Abstract
In response to advances in proteomics research and the use of proteins in medical and biotechnological applications, recombinant protein production and the design of specific protein characteristics and functions has become a widely used technology. In this context, protein fusion tags have been developed as indispensable tools for protein expression, purification, and the design of functionalized surfaces or artificially bifunctional proteins. Here we summarize how positively or negatively charged polyionic fusion peptides with or without an additional cysteine can be used as protein tags for protein expression and purification, for matrix-assisted refolding of aggregated protein, and for coupling of proteins either to technologically relevant matrices or to other proteins. In this context we used cysteine-containing polyionic fusion peptides for the design of immunotoxins. In general, polyionic fusion tags can be considered as a multifunctional module in protein technology.

Abstract
The rapid advancement of genetic engineering has allowed to produce an impressive number of proteins on a scale which would not have been achieved by classical biotechnology. At the beginning of this development research was focussed on elucidating the mechanisms of protein overexpression. The appearance of inclusion bodies may illustrate the success. In the meantime, genetic engineering is not only expected to achieve overexpression, but to improve the whole process of protein production. For downstream processing of recombinant proteins, the synthesis of fusion proteins is of primary importance. Fusion with certain proteins or peptides may protect the target protein from proteolytic degradation and may alter its solubility. Intracellular proteins may be translocated by means of fusions with signal peptides. Affinity tags as fusion complements may render protein separation and purification highly selective. These methods as well as similar ones for improving the downstream processing of proteins will be discussed on the basis of recent literature.

Abstract
Host selection can be a strategy to simplify downstream processing for protein recovery. Advancing capabilities for using plants as hosts offers new host opportunities that have received only limited attention from a downstream processing perspective. Here, we investigated the potential of using a polycationic precipitating agent (polyethylenimine; PEI) to precipitate an acidic model protein (beta-glucuronidase; GUS) from aqueous plant extracts. To assess the potential of host selection to enhance the ease of recovery, the same procedure was applied to oilseed extracts of canola, corn (germ), and soy. For comparison, PEI precipitation of GUS was also evaluated from a crude bacterial fermentation broth. Two versions of the target protein were investigated--the wild-type enzyme (WTGUS) and a genetically engineered version containing 10 additional aspartates on each of the enzyme's four homologous subunits (GUSD10). It was found that canola was the most compatible expression host for use with this purification technique. GUS was completely precipitated from canola with the lowest dosage of PEI (30 mg PEI/g total protein), and over 80% of the initial WTGUS activity was recovered with 18-fold purification. Precipitation from soy gave yields over 90% for WTGUS but only 1.3-fold enrichment. Corn, although requiring the most PEI relative to total protein to precipitate (210 mg PEI/g total protein for 100% precipitation), gave intermediate results, with 81% recovery of WTGUS activity and a purification factor of 2.6. The addition of aspartate residues to the target protein did not enhance the selectivity of PEI precipitation in any of the systems tested. In fact, the additional charge reduced the ability to recover GUSD10 from the precipitate, resulting in lower yields and enrichment ratios compared to WTGUS. Compared to the bacterial host, plant systems provided lower polymer dosage requirements, higher yields of recoverable activity and greater purification factors.

Abstract
In this article, recent progress related to the use of different types of polypeptide fusion handles or 'tags' for the purification of recombinant proteins are critically discussed. In addition, novel aspects of the molecular cassette concept are elaborated, together with areas of potential application of these fundamental principles in molecular recognition. As evident from this review, the use of these concepts provides a powerful strategy for the high throughput isolation and purification of recombinant proteins and their derived domains, generated from functional genomic or zeomic studies, as part of the bioprocess technology leading to their commercial development, and in the study of molecular recognition phenomena per se. In addition, similar concepts can be exploited for high sensitivity analysis and detection, for the characterisation of protein bait/prey interactions at the molecular level, and for the immobilisation and directed orientation of proteins for use as biocatalysts/biosensors.

Abstract
The de novo design of a molecular adapter for directed association and covalent linkage of two polypeptides is presented. Using peptides containing charged amino acid residues and an additional cysteine residue (AlaCysLys(8) and AlaCysGlu(8)) we demonstrate that the electrostatic interaction promotes the association of two synthetic peptides and, subsequently, disulfide bond formation. The reaction depends on both the redox potential and on the ionic strength of the buffer. Varying the redox potential, the interaction of the peptides was quantified by a Delta G(0') of 6.6 +/- 0.2 kcal/mol. Heterodimerization of the peptides is highly specific, a competition of association by other cysteine containing compounds could not be observed. Two proteins comprising cysteine-containing polyionic fusion peptides, a modified Fab fragment and an alpha-glucosidase fusion, could be specifically conjugated by directed association and subsequent disulfide bond formation. Both proteins retain their functional characteristics within the bifunctional conjugate: enzymatic activity of the alpha-glucosidase and antigen-binding capacity of the Fab fragment are equivalent to the non-conjugated components.

