Abstract
Abstract
The glycoconjugates, herein glyco-proteins, existing in animal skins are closely related to the effectiveness of unhairing and fiber opening-up. Glycosidases have been used in leather making processes to reduce pollutants and improve leather quality. But the selection of glycosidases is still blind because the related mechanisms are not well understood yet. Hence, the animal skin structures and glycoconjugates components, the advances in the methods and mechanisms of removing glycoconjugates related to unhairing and fiber opening-up in leather manufacture, the kinds, compositions, structures and functions of typical glycoconjugates in skin are summarized. Then the approaches to destroy them, possible glycosidases suitable for leather making and their acting sites are analyzed based on the recognition of glycoconjugates in skin and the specificities of glycosidases toward substrates. It is expected to provide useful information for the optimization of glycosidases and the development of new enzymes and the cleaner technologies of unhairing and opening up fiber bundles assisted by glycosidases.

Abstract
After generating much interest in the past as an aid in solving structural problems for complex molecules such as polysaccharides, carbohydrate-hydrolyzing enzymes of marine origin still appear as interesting biocatalysts for a range of useful applications in strong interdisciplinary fields such as green chemistry and similar domains. The multifaceted fields in which these enzymes are of interest and the scarce number of original articles in literature prompted us to provide the specialized analysis here reported. General considerations from modern (2016-2017 interval time) review articles are at start of this manuscript; then it is subsequently organized in sections according to particular biopolymers and original research articles are discussed. Literature sources like the Science Direct database with an optimized W/in search, and the Espacenet patent database were used.

Abstract
A method for the synthesis of carbohydrate chains (glycosaminoglycans) and their coupling to peptides was investigated using proteoglycans. Glycosidases generally catalyze a hydrolytic reaction, but can also mediate the reverse reaction, which in this case is a transglycosylation. In the transglycosylation reaction of bovine testicular hyaluronidase, which is an endoglycosidase, glycosaminoglycans (hyaluronan and chondroitin sulfates) release disaccharide (uronic acid-N-acetylhexosamine) moieties from non-reducing terminal sites, and then the liberated disaccharides are transferred immediately to the non-reducing termini of other glycosaminoglycan chains. Using such continuous reactions, it is possible to synthesize glycosaminoglycan chains according to a specific design. It then becomes possible to transfer glycosaminoglycan chains synthesized on a peptide to other peptides using the transglycosylation reaction of endo-β-xylosidase acting on the linkage region between a peptide and glycosaminoglycan chains of proteoglycans. We believe this approach will open a new field for the synthesis of homogeneous proteoglycans or their corresponding analogues.

Abstract
The marine ecosystem can be considered a rather unexplored source of biological material (e.g. natural substances with therapeutic activity) and can also be a surprising source of enzymes carrying new and interesting catalytic activities to be applied in biocatalysis. The use of glycosyl hydrolases from marine environments dates back to the end of the 1960s and was mainly focused on the development of sensitive and reliable hydrolytic methods for the analysis of sugar chains. As a result not all the benefits of a particular enzymatic activity have been investigated, especially regarding the transglycosylation potential of these enzymes for the synthesis of glycosidic bonds. In this review, the potential of marine sources will be demonstrated reporting on the few examples found in literature for the synthesis and hydrolysis of biologically relevant oligosaccharides catalyzed by glycosyl hydrolases of marine origin. Particular emphasis is given to the synthesis of glycosidic bonds, which is easy by the use of glycosyl hydrolases. Further aspects considered in this review are applications of these biocatalysts for vegetal waste treatment in recovering useful materials, for structural identification and for preparation of target materials from new purified polysaccharides, for the synthesis or modification of food-related compounds and for glycobiology related studies.

