Exoglucanase for BioSandwich

This is a modified version of BBa_K118022 for use with the BioSandwich protocol (RFC 81) of Edinburgh 2011.

When used to make fusion proteins, BioSandwich assembly uses an in-frame BglII site (formed by the last 2 bases of the RFC10 prefix and the first 4 bases at the start of this BioBrick) and an in-frame SpeI site (present in the RFC10 suffix). Because the SpeI site is out of frame, two bases ("TC") have been added at the end. When combined with the T at the start of the RFC10 suffix, they code for a serine residue and correct the frameshift.

The signal peptide of the exoglucanase (amino acids 1 - 42) has been removed, since this part is intended for fusion to INP or other display proteins.

A non-synonymous change (see figure) was accidentally introduced, probably by PCR. An aspartic acid residue has become a glycine.

Usage and Biology

This is an exoglucanase from Cellulomonas fimi. It degrades cellulose by chewing at the end of a cellulose chain to produce cellobiose sugar.
