Abstract
In the present study, lotus seed oligosaccharides (LOSs) were isolated from lotus (Nelumbo nucifera Gaertn.) seeds using preparative liquid chromatography. LOS structures were characterized using fourier transform infrared spectroscopy (FT-IR), acid hydrolysis, tandemmass spectrometry (MS/MS) and 1D/2D nuclear magnetic resonance (NMR) spectroscopy. Then, Lactobacillus acidophilus was used to evaluate the prebiotic activity of LOSs in vitro. The structural analysis revealed that the monosaccharide components of LOSs included glucose, mannose, fructose and galactose. The MS/MS results indicated that disaccharides, trisaccharides, trisaccharides and tetrasaccharides were the constituents of isolated oligosaccharide polymers LOS2, LOS3-1, LOS3-2, and LOS4, respectively. The FT-IR and 1D/2D NMR data confirmed that LOS3 and LOS4 had a linear structure consisting of (1 → 6)-α-d-mannopyranosyl and glucopyranosyl residues. LOS3-1 and LOS4 effectively and selectively promoted the growth of an L. acidophilus strain, according to the results of the assays of optical density and the short-chain fatty acid (SCFA) content in the culture broth.

Abstract
A β-galactoside α2,6-sialyltransferase (ST) from the marine bacterium Photobacterium sp. JT-ISH-224 with a broad acceptor substrate specificity was fused to a fungal biotin-binding protein tamavidin 2 (TM2) to produce immobilized enzyme. Specifically, a gene for the fusion protein, in which ST from Photobacterium sp. JT-ISH-224 and TM2 were connected via a peptide linker (ST-L-TM2) was constructed and expressed in Escherichia coli. The ST-L-TM2 was produced in the soluble form with a yield of approximately 15,000 unit/300 ml of the E. coli culture. The ST-L-TM2 was partially purified and part of it was immobilized onto biotin-bearing magnetic microbeads. The immobilized ST-L-TM2 onto microbeads could be used at least seven consecutive reaction cycles with no observed decrease in enzymatic activity. In addition, the optimum pH and temperature of the immobilized enzyme were changed compared to those of a free form of the ST. Considering these results, it was strongly expected that the immobilized ST-L-TM2 was a promising tool for the production of various kind of sialoligosaccharides.

Abstract
The structural diversity of glycoproteins often comes from post-translational glycosylation with heterogeneous N-glycans. Understanding the complexity of glycans related to various biochemical processes demands a well-defined synthetic sugar library. We report herein a unified convergent strategy for the rapid production of bi-, tri-, and tetra-antennary complex type N-glycans with and without terminal N-acetylneuraminic acid residues connected via the α-2,6 or α-2,3 linkages. Moreover, using sialyltransferases to install sialic acid can minimize synthetic steps through the use of shared intermediates to simplify the complicated procedures associated with conventional sialic acid chemistry. Furthermore, these synthetic complex oligosaccharides were compiled to create a glycan array for the profiling of HIV-1 broadly neutralizing antibodies PG9 and PG16 that were isolated from HIV infected donors. From the study of antibody PG16, we identified potential natural and unnatural glycan ligands, which may facilitate the design of carbohydrate-based immunogens and hasten the HIV vaccine development.

Abstract
Enzymatic synthesis of oligosaccharides using specific sialyltransferases enables single-step glycosylation with high positional and anomeric structural selectivity. The α2,3-sialyltransferase cloned from the marine bacterium Photobacterium sp. JT-ISH-224 has unique and broad acceptor specificity, but this enzyme possesses not only sialyltransferase activity but also sialidase activity. To synthesize sialoside derivative effectively, only sialyltransferase activity is required. We report here that addition of organic solvents was effective to control the sialidase activity and a resulting product was not hydrolyzed. The enzyme was even active in the presence of acetonitrile, ethanol, methanol, or acetone. To determine the suitable concentrations of these organic solvents, only sialyltransferase activity could be allowed, and as a result, the stable synthesis of sialoside could be achieved.

Abstract
Glycosyltransferases are useful synthetic tools for the preparation of natural oligosaccharides, glycoconjugates and their analogues. High expression levels of recombinant enzymes have allowed their use in multi-step reactions, on mg to multi-gram scales. Since glycosyltransferases are tolerant with respect to utilizing modified donors and acceptor substrates they can be used to prepare oligosaccharide analogues and for diversification of natural products. New sources of enzymes are continually discovered as genomes are sequenced and they are annotated in the Carbohydrate Active Enzyme (CAZy) glycosyltransferase database. Glycosyltransferase mutagenesis, domain swapping and metabolic pathway engineering to change reaction specificity and product diversification are increasingly successful due to advances in structure-function studies and high throughput screening methods.

Abstract
Sialyltransferases transfer N-acetylneuraminic acid (Neu5Ac) from the common donor substrate of these enzymes, cytidine 5′-monophospho-N-acetylneuraminic acid (CMP-Neu5Ac), to acceptor substrates. The enzymatic reaction products including sialyl-glycoproteins, sialyl-glycolipids and sialyl-oligosaccharides are important molecules in various biological and physiological processes, such as cell-cell recognition, cancer metastasis, and virus infection. Thus, sialyltransferases are thought to be important enzymes in the field of glycobiology. To date, many sialyltransferases and the genes encoding them have been obtained from various sources including mammalian, bacterial and viral sources. During the course of our research, we have detected over 20 bacteria that produce sialyltransferases. Many of the bacteria we isolated from marine environments are classified in the genus Photobacterium or the closely related genus Vibrio. The paper reviews the sialyltransferases obtained mainly from marine bacteria.

Abstract
We confirmed that a recombinant α-(2→3)-sialyltransferase cloned from Photobacterium sp. JT-ISH-224 recognizes inositols having a structure corresponding to the C-3 and C-4 of a galactopyranoside moiety, such as epi-, 1d-chiro, myo-, and muco-inositol, as acceptor substrates, and that the enzyme can transfer N-acetylneuraminic acid (Neu5Ac) from cytidine 5'-monophospho-N-acetylneuraminic acid (CMP-Neu5Ac) to them. After purifying the reaction products, the structures were confirmed by use of NMR spectroscopy and mass spectrometry. From these results, it was clearly shown that the α-(2→3)-sialyltransferase from Photobacterium sp. JT-ISH-224 recognizes acceptor substrates through the cis-diol structure corresponding to the 3- and 4-position of the galactopyranoside moiety.
