Abstract
BACKGROUND α-l-Fucose confers unique functions for fucose-containing biomolecules such as human milk oligosaccharides. α-l-Fucosidases can serve as desirable tools in the application of fucosylated saccharides. Discovering novel α-l-fucosidases and elucidating their enzyme properties are always worthy tasks. RESULTS A GH95 family α-l-fucosidase named Afc95A_Wf was cloned from the genome of the marine bacterium Wenyingzhuangia fucanilytica and expressed in Escherichia coli. It exhibited maximum activity at 40 °C and pH 7.5. Afc95A_Wf defined a different substrate specificity among reported α-l-fucosidases, which was capable of hydrolyzing α-fucoside in CNP-fucose, Fucα1-2Galβ1-4Glc and Galβ1-4(Fucα1-3)Glc, and showed a preference for α1,2-fucosidic linkage. It adopted Asp residue in the amino acid sequence at position 391, which was distinct from the previously acknowledged residue of Asn. The predicted tertiary structure and site-directed mutagenesis revealed that Asp391 participates in the catalysis of Afc95A_Wf. The differences in the substrate specificity and catalytic site shed light on that Afc95A_Wf adopted a novel mechanism in catalysis. CONCLUSION A GH95 family α-l-fucosidase (Afc95A_Wf) was cloned and expressed. It showed a cleavage preference for α1,2-fucosidic linkage to α1,3-fucosidic linkage. Afc95A_Wf demonstrated a different substrate specificity and a residue at an important catalytic site compared with known GH95 family proteins, which revealed the occurrence of diversity on catalytic mechanisms in the GH95 family. © 2024 Society of Chemical Industry.

Abstract
Sulfated fucan from sea cucumber is mainly consists of L-fucose and sulfate groups. Recent studies have confirmed that the structure of sulfated fucan mainly consists of repeating units, typically tetrasaccharides. However, there is growing evidence indicating the presence of irregular domains with heterogeneous units that have not been extensively explored. Moreover, as a key contributor to the nutritional benefits of sea cucumbers, sulfated fucan demonstrates a range of biological activities, such as anti-inflammatory, anticancer, hypolipidemic, anti-hyperglycemic, antioxidant, and anticoagulant properties. These biological activities are profoundly influenced by the structural features of sulfated fucan including molecular weight and distribution patterns of sulfate groups. The latest research indicates that sulfated fucan is dispersed in the extracellular matrix of the body wall of sea cucumbers. This article aimed to review the research progress on the in-situ distribution, structures, structural elucidation strategies, functions, and structure-activity relationships of sulfated fucan, especially in the last decade. It also provided insights into the major challenges and potential solutions in the research and development of sulfated fucan. Moreover, the fucanase and carbohydrate binding modules are anticipated to play pivotal roles in advancing this field.

Characterization and Structural Analysis of a Novel Carbohydrate-Binding Module from Family 96 with Chondroitin Sulfate-Specific Binding Capacity. JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY 2024; 72:13196-13204.

Abstract
Chondroitin sulfate (CS) is the predominant glycosaminoglycan within the human body and is widely applied in various industries. Carbohydrate-binding modules (CBMs) possessing the capacity for carbohydrate recognition are verified to be important tools for polysaccharide investigation. Only one CS-specific CBM, PhCBM100, has hitherto been characterized. In the present study, two CBM96 domains present in the same putative PL8_3 chondroitin AC lyase were discovered and recombinantly expressed. The results of microtiter plate assays and affinity gel electrophoresis assays showed that the two corresponding proteins, DmCBM96-1 and DmCBM96-2, bind specifically to CSs. The crystal structure of DmCBM96-1 was determined at a 2.20 Å resolution. It adopts a β-sandwich fold comprising two antiparallel β-sheets, showing structural similarities to TM6-N4, which is the founding member of the CBM96 family. Site mutagenesis analysis revealed that the residues of Arg27, Lys45, Tyr51, Arg53, and Arg157 are critical for CS binding. The characterization of the two CBM96 proteins demonstrates the diverse ligand specificity of the CBM96 family and provides promising tools for CS investigation.

