Zilberstein G, Zilberstein S, Righetti PG. Holy Grail possibly made from clay. Electrophoresis 2024; 45:1443-1449. [PMID: 38234009 DOI: 10.1002/elps.202300249] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2023] [Revised: 01/06/2024] [Accepted: 01/09/2024] [Indexed: 01/19/2024]
Abstract
The main goal of the work was to find biochemical protein markers specific for grapes and wine in ancient amphorae shards and fermentation pools. Grape-specific proteins are more reliable markers than tartaric acid and other small organic acids (tartaric acid natural source are not only grape but also apple, mango, and other plants). The Yavne winery (located in the Central District of Israel) is stated to be the largest known wine production complex from the Byzantine period (ca. 1500 years ago). The site has been excavated recently, and a number of wine jar have been recovered. We have applied our ethylene vinyl acetate (EVA) (EVA studded with strong cation and anion exchangers) diskettes to the inner surface of a number of jars, thus capturing residual grape proteins therein. Via mass spectrometry analyses, we have been able to identify four grape and three yeast proteins. This has been possible because the EVA films, applied to such surfaces, are able to harvest and concentrate any trace species, rendering them amenable to instrumental analysis. Our analysis makes it possible to propose an explanation for the Holy Grail phenomenon as a dish in which wine or water begins to smell pleasant. We attribute this to the slow release of terpenes, aldehydes, and ketones from the clay walls of pottery. After digital modeling, we identified that "scallop-shaped" niches in winery were used for the condensation of high percentage alcohol by passive evaporation from fermentation tanks.

Count Dracula Resurrected: Proteomic Analysis of Vlad III the Impaler's Documents by EVA Technology and Mass Spectrometry. Anal Chem 2023; 95:12732-12744.

Abstract
The interest of scientists in analyzing items of World Cultural Heritage has been exponentially increasing since the beginning of the new millennium. These studies have grown considerably in tandem with the development and use of sophisticated and sensitive technologies such as high-resolution mass spectrometry (MS) and the non-invasive and non-damaging technique, known under the acronym EVA (ethylene-vinyl acetate). Here, we report the results of the MS characterization of the peptides and proteins harvested by the EVA technology applied to three letters written in 1457 and 1475 by the voivode of Wallachia, Vlad III, also known as Vlad the Impaler, or Vlad Dracula. The discrimination of the "original" endogenous peptides from contaminant ones was obtained by monitoring their different levels of deamidation and of other diagenetic chemical modifications. The characterization of the ancient proteins extracted from these documents allowed us to explore the environmental conditions, in the second half of the 15th century, of the Wallachia, a region considered as a meeting point for soldiers, migrants, and travelers that probably carried not only trade goods and cultural traditions but also diseases and epidemics. In addition, the identification of many human peptides and proteins harvested from the letters allowed us to uncover more about Vlad Dracula the Impaler. Particularly, the experimental data show that he probably suffered from inflammatory processes of the respiratory tract and/or of the skin. In addition, proteomics data, although not exhaustive, suggest that, according to some stories, he might also have suffered from a pathological condition called hemolacria, that is, he could shed tears admixed with blood. It is worth noting that more medieval people may have touched these documents, which cannot be denied, but it is also presumable that the most prominent ancient proteins should be related to Prince Vlad the Impaler, who wrote and signed these letters. The data have been deposited to the ProteomeXchange with the identifier ⟨PXD041350⟩.

Abstract
This review explains the strategies behind genomics, proteomics, metabolomics, metallomics and isotopolomics approaches and their applicability to written artefacts. The respective sub-chapters give an insight into the analytical procedure and the conclusions drawn from such analyses. A distinction is made between information that can be obtained from the materials used in the respective manuscript and meta-information that cannot be obtained from the manuscript itself, but from residues of organisms such as bacteria or the authors and readers. In addition, various sampling techniques are discussed in particular, which pose a special challenge in manuscripts. The focus is on high-resolution, non-targeted strategies that can be used to extract the maximum amount of information about ancient objects. The combination of the various omics disciplines (panomics) especially offers potential added value in terms of the best possible interpretations of the data received. The information obtained can be used to understand the production of ancient artefacts, to gain impressions of former living conditions, to prove their authenticity, to assess whether there is a toxic hazard in handling the manuscripts, and to be able to determine appropriate measures for their conservation and restoration.

