Host Defense Peptide Piscidin and Yeast-Derived Glycolipid Exhibit Synergistic Antimicrobial Action through Concerted Interactions with Membranes. JACS AU 2023; 3:3345-3365. [PMID: 38155643 PMCID: PMC10751773 DOI: 10.1021/jacsau.3c00506] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 09/25/2023] [Accepted: 09/29/2023] [Indexed: 12/30/2023]
Abstract
Developing new antimicrobials as alternatives to conventional antibiotics has become an urgent race to eradicate drug-resistant bacteria and to save human lives. Conventionally, antimicrobial molecules are studied independently even though they can be cosecreted in vivo. In this research, we investigate two classes of naturally derived antimicrobials: sophorolipid (SL) esters as modified yeast-derived glycolipid biosurfactants that feature high biocompatibility and low production cost; piscidins, which are host defense peptides (HDPs) from fish. While HDPs such as piscidins target the membrane of pathogens, and thus result in low incidence of resistance, SLs are not well understood on a mechanistic level. Here, we demonstrate that combining SL-hexyl ester (SL-HE) with subinhibitory concentration of piscidins 1 (P1) and 3 (P3) stimulates strong antimicrobial synergy, potentiating a promising therapeutic window. Permeabilization assays and biophysical studies employing circular dichroism, NMR, mass spectrometry, and X-ray diffraction are performed to investigate the mechanism underlying this powerful synergy. We reveal four key mechanistic features underlying the synergistic action: (1) P1/3 binds to SL-HE aggregates, becoming α-helical; (2) piscidin-glycolipid assemblies synergistically accumulate on membranes; (3) SL-HE used alone or bound to P1/3 associates with phospholipid bilayers where it induces defects; (4) piscidin-glycolipid complexes disrupt the bilayer structure more dramatically and differently than either compound alone, with phase separation occurring when both agents are present. Overall, dramatic enhancement in antimicrobial activity is associated with the use of two membrane-active agents, with the glycolipid playing the roles of prefolding the peptide, coordinating the delivery of both agents to bacterial surfaces, recruiting the peptide to the pathogenic membranes, and supporting membrane disruption by the peptide. Given that SLs are ubiquitously and safely used in consumer products, the SL/peptide formulation engineered and mechanistically characterized in this study could represent fertile ground to develop novel synergistic agents against drug-resistant bacteria.

Abstract
Well-hydrated phospholipid bilayers provide a near-native environment for membrane proteins. They enable the preparation of chemically-defined samples suitable for NMR and other spectroscopic experiments that reveal the structure, dynamics, and functional interactions of the proteins at atomic resolution. The synthetic polymer styrene maleic acid (SMA) can be used to prepare detergent-free samples that form macrodiscs with diameters greater than 30 nm at room temperature, and spontaneously align in the magnetic field of an NMR spectrometer at temperatures above 35 °C. Here we show that magnetically aligned macrodiscs are particularly well suited for solid-state NMR experiments of membrane proteins because the SMA-lipid assembly both immobilizes the embedded protein and provides uniaxial order for oriented sample (OS) solid-state NMR studies. We show that aligned macrodiscs incorporating four different membrane proteins with a wide range of sizes and topological complexity yield high-resolution OS solid-state NMR spectra. The work is dedicated to Michelle Auger who made key contributions to the field of membrane and membrane protein biophysics.

Abstract
Crystal structures of the dipeptide Boc-12-Crown-4-L-DOPA-Gly-OMe (chi) and Boc-12-Crown-4-D/L-DOPA-Gly-OMe (rac) were solved by single crystal X-ray diffraction. Analysis of the packing differences in the crystal reveals that the presence of a water molecule in chi enables intermolecular contacts with the solvent that result in a different conformation of the dipeptide backbone itself. An uncommon N-H…N interaction stabilizes the peptide in its solid state.

