Design Notes

This part is based on the double cellulose-binding domain construct (CBDcbh2-linker-CBDcbh1) synthesised and characterised by Linder et al (1) who found that this double CBD had higher affinity for cellulose than either of the two CBDs on their own. The main difference is that our part contains an additional linker sequence on the N-terminus of the protein.

The two CBDs are from the fungus T. reesei (Hypocrea jecorina) Exocellobiohydrolase (Exoglucanase) I (cbh1), uniprot ID P62694; and Exocellobiohydrolase (Exoglucanase) II, uniprot ID P07987 (cbh2); with a linker peptide between the two CBDs and at the N-terminus of the protein. Both linkers are the same amino acid sequence and are based on the endogenous linker sequences that exists in cbh1 and cbh2 genes. The linker sequence is PGANPPGTTTTSRPATTTGSSPGP which is the same as used by Linder et al (1). The first three amino acids are from the cbh2 endogenous linker, and the rest is from the cbh1 endogenous linker. CBDcbh1 is placed C-terminal to CBDcbh2 because naturally CBDcbh1 is a C-terminal domain and CBDcbh2 is an N-terminal domain. Both CBDs are from the CBM family 1. The precise location of the CBD within the cbh genes was slightly different according to the uniprot annotations and the sequence used by Linder et al (1); we chose to use the sequence from the paper since the protein was expressed and characterised successfully.
