Abstract
A gene fusion construction encoding a protein of interest and the chitin binding domain of a chitinase enzyme and the encoded fusion protein, which is the protein of interest and a protein capable of binding chitin. A plasmid vector containing the gene fusion construction is also described. The vector is used to transform host cells, which produce and secrete the recombinant fusion protein. The fusion protein is isolated by binding to chitin through its chitin-binding domain. The present method uses chitin to bind the fusion protein through its chitin-binding domain, and thereby allows immobilization and/or purification of the protein of interest, using known techniques.
