Abstract
Emulsifiers are gradually evolving from synthetic molecules of petrochemical origin to biomolecules mainly due to health and environmental concerns. Peptides represent a type of biomolecules whose molecular structure is composed of a sequence of amino acids that can be easily tailored to have specific properties. However, the lack of knowledge about emulsifier behavior, structure-performance relationships, and the implementation of different design routes have limited the application of these peptides. Some computational and experimental approaches have tried to close this knowledge gap, but restrictions in understanding the fundamental phenomena and the limited property data availability have made the performance prediction for emulsifier peptides an area of intensive research. This study provides the concepts necessary to understand the emulsifying behavior of peptides. Additionally, a straightforward description is given of how the molecular structure and conditions of the system directly impact the peptides' ability to stabilize emulsion droplets. Moreover, the routes to design and discover novel peptides with interfacial and emulsifying activity are also discussed, along with the strategies to address some of their major pitfalls and challenges. Finally, this contribution reviews methodologies to build and use data sets containing standard properties of emulsifying peptides by looking at successful applications in different fields.

Abstract
Abstract
Background
Antimicrobial peptides are very primitive innate defense molecules of almost all organisms, from microbes to mammalians and vascular seed-bearing plants. Antimicrobial peptides of plants categorized into cysteine-rich peptides (CRPs) and others and most of the antimicrobial peptides belong to CRPs group. These peptides reported showing the great extent of protecting property against bacteria, fungi, viruses, insect, nematode, and another kind of microbes. To develop a resistant plant against pathogenic fungi, there have been several studies executed to understand the efficiency of transgenicity of these antimicrobial peptides.
Main text
Apart from the intrinsic property of the higher organism for identifying and activating microbial attack defense device, it also involves innate defense mechanism and molecules. In the current review article, apart from the structural and functional characterization of peptides defensin and thionin, we have attempted to provide a succinct overview of the transgenic development of these defense peptides, that are expressed in a constitutive and or over-expressive manner when biotic and abiotic stress inflicted. Transgenic of different peptides show different competence in plants. Most of the transgenic studies made for defensin and thionin revealed the effective transgenic capacity of these peptides.
Conclusion
There have been several studies reported successful development of transgenic plants based on peptides defensin and thionin and observed diverse level of resistance-conferring potency in different plants against phytopathogenic fungi. But due to long regulatory process, there has not been marketed any antimicrobial peptides based transgenic plants yet. However, success report state that possibly in near future transgenic plants of AMPs would be released with devoid of harmful effect, with good efficiency, reproducibility, stability, and least production cost.

Abstract
Ants (Hymenoptera, Apocrita, Aculeata, Formicoidea) comprise a well-succeeded group of animals. Like bees and wasps, ants are mostly venomous, having a sting system to deliver a mixture of bioactive organic compounds and peptides. The predatory giant ant Dinoponera quadriceps belongs to the subfamily Ponerinae that includes one of the largest known ant species in the world. In the present study, low molecular weight compounds and peptides were identified by online peptide mass fingerprint. These include neuroactive biogenic amines (histamine, tyramine, and dopamine), monoamine alkaloid (phenethylamine), free amino acids (e.g. glutamic acid and proline), free thymidine, and cytosine. To the best of our knowledge, most of these components are described for the first time in an ant venom. Multifunctional dinoponeratoxin peptide variants (pilosulin- and ponericin-like peptides) were characterized that possess antimicrobial, hemolytic, and histamine-releasing properties. These venom components, particularly peptides, might synergistically contribute to the overall venom activity and toxicity, for immobilizing live prey, and for defending D. quadriceps against aggressors, predators, and potential microbial infection.

