Abstract
Daedaleopsis sinensis is a fungus that grows on wood and secretes a series of enzymes to degrade cellulose, hemicellulose, and lignin and cause wood rot decay. Wood-decaying fungi have ecological, economic, edible, and medicinal functions. Furthermore, the use of microorganisms to biodegrade lignocellulose has high application value. Genome sequencing has allowed microorganisms to be analyzed from the aspects of genome characteristics, genome function annotation, metabolic pathways, and comparative genomics. Subsequently, the relevant information regarding lignocellulosic degradation has been mined by bioinformatics. Here, we sequenced and analyzed the genome of D. sinensis for the first time. A 51.67-Mb genome sequence was assembled to 24 contigs, which led to the prediction of 12,153 protein-coding genes. Kyoto Encyclopedia of Genes and Genomes database analysis of the D. sinensis data revealed that 3,831 genes are involved in almost 120 metabolic pathways. According to the Carbohydrate-Active Enzyme database, 481 enzymes are found in D. sinensis, of which glycoside hydrolases are the most abundant. The genome sequence of D. sinensis provides insights into its lignocellulosic degradation and subsequent applications.

Abstract
Sugar oxazolines, (GlcNAc)n-oxa (n = 2, 3, 4, and 5), were synthesized from a mixture of chitooligosaccharides, (GlcNAc)n (n = 2, 3, 4, and 5), and utilized for synthesis of (GlcNAc)7 with higher elicitor activity using plant chitinase mutants as the catalysts. From isothermal titration calorimetry, the binding affinity of (GlcNAc)2-oxa toward an inactive mutant obtained from Arabidopsis thaliana GH18 chitinase was found to be higher than those of the other (GlcNAc)n-oxa (n = 3, 4, and 5). To synthesize (GlcNAc)7, the donor/acceptor substrates with different size combinations, (GlcNAc)2-oxa/(GlcNAc)5 (1), (GlcNAc)3-oxa/(GlcNAc)4 (2), (GlcNAc)4-oxa/(GlcNAc)3 (3), and (GlcNAc)5-oxa/(GlcNAc)2 (4), were incubated with hypertransglycosylating mutants of GH18 chitinases from A. thaliana and Cycas revoluta. The synthetic activities of these plant chitinase mutants were lower than that of a mutant of Bacillus circulans chitinase A1. Nevertheless, in the plant chitinase mutants, the synthetic efficiency of combination (1) was higher than those of the other combinations (2), (3), and (4), suggesting that the synthetic reaction is mostly dominated by the binding affinities of (GlcNAc)n-oxa. In contrast, the Bacillus enzyme mutant with a different subsite arrangement synthesized (GlcNAc)7 from combination (1) in the lowest efficiency. Donor/acceptor-size dependency of the enzymatic synthesis appeared to be strongly related to the subsite arrangement of the enzyme used as the catalyst. The A. thaliana chitinase mutant was found to be useful when combination (1) is employed for the substrates.

Abstract
Glycopolymers have attracted increased attention as functional polymeric materials, and simple methods for synthesizing glycopolymers remain needed. This paper reports the aqueous one-pot and chemoenzymatic synthesis of four types of glycopolymers via two reactions: the β-galactosidase-catalyzed glycomonomer synthesis using 4,6-dimetoxy triazinyl β-D-galactopyranoside and hydroxy group-containing (meth)acrylamide and (meth)acrylate derivatives as the activated glycosyl donor substrate and as the glycomonomer precursors, respectively, followed by radical copolymerization of the resulting glycomonomer and excess glycomonomer precursor without isolating the glycomonomers. The resulting glycopolymers bearing galactose moieties exhibited specific and strong interactions with the lectin peanut agglutinin as glycoclusters.

Abstract
Glycopolymers were successfully synthesised from unprotected sugars in aqueous media via a one-pot chemoenzymatic process of three reactions; the direct synthesis of 4,6-dimethoxy-1,3,5-triazin-2-yl glycosides from unprotected sugars, a glycosidase-catalysed glycosylation using the triazinyl glycoside to afford glycomonomers and a radical polymerisation. The resulting glycopolymers exhibited specific interactions with the corresponding lectin as glycoclusters.

