F ure 6. Distribution of modified AOT-coated starch nanoparticles within Novozym 435 as observed by Infrared Microscopy (IRMS). (A) Control spectra of pure starch nanoparticles (top) and unreacted Novozym beads (bottom). Spectral peaks unique to the Novozym, CAL-B, and starch are highlighted in gray, (B) Distribution of Novozym polymer MMA) in the bead cross-section, (C) Distribution of CALrB enzyme in the bead cross-section, (D) Distribution of starch nanoparticles in the bead cross-section. 

We are grateful to the members of the NSF I/UCRC for Biocatalysis and Bioprocessing of Macromolecules for their financial support, encouragement, and stimulating discussions. We acknowledge the generous gift of enzyme from Novozymes, and Ecosynthetix for the starch nanoparticles.

In addition to the synthesis of polysaccharides, the transglucosylation activity of GH family 13 amylosucrase from N. polysaccharea has been employed to modify amylo-polysaccharides, underlying the interest of this enzyme for the design of novel thickening agents, resistant starches, and original carbohydrate-based dendritic nanoparticles [73, 74].
