The polyketide epothilone is a potential anticancer agent that stabilizes microtubules in a similar manner to Taxol. The gene cluster responsible for epothilone biosynthesis in the myxobacteriumSorangium cellulosum was cloned and completely sequenced. It encodes six multifunctional proteins composed of a loading module, one nonribosomal peptide synthetase module, eight polyketide synthase modules, and a P450 epoxidase that converts desoxyepothilone into epothilone. Concomitant expression of these genes in the actinomyceteStreptomyces coelicolor produced epothilones A and B.Streptomyces coelicolor is more amenable to strain improvement and grows about 10-fold as rapidly as the natural producer, so this heterologous expression system portends a plentiful supply of this important agent. ...

We examined whether single nucleotide polymorphisms (SNPs) in enzymes of the folic acid pathway (folylpoly-gamma-glutamate synthetase [FPGS], gamma-glutamyl hydrolase [GGH], and methylenetetrahydrofolate reductase [MTHFR]) associate with significant adverse events (SigAE). Methods: Patients (n=319) enrolled in the Veterans Affairs RA (VARA) registry taking MTX were genotyped for HLA-DRB1-SE and the following SNPs: FPGS (rs7033913, rs10760503, rs10106), GGH (12548933, rs7010484, rs4617146, ...
Gramicidin S or Gramicidin Soviet is an antibiotic that is effective against some gram-positive and gram-negative bacteria as well as some fungi. It is a derivative of gramicidin, produced by the gram-positive bacterium Bacillus brevis. Gramicidin S is a cyclodecapeptide, constructed as two identical pentapeptides joined head to tail, formally written as cyclo(-Val-Orn-Leu-D-Phe-Pro-)2. That is to say, it forms a ring structure composed of five different amino acids, each one used twice within the structure. Another interesting point is that it utilizes two amino acids uncommon in peptides: ornithine as well as the atypical stereoisomer of phenylalanine. It is synthesized by gramicidin S synthetase. Gramicidin S biosynthetic pathway consists of two-enzyme of nonribosomal peptide synthases (NRPSs), gramicidin S synthetase I (GrsA) and gramicidin S synthetase II (GrsB), to give a product as a cyclic decapeptide. Within the biosynthetic pathway, there are total of five modules that specifically ...

Secondary metabolites are key mediators of virulence for many pathogens. Aspergillus fumigatus produces a vast array of these bioactive molecules, the biosynthesis of which is catalyzed by nonribosomal peptide synthetases (NRPSs) or polyketide synthases (PKSs). Both NRPSs and PKSs harbor carrier domains that are primed for acceptance of secondary metabolic building blocks by a phosphopantetheinyl transferase (P-pant). The A. fumigatus P-pant PptA has been shown to prime the putative NRPS Pes1 in vitro and has an independent role in lysine biosynthesis; however, its role in global secondary metabolism and its impact on virulence has not been described. Here, we demonstrate that PptA has a nonredundant role in the generation of the vast majority of detectable secondary metabolites in A. fumigatus, including the immunomodulator gliotoxin, the siderophores triacetylfusarinine C (TAFC) and ferricrocin (FC), and dihydroxy naphthalene (DHN)-melanin. We show that both the lysine and iron requirements of ...
Creating designer molecules using a combination of select domains from polyketide synthases and/or nonribosomal peptide synthetases (NRPS) continues to be a synthetic goal. However, an incomplete understanding of how protein-protein interactions and dynamics affect each of the domain functions stands as a major obstacle in the field. Of particular interest is understanding the basis for a class of methyltransferase domains (MT) that are found embedded within the adenylation domain (A) of fungal NRPS systems instead of in an end-to-end architecture. The MT domain from bassianolide synthetase (BSLS) was removed and the truncated enzyme BSLS-ΔMT was recombinantly expressed. The biosynthesis of bassianolide was abolished and N-desmethylbassianolide was produced in low yields. Co-expression of BSLS-ΔMT with standalone MT did not recover bassianolide biosynthesis. In order to address the functional implications of the protein insertion, we characterized the N-methyltransferase activity of the MT domain as

