Nonribosomal peptides for iron acquisition: pyochelin biosynthesis as a case study.

ABSTRACT: Microbes synthesize small, iron-chelating molecules known as siderophores to acquire iron from the environment. One way siderophores are generated is by nonribosomal peptide synthetases (NRPSs). The bioactive peptides generated by NRPS enzymes have unique chemical features, which are incorporated by accessory and tailoring domains or proteins. The first part of this review summarizes recent progress in NRPS structural biology. The second part uses the biosynthesis of pyochelin, a siderophore from Pseudomonas aeruginosa, as a case study to examine enzymatic methods for generating the observed diversity in NRPS-derived natural products.

Biosynthesis and engineering of the nonribosomal peptides with a C-terminal putrescine.

Project description:The broad bioactivities of nonribosomal peptides rely on increasing structural diversity. Genome mining of the Burkholderiales strain Schlegelella brevitalea DSM 7029 leads to the identification of a class of dodecapeptides, glidonins, that feature diverse N-terminal modifications and a uniform putrescine moiety at the C-terminus. The N-terminal diversity originates from the wide substrate selectivity of the initiation module. The C-terminal putrescine moiety is introduced by the unusual termination module 13, the condensation domain directly catalyzes the assembly of putrescine into the peptidyl backbone, and other domains are essential for stabilizing the protein structure. Swapping of this module to another two nonribosomal peptide synthetases leads to the addition of a putrescine to the C-terminus of related nonribosomal peptides, improving their hydrophilicity and bioactivity. This study elucidates the mechanism for putrescine addition and provides further insights to generate diverse and improved nonribosomal peptides by introducing a C-terminal putrescine.

ClbP is a prototype of a peptidase subgroup involved in biosynthesis of nonribosomal peptides.

Project description:The pks genomic island of Escherichia coli encodes polyketide (PK) and nonribosomal peptide (NRP) synthases that allow assembly of a putative hybrid PK-NRP compound named colibactin that induces DNA double-strand breaks in eukaryotic cells. The pks-encoded machinery harbors an atypical essential protein, ClbP. ClbP crystal structure and mutagenesis experiments revealed a serine-active site and original structural features compatible with peptidase activity, which was detected by biochemical assays. Ten ClbP homologs were identified in silico in NRP genomic islands of closely and distantly related bacterial species. All tested ClbP homologs were able to complement a clbP-deficient E. coli mutant. ClbP is therefore a prototype of a new subfamily of extracytoplasmic peptidases probably involved in the maturation of NRP compounds. Such peptidases will be powerful tools for the manipulation of NRP biosynthetic pathways.

Stuffed Methyltransferase Catalyzes the Penultimate Step of Pyochelin Biosynthesis.

Project description:Nonribosomal peptide synthetases use tailoring domains to incorporate chemical diversity into the final natural product. A structurally unique set of tailoring domains are found to be stuffed within adenylation domains and have only recently begun to be characterized. PchF is the NRPS termination module in pyochelin biosynthesis and includes a stuffed methyltransferase domain responsible for S-adenosylmethionine (AdoMet)-dependent N-methylation. Recent studies of stuffed methyltransferase domains propose a model in which methylation occurs on amino acids after adenylation and thiolation rather than after condensation to the nascent peptide chain. Herein, we characterize the adenylation and stuffed methyltransferase didomain of PchF through the synthesis and use of substrate analogues, steady-state kinetics, and onium chalcogen effects. We provide evidence that methylation occurs through an SN2 reaction after thiolation, condensation, cyclization, and reduction of the module substrate cysteine and is the penultimate step in pyochelin biosynthesis.

Isolation and characterization of Burkholderia cenocepacia mutants deficient in pyochelin production: pyochelin biosynthesis is sensitive to sulfur availability.

Project description:The opportunistic pathogen Burkholderia cenocepacia produces the yellow-green fluorescent siderophore, pyochelin. To isolate mutants which do not produce this siderophore, we mutagenized B. cenocepacia with the transposon mini-Tn5Tp. Two nonfluorescent mutants were identified which were unable to produce pyochelin. In both mutants, the transposon had integrated into a gene encoding an orthologue of CysW, a component of the sulfate/thiosulfate transporter. The cysW gene was located within a putative operon encoding other components of the transporter and a polypeptide exhibiting high homology to the LysR-type regulators CysB and Cbl. Sulfate uptake assays confirmed that both mutants were defective in sulfate transport. Growth in the presence of cysteine, but not methionine, restored the ability of the mutants to produce pyochelin, suggesting that the failure to produce the siderophore was the result of a depleted intracellular pool of cysteine, a biosynthetic precursor of pyochelin. Consistent with this, the wild-type strain did not produce pyochelin when grown in the presence of lower concentrations of sulfate that still supported efficient growth. We also showed that whereas methionine and certain organosulfonates can serve as sole sulfur sources for this bacterium, they do not facilitate pyochelin biosynthesis. These observations suggest that, under conditions of sulfur depletion, cysteine cannot be spared for production of pyochelin even under iron starvation conditions.

