A novel exochitinase gene (Echi47) was directly cloned from the pig fecal environment DNA using the genomic walking PCR technique and expressed in Escherichia coli BL21 (DE3). Echi47 has an open reading frame (ORF) of 1,161 bp encoding 386 amino acids. The amino acid sequence of Echi47 showed 36% identity with that of chitinase from Coprinellus congregatus. The recombinant exochitinase was purified with specific activity toward colloidal chitin of 6.84 U/mg. Echi47 was optimally active at pH 5.0 and 40 C, respectively. When colloidal chitin was used as substrate, N-acetylchitobiose [(GlcNAc)2] was mostly produced at the initial stage, suggesting that it is an exochitinase. Echi47 exhibited excellent resistance to pepsin, trypsin, proteinase K, and flavor protease. Under simulated alimentary tract conditions, Echi47 was stable and active, releasing 21.1 mg of N-acetylchitooligosaccharides from 80 mg of colloidal chitin. These properties make Echi47 a potential additive in the food and feed industries.

N-Acetyl glucosamine and chitooligosaccharides are selectively converted into beta-glycosides without protection of the other hydroxyl groups by alkylation of the anomeric alkoxides in N,N-dimethylformamide containing lithium bromide. Addition of the lithium salt notably improves the stereoselectivity of the glycosylation of the monomer and the efficiency of the process with higher oligomers.

The syntheses of methyl 2,3-diamino-4,6-O-benzylidene-2,3-dideoxy-alpha-d-hexopyranosides of glucose, mannose, gulose, and talose and methyl 2-amino-4,6-benzylidene-2,3-dideoxy-3-tosylamido-alpha-d-glucopyranoside are exhaustively presented, as well as their application as ligands in half-sandwich ruthenium(II), rhodium(III), and iridium(III) complexes. The complex formation occurs highly diastereoselectively, creating a stereogenic metal center. The molecular structures of the ligands and their complexes were investigated by X-ray structure analysis, NMR spectroscopy, polarimetry, and DFT methods. The diamino monosaccharide complexes have been subjected to antitumor activity studies. In vitro tests of a few ruthenium complexes against different cancer cell types showed antiproliferative activities 4-10 times lower than that of cisplatin.

A facile and practical protocol was developed for the synthesis of glycosyl iodides using AlI3 generated in situ from cheap aluminum metal and molecular iodine. Furthermore, in combination with iodine-catalyzed per-O-acetylation, sequential synthesis of per-acetylated glycosyl iodides, per-acetylated thioglycosides, selenoglycoside, and O-glycosides from unprotected reducing sugars was also achieved with complete diastereocontrol in a one-pot version.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide, molecular formula is C8H15NO6.

A general method for the stereoselective coupling of unprotected oligosaccharides with any substrate containing a N,O-disubstituted hydroxylamine group is described. The cyclic nature of the oligosaccharide reducing unit is preserved and the substrate glycosylated with high diastereoseletivity to sugar through an amino (N[OR2]-) or art aminoxy (N[R1]-O-) linkage. Due to the uniquely high chemical reactivity and specificity of disubstituted hydroxylamine toward the sugar reducing end, neither protecting groups nor activation methods are required to perform the reaction in aqueous solution. The characteristic features and the scope of this new type of glycosylation reaction are exemplified for the chemoselective synthesis of model glycopeptides.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 14215-68-0, you can also check out more blogs about14215-68-0

RegIII proteins are secreted C-type lectins that kill Gram-positive bacteria and play a vital role in antimicrobial protection of the mammalian gut. RegIII proteins bind their bacterial targets via interactions with cell wall peptidoglycan but lack the canonical sequences that support calcium-dependent carbohydrate binding in other C-type lectins. Here, we use NMR spectroscopy to determine the molecular basis for peptidoglycan recognition by HIP/PAP, a human RegIII lectin. We show that HIP/PAP recognizes the peptidoglycan carbohydrate backbone in a calcium-independent manner via a conserved “EPN” motif that is critical for bacterial killing. While EPN sequences govern calcium-dependent carbohydrate recognition in other C-type lectins, the unusual location and calcium-independent functionality of the HIP/PAP EPN motif suggest that this sequence is a versatile functional module that can support both calcium-dependent and calcium-independent carbohydrate binding. Further, we show HIP/PAP binding affinity for carbohydrate ligands depends on carbohydrate chain length, supporting a binding model in which HIP/PAP molecules “bind and jump” along the extended polysaccharide chains of peptidoglycan, reducing dissociation rates and increasing binding affinity. We propose that dynamic recognition of highly clustered carbohydrate epitopes in native peptidoglycan is an essential mechanism governing high-affinity interactions between HIP/PAP and the bacterial cell wall.

The use of ionic liquids as alternative solvents for enzyme catalysis was investigated. beta-Galactosidase from Bacillus circulans catalyses the synthesis of N-acetyllactosamine starting from lactose and N-acetylglucosamine in a transglycoslyation reaction. The addition of 25% v/v of 1,3-di-methyl-imidazol-methyl sulfate [MMIM] [MeSO4] as a water-miscible ionic liquid suppresses the secondary hydrolysis of the formed product, resulting in doubling the yield to almost 60%. The enzyme can be reused several times after ultrafiltration of the reaction mixture without loss of activity. Results of different amounts of ionic liquids in the reaction medium on the thermostability of the galactosidase as well as on oxidoreductases are presented as well.