Catalyzes the decarboxylation of 4-phosphopantothenoylcysteine to 4-phosphopantetheine, a key step in coenzyme A biosynthesis. Involved in salt and osmotic tolerance, and light-regulated plant growth. Trimerization of HAL3 recruits and activates the E3 ubiquitin-protein ligase HIP1, which leads to the degradation of cell cycle suppressors, resulting in enhancement of cell division and plant growth. HAL3 function in cell division seems to be independent from its PPC decarboxylase activity.
Amino acid esters are a group of structurally diverse natural products with distinct activities. Some are synthesized through an inter-molecular esterification step catalysed by nonribosomal peptide synthetase (NRPS). In bacteria, the formation of the intra-molecular ester bond is usually catalysed by a thioesteras
Although numerous marine bacteria are known to produce antibiotics via hybrid NRPS-PKS gene clusters, none have been previously described in
The glycopeptide antibiotics (GPAs) are a structurally complex and medically important class of peptide natural products that include the clinical antibiotics vancomycin and teicoplanin. They contain a large number of non-proteinogenic amino acids and are produced by a linear non-ribosomal peptide synthetase (NRPS) machinery comprising seven modules. Furthermore, GPAs are extensively crosslinked late in their biosynthesis on the NRPS assembly line by the actions of a cascade of Cytochrome P450 enzymes, a process which contributes to the rigidity and structural complexity of these compounds. Due to the challenge of synthesising GPAs, biosynthesis remains the only means of accessing GPAs for clinical use, which makes understanding the biosynthesis of GPAs of key importance. In this presentation, I will detail results from our studies into the NRPS machinery, the P450-catalysed cyclisation cascade and the interplay of these two important biosynthetic processes during GPA biosynthesis. This includes ...
Oxidative phenol cross-linking reactions play a key role in the biosynthesis of glycopeptide antibiotics such as vancomycin. The vancomycin aglycone contains three cross-links between aromatic amino acid side-chains, which stabilize the folded backbone conformation required for binding to the target D-Ala-D-Ala dipeptide. At least the first cross-link is introduced into a peptide precursor whilst it is still bound as a thioester to a peptide carrier protein (PCP) domain (also called a thiolation domain) within the nonribosomal peptide synthetase. We described here methods for the solid-phase synthesis of peptides and their coupling to PCP domains, which may be useful for in vitro studies of cross-linking and related tailoring reactions during nonribosomal glycopeptide antibiotic biosynthesis. ...

Peptide synthetases and acyl‐CoA‐synthetases form acyl adenylates which are transferred to CoA or enzyme‐bound pantetheine. To verify the existence of an adenylate domain in peptide synthetases, a 60.8 kDa fragment of tyrocidine 1‐synthetase was constructed by a 1629 bp deletion, expressed in Escherichia coli, and characterized. The truncated multienzyme activated phenylalanine and substrate analogues with comparable kinetics as the over‐expressed synthetase, as judged by ATP‐[32P]PPi exchange reaction. Thus the N‐terminal domain resembling an acyl‐CoA‐synthetase is an autonomous structural element. This N‐terminal domain is followed by a cofactor binding domain, resembling acyl carrier proteins involved in polyketide formation.

Novel way of studying cancer may inspire new treatments. Many of the newest weapons in the war on cancer come in the form of personalized therapies that can target specific changes in an individuals tumor. By disrupting molecular processes in tumor cells, these drugs can keep the tumor from growing and spreading. At the forefront of this work are Binghamton University researchers, Susan Bane, and Susannah Gal, who are deploying a new tool in their study of an enzyme called tubulin tyrosine ligase, or TTL.. In developing these targeted therapies, scientists need to understand exactly what kind of activities within a tumor cell these drugs disturb. Bane, a professor of organic and biological chemistry, and Gal, an associate professor of biological sciences, are getting an insiders look at these cells and paying particular interest to the many cancer cells that contain less-than-normal levels of TTL.. Funded by the National Institute of General Medical Sciences, Bane and Gals work focuses on ...
D-alanine:D-alanine ligase (DDl) is an essential enzyme in bacterial cell wall biosynthesis and an important target for developing new antibiotics. It catalyzes the formation of D-alanine:D-alanine dipeptide, sequentially by using one D-alanine and one ATP as substrates for the first-half reaction, and a second D-alanine substrate to complete the reaction. Some gain of function DDl mutants can use an alternate second substrate, causing resistance to vancomycin, one of the last lines of defense against life-threatening Gram-positive infections. Here, we report the crystal structure of Staphylococcus aureus DDl (StaDDl) and its cocrystal structures with 3-chloro-2,2-dimethyl-N-[4(trifluoromethyl)phenyl]propanamide (inhibitor 1) (Ki=4 microM against StaDDl) and with ADP, one of the reaction products, at resolutions of 2.0, 2.2, and 2.6 A, respectively. The overall structure of StaDDl can be divided into three distinct domains. The inhibitor binds to a hydrophobic pocket at the interface of the ...