Abstract
Long-term and excessive alcohol consumption can lead to the development of alcoholic liver disease (ALD), characterized by oxidative damage, intestinal barrier injury, and disruption of intestinal microbiota. In this study, we extracted fucoidan (Aj-FUC) from Apostichopus japonicus using enzymatic methods and characterized its structure. The ALD model was established in male Balb/c mice using 56° Baijiu, with silymarin as a positive control. Mice were orally administered 100 mg/kg·bw and 300 mg/kg·bw of Aj-FUC for 28 days to evaluate its effects on liver injury in ALD mice and explore its potential role in modulating the gut-liver axis. The results showed significant improvements in histopathological changes and liver disease in the Aj-FUC group. Aj-FUC treatment significantly increased the levels of glutathione (GSH) and glutathione peroxidase (GSH-Px) while weakly reduced the elevation of malondialdehyde (MDA) induced by ALD. It also regulated the Nrf2/HO-1 signaling pathway, collectively alleviating hepatic oxidative stress. Aj-FUC intervention upregulated the expression of ZO-1 and Occludin, thus contributing to repair the intestinal barrier. Additionally, Aj-FUC increased the content of short-chain fatty acids (SCFAs) and regulated the imbalance in gut microbiota. These results suggested that Aj-FUC alleviates ALD by modulating the gut-liver axis homeostasis. It may prove to be a useful dietary supplement in the treatment of alcoholic liver damage.

Abstract
BACKGROUND Agarose, mainly composed of 3,6-anhydro-α-l-galactopyranose (LA) and β-d-galactopyranose (G) units, is an important polysaccharide with wide applications in food, biomedical and bioengineering industries. Carbohydrate-binding modules (CBMs) are favorable tools for the investigations of polysaccharides. Few agarose-binding CBMs have been hitherto reported, and their binding specificity is unclear. RESULTS An unknown domain with a predicted β-sandwich fold was discovered from a β-agarase of the marine bacterium Wenyingzhuangia fucanilytica CZ1127T . The expressed protein WfCBM101 could bind to agarose and exhibited relatively weak affinity for porphyran, with no affinity for the other seven examined polysaccharides. The protein binds to the tetrasaccharide (LA-G)2 , but not to the major tetrasaccharide contained in porphyran. The sequence novelty and well-defined binding function of WfCBM101 shed light on a novel CBM family (CBM101). Furthermore, the feasibility of WfCBM101 for visualizing agarose in situ was confirmed. CONCLUSION A novel CBM, WfCBM101, with a desired specificity for agarose was discovered and characterized, which represents a new CBM family. The CBM could be utilized as a promising tool for studies of agarose. © 2023 Society of Chemical Industry.

Abstract
Sulfated polysaccharides of brown algae, fucoidans, are known for their anticoagulant properties, similar to animal heparin. Their complex and irregular structure is the main bottleneck in standardization and in defining the relationship between their structure and bioactivity. Fucoidan-active enzymes can be effective tools to overcome these problems. In the present work, we identified the gene fwf5 encoding the fucoidan-active endo-fucanase of the GH168 family in the marine bacterium Wenyingzhuangia fucanilytica CZ1127T. The biochemical characteristics of the recombinant fucanase FWf5 were investigated. Fucanase FWf5 was shown to catalyze the endo-type cleavage of the 1→4-O-glycosidic linkages between 2-O-sulfated α-L-fucose residues in fucoidans composed of the alternating 1→3- and 1→4-linked residues of sulfated α-L-fucose. This is the first report on the endo-1→4-α-L-fucanases (EC 3.2.1.212) of the GH168 family. The endo-fucanase FWf5 was used to selectively produce high- and low-molecular-weight fucoidan derivatives containing either regular alternating 2-O- and 2,4-di-O-sulfation or regular 2-O-sulfation. The polymeric 2,4-di-O-sulfated fucoidan derivative was shown to have significantly greater in vitro anticoagulant properties than 2-O-sulfated derivatives. The results have demonstrated a new type specificity among fucanases of the GH168 family and the prospects of using such enzymes to obtain standard fucoidan preparations with regular sulfation and high anticoagulant properties.

Abstract
Sulfated fucans attract increasing research interests in recent decades for their various physiological activities. Fucanases are indispensable tools for the investigation of sulfated fucans. Herein, a novel GH168 family endo-1,3-fucanase was cloned from the genome of marine bacterium Wenyingzhuangia fucanilytica. The expressed protein Fun168D was a processive endo-acting enzyme. Ultra performance liquid chromatography-high resolution mass spectrum and NMR analyses revealed that the enzyme cleaved the α-1 → 3 bonds between α-l-Fucp(2OSO3-) and α-l-Fucp(2OSO3-) in sulfated fucan from Isostichopus badionotus, and α-1 → 3 bonds between α-l-Fucp(2OSO3-) and α-l-Fucp(2,4OSO3-) in sulfated fucan from Holothuria tubulosa. Fun168D would prefer to accept α-l-Fucp(2,4OSO3-) than α-l-Fucp(2OSO3-) at subsite +1, and could tolerate the absence of fucose residue at subsite +2. The novel cleavage specificity and hydrolysis pattern revealed the presence of diversity within the GH168 family, which would facilitate the development of diverse biotechnological tools for the molecule tailoring of sulfated fucan.

