynthesis of this exciting RiPP family.

Abstract
Natural products represent powerful tools searching for novel anticancer drugs. Thioholgamide A (thioA) is a ribosomally synthesized and post-translationally modified peptide, which has been identified as a product of Streptomyces sp. MUSC 136T. In this study, we provide a comprehensive biological profile of thioA, elucidating its effects on different hallmarks of cancer in tumor cells as well as in macrophages as crucial players of the tumor microenvironment. In 2D and 3D in vitro cell culture models thioA showed potent anti-proliferative activities in cancer cells at nanomolar concentrations. Anti-proliferative actions were confirmed in vivo in zebrafish embryos. Cytotoxicity was only induced at several-fold higher concentrations, as assessed by live-cell microscopy and biochemical analyses. ThioA exhibited a potent modulation of cell metabolism by inhibiting oxidative phosphorylation, as determined in a live-cell metabolic assay platform. The metabolic modulation caused a repolarization of in vitro differentiated and polarized tumor-promoting human monocyte-derived macrophages: ThioA-treated macrophages showed an altered morphology and a modulated expression of genes and surface markers. Taken together, the metabolic regulator thioA revealed low activities in non-tumorigenic cells and an interesting anti-cancer profile by orchestrating different hallmarks of cancer, both in tumor cells as well as in macrophages as part of the tumor microenvironment.

Abstract
As a result of the exponential increase in genomic data, discovery of novel ribosomally synthesized and post-translationally modified peptide natural products (RiPPs) has progressed rapidly in the past decade. The lanthipeptides are a major subset of RiPPs. Through genome mining we identified a novel lanthipeptide biosynthetic gene cluster (lah) from Lachnospiraceae bacterium C6A11, an anaerobic bacterium that is a member of the human microbiota and which is implicated in the development of host disease states such as type 2 diabetes and resistance to Clostridium difficile colonization. The lah cluster encodes at least seven putative precursor peptides and multiple post-translational modification (PTM) enzymes. Two unusual class II lanthipeptide synthetases LahM1/M2 and a substrate-tolerant S-adenosyl-l-methionine (SAM)-dependent methyltransferase LahSB are biochemically characterized in this study. We also present the crystal structure of LahSB in complex with product S-adenosylhomocysteine. This study sets the stage for further exploration of the final products of the lah pathway as well as their potential physiological functions in human/animal gut microbiota.

Uncovering the unexplored diversity of thioamidated ribosomal peptides in Actinobacteria using the RiPPER genome mining tool. Nucleic Acids Res 2019; 47:4624-4637.

Abstract
The rational discovery of new specialized metabolites by genome mining represents a very promising strategy in the quest for new bioactive molecules. Ribosomally synthesized and post-translationally modified peptides (RiPPs) are a major class of natural product that derive from genetically encoded precursor peptides. However, RiPP gene clusters are particularly refractory to reliable bioinformatic predictions due to the absence of a common biosynthetic feature across all pathways. Here, we describe RiPPER, a new tool for the family-independent identification of RiPP precursor peptides and apply this methodology to search for novel thioamidated RiPPs in Actinobacteria. Until now, thioamidation was believed to be a rare post-translational modification, which is catalyzed by a pair of proteins (YcaO and TfuA) in Archaea. In Actinobacteria, the thioviridamide-like molecules are a family of cytotoxic RiPPs that feature multiple thioamides, which are proposed to be introduced by YcaO-TfuA proteins. Using RiPPER, we show that previously undescribed RiPP gene clusters encoding YcaO and TfuA proteins are widespread in Actinobacteria and encode a highly diverse landscape of precursor peptides that are predicted to make thioamidated RiPPs. To illustrate this strategy, we describe the first rational discovery of a new structural class of thioamidated natural products, the thiovarsolins from Streptomyces varsoviensis.

Abstract
Thioalbamide, a thioamidated peptide biosynthesized by Amycolatopsis alba, is a thioviridamide-like molecule, and is part of a family of natural products representing a focus of biotechnological and pharmaceutical research in recent years due to their potent anti-proliferative and cytotoxic activities on malignant cells. Despite the high antitumor potential observed at nanomolar concentrations, the mechanisms underlying thioalbamide activity are still not known. In this work, the cellular effects induced by thioalbamide treatment on breast cancer cell lines were evaluated for the first time, highlighting the ability of this microbial natural peptide to induce mitochondrial dysfunction, oxidative stress, and apoptotic cell death. Furthermore, we demonstrate that thioalbamide can inhibit the propagation of cancer stem-like cells, which are strongly dependent on mitochondrial function and are responsible for chemotherapy resistance, metastasis, and tumor recurrence.

