From: Cellulosomics of the cellulolytic thermophile Clostridium clariflavum
Comparative sequence logos of the C. clariflavum and A. cellulolyticus dockerin modules. Amino acid conservation of the type I dockerin repeat sequences was performed by a logo, created using WebLogo (see Methods) based on 74 type I dockerin sequences of C. clariflavum and 138 of A. cellulolyticus. The top logo of each represents the first dockerin sequence repeat and the bottom logo represents the second dockerin repeat. Calcium-binding residues are highlighted in light blue, and the presumed recognition residues responsible for cohesin-dockerin interactions are highlighted in yellow.
