Abstract
A glycosidase of the basidiomycete Bjerkandera adusta (BadGluc) was found in screenings to possess a strong decolorizing ability towards malvidin-3-galactoside, an anthocyanin abundant in various berry fruits. The BadGluc was purified from the culture supernatant via FPLC, and the corresponding gene was identified which showed low similarity to other characterized glucosidases. Scanning the primary sequence with PROSITE no active site motif was detected. Eventually, a specific 18 aa consensus pattern was identified manually. The active site motif possessed an undescribed sequence which was only found in a few hypothetical proteins. The corresponding gene was cloned and expressed in Pichia pastoris GS115 yielding activities up to 100 U/L using 4-nitrophenyl-β-d-glucopyranoside (pNPG) as substrate. The enzyme possessed a good temperature (70% after 1 h at 50°C) and pH stability (70% between pH 2 and 7.5), and preferably catalysed the hydrolysis of delphinidin-3-glucoside and cyanidin-3-glucoside, regardless of the position of the terminal Hexa-His tag. This novel glucosidase worked in aqueous solution as well as on pre-stained fabrics making it the first known candidate anthocyanase for applications in the detergent and food industries.

Abstract
Immobilized metal ion affinity chromatography (IMAC) is widely used for the purification of many different His6-tagged recombinant proteins. On the one hand, it is a powerful technique but on the other hand it has its disadvantages. In this report, we present the development of a unique ssDNA aptamer for the purification of His3-tagged recombinant proteins. Our study shows that stability of the His3-tag/H3T aptamer complex can be controlled by the sodium ion concentration. Based on this feature, we demonstrate that H3T aptamer resin was successfully employed for the purification of three out of four tested His3-tagged recombinant proteins from an E. coli total protein extract using imidazole-free buffers. Finally, we show that the purity of His3-tagged proteins is superior when purified with the help of the H3T aptamer in comparison with Ni-NTA resin.

Abstract
Decorin is a multifunctional small leucine-rich proteoglycan involved in the regulation of collagen fibrillogenesis. In patients with a variant of Ehlers-Danlos syndrome, about half of the secreted decorin lacks the single glycosaminoglycan side chain. Notably, these patients have a skin-fragility phenotype that resembles that of decorin null mice. In this study, we investigated the role of glycanated and unglycanated decorin on collagen fibrillogenesis. Glycosaminoglycan-free decorin, generated by mutating Ser4 of the mature protein core into Ala (DCN-S4A), showed reduced inhibition of fibrillogenesis compared with the decorin proteoglycan. Interestingly, using a 3D matrix generated by decorin-null fibroblasts, an increase in fibril diameter was found after the addition of decorin, and even greater effects were observed with DCN-S4A. To avoid potential side effects of artificial tags, adenoviruses containing decorin and DCN-S4A were used to transduce decorin-null fibroblasts prior to matrix formation. Both molecules were efficiently incorporated into the matrix, with no changes in collagen composition and network formation, or altered expression of the related proteoglycan biglycan. Both decorin and DCN-S4A mutants increased the collagen fibril diameter, with the latter showing the most prominent effects. These data show that at early stages of fibrillogenesis, the glycosaminoglycan chain of decorin has a reducing effect on collagen fibril diameter.

Abstract
Affinity tags are highly efficient tools for protein purification. They allow the purification of virtually any protein without any prior knowledge of its biochemical properties. The use of affinity tags has therefore become widespread in several areas of research e.g., high throughput expression studies aimed at finding a biological function to large numbers of yet uncharacterized proteins. In some cases, the presence of the affinity tag in the recombinant protein is unwanted or may represent a disadvantage for the projected application of the protein, like for clinical use. Therefore, an increasing number of approaches are available at present that are designed for the removal of the affinity tag from the recombinant protein. Most of these methods employ recombinant endoproteases that recognize a specific sequence. These process enzymes can subsequently be removed from the process by affinity purification, since they also include a tag. Here, a survey of the most common affinity tags and the current methods for tag removal is presented, with special emphasis on the removal of N-terminal histidine tags using TAGZyme, a system based on exopeptidase cleavage. In the quest to reduce the significant costs associated with protein purification at large scale, relevant aspects involved in the development of downstream processes for pharmaceutical protein production that incorporate a tag removal step are also discussed. A comparison of the yield of standard vs. affinity purification together with an example of tag removal using TAGZyme is also included.

Abstract
Absence of sialylation on recombinant glycoproteins compromises their efficacy as therapeutic agents, as it results in rapid clearance from the human bloodstream. To circumvent this, several strategies are followed, including the implementation of a post-secretion glycosylation step. In this paper we describe the engineering of yeast cells expressing active surface exposed Trypanosoma cruzi trans-sialidase (TS) fused to the yeast Aga2 protein, and the use of this yeast in the sialylation of synthetic oligosaccharides. In an attempt to improve overall protein accessibility on the yeast surface, we abolished hyperglycosylation on the yeast cell wall proteins. This was achieved by disrupting the OCH1 gene of the TS surface expressing strain, which resulted in increased enzymatic activity. Using a fluorescence-based activity assay and DSA-FACE structural analysis, we obtained almost complete conversion to a fully sialylated acceptor, whereas in the wild type situation this conversion was only partial. Increasing protein accessibility on the yeast surface by modifying the glycosylation content thus proved to be a valuable approach in increasing the cell wall associated activity of an immobilised enzyme, hence resulting in a more effective biocatalyst system.