Abstract
Sulfated fucans are important marine polysaccharides with various biological and biomedical activities. Fucanases are favorable tools to establish the structure-activity relationships of sulfated fucans. Herein, gene fun174A was discovered from the genome of marine bacterium Wenyingzhuangia aestuarii OF219, and none of the pre-defined glycosidic hydrolase domains were predicted in the protein sequence of Fun174A. Recombinant Fun174A demonstrated a low optimal reaction pH at 5.5. It might degrade sulfated fucans in an endo-processive manner. Glycomics and NMR analyses proved that it specifically hydrolyzed α-1,3-l-fucoside bonds between 2-O-sulfated and non-sulfated fucose residues in the sulfated fucan from sea cucumber Isostichopus badionotus. D119, E120 and E218 were critical for the activity of Fun174A, as identified by site-directed mutagenesis. Three homologs of Fun174A were confirmed to exhibit endo-1,3-fucanase activities. The novelty on sequences of Fun174A and its homologs reveals a new glycoside hydrolase family, GH174.

Abstract
Fucoidanase is an unstable enzyme with high specificity that requires a large about of time to screen it from microorganisms. In this study, enzymatic hydrolysis was used to produce low-molecular-weight fucoidan from microorganisms via the degradation of high-molecular-weight fucoidan without damage to the sulfate esterification structure of oligosaccharide. The microbial strain HN-25 was isolated from sea mud and was made to undergo mutagenicity under ultraviolet light. Fucoidanase was extracted via ultrasonication and its enzymatic activity was improved via optimization of the ultrasonic conditions. The enzymatic properties and degradation efficiency of fucoidanase were characterized. The microbial strain HN-25 is a Gram-negative aerobic and rod-shaped-cell bacterium, and therefore was identified as Cobetia amphilecti via 16s rDNA. The results proved that fucoidanase is a hydrolytic enzyme with a molecular weight of 35 kDa and with high activity and stability at 30 °C and pH 8.0. The activity of fucoidanase was significantly enhanced by sodium and calcium ions and inhibited by a copper ion and ethylenediaminetetraacetate (EDTA). There was a significant decrease in the molecular weight of fucoidan after enzymatic hydrolysis. The low-molecular-weight fuicodan was divided into four fractions, mainly concentrated at F3 (20~10 kDa) and F4 (≤6 kDa). These consequences suggest that fucoidanase obtained from Cobetia amphilecti is stable and efficient and could be a good tool in the production of bioactive compounds.

Mei X, Liu G, Shen J, Chen G, Zhang Y, Xue C, Chang Y. Discovery of a sulfated fucan-specific carbohydrate-binding module: The first member of a new carbohydrate-binding module family. Int J Biol Macromol 2023; 238:124037. [PMID: 36924869 DOI: 10.1016/j.ijbiomac.2023.124037] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Revised: 02/22/2023] [Accepted: 03/09/2023] [Indexed: 03/16/2023]
Abstract
Sulfated fucan is an important functional polysaccharide with various physiological activities. Carbohydrate-binding module (CBM) is a representative class of carbohydrate-binding protein, which could be employed as a favorable tool for the investigations and applications of polysaccharides. Nevertheless, only one confirmed sulfated fucan-binding CBM has been hitherto reported. In the present study, an unknown domain with a predicted β-sandwich fold was discovered from a fucanase Fun174A, and further cloned and heterologously expressed in Escherichia coli. The expressed protein Fun174A-CBM displayed a specific binding capacity to sulfated fucan. The bio-layer interferometry assays showed that the protein could bind to the sulfated fucan tetrasaccharide with an affinity constant of 2.83 × 10-4 M. Fun174A-CBM shared no significant sequence similarity to any identified CBMs, indicating that it represents a new CBM family. The discovery of Fun174-CBM and the novel CBM family would be beneficial to the investigations of sulfated fucan-binding proteins.

Abstract
Sulfated fucans are important polysaccharides with diverse biological and biomedical activities. Carbohydrate-binding modules (CBMs) could serve as beneficial tools for the investigation of polysaccharides. Nevertheless, no sulfated fucan-binding CBM has been hitherto discovered. In the present study, a novel CBM47 domain was cloned from the marine bacterium Wenyingzhuangia fucanilytica, and heterologously expressed in Escherichia coli. The expressed protein WfCBM47 exhibited a specific binding capacity to sulfated fucans with the backbone composed of 1,3-α-l-fucopyranose residues. Furthermore, a fluorescent probe was successfully constructed by fusing WfCBM47 with a green fluorescent protein, based on which the in situ visualization of sulfated fucan in the sea cucumber (Apostichopus japonicus) body wall was implemented for the first time. The discovery of WfCBM47 provided a promising tool for future investigations on sulfated fucans.

