preparation example Construction

[0092] They can be prepared, for example, by transforming a DNA structure into a host cell. The DNA structure contains at least one fragment of the DNA encoding the cellulose binding domain. With or without a linker, it can interact with the DNA encoding the beneficial enzyme. The sequences are linked and the transformed host cell is grown to express the fused gene. A related but non-limiting type of recombinant product (hybrid enzyme) obtained in this respect is usually called a "fusion protein" in the art, which can be described by one of the following general formulas:

[0093] A-CBD-MR-X-B

[0094] A-X-MR-CBD-B

[0095] In the latter formula, CBD is an amino acid sequence containing at least the cellulose binding domain (CBD) itself.

[0096] The MR (middle region; connecting region) may be a bond, comprising 1 to about 100 amino acid residues, particularly a linker of 2-40 amino acid residues, for example, 2-15 amino acid residues. MR can be predominantly and additionally non...
