Schematic diagrams of a biomimetic cellulosome and a biomimetic operon. a Schematic representation of a biomimetic cellulosome and assembly of cellulosomal subunits on the cell surface. The cell-surface anchor (sdbA, shown in blue) is attached on the cell membrane. The scaffolding protein (CipA, shown in yellow) is composed primarily of nine copies of specific Type I cohesin and Type III carbohydrate-binding modules (CBM). b Construction of biomimetic polycistronic operons, Type I and Type II in pGETS 118 vector, restriction enzymes were given in red color. c The confirmation of gene assembly pattern by EcoRI Restriction digestion