Abstract
Fucoidans are sulfated, fucose-rich marine polysaccharides primarily found in cell walls of brown seaweeds (macroalgae). Fucoidans are known to possess beneficial bioactivities depending on their structure and sulfation degree. Here, we report the first functional characterization and the first crystal structure of a prokaryotic sulfatase, PsFucS1, belonging to sulfatase subfamily S1_13, able to release sulfate from fucoidan oligosaccharides. PsFucS1 was identified in the genome of a Pseudoalteromonas sp. isolated from sea cucumber gut. PsFucS1 (57 kDa) is Ca2+ dependent and has an unusually high optimal temperature (68 °C) and thermostability. Further, the PsFucS1 displays a unique quaternary hexameric structure comprising a tight trimeric dimer complex. The structural data imply that this hexamer formation results from an uncommon interaction of each PsFucS1 monomer that is oriented perpendicular to the common dimer interface (~ 1500 Å2) that can be found in analogous sulfatases. The uncommon interaction involves interfacing (1246 Å2) through a bundle of α-helices in the N-terminal domain to form a trimeric ring structure. The high thermostability may be related to this unusual quaternary hexameric structure formation that is suggested to represent a novel protein thermostabilization mechanism.

Abstract
Fucoidans are a class of sulfated fucose-containing bioactive polysaccharides produced by brown algae. The biological effects exhibited by fucoidans are thought to be related to their sulfation. However, the lack of methods for sulfation control does not allow for a reliable conclusion about the influence of the position of certain sulfate groups on the observed biological effects. We identified the gene encoding the endo-acting fucoidan sulfatase swf5 in the marine bacterium Wenyingzhuangia fucanilytica CZ1127T. This is the first report on the sequence of fucoidan endo-sulfatase. Sulfatase SWF5 belongs to the subfamily S1_22 of the family S1. SWF5 was shown to remove 4O-sulfation in fucoidans composed from the alternating α-(1→3)- and α-(1→4)-linked residues of sulfated L-fucose but not from fucoidans with the α-(1→3)-linked backbone. The endo-sulfatase was used to selectively prepare 4O-desulfated fucoidan derivatives. It was shown that the 4O-desulfated fucoidans inhibit colony formation of DLD-1 and MCF-7 cells less effectively than unmodified fucoidans. Presumably, 4O-sulfation makes a significant contribution to the anticancer activity of fucoidans.

Abstract
Wound healing involves a complex cascade of cellular, molecular, and biochemical responses and signaling processes. It consists of successive interrelated phases, the duration of which depends on a multitude of factors. Wound treatment is a major healthcare issue that can be resolved by the development of effective and affordable wound dressings based on natural materials and biologically active substances. The proper use of modern wound dressings can significantly accelerate wound healing with minimum scar mark. Sulfated polysaccharides from seaweeds, with their unique structures and biological properties, as well as with a high potential to be used in various wound treatment methods, now undoubtedly play a major role in innovative biotechnologies of modern natural interactive dressings. These natural biopolymers are a novel and promising biologically active source for designing wound dressings based on alginates, fucoidans, carrageenans, and ulvans, which serve as active and effective therapeutic tools. The goal of this review is to summarize available information about the modern wound dressing technologies based on seaweed-derived polysaccharides, including those successfully implemented in commercial products, with a focus on promising and innovative designs. Future perspectives for the use of marine-derived biopolymers necessitate summarizing and analyzing results of numerous experiments and clinical trial data, developing a scientifically substantiated approach to wound treatment, and suggesting relevant practical recommendations.

Abstract
Sulfated fucans are important marine polysaccharides widely distributed in brown algae and echinoderms, which gained increasing research interest for their various biological and biomedical activities. Fucanases could serve as tools in the bioconversion and structural investigation of sulfated fucans. A few gene-defined endo-1,4-fucanases have been characterized, while the sequence of endo-1,3-fucanase remain unstudied. Here, an endo-1,3-fucanase gene funA was screened from the genome of marine bacterium Wenyingzhuangia fucanilytica CZ1127T using transcriptomics. None of the previously reported glycoside hydrolase domains were predicted in the enzyme FunA, which hydrolyzed sulfated fucans in a random endo-acting manner. Ultrahigh performance size exclusion chromatography-mass spectrometry and nuclear magnetic resonance analyses revealed that FunA specifically cleaves α-1,3 glycosidic linkage between 2-O-sulfated and non-sulfated fucose residues. FunA exhibited transglycosylating activity with glycerin, methanol, and L-fucose as acceptors. D206 and E264 were critical for the functioning of FunA as identified by the site-directed mutagenesis. Another five homologs of FunA were confirmed to possess endo-1,3-fucanase activities. This is the first report on the sequence of endo-1,3-fucanase. The novelty of FunA and its homologs in sequences and activity shed light on a novel glycoside hydrolase family, GH168.