Abstract
The lgtB genes that encode beta-1,4-galactosyltransferases from Neisseria meningitidis ATCC 13102 and gonorrhoeae ATCC 31151 were isolated by a polymerase chain reaction using the pfu DNA polymerase. They were expressed under the control of lac and T7 promoters in Escherichia coli M15 and BL21 (DE3). Although the genes were efficiently expressed in E. coli M15 at 37 degrees C (33 kDa), most of the beta-1,4-galactosyltransferases that were produced were insoluble and proteolysed into enzymatically inactive polypeptides that lacked C-terminal residues (29.5 kDa and 28 kDa) during the purification steps. When the temperature of the cell growth was lowered to 25 degrees C, however, the solubility of the beta-1,4-galactosyltransferases increased substantially. A stable N-terminal his-tagged recombinant enzyme preparation could be achieved with E. coli BL21 (DE3) that expressed lgtB. Therefore, the cloned beta-1,4-galactosyltransferases were expressed under the control of the T7 promoter in E. coli BL21 (DE3), mostly to the soluble form at 25 degrees C. The proteins were easily purified to homogeneity by column chromatography using Ni-NTA resin, and were found to be active. The galactosyltransferases exhibited pH optimum at 6.5-7.0, and had an essential requirement for the Mn(+2) ions for its action. The Mg(+2) and Ca(+2) ions showed about half of the galactosyltransferase activities with the Mn(+2) ion. In the presence of the Fe(+2) ion, partial activation was observed with the beta-1,4-galactosyltransferase from N. meningitidis (64% of the enzyme activity with the Mn(+2) ion), but not from N. gonorrhoeae. On the other hand, the N(+2), Zn(+2), and Cu(+2) ions could not activate the beta-1,4- galactosyltransferase activity. The inhibited enzyme activity with the Ni(+2) ion was partially recovered with the Mn(+2) ion, but in the presence of the Fe(+2), Zn(+2), and Cu(+2) ions, the Mn(+2) ion could not activate the enzyme activities. Also, the beta-1,4-galactosyltransferase activity was 1.5-fold stimulated with the non-ionic detergent Triton X-100 (0.1-5 percent).

Abstract
Equine herpesvirus 1 glycoprotein D (EHV-1 gD) has been shown in mouse models and in the natural host to have potential as a subunit vaccine, using various expression systems that included Escherichia coli, baculovirus and plasmid DNA. With the aim of producing secreted recombinant protein, we have cloned and expressed EHV-1 gD, lacking its native signal sequence and C-terminal transmembrane region, into the methylotrophic yeast Pichia pastoris. The truncated glycoprotein D (gD) gene was placed under the control of the methanol inducible alcohol oxidase 1 promoter and directed for secretion with the Saccharomyces cerevisiae alpha-factor prepro secretion signal. SDS-PAGE and Western blot analysis of culture supernatant fluid 24 h after induction revealed gD-specific protein products between 40 and 200 kDa. After treatment with PNGase F and Endo H, three predominant bands of 34, 45 and 48 kDa were detected, confirming high mannose N-linked glycosylation of Pichia-expressed gD (Pic-gD). N-terminal sequence analysis of PNGase F-treated affinity-purified protein showed that the native signal cleavage site of gD was being recognised by P. pastoris and the 34 kDa band could be explained by internal proteolytic cleavage effected by a putative Kex2-like protease. Pic-gD, when used in a DNA prime/protein boost inoculation schedule, induced high EHV-1 ELISA and virus neutralizing antibodies and provided protection from challenge infection in BALB/c mice.

Abstract
The generation of antibodies is one of the first requirements in the characterisation of a newly cloned protein. However, this requires expression and purification of the protein in sufficient yield and purity for immunisation of animals and screening of fusion wells. Even with the development of highly efficient protocols based upon incorporation of specific peptide tags, this can be a tedious and time-consuming process. In an effort to improve the speed and efficiency of obtaining antibodies reactive with newly cloned proteins we have developed an approach based upon the expression of the protein at high level in cell lines originating from the species to be used for immunisation. To illustrate this approach we describe the generation of antibodies against two recently cloned proteins that are normally expressed at the membrane, the rat and mouse analogues of human decay accelerating factor (DAF; CD55). However, the strategy is applicable not only to membrane proteins but also to other proteins which can be expressed on the cell membrane by incorporating at the carboxy terminus the signal sequence for glycosyl phosphatidylinositol (GPI) anchor addition derived from DAF or another GPI-anchored protein. The strategy also permits rapid and efficient screening using flow cytometry on expressing cells.

Abstract
Glycosyltransferases are increasingly being used for in vitro synthesis of oligosaccharides. Since these enzymes are difficult to purify from natural sources, expression systems for soluble forms of the recombinant enzymes have been developed. This review focuses on the current state of development of yeast expression systems. Two yeast species have mainly been used, i.e. Saccharomyces cerevisiae and Pichia pastoris. Safety and ease of fermentation are well recognized for S. cerevisiae as a biotechnological expression system; however, even soluble forms of recombinant glycosyltransferases are not secreted. In some cases, hyperglycosylation may occur. P. pastoris, by contrast, secrete soluble orthoglycosylated forms to the supernatant where they can be recovered in a highly purified form. The review also covers some basic features of yeast fermentation and describes in some detail those glycosyltransferases that have successfully been expressed in yeasts. These include beta1,4galactosyltransferase, alpha2,6sialyltransferase, alpha2,3sialyltransferase, alpha1,3fucosyltransferase III and VI and alpha1,2mannosyltransferase. Current efforts in introducing glycosylation systems of higher eukaryotes into yeasts are briefly addressed.
