Toxins (Basel) 2022; 14:toxins14040288.

Abstract
Epsilon toxin (Etx) from Clostridium perfringens is the third most potent toxin after the botulinum and tetanus toxins. Etx is the main agent of enterotoxemia in ruminants and is produced by Clostridium perfringens toxinotypes B and D, causing great economic losses. Etx selectively binds to target cells, oligomerizes and inserts into the plasma membrane, and forms pores. A series of mutants have been previously generated to understand the cellular and molecular mechanisms of the toxin and to obtain valid molecular tools for effective vaccination protocols. Here, two new non-toxic Etx mutants were generated by selective deletions in the binding (Etx-ΔS188-F196) or insertion (Etx-ΔV108-F135) domains of the toxin. As expected, our results showed that Etx-ΔS188-F196 did not exhibit the usual Etx binding pattern but surprisingly recognized specifically an O-glycoprotein present in the proximal tubules of the kidneys in a wide range of animals, including ruminants. Although diminished, Etx-ΔV108-F135 maintained the capacity for binding and even oligomerization, indicating that the mutation particularly affected the pore-forming ability of the toxin.

Abstract
Lectins or clusters of carbohydrate-binding proteins of non-immune origin are distributed chiefly in the Plantae. Lectins have potent anti-infectivity properties for several RNA viruses including SARS-CoV-2. The primary purpose of this review is to review the ability of lectins mediated potential biotherapeutic and bioprophylactic strategy against coronavirus causing COVID-19. Lectins have binding affinity to the glycans of SARS-COV-2 Spike glycoprotein that has N-glycosylation sites. Apart from this, the complement lectin pathway is a "first line host defense" against the viral infection that is activated by mannose-binding lectins. Mannose-binding lectins deficiency in serum influences innate immunity of the host and facilitates infectious diseases including COVID-19. Our accumulated evidence obtained from scientific databases particularly PubMed and Google Scholar databases indicate that mannose-specific/mannose-binding lectins (MBL) have potent efficacies like anti-infectivity, complement cascade induction, immunoadjuvants, DC-SIGN antagonists, or glycomimetic approach, which can prove useful in the strategy of COVID-19 combat along with the glycobiological aspects of SARS-CoV-2 infections and antiviral immunity. For example, plant-derived mannose-specific lectins BanLac, FRIL, Lentil, and GRFT from red algae can inhibit and neutralize SARS-CoV-2 infectivity, as confirmed with in-vitro, in-vivo, and in-silico assessments. Furthermore, Bangladesh has a noteworthy resource of antiviral medicinal plants as well as plant lectins. Intensifying research on the antiviral plant lectins, adopting a glyco-biotechnological approach, and with deeper insights into the "glycovirological" aspects may result in the designing of alternative and potent blueprints against the 21st century's biological pandemic of SARS-CoV-2 causing COVID-19.

Localization of synthetic glycolipids in the cell and the dynamics of their insertion/loss. BIOCHIMICA ET BIOPHYSICA ACTA-BIOMEMBRANES 2021; 1863:183645. [PMID: 34019901 DOI: 10.1016/j.bbamem.2021.183645] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 12/30/2020] [Revised: 04/14/2021] [Accepted: 04/16/2021] [Indexed: 12/25/2022]
Abstract
Modification of the cell surface with synthetic glycolipids opens up a wide range of possibilities for studying the function of glycolipids. Synthetic glycolipids called Function-Spacer-Lipids (FSL; where F is a glycan or label, S is a spacer, and L is dioleoylphosphatidyl ethanolamine) easily and controllably modify the membrane of a living cells. This current study investigates the dynamics and mechanism of the FSL insertion and release/loss. FSL insert into the cell membrane (~1 million molecules per cell) within tens of minutes, almost regardless of the nature of the cells (including the thickness of their glycocalyx) and the size of the FSL glycan. FSLs do not accumulate uniformly, but instead form patches >300 nm in size either entrapped in the glycocalyx, or integrated in the plane of the plasma membrane, but always outside the cell rafts. The natural release (loss) of FSL from the modified cell was two orders of magnitude slower than attachment/insertion and occurred mainly in the form of released microvesicles with a size of 140 ± 5 nm. The accumulation of FSL as patches in the cell membrane is similar to the coalescence of natural glycosphingolipids and supports (along with their long residence time in the membrane) the use of FSL as probes for the study of glycosphingolipid-protein interactions.