Abstract
Aquatic protein hydrolysates are usually associated with unpleasant odors and high fat content, which seriously restricts their industrial utilization. In this study, chitosans with different molecular weights produced by hydrogen peroxide degradation were applied to establish a flocculation method, using for the deodorization and defatting of oyster (Crassostrea gigas) hydrolysates. GC-MS analysis showed that the method markedly decreased the content of the fishy odor constituents. Up to 92 % fat and part of the heavy metals were effectively removed. Protein recovery percentage and solid recovery percentage were 83.43 ± 0.35 % and 76.36 ± 0.52 %, respectively, at the optimum dose (150 mg/L) of chitosan (83 % of deacetylation degree, 77 kDa). Thus, chitosan flocculation-coupled centrifugation (5000g, 1 min) can effectively solve the current drawbacks of engineering disc centrifuges and can be industrially used for defatting and deodorization during aquatic food processing.

Abstract
Fucoidans are multifunctional marine macromolecules that are subjected to numerous and various downstream processes during their production. These processes were considered the most important abiotic factors affecting fucoidan chemical skeletons, quality, physicochemical properties, biological properties and industrial applications. Since a universal protocol for fucoidans production has not been established yet, all the currently used processes were presented and justified. The current article complements our previous articles in the fucoidans field, provides an updated overview regarding the different downstream processes, including pre-treatment, extraction, purification and enzymatic modification processes, and shows the recent non-traditional applications of fucoidans in relation to their characters.

Abstract
Porphyra is one of the most consumed types of red algae. Porphyran is the major polysaccharide extracted from Porphyra, and it is composed of alternating 4-linked α-l-galactopyranose-6-sulfate (L6S) and 3-linked β-d-galactopyranose (G) residues. β-Porphyranases are promising tools for degrading porphyran; however, few enzymes have been reported, and the biochemical properties of porphyranases are still unclear. Here, a novel GH16 β-porphyranase, designated as Por16A_Wf, was cloned from Wenyingzhuangia fucanilytica and expressed in Escherichia coli. Its biochemical properties and hydrolysis pattern were characterized. Por16A_Wf exhibited stable activity on a wide pH scale from 3.5 to 11.0. Glycomics analysis using LC-MS revealed that Por16A_Wf specifically hydrolyzed the glycosidic linkage of G-L6S, whereas it tolerated 3,6-anhydro-α-l-galactopyranose and methyl-d-galactose in -2 and +2 subsites, respectively. Por16A_Wf could be applied as a biotechnological tool for tailoring porphyran, which would serve in directional preparation of its disaccharide, producing products with various molecular weights and facilitating investigation of the structural heterogeneity of Porphyra polysaccharides.

Abstract
Sulfated fucans, often denoted as fucoidans, are highly variable cell wall polysaccharides of brown algae, which possess a wide range of bioactive properties with potential pharmaceutical applications. Due to their complex architecture, the structures of algal fucans have until now only been partly determined. Enzymes capable of hydrolyzing sulfated fucans may allow specific release of defined bioactive oligosaccharides and may serve as a tool for structural elucidation of algal walls. Currently, such enzymes include only a few hydrolases belonging to the glycoside hydrolase family 107 (GH107), and little is known about their mechanistics and the substrates they degrade. In this study, we report the identification and recombinant production of three novel GH107 family proteins derived from a marine metagenome. Activity screening against a large substrate collection showed that all three enzymes degraded sulfated fucans from brown algae in the order Fucales. This is in accordance with a hydrolytic activity against α-1,4-fucosidic linkages in sulfated fucans as reported for previous GH107 members. Also, the activity screening gave new indications about the structural differences in brown algal cell walls. Finally, sequence analyses allowed identification of the proposed catalytic residues of the GH107 family. The findings presented here form a new basis for understanding the GH107 family of enzymes and investigating the complex sulfated fucans from brown algae. DATABASE: The assembled metagenome and raw sequence data is available at EMBL-EBI (Study number: PRJEB28480). Sequences of the GH107 fucanases (Fp273, Fp277, and Fp279) have been deposited in GenBank under accessions MH755451-MH755453.

