FIG 1 .

Schematic representation of the recombinant proteins used in this study. The source of the representative module (see key) is indicated as follows: light gray, T. fusca; green, R. flavefaciens; red, C. thermocellum; lavender, A. cellulolyticus; and yellow, B. cellulosolvens. In the shorthand notation for the engineered enzymes, the numbers 10, 11, and 43 refer to the corresponding GH family (GH10, GH11, and GH43) of the catalytic module; uppercase letters (B, F, T, and A) indicate the source of the cohesin module, and lowercase italic letters (b, f, t, and a) indicate the source of the dockerin module: B. cellulosolvens, R. flavefaciens, C. thermocellum, and A. cellulolyticus, respectively.
