Carbonic anhydrases (CAs) represent a group of enzymes that catalyse important reactions of carbon dioxide hydration and dehydration, a reaction crucial to many biological processes and environmental biotechnology. In this study we successfully constructed a thermostable fusion enzyme composed of the Sulfurihydrogenibium azorense carbonic anhydrase (Saz_CA), the fastest CA discovered to date, and the chitin binding domain (ChBD) of chitinase from Bacillus circulans. Introduction of ChBD to the Saz_CA had no major impact on the effect of ions or inhibitors on the enzymatic activity. The fusion protein exhibited no negative effects up to 60 °C, whilst the fusion partner appears to protect the enzyme from negative effects of magnesium. The prepared biocatalyst appears to be thermally activated at 60 °C and could be partially purified with heat treatment. Immobilisation attempts on different kinds of chitin-based support results have shown that the fusion enzyme preferentially binds to a cheap, untreated chitin with a large crystallinity index over more processed forms of chitin. It suggests significant potential economic benefits for large-scale deployment of immobilised CA technologies such as CO2 utilisation or mineralisation.

Crystals of an intact GST–estrogen receptor hormone binding domain fusion protein have been grown from solutions of MPD. The crystals grew as clusters of thin plates and needles of maximum dimensions 100 × 20 × 1 µm but were unsuitable for X-ray diffraction analysis. However, examination by electron microscopy shows an ordered lattice in which the protein molecules are clearly visible. Image analysis of electron micrographs of the protein crystals revealed electron stain-excluding density which showed a two-domain trimeric structure in projection, with each molecule of dimensions 12.0 × 5.0 nm diameter. The use of GST-fusion proteins in crystallization are discussed.
