1. Heparin, sulfated heparinoids, and lipoteichoic acids bind to the 70-kDa peptidoglycan/lipopolysaccharide receptor protein on lymphocytes
R Dziarski, D Gupta J Biol Chem. 1994 Jan 21;269(3):2100-10.
The same 70-kDa protein, present on the surface of mouse lymphocytes, served as the predominant binding site for heparin, heparinoids, and bacterial lipoteichoic acids, as well as peptidoglycan and lipopolysaccharides. This conclusion was supported by the following results: (a) all of these compounds photoaffinity cross-linked to one major 70-kDa 6.5-7.0 pI protein that co-migrated on two-dimensional polyacrylamide gel electrophoresis; (b) peptide maps of the 70-kDa proteins digested with chymotrypsin, subtilisin, protease V, or papain yielded the same peptides for heparin-, lipoteichoic acid-, peptidoglycan-, and lipopolysaccharide-binding proteins; (c) cross-linking of peptidoglycan, lipopolysaccharide, lipoteichoic acid, and heparin was competitively inhibited by the same compounds with the same order of potency, i.e. carboxyl-reduced sulfated heparin > peptidoglycan > pentosan polysulfate > heparin > chitin > dextran sulfate > trestatin sulfate > polyanetholesulfonate > fucoidan > beta-cyclodextrin tetradecasulfate > heparan sulfate > carrageenan lambda > lipoteichoic acids > Re-lipopolysaccharide > lipopolysaccharide > lipid A > polygalacturonic acid; and (d) cross-linking of each of these ligands was not inhibited by carboxyl-reduced heparin, dextran, beta-cyclodextrin, trestatin, carrageenan kappa, chondroitin 4-sulfate, chondroitin 6-sulfate, beta-D-glucan, carboxy-methylcellulose, levan, alpha-D-mannan, and glycogen. The minimum size of the molecule that bound was 7-9 glycan residues, whereas, di- and trisaccharides did not bind. There was a logarithmic linear relationship between the strength of the binding and the length of the polymer (up to > 1500 glycan residues), which indicates an avidity effect of the cooperative binding of one polymeric molecule to several receptor molecules on the cell surface. The 70-kDa receptor, therefore, has a broad, but limited specificity of binding for non-charged (peptidoglycan and chitin), highly negatively charged (heparin and heparinoids), and weakly negatively charged (lipoteichoic acids, lipopolysaccharides, and lipid A) ligands.
2. Acarbose May Function as a Competitive Exclusion Agent for the Producing Bacteria
Samuel Tanoeyadi, Takeshi Tsunoda, Takuya Ito, Benjamin Philmus, Taifo Mahmud ACS Chem Biol. 2023 Feb 17;18(2):367-376. doi: 10.1021/acschembio.2c00795. Epub 2023 Jan 17.
Acarbose is a well-known microbial specialized metabolite used clinically to treat type 2 diabetes. This natural pseudo-oligosaccharide (PsOS) shows potent inhibitory activity toward various glycosyl hydrolases, including α-glucosidases and α-amylases. While acarbose and other PsOSs are produced by many different bacteria, their ecological or biological role in microbial communities is still an open question. Here, we show that several PsOS-producing actinobacteria, i.e., Actinoplanes sp. SE50/110 (acarbose producer), Streptomyces glaucescens GLA.O (acarbose producer), and Streptomyces dimorphogenes ATCC 31484 (trestatin producer), can grow in the presence of acarbose, while the growth of the non-PsOS-producing organism Streptomyces coelicolor M1152 was suppressed when starch is the main source of energy. Further investigations using recombinant α-amylases from S. coelicolor M1152 and the PsOS-producing actinobacteria revealed that the S. coelicolor α-amylase was inhibited by acarbose, whereas those from the PsOS-producing bacteria were not inhibited by acarbose. Bioinformatic and protein modeling studies suggested that a point mutation in the α-amylases of the PsOS-producing actinobacteria is responsible for the resistance of those enzymes toward acarbose. Converting the acarbose-resistant α-amylase AcbE to its A304H variant diminished its acarbose-resistance property. Taken together, the results suggest that acarbose is used by the producing bacteria as a competitive exclusion agent to suppress the growth of other microorganisms in their natural environment, while the producing organisms equip themselves with α-amylase variants that are resistant to acarbose.
3. Inhibition of selectin-mediated cell adhesion and prevention of acute inflammation by nonanticoagulant sulfated saccharides. Studies with carboxyl-reduced and sulfated heparin and with trestatin a sulfate
X Xie, A S Rivier, A Zakrzewicz, M Bernimoulin, X L Zeng, H P Wessel, M Schapira, O Spertini J Biol Chem. 2000 Nov 3;275(44):34818-25. doi: 10.1074/jbc.M001257200.
Selectins play a major role in the inflammatory reaction by initiating neutrophil attachment to activated vascular endothelium. Some heparin preparations can interact with L- and P-selectin; however, the determinants required for inhibiting selectin-mediated cell adhesion have not yet been characterized. We now report that carboxyl-reduced and sulfated heparin (prepared by chemical modifications of porcine intestinal mucosal heparin leading to the replacement of carboxylates by O-sulfate groups) and trestatin A sulfate (obtained by sulfation of trestatin A, a non-uronic pseudo-nonasaccharide extracted from Streptomyces dimorphogenes) exhibit strong anti-P-selectin and anti-L-selectin activity while lacking antithrombin-mediated anticoagulant activity. In vitro experiments revealed that both compounds inhibited P-selectin- and L-selectin-mediated cell adhesion under laminar flow conditions. Moreover, carboxyl-reduced and sulfated heparin and trestatin A sulfate were also active in vivo, as assessed by experiments showing 1) that microinfusion of trestatin A sulfate reduced by 96% leukocyte rolling along rat mesenteric postcapillary venules and 2) that both compounds inhibited (by 58-81%) neutrophil migration into thioglycollate-inflamed peritoneum of BALB/c mice. These results indicate that nonanticoagulant sulfated saccharides targeted at P-selectin and L-selectin may have therapeutic potential in inflammatory disorders.