Abstract
The Bcl-2 family of proteins is crucial for apoptosis regulation. Members of this family insert through a specific C-terminal anchoring transmembrane domain (TMD) in the mitochondrial outer membrane where they hierarchically interact to determine cell fate. While the mitochondrial membrane has been proposed to actively participate in these protein-protein interactions, the influence of the TMD in the membrane-mediated interaction is poorly understood. Synthetic peptides (TMD-pepts) corresponding to the putative TMD of antiapoptotic (Bcl-2, Bcl-xL, Bcl-w, and Mcl-1) and pro-apoptotic (Bax, Bak) members were synthesized and characterized. TMD-pepts bound more efficiently to mitochondria-like bilayers than to plasma membrane-like bilayers, and higher binding correlated with greater membrane perturbation. The Bcl-2 TMD peptides promoted mitochondrial outer membrane permeabilization (MOMP) and cytochrome c release from isolated mitochondria and different cell lines. TMD-pepts exhibited nonapoptotic pro-death activity when apoptosis stimuli were absent. In addition, the peptides enhanced the apoptotic pathway induced by chemotherapeutic agents in cotreatment. Overall, the membrane perturbation effects of the TMD-pepts observed in the present study open the way for their use as new chemical tools to sensitize tumor cells to chemotherapeutic agents, in accordance with the concept of mitochondria priming.

Abstract
We have investigated in the present study the effect of both non-selective and selective cationic 14-mer peptides on the lipid orientation of DMPC bilayers by (31)P solid-state nuclear magnetic resonance (NMR) spectroscopy. Depending on the position of substitution, these peptides adopt mainly either an α-helical structure able to permeabilize DMPC and DMPG vesicles (non-selective peptides) or an intermolecular β-sheet structure only able to permeabilize DMPG vesicles (selective peptides). Several systems have been investigated, namely bilayers mechanically oriented between glass plates as well as bicelles oriented with their normal perpendicular or parallel to the external magnetic field. The results have been compared with spectral simulations with the goal of elucidating the difference in the interaction of these two types of peptides with zwitterionic lipid bilayers. The results indicate that the perturbation induced by selective peptides is much greater than that induced by non-selective peptides in all the lipid systems investigated, and this perturbation has been associated to the aggregation of the selective β-sheet peptides in these systems. On the other hand, the oriented lipid spectra obtained in the presence of non-selective peptides suggest the presence of toroidal pores. This article is part of a Special Issue entitled: Interfacially Active Peptides and Proteins. Guest Editors: William C. Wimley and Kalina Hristova.

Abstract
Human β‑defensin 6 (DEFB106) is an antimicrobial peptide expressed in the epididymis, testis and lung, which indicates that DEFB106 may be involved in innate immunity and fertility. However, as a β‑defensin, this protein has not been well characterized. Using an intein‑mediated fusion expression system, the recombinant DEFB106 was expressed and purified (yield, 3‑5 mg/l) under optimized conditions. The purified protein was characterized using mass spectrometry and circular dichroism spectroscopy. The measured molecular weight was consistent with its theoretical value and the predominant secondary structure was β‑sheet, the common structure of β‑defensin family members. The purified DEFB106 showed antimicrobial activity against not only Escherichia coli (E. coli) and Candida albicans (C. albicans) SC5314, but also Staphylococcus aureus (S. aureus) CMCC26003. Furthermore, it exhibited a high affinity for heparin and lipopolysaccharide. In addition, it was determined that native DEFB106 was located in the epididymis, bone marrow and skin. These observations may aid in the determination of the physiological and pathological functions of DEFB106.

Abstract
We have previously shown that leucine to lysine substitution(s) in neutral synthetic crown ether containing 14-mer peptide affect the peptide structure and its ability to permeabilize bilayers. Depending on the substitution position, the peptides adopt mainly either a α-helical structure able to permeabilize dimyristoylphosphatidylcholine (DMPC) and dimyristoylphosphatidylglycerol (DMPG) vesicles (nonselective peptides) or an intermolecular β-sheet structure only able to permeabilize DMPG vesicles (selective peptides). In this study, we have used a combination of solid-state NMR and Fourier transform infrared spectroscopy to investigate the effects of nonselective α-helical and selective intermolecular β-sheet peptides on both types of bilayers. (31)P NMR results indicate that both types of peptides interact with the headgroups of DMPC and DMPG bilayers. (2)H NMR and Fourier transform infrared results reveal an ordering of the hydrophobic core of bilayers when leakage is noted, i.e., for DMPG vesicles in the presence of both types of peptides and DMPC vesicles in the presence of nonselective peptides. However, selective peptides have no significant effect on the ordering of DMPC acyl chains. The ability of these 14-mer peptides to permeabilize lipid vesicles therefore appears to be related to their ability to increase the order of the bilayer hydrophobic core.

