Distributions of the duration time on cellulose for Intact (left), CD (center left), CBM-linker (center right), and CBM (right) fitted with double exponential decay functions. For Intact, kofffast was 1.1 s−1 (70%), and koffslow was 0.10 s−1 (30%). For CD, kofffast was 1.5 s−1 (72%), and koffslow was 0.16 s−1 (28%). For CBM-linker, kofffast was 2.6 s−1 (65%), and koffslow was 0.14 s−1 (35%). For CBM, kofffast was 2.3 s−1 (70%), and koffslow was 0.083 s−1 (30%). The number of events was 757, 403, 614, and 756 for Intact, CD, CBM-linker, and CBM, respectively. The bin widths of the distributions were 0.2 s.