Abstract
Nanodiscs are self-assembled discoidal nanoparticles composed of amphiphilic α-helical scaffold proteins or peptides that accumulate around the circumference of a lipid bilayer. In this study, Pxt-5, which is an antimicrobial peptide isolated from the skin of Xenopus tropicalis, and its modified peptide (Modify-Pxt-5) were synthesized by solid-phase peptide synthesis (SPPS).Their surface properties, which are an important factor in inducing nanodisc formation, were investigated by circular dichroism (CD) spectroscopy, surface tension measurement, phospholipid vesicle clearance assay, and negative-staining transmission electron microscopy (NS-TEM). The α-helicity of Pxt-5 (8.4%) improved drastically to 45.6% by four amino-acid substitutions (Modify-Pxt-5). Both the peptides, having hydrophobic and hydrophilic faces, behaved like general surfactants, and the surface activity of Modify-Pxt-5 (CAC: 9.5×10-5 M, γCAC: 30.3 mN·m-1) was much higher than that of Pxt-5 (CAC: 7.9×10-5 M, γCAC: 38.1 mN·m-1). A turbid L-α-dimyristoylphosphatidylcholine (DMPC) vesicle solution (T = 0.3%) quickly turned transparent upon addition of Pxt-5 or Modify-Pxt-5. After twelve hours, the transmittance of vesicle solution with Modify-Pxt-5 (T = 96.2%) was found to be higher than that of vesicle solution with Pxt-5 (T = 83.5%), and then the micro-solubilized solutions were observed by NS-TEM. Interestingly, nanodisc structures were found in the vicinity of DMPC vesicles in both the images, and the average diameter of the nanodiscs was 11.2 ± 6.0 nm for those containing Pxt-5 and 10.8 ± 5.8 nm for those containing Modify-Pxt-5. It was also found that Modify-Pxt-5 effectively self-assembles into nanodiscs compared to Pxt-5 without any substitutions.

Abstract
Background Mass spectrometry-guided venom peptide profiling is a powerful tool to explore novel substances from venomous animals in a highly sensitive manner. In this study, this peptide profiling approach is successfully applied to explore the venom peptides of a Japanese solitary carpenter bee, Xylocopa appendiculata (Hymenoptera: Apoidea: Apidae: Anthophila: Xylocopinae: Xylocopini). Although interesting biological effects of the crude venom of carpenter bees have been reported, the structure and biological function of the venom peptides have not been elucidated yet. Methods The venom peptide profiling of the crude venom of X. appendiculata was performed by matrix-assisted laser desorption/ionization-time of flight mass spectroscopy. The venom was purified by a reverse-phase HPLC. The purified peptides were subjected to the Edman degradation, MS/MS analysis, and/or molecular cloning methods for peptide sequencing. Biological and functional characterization was performed by circular dichroism analysis, liposome leakage assay, and antimicrobial, histamine releasing and hemolytic activity tests. Results Three novel peptides with m/z 16508, 1939.3, and 1900.3 were isolated from the venom of X. appendiculata. The peptide with m/z 16508 was characterized as a secretory phospholipase A2 (PLA2) homolog in which the characteristic cysteine residues as well as the active site residues found in bee PLA2s are highly conserved. Two novel peptides with m/z 1939.3 and m/z 1900.3 were named as Xac-1 and Xac-2, respectively. These peptides are found to be amphiphilic and displayed antimicrobial and hemolytic activities. The potency was almost the same as that of mastoparan isolated from the wasp venom. Conclusion We found three novel biologically active peptides in the venom of X. appendiculata and analyzed their molecular functions, and compared their sequential homology to discuss their molecular diversity. Highly sensitive mass analysis plays an important role in this study.

Abstract
Pxt peptides (Pxt-1 through Pxt-12) have been isolated from amphibian, Xenopus tropicalis Pxt-related peptides (Pxt-2, Pxt-5, Pxt-12, reverse Pxt-2, reverse Pxt-5 and reverse Pxt-12) with significant foaming properties were further characterized. In the physicochemical experiments, all Pxt-related peptides formed significant amphiphilic α-helices in 50% 2,2,2-trifluoroethanol by circular dichroism measurements. Among Pxt-related peptides, both Pxt-5 and reverse Pxt-5 were the most effective in reducing their surface tensions. Moreover, Pxt-2, Pxt-5 and reverse Pxt-5 produced constant surface tensions above their critical association concentrations, suggesting the micelle-like assemblies. In the biological experiments, Pxt-5 possessed the most potent hemolytic activity, while reverse Pxt-5 exhibited the most remarkable gene expression of interleukin 8 and heme oxygenase 1 and the most potent cytotoxicity in HaCaT cells. In contrast, Pxt-12 and reverse Pxt-12 were much weaker in antimicrobial assays for Gram-negative bacteria, Gram-positive bacteria and yeasts, as well as in hemolytic, cell viability and cytotoxicity assays in HaCaT cells. All Pxt-related peptides exhibited about 20-50% of the total cellular histamine release at 10(-5) M, as well as mastoparan and melittin in mast cells. Real-time polymerase chain reaction analysis confirmed the gene expressions of Pxt-5 in testis and Pxt-12 in muscle, in addition to skin, while Pxt-2 was only in skin.
