| 3.4.11.10 | additional information | preparation of C-terminally Lys-tagged aminopeptidase II, with either tri- or nona-lysines, and immobilization of the modified enzymes on carboxylated magnetic particles, method and evaluation of enzyme properties, overview. The carboxylated magnetic particles are prepared by the simple co-precipitation of Fe3+/Fe2+ in aqueous medium and then subsequently modified with adipic acid. The immobilized enzymes, especially BsAPII-Lys9, can be recovered magnetically and used repeatedly, thermal and storage stabilities of the immobilized BsAPII-Lys9 are greatly improved | Geobacillus stearothermophilus |
