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.
本文报道了直链淀粉接枝纤维素的化学酶法合成。通过还原胺化将麦芽七糖化学引入到胺官能化纤维素中，以制备麦芽七糖接枝纤维素。然后，在纤维素衍生物上从接枝链末端进行磷酸化酶催化的1-磷酸葡萄糖的酶促聚合反应，得到直链淀粉接枝纤维素。所获得的材料显示出能形成凝胶和薄膜。对材料进行了干湿循环重复操作。
