Motion and Scheme (IMAGE) National Institutes of Natural Sciences Caption SmChiA shows 1-nm forward, backward, and recovery steps of motion (left). The ratio of catalysis and backward step calculated from time constants were 86 percent and 14 percent, respectively, indicating fast catalysis rectify the Brownian motion along chitin chain (right).