A strategy for the identification of patterns in the biosynthesis of nonribosomal peptides by Betaproteobacteria species.

Project description:Nonribosomal peptides have an important pharmacological role due to their extensive biological properties. The singularities in the biosynthesis of these natural products allowed the development of genome-mining strategies which associate them to their original biosynthetic gene clusters. Generally, these compounds present complex architectures that make their identification difficult. Based on these evidences, genomes from species of the class Betaproteobacteria were studied with the purpose of finding biosynthetic similarities among them. These organisms were applied as templates due to their large number of biosynthetic gene clusters and the natural products isolated from them. The strategy for Rapid Identification of Nonribosomal Peptides Portions (RINPEP) proposed in this work was built by reorganizing the data obtained from antiSMASH and NCBI with a product-centered way. The verification steps of RINPEP comprehended the fragments of existent compounds and predictions obtained in silico with the purpose of finding common subunits expressed by different genomic sequences. The results of this strategy revealed patterns in a global overview of the biosynthesis of nonribosomal peptides by Betaproteobacteria.

Essential PchG-dependent reduction in pyochelin biosynthesis of Pseudomonas aeruginosa.

Project description:The biosynthetic genes pchDCBA and pchEF, which are known to be required for the formation of the siderophore pyochelin and its precursors salicylate and dihydroaeruginoate (Dha), are clustered with the pchR regulatory gene on the chromosome of Pseudomonas aeruginosa. The 4.6-kb region located downstream of the pchEF genes was found to contain three additional, contiguous genes, pchG, pchH, and pchI, probably forming a pchEFGHI operon. The deduced amino acid sequences of PchH and PchI are similar to those of ATP binding cassette transport proteins with an export function. PchG is a homolog of the Yersinia pestis and Y. enterocolitica proteins YbtU and Irp3, which are involved in the biosynthesis of yersiniabactin. A null mutation in pchG abolished pyochelin formation, whereas mutations in pchH and pchI did not affect the amounts of salicylate, Dha, and pyochelin produced. The pyochelin biosynthetic genes were expressed from a vector promoter, uncoupling them from Fur-mediated repression by iron and PchR-dependent induction by pyochelin. In a P. aeruginosa mutant lacking the entire pyochelin biosynthetic gene cluster, the expressed pchDCBA and pchEFG genes were sufficient for salicylate, Dha, and pyochelin production. Pyochelin formation was also obtained in the heterologous host Escherichia coli expressing pchDCBA and pchEFG together with the E. coli entD gene, which provides a phosphopantetheinyl transferase necessary for PchE and PchF activation. The PchG protein was purified and used in combination with PchD and phosphopantetheinylated PchE and PchF in vitro to produce pyochelin from salicylate, L-cysteine, ATP, NADPH, and S-adenosylmethionine. Based on this assay, a reductase function was attributed to PchG. In summary, this study completes the identification of the biosynthetic genes required for pyochelin formation from chorismate in P. aeruginosa.

Structural pattern matching of nonribosomal peptides.

Project description:BackgroundNonribosomal peptides (NRPs), bioactive secondary metabolites produced by many microorganisms, show a broad range of important biological activities (e.g. antibiotics, immunosuppressants, antitumor agents). NRPs are mainly composed of amino acids but their primary structure is not always linear and can contain cycles or branchings. Furthermore, there are several hundred different monomers that can be incorporated into NRPs. The NORINE database, the first resource entirely dedicated to NRPs, currently stores more than 700 NRPs annotated with their monomeric peptide structure encoded by undirected labeled graphs. This opens a way to a systematic analysis of structural patterns occurring in NRPs. Such studies can investigate the functional role of some monomeric chains, or analyse NRPs that have been computationally predicted from the synthetase protein sequence. A basic operation in such analyses is the search for a given structural pattern in the database.ResultsWe developed an efficient method that allows for a quick search for a structural pattern in the NORINE database. The method identifies all peptides containing a pattern substructure of a given size. This amounts to solving a variant of the maximum common subgraph problem on pattern and peptide graphs, which is done by computing cliques in an appropriate compatibility graph.ConclusionThe method has been incorporated into the NORINE database, available at http://bioinfo.lifl.fr/norine. Less than one second is needed to search for a pattern in the entire database.

rBAN: retro-biosynthetic analysis of nonribosomal peptides.

