FIG. 1.

Schematic representation of expression cassettes, encoded gene products, and identified amino acid residues at randomized positions in the engineered CBD variants. (A and B) Expression cassettes of the different expression vectors designed for surface display on S. carnosus, shown with their encoded gene products illustrated as anchored to the staphylococcal cell wall. The names of the constructed vectors are given below the expression cassettes, and the molecular masses of the encoded proteins are indicated together with the abbreviated names of the recombinant staphylococci. (C) Amino acid sequences of the wild-type and engineered CBD at the randomized positions.