Abstract
Alginate is the major constituent of brown algae and a commercially important polysaccharide with wide applications. Alginate lyases are desired tools for degrading alginate. Based on the genome mining of marine bacterium Wenyingzhuangia funcanilytica, an alginate lyase Aly7B_Wf was discovered, cloned and expressed in Escherichia coli. Aly7B_Wf belonged to subfamily 6 of PL7 family. Its biochemical properties, kinetic constants, substrate specificity and degradation pattern were clarified. The enzyme is an endo-acting bifunctional alginate lyase, and preferably cleaved polymannuronate (polyM). The Km (0.0237 ± 0.0004 μM, 0.0105 ± 0.0002 mg/mL) and kcat/Km (1180.65 ± 19.81 μM-1 s-1, 2654.34 ± 44.54 mg-1 ml s-1) indicated relatively high substrate-binding affinity and catalysis efficiency of Aly7B_Wf. By using mass spectrometry, final products of alginate degraded by Aly7B_Wf were identified as alginate hexasaccharide to disaccharide, and final products of polyguluronate (polyG) and polyM were confirmed as tetrasaccharide to disaccharide. The most predominant oligosaccharide in the final products of polyG and polyM was trisaccharide and disaccharide respectively. The broad substrate specificity, endo-acting degradation pattern and high catalysis efficiency suggested that Aly7B_Wf could be utilizied as a potential tool for tailoring the size of alginate and preparing alginate oligosaccharides.

Abstract
Fucoidans belong to a structurally heterogeneous class of sulfated polysaccharides isolated from brown algae. They have a wide spectrum of biological activities. The complex structures of these polysaccharides hinder structure-activity relationships determination. Fucoidan sulfatases can make useful tools for the determination of the fine chemical structure of fucoidans. In this study, identification and preparation of two recombinant sulfatases able to catalyze the cleavage of sulfate groups from fragments of fucoidan molecules is described for the first time. Two genes of sulfatases swf1 and swf4 of the marine bacterium Wenyingzhuangia fucanilytica CZ1127T were cloned and the proteins were produced in Escherichia coli cells. Sulfatases SWF1 and SWF4 are assigned to S1_17 and S1_25 subfamilies of formylglycine-dependent enzymes of S1 family (SulfAtlas). Some molecular and biochemical characteristics of recombinant fucoidan sulfatases have been studied. Detailed specificity and catalytic features of sulfatases were determined using various sulfated fucooligosaccharides. Structures of products produced by SWF1 and SWF4 were established by nuclear magnetic resonance (NMR) spectroscopy. Based on the obtained data, the enzymes are classified as fucoidan exo-2O-sulfatase (SWF1) and fucoidan exo-3O-sulfatase (SWF4). In addition, we demonstrated the sequential action of sulfatases on 2,3-di-O-sulfated fucooligosacchrides, which indicates an exolitic degradation pathway of fucoidan by a marine bacterium W. fucanilytica CZ1127T.

Abstract
A variety of bioactivities has been established for fucoidan extracted from sea cucumber, whereas its structure-activity relationships have been seldom investigated. In this study, sea cucumber ( Thelenota ananas) fucoidans with different molecular weights were prepared with enzymatic degradation. The chain stiffness and molecular size decreased with the decreasing of molecular weight. Fucoidans with molecular weight of 1380.0, 828.7, and 483.0 kDa exhibited random coil conformations, while fucoidan molecular weight of 215.0 kDa existed as sphere in solution. All examined fucoidans could effectively prevent the ethanol-induced gastric ulcer, of which mechanism involved antioxidation and anti-inflammation. Within the range of the study, the performance of fucoidans adopted random coil conformations declined with the decreasing of molecular weight, and the performance recovered when the chain conformation transited from coil to sphere, indicating the subtle influences of molecular weight and chain conformation on the gastric protective activity of sea cucumber fucoidan.

Abstract
Cyclophosphamide (cy) is a widely used cancer drug. Many researchers have focused on the prevention and alleviation of its side effects, particularly damage to the intestinal mucosal barrier. In this study, we examined the effects of fucoidan, isolated from Acaudina molpadioides, on mice with intestinal mucosal damage induced by cyclophosphamide. Our results showed that fucoidan intervention could relieve injury such as decreasing inflammation and increasing the expression of tight junction proteins, and 50 kDa fucoidan significantly increased the abundance of short chain fatty acid (SCFA) producer Coprococcus, Rikenella, and Butyricicoccus (p < 0.05, p < 0.001, and p < 0.05, respectively) species within the intestinal mucosa compared with the cyclophosphamide group, as determined by 16S rDNA gene high-throughput sequencing. In addition, SCFAs, particularly propionate, butyrate, and total SCFAs, were increased in the feces, and SCFA receptors were upregulated in the small intestine. The protective effects of fucoidan on cyclophosphamide treatment may be associated with gut microflora, and 50 kDa fucoidan had superior effects. Therefore, fucoidan may have applications as an effective supplement to protect against intestinal mucosal barrier damage during chemotherapy.