Abstract
PoCel12A, PoCel12B, and PoCel12C are genes that encode glycoside hydrolase family 12 (GH12) enzymes in Penicillium oxalicum. PoCel12A and PoCel12B are typical GH12 enzymes that belong to fungal subfamilies 12-1 and 12-2, respectively. PoCel12C contains a low-complexity region (LCR) domain, which is not found in PoCel12A or PoCel12B and independent of fungal subfamily 12-1 or 12-2. Recombinant enzymes (named rCel12A, rCel12B and rCel12C) demonstrate existing diversity in the substrate specificities. Although most members in GH family 12 are typical endoglucanases and preferentially hydrolyze β-1,4-glucan (e.g., carboxymethylcellulose), recombinant PoCel12A is a non-typical endo-(1-4)-β-glucanase; it preferentially hydrolyzes mix-linked β-glucan (barley β-glucan, β-1,3-1,4-glucan) and slightly hydrolyzes β-1,4-glucan (carboxymethylcellulose). Recombinant PoCel12B possesses a significantly high activity against xyloglucan. A specific activity of rCel12B toward xyloglucan (239 µmol/min/mg) is the second-highest value known. Recombinant PoCel12C shows low activity toward β-glucan, carboxymethylcellulose, or xyloglucan. All three enzymes can degrade phosphoric acid-swollen cellulose (PASC). However, the hydrolysis products toward PASC by enzymes are different: the main hydrolysis products are cellotriose, cellotetraose, and cellobiose for rCel12A, rCel12B, and rCel12C, correspondingly. A synergistic action toward PASC among rCel12A and rCel12B is observed, thereby suggesting a potential application for preparing enzyme cocktails used in lignocellulose hydrolysis.

Abstract
Glycosidic compounds are indispensable molecules in living systems. Biological phenomena such as cell wall formation, energy storage, and cell recognition strongly depend on the multi-functional characters of these substances. Development of highly regio- and stereoselective glycosylation reactions is necessary to provide sufficient amounts of specific compounds in basic research as well as for applications in industry. This review presents an overview of chemical and chemo-enzymatic glycosylations that have been developed during my forty-year academic career in the field of glyco-science. In the course of these studies, several new concepts such as "Direct Anomeric Activation", "Glyco-Process Chemistry" and "Glyco-Chemistry Cycles" have been established.

Abstract
This study describes the synthesis of triazine-based dehydrocondensing reagents substituted by amido substituents and demonstrates their efficiency for dehydrocondensing reactions in MeOH and THF. N-Phenylbenzamido-substituted chlorotriazine is readily converted to a stable, non-hygroscopic triazinylammonium-based dehydrocondensing reagent that is superior to 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (DMT-MM) in terms of its reactivity in dehydrocondensing reactions.

Abstract
Three genes encoding glycoside hydrolase family 12 (GH12) enzymes from Lentinula edodes, namely Lecel12A, Lecel12B, and Lecel12C, were newly cloned by PCR using highly conserved sequence primers. To investigate enzymatic properties, recombinant enzymes encoded by L. edodes DNAs and GH12 genes from Postia placenta (PpCel12A and PpCel12B) and Schizophyllum commune (ScCel12A) were prepared in Brevibacillus choshinensis. Recombinant LeCel12A, PpCel12A, and PpCel12B, which were grouped in GH12 subfamily 1, preferentially hydrolyzed 1,3-1,4-β-glucan. By contrast, LeCel12B, LeCel12C, and ScCel12A, members of the subfamily 2, exhibited specific hydrolysis of xyloglucan. These results suggest that two subfamilies of GH12 are separated based on the substrate specificity. Transcript levels of L. edodes genes increased 72 h after growth of L. edodes mycelia cells in the presence of plant cell wall polymers such as xyloglucan, 1,3-1,4-β-glucan, and cellulose. These results suggest that L. edodes GH12 enzymes have evolved to hydrolyze 1,3-1,4-β-glucan and xyloglucan, which might enhance hyphal extension and nutrient acquisition.
