In this study, we compare the antibacterial properties of two fractions of fucoidan from the brown algae <i>Fucus vesiculosus</i> gathered in the littoral of the Barents Sea and sampled at different stages of purification. The crude fraction of fucoidan was isolated from algae by extraction with aqueous ethanol and sonication. The purified fraction was obtained by additional treatment of the crude fraction with a solution of calcium chloride. The structural features of both fractions were characterized in detail and their antibacterial effects against several Gram-positive and Gram-negative bacteria were compared by photometry, acridine orange staining assay, and atomic force microscopy. Fucoidan inhibited growth in all of the above microorganisms, showing a bacteriostatic effect with minimum inhibitory concentrations (MIC) in the range between 4 and 6 mg/mL, with <i>E. coli</i> being the most sensitive to both fractions.

\n Fucoidans, sulfated polysaccharides found in cell walls of brown algae, are considered as a promising antimicrobial component for various applications in medicine and the food industry. In this study, we compare the antibacterial properties of two fractions of fucoidan from the brown algae Fucus vesiculosus gathered in the littoral of the Barents Sea and sampled at different stages of purification. The crude fraction of fucoidan was isolated from algae by extraction with aqueous ethanol and sonication. The purified fraction was obtained by additional treatment of the crude fraction with a solution of calcium chloride. The structural features of both fractions were characterized in detail and their antibacterial effects against several Gram-positive and Gram-negative bacteria were compared by photometry, acridine orange staining assay, and atomic force microscopy. Fucoidan inhibited growth in all of the above microorganisms, showing a bacteriostatic effect with minimum inhibitory concentrations (MIC) in the range between 4 and 6 mg/mL, with E. coli being the most sensitive to both fractions. Changes in the chemical composition after treatment of the crude fraction with a solution of calcium chloride led to a decrease in the content of sulfates and uronic acids and diminished antibacterial activity.\n

To date, despite the discovery of many sulfatase genes and the accumulation of data on numerous sulfated molecules, the number of characterized enzymes that are key players in sulfur metabolism remains extremely limited. While mammalian sulfatases are well studied due to their involvement in a wide range of normal and pathological biological processes, lower eukaryotic sulfatases, especially fungal sulfatases, have not been thoroughly investigated at the biochemical and structural level. In this paper, we describe the molecular cloning of Fusarium proliferatum sulfatase (F.p.Sulf-6His), its recombinant expression in Pichia pastoris as a soluble and active cytosolic enzyme and its detailed characterization. Gel filtration and native electrophoretic experiments showed that this recombinant enzyme exists as a tetramer in solution. The enzyme is thermo-sensitive, with an optimal temperature of 25°C. The optimal pH value for the hydrolysis of sulfate esters and stability of the enzyme was 6.0. Despite the absence of the post-translational modification of cysteine into Cα-formylglycine, the recombinant F.p.Sulf-6His has remarkably stable catalytic activity against p-nitrophenol sulfate, with kcat = 0.28 s-1 and Km = 2.45 mM, which indicates potential use in the desulfating processes. The currently proposed enzymatic mechanisms of sulfate ester hydrolysis do not explain the appearance of catalytic activity for the unmodified enzyme.

\n Sulfatases are a family of enzymes (sulfuric ester hydrolases, EC 3.1.6.-) that catalyze the hydrolysis of a wide array of sulfate esters. To date, despite the discovery of many sulfatase genes and the accumulation of data on numerous sulfated molecules, the number of characterized enzymes that are key players in sulfur metabolism remains extremely limited. While mammalian sulfatases are well studied due to their involvement in a wide range of normal and pathological biological processes, lower eukaryotic sulfatases, especially fungal sulfatases, have not been thoroughly investigated at the biochemical and structural level. In this paper, we describe the molecular cloning of Fusarium proliferatum sulfatase (F.p.Sulf-6His), its recombinant expression in Pichia pastoris as a soluble and active cytosolic enzyme and its detailed characterization. Gel filtration and native electrophoretic experiments showed that this recombinant enzyme exists as a tetramer in solution. The enzyme is thermo-sensitive, with an optimal temperature of 25°C. The optimal pH value for the hydrolysis of sulfate esters and stability of the enzyme was 6.0. Despite the absence of the post-translational modification of cysteine into Cα-formylglycine, the recombinant F.p.Sulf-6His has remarkably stable catalytic activity against p-nitrophenol sulfate, with kcat = 0.28 s-1 and Km = 2.45 mM, which indicates potential use in the desulfating processes. The currently proposed enzymatic mechanisms of sulfate ester hydrolysis do not explain the appearance of catalytic activity for the unmodified enzyme. According to the available models, the unmodified enzyme is not able to perform multiple catalytic acts; therefore, the enzymatic mechanism of sulfate esters hydrolysis remains to be fully elucidated.\n

Molecular modeling of the reaction stage preceding the formation of the pNP-digalactosides within the active site of the enzyme revealed amino acid residues which modification was expected to increase the efficiency of transglycosylation. Upon the site-directed mutagenesis to the predicted substitutions of the amino acid residues, genes encoding the wild type TmGalA and its mutants were expressed in E. coli, and the corresponding enzymes were isolated and tested for the presence of the transglycosylating activity in synthesis of different pNP-digalactosides. Three mutants, F328A, P402D, and G385L, were shown to markedly increase the total transglycosylation as compared to the wild type enzyme.

\n At high concentrations of p-nitrophenyl-α-D-galactopyranoside (pNPGal) as a substrate, its hydrolysis catalyzed by α-galactosidase from Thermotoga maritima (TmGalA) is accompanied by transglycosylation resulting in production of a mixture of (α1,2)-, (α1,3)-, and (α1,6)-p-nitrophenyl (pNP)-digalactosides. Molecular modeling of the reaction stage preceding the formation of the pNP-digalactosides within the active site of the enzyme revealed amino acid residues which modification was expected to increase the efficiency of transglycosylation. Upon the site-directed mutagenesis to the predicted substitutions of the amino acid residues, genes encoding the wild type TmGalA and its mutants were expressed in E. coli, and the corresponding enzymes were isolated and tested for the presence of the transglycosylating activity in synthesis of different pNP-digalactosides. Three mutants, F328A, P402D, and G385L, were shown to markedly increase the total transglycosylation as compared to the wild type enzyme. Moreover, the F328A mutant displayed an ability to produce a regio-isomer with the (α1,2)-bond at yield 16-times higher than the wild type TmGalA.\n

\n The 160 kDa alpha-mannosidase (E.C. 3.2.1.24) isolated from culture filtrate of Trichoderma reesei has wide aglycon specificity but cleaves the alpha1 –> 2 and alpha1 –> 3 mannosidic bonds with higher rate than alpha1 –> 6 bond and slowly hydrolyses yeast mannan and 1,6-alpha-mannan. The specific activity of the enzyme and rate constant in the reaction with p-nitrophenyl-alpha-D-mannopyranoside were 0.15 U/mg and 1.62 x 10(-4) microM/min/microg, respectively, at optimal pH 6.5. We have found that in vitro enzyme is able to cleave off 30% of total alpha-mannopyranosyl residues from N- and O-linked glycans of secreted glycoproteins. The activity of the alpha-mannosidase toward glycoproteins in vivo was studied comparing the structures of O- and N-linked glycans of glycoproteins isolated from the cultures growing with and without 1-deoxymannojirimycin, an inhibitor of alpha-mannosidases. Difference in structures of these glycans may be explained by postsecretory deglycosylation catalysed by the alpha-mannosidase.\n