Project description:Proteinogenic and non-proteinogenic amino acids, fatty acids or glycans are some of the main building blocks of nonribsosomal peptides (NRPs) and as such may give insight into the origin, biosynthesis and bioactivities of their constitutive peptides. Hence, the structural representation of NRPs using monomers provides a biologically interesting skeleton of these secondary metabolites. Databases dedicated to NRPs such as Norine, already integrate monomer-based annotations in order to facilitate the development of structural analysis tools. In this paper, we present rBAN (retro-biosynthetic analysis of nonribosomal peptides), a new computational tool designed to predict the monomeric graph of NRPs from their atomic structure in SMILES format. This prediction is achieved through the "in silico" fragmentation of a chemical structure and matching the resulting fragments against the monomers of Norine for identification. Structures containing monomers not yet recorded in Norine, are processed in a "discovery mode" that uses the RESTful service from PubChem to search the unidentified substructures and suggest new monomers. rBAN was integrated in a pipeline for the curation of Norine data in which it was used to check the correspondence between the monomeric graphs annotated in Norine and SMILES-predicted graphs. The process concluded with the validation of the 97.26% of the records in Norine, a two-fold extension of its SMILES data and the introduction of 11 new monomers suggested in the discovery mode. The accuracy, robustness and high-performance of rBAN were demonstrated in benchmarking it against other tools with the same functionality: Smiles2Monomers and GRAPE.

Emulating nonribosomal peptides with ribosomal biosynthetic strategies.

Project description:Peptide natural products are important lead structures for human drugs and many nonribosomal peptides possess antibiotic activity. This makes them interesting targets for engineering approaches to generate peptide analogues with, for example, increased bioactivities. Nonribosomal peptides are produced by huge mega-enzyme complexes in an assembly-line like manner, and hence, these biosynthetic pathways are challenging to engineer. In the past decade, more and more structural features thought to be unique to nonribosomal peptides were found in ribosomally synthesised and posttranslationally modified peptides as well. These streamlined ribosomal pathways with modifying enzymes that are often promiscuous and with gene-encoded precursor proteins that can be modified easily, offer several advantages to produce designer peptides. This review aims to provide an overview of recent progress in this emerging research area by comparing structural features common to both nonribosomal and ribosomally synthesised and posttranslationally modified peptides in the first part and highlighting synthetic biology strategies for emulating nonribosomal peptides by ribosomal pathway engineering in the second part.

Single-molecule Study on the Interactions between Cyclic Nonribosomal Peptides and Protein Nanopore.

Project description:Nonribosomal peptides (NRPs) are a type of secondary metabolites mostly originated from microorganisms such as bacteria and fungi. Their proteolytic stability, highly selective bioactivity, and microorganism-specificity have made them an attractive source of drugs for the pharmaceutical industry. Herein, with microcystins (MCs) as a NRP model, we, for the first time, proposed a sensitive method to study the interactions between NRPs and the protein nanopore. Due to the large molecular size (~3 nm diameter) of MCs and their net negative charges, MCs failed to translocate through the α-hemolysin (α-HL) protein channel. Our results demonstrated that the biomolecular interaction of MC-α-HL protein was significantly affected by the applied potential bias. The constant blockage amplitude in the voltage-dependent studies indicated that the current modulation events were dominantly contributed to the bumping interaction between MCs and the α-HL protein under the electrophoretic force. The mean residence time of the bumping events exhibited a two-stage decrease (from 1.90 ms to 1.02 ms, and from 1.02 ms to 0.69 ms) at the threshold voltages of -70 mV and -100 mV, respectively. Using our strategy (i.e., based on their electrophoretic driven interaction with the α-HL protein pore), discrimination of different MC molecules (MC-LR, MC-RR, MC-YR and linear analog) with varied branched residues could be accomplished. This work should provide an insight in developing a rapid and effective method for the identification of cyclic NRPs as valuable biomarkers for fungal infections.
