Figure 7. Architectural models of A. cellulolyticus cellulosome systems. (A) Cell-bound cellulosome systems. (B) Cell-free cellulosome systems.

Confirmed cohesin–dockerin interactions (those interactions ∼2x above the background cutoff threshold) are indicated in the connectivity scheme. Color coding (yellow, green and red) of the modules, brackets, and arrows reflect the respective affinity profiles enumerated in the figure. Black circles, white circles, and black/white circles indicate modules studied in this work, in previous works, and in both this work and previous works, respectively.
