Additional file 2. SDS-PAGE summary of all recombinantly expressed dockerin type I containing proteins used in this study (60 different components of C. thermocellum cellulosome). Each protein is shown after the purification process, including the final heat precipitation step. Enzyme names and Clo1313 numbers are shown above the corresponding SDS-PAGE picture. Molecular weight standards are depicted in kDa. Proteins marked with asterisks are truncated versions of the original protein.