Abstract
Thioviridamide, prethioviridamide, and JBIR-140, which are ribosomally synthesized and post-translationally modified peptides (RiPPs) possessing five thioamide bonds, induce selective apoptosis in various cancer cells, especially those expressing the adenovirus oncogene E1A. However, the target protein of this unique family of bioactive compounds was previously unknown. To investigate the mechanism of action, we adopted a combined approach of genome-wide shRNA library screening, transcriptome profiling, and biochemical identification of prethioviridamide-binding proteins. An shRNA screen identified 63 genes involved in cell sensitivity to prethioviridamide, which included translation initiation factors, aminoacyl tRNA synthetases, and mitochondrial proteins. Transcriptome profiling and subsequent analysis revealed that prethioviridamide induces the integrated stress response (ISR) through the GCN2-ATF4 pathway, which is likely to cause cell death. Furthermore, we found that prethioviridamide binds and inhibits respiratory chain complex V (F1Fo-ATP synthase) in mitochondria, suggesting that inhibition of complex V leads to activation of the GCN2-ATF4 pathway. These results imply that the members of a unique family of RiPPs with polythioamide structure target mitochondria to induce the ISR.

Abstract
New technology for the derivatization of peptide natural products is required for drug development. Despite the recent advances in the genome sequencing technique enabling us to search for the biosynthetic genes for wide variety of natural products, the technical methods to get access to them are limited. A class of RiPPs, a recently emerged natural product family such as thioviridamide, is one of those possessing such unexplored chemical space. In this paper, we report a streamlined method to generate new thioviridamide derivatives and to assess their biological activities. Heterologous expression of 42 constructs in an engineered Streptomyces avermitilis host gave 35 designed thioviridamide derivatives, along with several unprecedented analogues. Moreover, cytotoxicity assay revealed that several derivatives showed more potent activities than those of prethioviridamide. These results indicate that this strategy can become one of the potential ways to produce supreme unnatural products.

Abstract
Bacterial natural products display astounding structural diversity, which, in turn, endows them with a remarkable range of biological activities that are of significant value to modern society. Such structural features are generated by biosynthetic enzymes that construct core scaffolds or perform peripheral modifications, and can thus define natural product families, introduce pharmacophores and permit metabolic diversification. Modern genomics approaches have greatly enhanced our ability to access and characterize natural product pathways via sequence-similarity-based bioinformatics discovery strategies. However, many biosynthetic enzymes catalyse exceptional, unprecedented transformations that continue to defy functional prediction and remain hidden from us in bacterial (meta)genomic sequence data. In this Review, we highlight exciting examples of unusual enzymology that have been uncovered recently in the context of natural product biosynthesis. These suggest that much of the natural product diversity, including entire substance classes, awaits discovery. New approaches to lift the veil on the cryptic chemistries of the natural product universe are also discussed.

Abstract
The biosynthesis of thioviridamide-like compounds has not been elucidated. Herein, we report that TvaF from the thioviridamide biosynthetic gene cluster is an FMN-dependent cysteine decarboxylase that transforms the C-terminal cysteine of precursor peptides into a thioenol motif and exhibits high substrate flexibility. We resolved the crystal structure of TvaF bound with FMN at 2.24 Å resolution. Key residues for FMN binding and catalytic activity of TvaF have been identified and evaluated by mutagenesis studies.

Abstract
A metal-free approach to N-aryl thioamides from Bunte salts and anilines in DMSO has been developed. This method tolerated a wide range of functional groups on the aromatic ring, providing an ideal way to N-aryl thioamides in good to excellent yields from cheap and easily available starting materials. A plausible mechanism was also proposed based on the X-ray single crystal diffraction, NMR and MS analyses of DMSO-concerning intermediates.

Abstract
Thioamidation as a posttranslational modification is exceptionally rare, with only a few reported natural products and exactly one known protein example (methyl-coenzyme M reductase from methane-metabolizing archaea). Recently, there has been significant progress in elucidating the biosynthesis and function of several thioamide-containing natural compounds. Separate developments in the chemical installation of thioamides into peptides and proteins have enabled cell biology and biophysical studies to advance the current understanding of natural thioamides. This review highlights the various strategies used by Nature to install thioamides in peptidic scaffolds and the potential functions of this rare but important modification. We also discuss synthetic methods used for the site-selective incorporation of thioamides into polypeptides with a brief discussion of the physicochemical implications. This account will serve as a foundation for the further study of thioamides in natural products and their various applications.
