    <dcterms:abstract><![CDATA[Among the different methods for obtaining immobilized biocatalysts, those based on thioldisulfide exchange reactions are unique because, simultaneously, they show a stable covalent bond and the possibility of eluting the protein by reduction when the enzymatic activity decays. The adsorbent can thus be reloaded. In this paper we report the use of the recently developed thiolreactive adsorbent thiolsulfonate-agarose, for the immobilization of sweet potato &beta;-amylase. Since native, &beta;-amylase thiol groups were not reactive towards the adsorbent, the enzyme was provided with &lsquo;de novo&rsquo; thiol groups by reaction with the heterobifunctional reagent N-succinimidyl-3- (2-pyridyldithio)propionate (SPDP). When the SPDP/&beta;-amylase molar ratio was changed between 3 and 100, up to sixteen exposed thiol groups per mol of enzyme were introduced. This was achieved without affecting the amylolytic activity. The immobilization yield for the intermediate thiolation level was 98%. However, only 19% of the applied enzyme activity was found in the gel suspension. Comparative studies were made on thiolsulfonate-agarose and on a commercial thiol-activated adsorbent (2-pyridyldisulfide-agarose). The immobilization of the thiolated enzyme through reversible disulfide bonds on both adsorbents showed similar results. A close analysis reveals that immobilization of proteins on thiolsulfonate-agarose is a very promising technique.]]></dcterms:abstract>

    <dcterms:abstract><![CDATA[The behaviour of wheat &beta;-amylase from crude extracts in chromatography on agarose gels substituted with different ligand types was investigated. The enzyme displayed high salt promoted adsorption onto thiophilic gels provided with sulfone-thioether and 2-thiopyridine ligands. Quantitative recovery of the enzyme was easily accomplished by elution with buffer in the absence of Na2SO4. The 3-(2-pyridylthio)-2-hydroxypropylagarose (PyS-gel) also allowed elimination of pigments present in the wheat extract. These pigments showed no adsorption onto the gel, thus regeneration is easily achieved, allowing its re-use. The enzyme also displayed strong salt-dependent adsorption onto adsorbents provided with pyridyldisulfide moieties, but in this case enzyme binding was due to its thiol content since elution was achieved mainly through reduction with DTT. When the enzyme was chromatographed on a series of hydrophobic alkyl ligands in the presence of 0.5 M sodium sulphate, it was partially adsorbed on pentylagarose and quantitatively adsorbed on hexyl-agarose, elution being easily performed by sodium sulphate-free buffer. This behaviour was markedly different from that towards phenyl-Sepharose, to which the enzyme was strongly adsorbed and which required much more drastic elution conditions.]]></dcterms:abstract>
