Abstract

This paper reports the chemoenzymatic synthesis of an amylose‐grafted cellulose. A maltoheptaose was chemically introduced to the amine‐functionalized cellulose by reductive amination to produce the maltoheptaose‐grafted cellulose. Then, the phosphorylase‐catalyzed enzymatic polymerization of glucose 1‐phosphate from the graft‐chain ends on the cellulose derivative was performed, giving the amylose‐grafted cellulose. The obtained material is shown to form gels and films. The dry and wet cycles of the materials were repeated.

## Abstract An amylose‐grafted chitosan has been synthesized by a chemoenzymatic method according to the following two reactions. First, maltoheptaose is introduced to chitosan by a reductive amination using sodium cyanotrihydroborate in a mixed solvent of 1.0 mol · L^−1^ aqueous acetic acid and me
