Provided herein are methods for enhancing enzymatic activity using certain polymers that may be optionally attached to an enzyme. The polymers may be thermally-responsive polymers, including poly N-isopropylacrylamide or poly N-isopropylmethacrylamide. The polymer may also be a copolymer with at least two different monomer residues. The monomer residues may have a structure of formula (I):
wherein R

, R
A
and R
B
are as described herein. Examples of such monomer residues may include N-isopropylacrylamide (NIPAm) or N-isopropylmethacrylamide (NIPMa). The polymer may include additional monomer residues, such as aminooxy-bearing methacrylamide monomer residues that can be modified to vary the lower critical solution temperature (LCST) of the polymer.
本文提供了一种利用某些聚合物增强酶活性的方法,这些聚合物可以选择性地附着在酶上。这些聚合物可以是热响应性聚合物,包括聚N-异丙基丙烯酰胺或聚N-异丙基甲基丙烯酰胺。该聚合物也可以是至少含有两种不同单体残基的共聚物。这些单体残基可能具有以下结构(I)的结构:其中R1,RA和RB如本文所述。此类单体残基的示例可能包括N-异丙基丙烯酰胺(NIPAm)或N-异丙基甲基丙烯酰胺(NIPMa)。该聚合物可能包括额外的单体残基,例如氨氧基甲基丙烯酰胺单体残基,可以被修改以改变聚合物的临界溶解温度(LCST)。