Abstract
The chromatographic behaviour of recombinant human tumour necrosis factor beta (rhTNF-beta) (pI approximately 9.0) during cation-exchange chromatography at pH 7.5 is investigated. Without prior treatment of the Escherichia coli cell extract with polyethyleneimine (PEI), very little rhTNF-beta was bound to the column. However, upon addition of 5% PEI (100 microliters ml-1) to the cell lysate, rhTNF-beta was shown to bind to cation-exchange columns normally. TNF-beta was readily precipitated from the clarified cell extract by 20% ammonium sulphate, but ony ca. 25% of this precipitate could be re-solubilized for further purification. However, when 5% PEI was included in the solubilization buffer, the balance of the rhTNF-beta could be recovered. It is proposed that charge interaction between rhTNF-beta and nucleic acids in the cell extract is responsible for both of these anomalous phenomena, and that PEI (a cationic polyelectrolyte) was able to disrupt this interaction by displacing rhTNF-beta from the charge complex.

Abstract
The purification of a thermostable Caldocellum saccharolyticum beta-glucosidase expressed in Escherichia coli was investigated using heat precipitation of unclarified cell homogenates. Heat treatment at 70 degrees C was capable of purification with respect to cell debris, small particulates and the majority of cell protein, although E. coli proteins were even more efficiently removed at 80 degrees C and above. For thermostable proteins expressed in E. coli, a precipitation temperature of 80 degrees C or greater is recommended for optimal removal of contaminant proteins. In small-scale heating trials, heating rate was found to influence enzyme yield significantly. Losses were minimised when 'flash-heating' was employed. The successful single-step removal of particulates, labile protein and nucleic acids was achieved by simultaneous heat-treatment and polyethyleneimine addition, although the purification achieved was additive rather than synergistic.

Abstract
Poly(aspartic acid) tails of different lengths were fused to the glucoamylase (GA) of Aspergillus awamori by genetic engineering techniques. Tails consisting of 5, 7, and 10 aspartate residues were fused to the N-terminus of the full-length mature GA (aa 1-616) downstream from the intact leader peptide to produce fusion proteins designated GAND5, GAND7, and GAND10, respectively. Three fusion proteins with C-terminal tails were also constructed, designated GACD0, GACD5, and GACD10 (0, 5, and 10 aspartate residues, respectively). For the C-terminal fusion proteins, the tails were fused to a catalytically active but truncated form of GA (aa 1-484). All of the charged tails had the general sequence Met-Ala-Aspn-Tyr, where n = 0, 5, 7, or 10. The modified genes were expressed in the yeast Saccharomyces cerevisiae and the proteins secreted into the culture medium. The enzymes were subsequently purified by affinity chromatography. The specific activity of each purified enzyme was found to be comparable to the wild-type enzyme. The C-terminal tails did not interfere with expression, whereas decreased extracellular glucoamylase activities corresponding to increased tail length were found for the N-terminal fusion proteins. Amino-terminal amino acid sequence analysis of the purified GAND proteins confirmed the authenticity of the amino termini of the modified proteins and showed that both the leader peptidase and KEX2 protease cleavages had occurred faithfully. The increased net negative charge of the GAND and GACD proteins was indicated by both nondenaturing PAGE and isoelectric focusing.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
To obtain affinity adsorbents with good mechanical resistance, suitable for the purification of maltose-binding protein (MBP) from Escherichia coli and genetically engineered proteins fused to MBP, a series of supports were prepared by grafting amylose on to agarose by different chemistries. Their capacities for MBP and their abilities to be used at relatively high flow-rates were examined. Efficient supports were most conveniently prepared by coupling amylose to epoxy-activated agarose in an aqueous-organic mixture.

Abstract
Several fusion tail systems have been developed to promote efficient recovery and purification of recombinant proteins from crude cell extracts or culture media. In these systems, a target protein is genetically engineered to contain a C- or N-terminal polypeptide tail, which provides the biochemical basis for specificity in recovery and purification. Tails with a variety of characteristics have been used: (1) entire enzymes with affinity for immobilized substrates or inhibitors; (2) peptide-binding proteins with affinity to immunoglobulin G or albumin; (3) carbohydrate-binding proteins or domains; (4) a biotin-binding domain for in vivo biotination promoting affinity of the fusion protein to avidin or streptavidin; (5) antigenic epitopes with affinity to immobilized monoclonal antibodies; (6) charged amino acids for use in charge-based recovery methods; (7) poly(His) residues for recovery by immobilized metal affinity chromatography; and (8) other poly(amino acid)s, with binding specificities based on properties of the amino acid side chain. Fusion tails are useful at the lab scale and have potential for enhancing recovery using economical recovery methods that are easily scaled up for industrial downstream processing. Fusion tails can be used to promote secretion of target proteins and can also provide useful assay tags based on enzymatic activity or antibody binding. Many fusion tails do not interfere with the biological activity of the target protein and in some cases have been shown to stabilize it. Nevertheless, for the purification of authentic proteins a site for specific cleavage is often included, allowing removal of the tail after recovery.