Abstract
Paleoproteomics, the study of ancient proteins, is a rapidly growing field at the intersection of molecular biology, paleontology, archaeology, paleoecology, and history. Paleoproteomics research leverages the longevity and diversity of proteins to explore fundamental questions about the past. While its origins predate the characterization of DNA, it was only with the advent of soft ionization mass spectrometry that the study of ancient proteins became truly feasible. Technological gains over the past 20 years have allowed increasing opportunities to better understand preservation, degradation, and recovery of the rich bioarchive of ancient proteins found in the archaeological and paleontological records. Growing from a handful of studies in the 1990s on individual highly abundant ancient proteins, paleoproteomics today is an expanding field with diverse applications ranging from the taxonomic identification of highly fragmented bones and shells and the phylogenetic resolution of extinct species to the exploration of past cuisines from dental calculus and pottery food crusts and the characterization of past diseases. More broadly, these studies have opened new doors in understanding past human-animal interactions, the reconstruction of past environments and environmental changes, the expansion of the hominin fossil record through large scale screening of nondiagnostic bone fragments, and the phylogenetic resolution of the vertebrate fossil record. Even with these advances, much of the ancient proteomic record still remains unexplored. Here we provide an overview of the history of the field, a summary of the major methods and applications currently in use, and a critical evaluation of current challenges. We conclude by looking to the future, for which innovative solutions and emerging technology will play an important role in enabling us to access the still unexplored "dark" proteome, allowing for a fuller understanding of the role ancient proteins can play in the interpretation of the past.

Proteomics and metabolomics composition of the ink of a letter in a fragment of a Dead Sea Scroll from Cave 11 (P1032-Fr0). J Proteomics 2021; 249:104370. [PMID: 34517122 DOI: 10.1016/j.jprot.2021.104370] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2021] [Accepted: 08/31/2021] [Indexed: 11/19/2022]
Abstract
It is well established that the ink pigment used for writing the Dead Sea Scrolls (DSS) is mainly composed of carbon soot. The ink's binder however has yet to be securely identified. By applying EVA (ethylene vinyl acetate containing strong anion and cation exchangers admixed with C8 and C18) diskettes on one fragment and analyzing the captured material, the following study was able to determine the composition of the binder. Proteins admixed of plant proteins (ribulose biphosphate carboxylase, rhamnogalacturonate lyase, α-galactosidase A, calmodulin, among those identified) as well as of a few glycoproteins with different combinations of pentosyl and hexosyl units with plant acids (stearic, palmitic, oleic, linoleic and linolenic acids) and terpenes (triacontanol, catechin, lupeol) are mixed attributes of acacia trees which suggests the use of gum Arabic as the ink's binder. SIGNIFICANCE: Whereas a huge body of reports has explored any possible aspect of the Dead Sea Scrolls, including the dating and the animal origin of the parchment, one aspect had not been investigated so far, namely which kind of ligand had been adopted to ensure a firm binding of the ink (in reality carbon soot) to the supporting parchment. In the present investigation it has been demonstrated that this "glue" is a mixture of plant proteins, as well as a few glycoproteins, together with plant acids and terpenes. These proteins and metabolites belong to two species of trees, Vachellia nilotica and Acacia Albida, widespread in this Middle East region. The EVA methodology here adopted has shown that it is possible to explore any item pertaining to the world Cultural Heritage in the absence of damage or contamination thus permititng to analyze any possible precious document stored in museum, public libraries and private collections.

Abstract
After a decade of experimental applications, it is the objective of this review to make a point on combinatorial peptide ligand libraries dedicated to low-abundance proteins from animals to plants and to microorganism proteomics. It is, thus, at the light of the recent technical developments and applications that we will examine the state of the art, its usage within the scientific community, and its openness to unexplored fields. The improvements of the methodology and its implementation in connection with analytical determinations of combinatorial peptide ligand library (CPLL)-treated samples are extensively reviewed and commented upon. Relevant examples covering few critical aspects describe the performance of the technology. Finally, a reflection on the technological future is attempted in particular by involving new concepts adapted to the limited availability of certain biological samples.

Abstract
During the last decade, paleoproteomics allowed us to open a direct window into the biological past, improving our understanding of the phylogenetic relationships of extant and extinct species, past human diseases, and reconstruction of the human diet. In particular, meta-proteomic studies, mainly carried out on ancient human dental calculus, provided insights into past oral microbial communities and ancient diets. On the contrary, very few investigations regard the analysis of ancient gut microbiota, which may enable a greater understanding of how microorganisms and their hosts have co-evolved and spread under the influence of changing diet practices and habitat. In this respect, this paper reports the results of the first-ever meta-proteomic analysis carried out on a gut tissue sample some 40,000 years old. Proteins were extracted by applying EVA (ethylene–vinyl acetate) films to the surface of the gut sample of a woolly mammoth (Mammuthus primigenus), discovered in 1972 close to the Shandrin River (Yakutia, Russia), and then investigated via a shotgun MS-based approach. Proteomic and peptidomic analysis allowed in-depth exploration of its meta-proteome composition. The results were validated through the level of deamidation and other diagenetic chemical modifications of the sample peptides, which were used to discriminate the “original” endogenous peptides from contaminant ones. Overall, the results of the meta-proteomic analysis here reported agreeing with the previous paleobotanical studies and with the reconstructed habitat of the Shandrin mammoth and provided insight into its diet. The data have been deposited to the ProteomeXchange with identifier < PXD025518 > .
