  usually an amino acid or a peptide. In order to investigate which moieties of the donor substrate are necessary for recognition by GGT, the structure of the well-recognized substrate L-gamma-glutamyl-p-nitroanilide was modified. Several activated esters and their amide derivatives were synthesized and used as substrates. Kinetic (K(m) and V(max)) and inhibition constants (K(i)) were measured and reveal

  涉及许多生理过程的酶γ-谷氨酰转肽酶（GGT）催化γ-谷氨酰基从供体底物向酰基受体底物（通常是氨基酸或肽）的转移。为了研究供体底物的哪​​些部分对于通过GGT识别是必需的，对公认的底物L-γ-谷氨酰基-对硝基苯胺的结构进行了修饰。合成了几种活化的酯及其酰胺衍生物，并用作底物。测量了动力学（K（m）和V（max））和抑制常数（K（i）），结果表明，几乎整个γ-谷氨酰基部分对于识别供体底物的结合位点都是必需的。

  An acrylamide derivative of general formula (I) is used to prepare a polymer or copolymer: wherein R1 represents a hydrogen atom, a straight-chain or branched alkyl group containing 1 to 4 carbon atoms or a C3-6 cycloalkyl group, R?2 and R3¿ each independently represent an alkylene group containing 1 to 6 carbon atoms or R?2 and R3¿ may be combined to form a ring, X represents a hydrogen atom, an amino group, a hydroxyl group, a halogen atom, a carboxyl group or a -COOR4 group wherein R4 represents a C1-6 straight-chain or branched alkyl, C3-6 cycloalkyl, phenyl, substituted phenyl, benzyl or substituted benzyl group, and Y represents an amino group, a halogen atom, a carboxyl group or a -COOR4 group wherein R4 represents a C1-6 straight-chain or branched alkyl, C3-6 cycloalkyl, phenyl, substituted phenyl, benzyl or substituted benzyl group. The thus obtained polymer or copolymer is a polymer or hydrogel incorporating many functional groups while maintaining the sensitive temperature response.