Abstract
α-l-Fucosyl residues are frequently found in oligosaccharides, polysaccharides and glycoconjugates which play fundamental roles in various biological processes. α-l-Fucosidases, glycoside hydrolases for catalyzing the removal of α-l-fucose, can serve as desirable tools in the study and the modification of fucose-containing biomolecules. In this study, an α-l-fucosidase named as Alf1_Wf was purified from a marine bacterium Wenyingzhuangia fucanilytica by using a combination of chromatographic procedures. The sequence of Alf1_Wf was identified via proteomics analysis against the predicted proteome of the bacterium. Recombinant Alf1_Wf with 6×His tag was expressed in E. coli and showed α-l-fucosidase activity. Sequence annotation revealed that Alf1_Wf contained a combination of GH29 catalytic domain and CBM35 accessory domain. Alf1_Wf was confirmed as a member of GH29-A subfamily based on the phylogenetic analysis. Furthermore, biochemical properties and kinetic characteristics of the enzyme were also determined. Substrate specificity determination showed that Alf1_Wf was capable in hydrolyzing α1,4-fucosidic linkage and synthetic substrate pNP-fucose. Besides, Alf1_Wf could act on partially degraded fucoidan. This study successfully purified, identified, cloned, expressed and characterized a novel α-l-fucosidase, and meanwhile revealed a new multidomain structure of glycoside hydrolase. The knowledge gained from this study should facilitate the further research and application of α-l-fucosidases.

Abstract
A Gram-staining-negative, rod-shaped, strictly aerobic, non-flagellated, non-gliding and yellow-pigmented bacterial strain, designated as strain CZ1127T, capable of utilizing sulfated fucan, was isolated from shallow coastal seawater of Jiaozhou Bay, Qingdao, PR China. Its taxonomic position was investigated by a polyphasic approach. CZ1127T grew at 15-37 °C (optimum, 25 °C), pH 5.5-9.0 (optimum, pH 6.5-7.5) and in the presence of 0-4 % (w/v) NaCl [optimum, 0-3 % (w/v)]. CZ1127T contained MK-6 as the sole menaquinone, and iso-C15 : 0, iso-C17 : 0 3-OH, C16 : 1ω7c/C16 : 1ω6c and iso-C15 : 0 3-OH as its major fatty acids. The DNA G+C content of strain CZ1127T was 32.2 mol%. Phylogenetic analysis based on the 16S rRNA gene indicated that strain CZ1127T clustered with members of the genus Wenyingzhuangia and was closely related to Wenyingzhuangia marina CGMCC 1.12162T (97.4 % 16S rRNA gene sequence similarity) and Wenyingzhuangia gracilariae KCTC 42246T (96.1 %). The DNA-DNA relatedness between strain CZ1127T and W. marina CGMCC 1.12162T was 41.9±1.5 %. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, CZ1127T represents a novel species of the genus Wenyingzhuangia, for which the name Wenyingzhuangia fucanilytica sp. nov. is proposed. The type strain is CZ1127T (=CCTCC AB 2015089T=KCTC 42864T).

Abstract
In this study, 33 different polysaccharides were prepared to investigate the structure-activity relationships between the polysaccharides, mainly from marine algae, and anti-complement activity in the classical pathway. Factors considered included extraction methods, fractionations, molecular weight, molar ratio of galactose to fucose, sulfate, uronic acid (UA) content, linkage, branching, and the type of monosaccharide. It was shown that the larger the molecular weights, the better the activities. The molar ratio of galactose (Gal) to fucose (Fuc) was a positive factor at a concentration lower than 10 µg/mL, while it had no effect at a concentration more than 10 µg/mL. In addition, sulfate was necessary; however, the sulfate content, the sulfate pattern, linkage and branching had no effect at a concentration of more than 10 µg/mL. Moreover, the type of monosaccharide had no effect. Laminaran and UA fractions had no activity; however, they could reduce the activity by decreasing the effective concentration of the active composition when they were mixed with the active compositions. The effect of the extraction methods could not be determined. Finally, it was observed that sulfated galactofucan showed good anti-complement activity after separation.

Abstract
In recent years, the research of fucoidans has steadily increased. The interest in these substances is due to their various biological activities. Despite a wide range of biological activity and the lack of oral toxicity, fucoidans remain relatively unexploited as a source of medicines because of their heterogeneity. Enzymes that degrade polyanionic polysaccharides are widely used for establishing their structures and structure-activity relationships. Sometimes, to obtain preparations of polysaccharides with standard characteristics, for example, medicines and food supplements, enzymatic treatment can be also applied. Only a few sources of enzymes with fucoidanase activity have been described, and only a few studies regarding the isolation and characterization of fucoidanases have been performed. The data on the specificity of fucoidanases: the type of cleaved glycoside bond, the relation between catalytic activity and the degree of substrate sulfation are scarce. The review summarizes achievements in the research of fucoidanases, mechanisms of enzymatic degradation of fucoidans, as well as of structures of sulfated fucooligosaccharides obtained under the action of fucoidanases.

