Chain length distributions of oligosaccharides in glycogen extracted from the six E. coli DH5α strains. A. Chain length distributions of isoamylase-debranched glycogen, which are expressed as molar percentage (%) in terms of oligosaccharide chain length. B. Difference plot generated by subtracting the molar percentage of the respective WT oligosaccharide DP from the corresponding glgBΔ90, glgBΔ180, glgBΔ270, and glgBΔ369 molar percentages. The experiment was performed twice independently with two repeats for each replicate.