Wolfgang Dürheimer, Chairman and Chief Executive of Bentley Motors, said: Bentley Bentayga will be the benchmark against which all other SUVs are measured, defining a new segment - the luxury SUV.. This car is a celebration of UK manufacturing at its very best, not only reinforcing our commitment to industry in this country, job creation and significant investment, but to our home in Crewe. This is an important moment in our history, where we reflect and celebrate, but also look ahead to delivering this extraordinary car to ...
For the past two decades, we have studied and engineered enzymatic assembly lines called polyketide synthases that catalyze the biosynthesis of structurally complex and medicinally fascinating antibiotics in bacteria. An example of such an assembly line is found in the erythromycin biosynthetic pathway. Our current focus is on understanding the structure and mechanism of this polyketide synthase. At the same time, we are developing methods to decode the vast and growing number of orphan polyketide assembly lines in the sequence databases ...

Paenibacillus polymyxa is a common soil bacterium with broad range of practical applications. An important group of secondary metabolites in P polymyxa are non-ribosomal peptide and polyketide derived metabolites (NRPs/PKs). Modular non-ribosomal peptide synthetases catalyze main steps in the biosynthesis of the complex secondary metabolites. Here we report on the inactivation of an A26 Sfp-type 4-phosphopantetheinyl transferase (Sfp-type PPTase). The inactivation of the gene resulted in loss of NRPs/PKs production. In contrast to the former Bacillus spp. model the mutant strain compared to wild type showed greatly enhanced biofilm formation ability. A26 Delta sfp biofilm promotion is directly mediated by NRPs/PKs, as exogenous addition of the wild type metabolite extracts restores its biofilm formation level. Wheat inoculation with bacteria that had lost their Sfp-type PPTase gene resulted in two times higher plant survival and about three times increased biomass under severe drought stress ...

Penicillins (Penams) and cephalosporins (cephems) are beta-lactam antibiotics containing 6-aminopenicillanate (6-APA) and 7-aminocephalosporanate (7-ACA) nuclei, respectively. 6-APA and 7-ACA are key intermediates for a variety of semisynthetic penicillin and cephalosporin derivatives. Penicillins are produced only by fungi, while cephalosporins (including cephamycins) are produced by fungi and bacteria. Both antibiotics are synthesized from L-2-aminoadipate, L-cysteine and L-valine through a common pathway. It starts with the condensation of these three amino acids by the non-ribosomal peptide synthetase to form the tripeptide delta-(L-2-aminoadipyl)-L-cysteinyl-D-valine (ACV). The linear ACV tripeptide is then converted to bicyclic isopenicillin N by isopenicillin N synthase, in which the beta-lactam ring is formed. Isopenicillin N is the branch point of penicillin [MD:M00672] and cephalosporin [MD:M00673] pathways ...
Despite remarkable medical advances, including improved sanitation, effective vaccines, and antibiotics, bacterial infections remain a serious threat to human health. Annually, over 17 million people succumb to bacterial infections, with an increasing proportion due to antibiotic resistance. Therefore, there is urgent and continuous need for new antibiotics. Small molecule metabolites from microbes have been a highly productive source of chemical matter that ultimately led to most of todays clinically used antibiotics. Many of these natural products are derived from polyketide synthase (PKS) or non-ribosomal peptide synthetase (NRPS) families, including well-known antibiotics such as the beta-lactams, tetracyclines, macrolides, and glycopeptides. With the rising resistance to these proven antibiotic classes, alternative sources of antibiotics must be discovered. The ribosomally synthesized and post-translationally modified peptides (RiPPs) have been attracting interest as one such source of ...

