CBDcenA+Linker, RFC 25 standard

Cellulose binding domain (CBD) of Endoglucanase A (cenA) from Cellulomonas fimi with an endogenous C-terminal linker. The part is in Freiburg format (RFC 25) for ease of use in protein fusions.

Usage and Biology

The cellulose binding domain region occurs at the N-terminus of the cenA gene ([http://www.uniprot.org/uniprot/P07984 UniProt P07984]) and is from the [http://www.cazy.org/CBM2.html CBM family 2].

The linker sequence (PTTSPTPTPTPTTPTPTPTPTPTPTPTVTP) is Pro-Thr box which has an extended conformation and acts as a hinge region (1). The endoglucanase CBDcenA has 50% homology to the exoglucanase CBDcex (BBa_K863101) and the linker is highly conserved in both, but the order of the catalytic, linker and cellulose-binding regions is reversed (2). It has been shown that CBDcenA has the highest binding affinity for crystalline cellulose out of the C. fimi CBDs (3).
