beta-N-Acetylhexosaminidase (EC 3.2.1.52) was purified from the culture filtrate of Pycnoporus cinnabarinus to homogeneity by polyacrylamide disc gel electrophoresis.The ratio of beta-GlcNAcase activity to beta-GalNAcase activity remained constant during the purification process.The molecular weight of this enzyme was estimated to be about 120,000 by gel filtration, and the isoelectric point was at about pH 5.4.The optimum pH was at 2.2 for pNPGlcNAc and around 3.7 for pNPGalNAc.The enzyme was relatively stable at acid pH range of 2-4 (for 45 hr at 5 deg C) and below 45 deg C (for 10 min at pH 2.8).The enzyme hydrolysed chito-oligosaccharides, such as N,N-diacetylchitobiose, N,N,N-triacetylchitotriose and N,N,N,N-tetraacetylchitotetraose.

A highly convergent strategy for the synthesis of several derivatives of the lipid A of Rhizobium sin-1 has been developed. The synthetic derivatives are 2-aminogluconate 3 and 2-aminogluconolactone 4, both of which lack C-3 acylation. These derivatives were obtained by the preparation of disaccharides in which the two amino groups and the C-3? hydroxy group could be modified individually with acyl or beta-hydroxy fatty acyl groups. Detailed NMR spectroscopy and MS analysis of 3 and 4 revealed that, even under neutral conditions, the two compounds equilibrate. The synthetic compounds lack the proinflammatory effects of Escherichia coli lipopolysaccharide (LPS), as indicated by an absence of tumor necrosis factor production. Although 3 and 4 were able to antagonize E. coli LPS, they were significantly less potent than the synthetic compound 2, which is acylated at C-3, and R. sin-1 LPS; these results indicate that the beta-hydroxy fatty acyl group at C-3 contributes to the antagonistic properties of R. sin-1 LPS. Based on a comparison of the biological responses of the synthetic lipid A derivatives with those of the R. sin-1 LPS and lipid A, the 3-deoxy-D-manno-octulosonic moieties appear to be important for the optimal antagonization of enteric LPS-induced cytokine production.

A versatile green gelator suitable for multiple applications is reported. Gelation of organic solvents in a significantly low gelation time (<5 s) is achieved. The effect of cooling and sonication on gelation time is investigated. Apart from organic solvents, the gelator is capable of forming gels with fuel oils such as diesel and petrol also; therefore, it has been utilized for the separation of oil from an oil/water mixture through selective gelation of the oil. The gelator was also found to be capable of forming hydrogels through rational control of the reaction conditions. Hydrogel prepared using the gelator was further explored as reaction medium for the growth of gold nanoparticles. In the case of nanoparticle synthesis, the gelator served not only as a capping agent but also as a reducing agent. By taking advantage of the dual functionality of the gelator (capping and reducing agent), nanoparticles of both gold and silver were prepared in fluid medium also. The organogel, prepared using toluene and gelator, was utilized for the removal of the waterborne synthetic dye rhodamine B.

Fischer glycosylation has been used for decades for the synthesis of simple alkyl and aryl glycosides from free sugars. The reaction proceeds under reflux in the presence of catalytic acid with the alcohol as solvent. The main deficiency of this reaction is the long reaction time required. In this study microwave heating has been utilised for the Fischer glycosylation reaction of N-acetyl-d-glucosamine, N-acetyl-d-galactosamine, d-glucose, d-galactose and d-mannose with a variety of alcohols (methanol, ethanol, benzyl alcohol and allyl alcohol). Remarkable acceleration of the glycosylation reactions (minutes compared to hours) over conventional reflux heating was observed with good yields and production of the alpha-glycoside as the dominant product.

Uridine diphosphate N-acetyl muramic acid (UDP NAM) is a critical intermediate in bacterial peptidoglycan (PG) biosynthesis. As the primary source of muramic acid that shapes the PG backbone, modifications installed at the UDP NAM intermediate can be used to selectively tag and manipulate this polymer via metabolic incorporation. However, synthetic and purification strategies to access large quantities of these PG building blocks, as well as their derivatives, are challenging. A robust chemoenzymatic synthesis was developed using an expanded NAM library to produce a variety of 2-N-functionalized UDP NAMs. In addition, a synthetic strategy to access bio-orthogonal 3-lactic acid NAM derivatives was developed. The chemoenzymatic UDP synthesis revealed that the bacterial cell wall recycling enzymes MurNAc/GlcNAc anomeric kinase (AmgK) and NAM alpha-1 phosphate uridylyl transferase (MurU) were permissive to permutations at the two and three positions of the sugar donor. We further explored the utility of these derivatives in the fluorescent labeling of both Gram (-) and Gram (+) PG in whole cells using a variety of bio-orthogonal chemistries including the tetrazine ligation. This report allows for rapid and scalable access to a variety of functionalized NAMs and UDP NAMs, which now can be used in tandem with other complementary bio-orthogonal labeling strategies to address fundamental questions surrounding PG’s role in immunology and microbiology.

The amino acid sequence of satyr tragopan lysozyme and its activity was analyzed. Carboxymethylated lysozyme was digested with trypsin and the resulting peptides were sequenced. The established amino acid sequence had three amino acid substitutions at positions 103 (Asn to Ser), 106 (Ser to Asn), and 121 (His to Gln) comparing with Temminck’s tragopan lysozyme and five amino acid substitutions at positions 3 (Phe to Tyr), 15 (His to Leu), 41 (Gln to His), 101 (Asp to Gly) and 103 (Asn to Ser) with chicken lysozyme. The time course analysis using N-acetylglucosamine pentamer as a substrate showed a decrease of binding free energy change, 1.1 kcal/mol at subsite A and 0.2 kcal/mol at subsite B, between satyr tragopan and chicken lysozymes. This was assumed to be responsible for the amino acid substitutions at subsite A-B at position 101 (Asp to Gly), however another substitution at position 103 (Asn to Ser) considered not to affect the change of the substrate binding affinity by the observation of identical time course of satyr tragopan lysozyme with turkey and Temminck’s tragopan lysozymes that carried the identical amino acids with chicken lysozyme at this position. These results indicate that the observed decrease of binding free energy change at subsites A-B of satyr tragopan lysozyme was responsible for the amino acid substitution at position 101 (Asp to Gly).

Abstract Herein, we report on a highly efficient synthesis of a crystalline protected LewisX trisaccharide that was converted to LewisX following global deprotection. The trisaccharide was prepared in a highly convergent synthesis (seven steps, longest linear sequence) and in a 38% overall yield using a strategy that involved the regioselective glycosylation of a GlcNAc acceptor with a galactose thioglycoside donor, followed by fucosylation of the remaining free GlcNAc hydroxyl as key steps. The core trisaccharide also has the potential to be converted to other members of the Type-2 Lewis family of antigens due to the orthogonal nature of the protecting groups employed.