Abstract
Novel chromogenic substrates for endo-beta-galactosidase were designed on the basis of the structural features of keratan sulfate. Galbeta1-4GlcNAcbeta1-3Galbeta1-4GlcNAcbeta-pNP (2), which consists of two repeating units of N-acetyllactosamine, was synthesized enzymatically by consecutive additions of GlcNAc and Gal residues to p-nitrophenyl beta-N-acetyllactosaminide. In a similar manner, GlcNAcbeta1-3Galbeta1-4GlcNAcbeta-pNP (1), GlcNAcbeta1-3Galbeta1-4Glcbeta-pNP (3), Galbeta1-4GlcNAcbeta1-3Galbeta1-4Glcbeta-pNP (4), Galbeta1-3GlcNAcbeta1-3Galbeta1-4Glcbeta-pNP (5), and Galbeta1-6GlcNAcbeta1-3Galbeta1-4Glcbeta-pNP (6) were synthesized as analogues of 2. Endo-beta-galactosidases released GlcNAcbeta-pNP or Glcbeta-pNP in an endo-manner from each substrate. A colorimetric assay for endo-beta-galactosidase was developed using the synthetic substrates on the basis of the determination of p-nitrophenol liberated from GlcNAcbeta-pNP or Glcbeta-pNP formed by the enzyme through a coupled reaction involving beta-N-acetylhexosaminidase (beta-NAHase) or beta-d-glucosidase. Kinetic analysis by this method showed that the value of Vmax/Km of 2 for Escherichia freundii endo-beta-galactosidase was 1.7-times higher than that for keratan sulfate, indicating that 2 is very suitable as a sensitive substrate for analytical use in an endo-beta-galactosidase assay. Compound 1 still acts as a fairly good substrate despite the absence of a Gal group in the terminal position. In addition, the hydrolytic action of the enzyme toward 2 was shown to be remarkably promoted compared to that of 4 by the presence of a 2-acetamide group adjacent to the p-nitrophenyl group. This was the same in the case of a comparison of 1 and 3. Furthermore, the enzyme also catalysed a transglycosylation on 1 and converted it into GlcNAcbeta1-3Galbeta1-4GlcNAcbeta1-3Galbeta1-4GlcNAcbeta-pNP (9) and GlcNAcbeta1-3Galbeta1-4GlcNAcbeta1-3Galbeta1-4GlcNAcbeta1-3Galbeta1-4GlcNAcbeta-pNP (10) as the major products, which have N-acetyllactosamine repeating units.

Abstract
Endo-beta-xylosidase from the mid-gut gland of the molluscus Patinopecten is an endo-type glycosidase that hydrolyzes the xylosyl serine linkage between a core protein and a glycosaminoglycan (GAG) chain, releasing the intact GAG chain from proteoglycan. In this study, we investigated GAG chain transfer activity of this enzyme, in order to develop a method for attaching GAG chains to peptide. Peptidochondroitin sulfate (molecular mass of sugar chain, 30 kDa) from bovine tracheal cartilage as a donor and butyloxycarbonyl-leucyl-seryl-threonyl-arginine-(4-methylcoumaryl-7-amide) as an acceptor were incubated with endo-beta-xylosidase. As a result, a reaction product with the same fluorescence as the acceptor peptide was observed. High pressure liquid chromatography analysis, cellulose acetate membrane electrophoresis, and enzymatic digestion showed that this reaction product had the chondroitin sulfate (ChS) from the donor. Furthermore, the acceptor peptide was released from this reaction product after hydrolysis by endo-beta-xylosidase. Therefore, it was confirmed that the ChS chain released from the donor was transferred to the acceptor peptide by the GAG chain transfer reaction of endo-beta-xylosidase. The optimal pH for hydrolysis by this enzyme was found to be about 4.0, whereas that for this reaction was about 3.0. Not only the ChS but also the dermatan sulfate and the heparan sulfate were transferred to the acceptor peptide by this reaction. By using this reaction, the GAG chain could be attached to the peptide in one step. The GAG chain transfer reaction of endo-beta-xylosidase should be a significant glycotechnological tool for the artificial synthesis of proteoglycan.

