The invention provides methods and systems by which enzymes can be modified to improve solubility, catalytic activity, recoverability, and recyclability. The enzyme may be modified with a thermosensitive copolymer to form an enzyme-polymer conjugate that exhibits upper critical solution temperature (UCST) and/or lower critical solution temperature (LCST)-type behavior in an organic solvent, ionic liquid, or other solvent. Methods and systems of the invention facilitate the use of enzymes as biocatalysts in solvents.
本发明提供了对酶进行改性以提高其溶解性、催化活性、可回收性和可再循环性的方法和系统。可以用热敏共聚物对酶进行改性,以形成酶-聚合物共轭物,该共轭物在有机溶剂、
离子液体或其他溶剂中表现出上临界溶液温度(UCST)和/或下临界溶液温度(LCST)型行为。本发明的方法和系统有助于在溶剂中使用酶作为
生物催化剂。