Abstract
An efficient purification of recombinant proteins often requires a high ratio of recombinant to host proteins. In plants, Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) is the most abundant leaf protein, thus strongly impacting purification yield. Here, we describe a simple and robust purification procedure for recombinant proteins based on a differential precipitation of RuBisCO. In this context, four Legume lectin domains of Arabidopsis thaliana which belong to receptor-like kinases and cell wall proteins were produced from Nicotiana benthamiana leaves. The recombinant proteins exhibit a unique lectin domain consisting of around 250 amino acid residues with several predicted N-glycosylation sites and a six His-tag at the N-terminus. After ammonium sulphate precipitation of total soluble proteins, depletion of RuBisCO was obtained using citrate and succinate buffers during the salting-in step: this depletion was pH-dependent and the presence of di- or tri-carboxylic acids was required. The depleted protein extracts were then subjected to two chromatographic steps which were used in the negative mode to submit a protein fraction enriched as much as possible in recombinant lectin domains to a third chromatographic step (immobilized metal-ion chromatography). Three of the Legume lectin domains were purified near to homogeneity and revealed multiple N-glycosylation isoforms, particularly those from receptor-like kinases, which were characterised using specific lectins and deglycosylation enzymes. The production and purification of recombinant lectin domains will facilitate their biochemical characterisation in the context of cell-to-cell signalling and cell wall organisation.

Abstract
Datura stramonium seeds contain at least three chitin-binding isolectins as homo- or heterodimers of A and B subunits. This lectin has been used for the detection and isolation of sugar chains with N-acetyllactosaminyl structures on highly branched N-glycans. In terms of future diagnostic use, the development of a recombinant lectin will be the most effective approach for producing homogeneous lectin preparations. This chapter presents details of the procedure used for lectin purification and also describes a method that can be used for producing active recombinant homodimeric BB-isolectin in Arabidopsis plants.

Abstract
BACKGROUND Along with the rapid development of glycomic tools, the study of lectin-carbohydrate interactions has expanded, opening the way for applications in the fields of analytic, diagnostic, and drug delivery. Chitin-binding lectins (CBLs) play roles in immune defense against chitin-containing pathogens. CBLs from species of the Solanaceae family, such as tomato, potato and jimsonweed, display different binding specificities to sugar chains containing poly-N-acetyllactosamine. RESULTS In this report, CBLs from Solanum integrifolium were isolated by ion exchange chromatography. The fractions showed hemagglutination activity (HA). The recombinant CBL in the 293F cell culture supernatant was able to inhibit the growth of Rhizoctonia solani and Colletotrichum gloeosporioide. Furthermore, the carbohydrate-binding property of CBLs was confirmed with the inhibition of HA. Binding of CBL to Spodoptera frugiperda (sf21) insect cells can partly be inhibited by N-Acetylglucosamine (GlcNAc), which is related to decrease mitochondrial membrane potential of sf21 cells. CONCLUSIONS The results showed that CBL exhibited antifungal properties and inhibited insect cell growth, which is directly correlated to the lectin-carbohydrate interaction. Further identification and characterization of CBLs will help to broaden their scope of application in plant defense and in biomedical applications.

Sugar-Binding Profiles of Chitin-Binding Lectins from the Hevein Family: A Comprehensive Study. Int J Mol Sci 2017; 18:ijms18061160.

Abstract
Chitin-binding lectins form the hevein family in plants, which are defined by the presence of single or multiple structurally conserved GlcNAc (N-acetylglucosamine)-binding domains. Although they have been used as probes for chito-oligosaccharides, their detailed specificities remain to be investigated. In this study, we analyzed six chitin-binding lectins, DSA, LEL, PWM, STL, UDA, and WGA, by quantitative frontal affinity chromatography. Some novel features were evident: WGA showed almost comparable affinity for pyridylaminated chitotriose and chitotetraose, while LEL and UDA showed much weaker affinity, and DSA, PWM, and STL had no substantial affinity for the former. WGA showed selective affinity for hybrid-type N-glycans harboring a bisecting GlcNAc residue. UDA showed extensive binding to high-mannose type N-glycans, with affinity increasing with the number of Man residues. DSA showed the highest affinity for highly branched N-glycans consisting of type II LacNAc (N-acetyllactosamine). Further, multivalent features of these lectins were investigated by using glycoconjugate and lectin microarrays. The lectins showed substantial binding to immobilized LacNAc as well as chito-oligosaccharides, although the extents to which they bound varied among them. WGA showed strong binding to heavily sialylated glycoproteins. The above observations will help interpret lectin-glycoprotein interactions in histochemical studies and glyco-biomarker investigations.