Abstract
Lactose is a principal carbohydrate in nearly all species of mammalian milk. In order to examine the acceptor substrate specificity of lactose synthase in vivo, D-xylose as an acceptor substrate was injected into the jugular vein of a Holstein cow during lactation, then a milk sample obtained by milking. beta1, beta1-galactopyranosyl xylopyranoside, a nonreducing disaccharide, was separated from the bovine milk sample after elimination of reducing sugars, identified by fast-atom bombardment (FAB)-MS and 1H-NMR analysis. A mixture of beta1,beta1- and beta1, 4-galactopyranosyl xylopyranoside fractions was also obtained by thin layer chromatography from the milk sample and elucidated by electrospray ionization (ESI)-MS and 1H NMR analysis. Comparison of the integrated intensity of the products shows that the beta1,beta1 and beta1,4 isomers are present in a ratio of 1.0 : 1.4, suggesting that D-xylose, transported from capillary blood across the plasma membrane of the mammary gland, was recognized by lactose synthase in its normal and reverse orientation owing to high symmetry of its structure. While the beta1,4-isomer is known as a fragment of the linkage region between the protein and the polysaccharide chain of proteoglycans, the beta1,beta1-isomer has not been identified in vivo. Here, we demonstrate that galactosylation of D-xylose transported from the capillary blood can occur by lactose synthase catalysis in the mammary gland while the usual galactosylation of D-glucose proceeds. In addition, these results suggest that the possibility of endogenous occurrence of the beta,beta-trehalose type disaccharide in the mammary gland of lactating mammals may not be ruled out.

Abstract
The reconstruction of glycosaminoglycan chains using the transglycosylation reaction of testicular hyaluronidase was investigated. First, the optimal conditions for the transglycosylation reaction catalyzed by the enzyme were determined by incubation with the enzyme, using hyaluronic acid (M(r) = 800,000) as a donor and pyridylaminated hyaluronic acid hexasaccharide having glucuronic acid at the nonreducing terminal as an acceptor. The carbohydrate chains as reaction products were determined by high performance liquid chromatography and mass spectrometry. The optimal pH for hydrolysis by the enzyme was found to be about 5.0, whereas that for the transglycosylation reaction was about 7.0. Sodium chloride in the reaction medium inhibited the transglycosylation reaction. Under the optimal conditions, the carbohydrate chains were sequentially transferred along with disaccharide units to the nonreducing terminal of the acceptor and elongated up to docosasaccharide from the acceptor, pyridylaminated hexasaccharide. Using a combination of hyaluronic acid, chondroitin, and chondroitin 4- and 6-sulfate as an acceptor and a donor, it was possible to reconstruct hybrid chains, which were natural or unnatural types of glycosaminoglycan chains. Therefore, it is highly likely that application of the transglycosylation reaction using testicular hyaluronidase would facilitate artificial reconstruction of glycosaminoglycans having some physiological functions.

Abstract
An assay method was devised for measuring the activity of galactosyltransferase I (UDP-D-galactose:D-xylose galactosyltransferase), which is one of the enzymes synthesizing the linkage region between the core protein and glycosaminoglycan chains of proteoglycan. For this method, the reaction mixture contained a fluorescent substrate, 4-methylumbelliferyl-beta-D-xyloside as an acceptor, UDP-galactose as a donor and D-galactal as a competitive inhibitor of endogenous beta-galactosidase in the enzyme solution. The reaction mixture was incubated at 37 degrees C with enzyme solution prepared from an extract of cultured cells, and galactosyl-xylosyl-4-methylumbelliferone was produced as a reaction product. Measurement of galactosyltransferase I activity was performed by separation and quantitative analysis of this reaction product using high-performance liquid chromatography. Utilizing this method, easier and more sensitive detection of galactosyltransferase I activity in a cell-free system became possible. Application of the method revealed that cultured human skin fibroblasts contained galactosyltransferase I activity.