Abstract
It has previously been shown that an amphipathic de novo designed peptide made of 10 leucines and four phenylalanines substituted with crown ethers induces vesicle leakage without selectivity. To gain selectivity against negatively charged dimyristoylphosphatidylglycerol (DMPG) bilayers, one or two leucines of the peptide were substituted with positively charged residues at each position. All peptides induce significant calcein leakage of DMPG vesicles. However, some peptides do not induce significant leakage of zwitterionic dimyristoylphosphatidylcholine vesicles and are thus active against only bacterial model membranes. The intravesicular leakage is induced by pore formation instead of membrane micellization. Nonselective peptides are mostly helical, while selective peptides mainly adopt an intermolecular β-sheet structure. This study therefore demonstrates that the position of the lysine residues significantly influences the secondary structure and bilayer selectivity of an amphipathic 14-mer peptide, with β-sheet peptides being more selective than helical peptides.

Abstract
This critical review covers progress with synthetic transport systems, particularly ion channels and pores, between January 2006 and December 2009 in a comprehensive manner. This is the third part of a series launched in the year 2000, covering a rich collection of structural and functional motifs that should appeal to a broad audience of non-specialists, including to organic, biological, supramolecular and polymer chemists. Impressive breakthroughs have been achieved over the past four years in part because of a fruitful expansion toward new types of interactions, including metal-organic, π-π, aromatic electron donor-acceptor, anion-π or anion-macrodipole interactions as well as dynamic covalent bonds (169 references).

Abstract
Due to the ubiquitous presence of polysaccharide moieties on bacterial surfaces, it is hypothesised that a peptide-saccharide interaction plays a key role during the recognition of invading microorganisms by beta-defensins. We have employed different gas-phase methods to investigate these interactions. This manuscript describes: an MS-based titration assay measuring the gas-phase binding of ten beta-defensin related peptides to a sulfated disaccharide derived from heparin (HDD); ion mobility-mass spectrometry-determined collision cross sections of 3 peptides (both free and binding HDD); and results from molecular modelling with the aim of reconciling some of our experimental observations. We observe a clear qualitative correlation between the antimicrobial activity of several beta-defensins and related peptides and their gas-phase binding to a heparin-derived disaccharide (HDD). Four of the ten peptides show >100 micromolar K(d) values with HDD, and no bacteriocidal activity, illustrating that HDD binding correlates with peptide antimicrobial activity. For five of the remaining six peptides, bacteriocidal activity was re-measured with HDD present. For the peptides containing intramolecular disulfide bonds in two out of five, bacteriocidal activity was reduced approximately 10-fold; for the remaining three peptides, which lack intramolecular disulfide bonds, HDD addition had little effect on bacteriocidal activity. The latter results are suggested to arise from the greater degree of flexibility imparted by the removal of disulfide bonds giving the peptides the ability to envelope HDD and assume a "defensin-like" fold. Thus gas-phase analysis is put forward as a powerful tool for assessing the properties of antimicrobial peptides providing valuable insights in the mechanism of antimicrobial inhibition.

Abstract
Catechins are the principle polyphenolic compounds in green tea; the four major compounds identified are epicatechin (EC), epigallocatechin (EGC), epicatechin gallate (ECg) and epigallocatechin gallate (EGCg). Tea catechins tend to attach externally to their targets, such as viral envelopes, cell membranes, or the surface of low-density lipoproteins. In order to further our understanding of the molecular mobility of these compounds in cells, we examined the interaction of tea catechins with lipid membranes using solid-state NMR techniques. Our previous work indicated that the EGCg molecule is incorporated into lipid bilayers in a unique orientation. However, the detailed configuration, orientation, and dynamics of EGCg in lipid bilayers have not been well-characterized. Here, we investigated the orientation and dynamics of EGCg incorporated into multi-lamellar vesicles (MLVs) and bicelles using solid-state NMR spectroscopy.

Abstract
Many natural alpha-helical amphiphilic peptides are known to have lytic activity toward different cells. Herein, we describe the synthesis and the characterization of synthetic alpha-helical amphiphilic peptide nanostructures containing crown ethers, as well as the modulation of their cytolytic activity by adding different acidic dipeptide chains at the N- or C-terminus.