Abstract
A novel fucoidan, which consists of a 1 → 3-linked tetrafucose repeating unit that is distinctive in its sulphation pattern, was isolated from the sea cucumber Acaudina molpadioides. In the present study, we examined the anti-adipogenic effect of the fucoidan from Acaudina molpadioides (Am-FUC) in vitro and in vivo. Results showed that Am-FUC exhibited an inhibitory effect on the proliferation and differentiation of 3T3-L1 cells. Am-FUC suppressed the differentiation of 3T3-L1 cells, decreasing the content of intracellular triglyceride by 34.07% at the concentration of 200 μg ml(-1). In vivo experiments showed that the subcutaneous, perirenal and epididymal fat content of Am-FUC-treated mice were significantly reduced compared to the HFFD-fed mice. A reverse transcriptase-polymerase chain reaction assay revealed that Am-FUC significantly increased the mRNA expressions of Wnt/β-catenin pathway related factors, namely, Wnt10b, β-catenin, Fz and LRP5, and decreased that of the key transcriptional factors, such as SREBP-1c, PPARγ and C/EBPα. β-Catenin acts as an anti-adipogenic factor to inhibit the expression of PPARγ and C/EBPα, while SREBP-1c can promote the adipocyte differentiation by enhancing the activity of PPARγ. Western blotting results showed that Am-FUC significantly increased the protein level of the total β-catenin and nuclear β-catenin and suppressed that of the SREBP-1c. Am-FUC also significantly inhibited the mRNA expressions of the lipid synthesis related genes such as FAS and GPAT, while had no effect on that of the lipolysis related genes such as HSL and ATGL. These findings suggest that Am-FUC possesses marked anti-adipogenic activity by modulating the Wnt/β-catenin pathway and down-regulating the expression of SREBP-1c.

Abstract
Sea cucumber fucoidan is a major bioactive component of sea cucumber. Sea cucumber is widely consumed in East Asian countries as healthy food. Employing the degrading enzyme from the marine bacterium strain Flavobacteriaceae CZ1127, sea cucumber (Acaudina molpadioides) fucoidan oligosaccharides were prepared by enzymatic hydrolysis. The oligosaccharide profile of the hydrolysate was determined by liquid chromatography coupled with mass spectrometry (LC-MS). With the assistance of LC-MS, four major oligosaccharides in the hydrolysate were purified. By using tandem mass spectrometry and nuclear magnetic resonance, delicate structures of the oligosaccharides were verified as α-l-Fucp-1→3-α-l-Fucp(2,4OSO3(2-))-1→3-α-l-Fucp, α-l-Fucp-1→3-α-l-Fucp(2,4OSO3(2-))-1→3-α-l-Fucp-1→3-α-l-Fucp, α-l-Fucp-1→3-α-l-Fucp(2,4OSO3(2-))-1→3-α-l-Fucp-1→3-α-l-Fucp-1→3-α-l-Fucp-1→3-α-l-Fucp(2,4OSO3(2-))-1→3-α-l-Fucp and α-l-Fucp-1→3-α-l-Fucp(2,4OSO3(2-))-1→3-α-l-Fucp-1→3-α-l-Fucp-1→3-α-l-Fucp-1→3-α-l-Fucp(2,4OSO3(2-))-1→3-α-l-Fucp-1→3-α-l-Fucp.

Abstract
Fucoidan is a complex-sulfated polysaccharide distributed in various marine organisms, and the brown algae are reported as the major producer. The fucoidan is important for their high bioactive properties, like antibacterial, anticoagulant, antiviral, anti-tumor, etc., and many more to be explored. There is a strong archival support for the bioactivity and promising properties of this molecule, which creates a hope for this molecule as future drug against thrombosis and some kind of cancers. Reports other than the above bioactive properties have also been a matter of interest for the design of signal or enzyme-arrested new class of drugs. In the past three decades, the research on isolation, molecular characterization, and screening of biological applications has significantly increased. One major issue associated with this molecule is the higher size and seasonal variation in their chemical composition; to resolve the issue and maintain its bioactivity, a prioritized and literal hydrolysis process is required to be developed. Here, in this mini-review, we have tried to summarize the algal fucoidan research and the bioactivities influenced by their molecular size.