Nonribosomal peptide synthetases (NRPSs) and polyketide synthases (PKSs) are large enzymes responsible for the biosynthesis of medically and ecologically important secondary metabolites. In a previous report, we described a proteomics approach to screen for expressed NRPSs or PKSs from bacteria with or without sequenced genomes. Here we used this proteome mining approach to discover a novel natural product arising from rare adenylation (A) and reductase (Red) domains in its biosynthetic machinery. We also cloned the entire gene cluster and elucidated the biosynthesis of the new compound, which is produced by an unsequenced Bacillus sp. isolated from soil collected in Koran, Louisiana.. ...
Darcie Long, a fourth-year in the Chemistry-Biology Interface Program and one of the authors of this study, explained that while most of the clinically relevant β-lactam antibiotics have two fused structures, a different class, called moncyclic antibiotics, only has one ring structure.. Although most antibiotics are bicyclic, Long says the monocyclic antibiotics are of increasing interest because of their relative resistance to metalloproteases and β-lactamases, which are enzymes involved in conferring antibiotic resistance to some pathogenic bacteria.. Therefore, to better understand this single-ring class of antibiotics, the authors investigated the ring formation in one specific family: norcardicin.. Long and lead author Nicole Gaudelli worked together on all of the benchwork that led to the discovery of the mechanism. They found how the nonribosomal peptide synthetases (NRPSs) were able to create a ring structure in the norcardicin family. Intriguingly, this enzyme has been identified in ...
The ≈80-kb pksX gene cluster in Bacillus subtilis encodes an unusual hybrid polyketide/nonribosomal peptide synthase that has been linked to the production of the uncharacterized antibiotic bacillaene. Multiple copies of this synthase, each similar in size to the ribosome, assemble into a single organelle-like complex with a mass of tens to hundreds of megadaltons. The resource requirements of the assembled megacomplex suggest that bacillaene has an important biological role. By coupling a differential NMR spectroscopic technique with genetically manipulated strains of B. subtilis, we were able to characterize the structure of this unusual secondary metabolite, which could not be predicted by using bioinformatic analysis. We report that bacillaene is a linear molecule with two amide bonds: the first links an α-hydroxy carboxylic acid to a ω-amino carboxylic acid containing a conjugated hexaene, and the second links the hexaene-containing carboxylic acid to an (ω-1) amino carboxylic acid ...

CB30900 is a novel, potent thymidylate synthase inhibitor which can not be polyglutamated and may be active in cancers expressing low or defective folylpolyglutamate synthetase. Pharmacokinetics were studied in mouse tumors and tissues after bolus or infusion protocols. Elimination was triphasic after 100 mg kg-1 i.v. (T 1/2 alpha, 2.8 min; T 1/2 beta, 19.1 min and T 1/2 gamma, 4.1 hr). Peak concentrations were 716 microM; clearance, 1.19 ml g-1 hr-1; and area under the curve (AUC 0-2 hr), 131 microM hr. Biphasic elimination occurred after i.p. administration and was comparable to the i.v. route giving complete i.p. bioavailability. Kidney concentrations were similar to plasma (AUC 0-2 hr, 84.3 microM hr). CB30900 concentrations in the gut increased steadily with time (AUC 0-2 hr, 645 microM hr) and liver drug concentrations were 7-fold greater than plasma (AUC 0-2 hr, 847 microM hr). Peak tumor concentrations occurred at 30 min and were 27% of plasma concentrations, but tumor drug clearance was ...

Dear Gemba Coach. Which is best for a lean environment, a U-shaped cell or assembly line? Why? This is a question that comes up quite often - and the pros and cons of cells versus lines have been discussed at length, so lets look at this from another angle: before you kaizen your existing operation, what is the problem youre trying to solve?. Whether in a straight line (I-cell) or a U-shaped cell, lean thinking highlights two fundamental problems: ease of use and flexibility. The first issue is that operators have to be able to work safely, intuitively, and keep to quality and takt time requirements. The second is that operators have to be able to deal with continual change in terms of mix, volume, and new product introduction.. Issue number one is to keep the operator working in a strike zone, to use a baseball expression. Imagine a window in front of each worker where all the work happens. To visualize this, start by looking at feet movement (steps and rotations), then hand movements ...

People make use of quite a few chemical reactions to breakdown tissue protein; through the mouth and thru the digestive tract, which in the end will allow your body to receive a steady stream of amino acids which might be appropriately processed for max utilization. You see, On the subject of amino acid absorption, flooding the bloodstream can result in protein to become squandered--because the human processing components cannot keep up. Imagine it like a muscle mass-setting up assembly line which is turned on much too rapidly, While amino acids (or building blocks) are relocating so fast down the assembly line (bloodstream) that a entire muscle mass protein cannot be designed ...

Needing to optically isolate RS232. Easily done, done it before, problem this go around is I need to do the isolation on the RS232 voltage side. I.e. after the MAX232 chip. Looking for a point to where to get some ideas on doing the isolation on the RS232 voltage side not the TTL side. The RS232 link is two MAX232 chips tied together each converting back to TTL levels like they do so well. Needing the isolation between the two MAX232s and no room for a commonly acquired isolator product needing to do it on the chip level myself for space requirements ...

This is subsequent to a complaint by the council to the ...
