The invention relates to a method for determining the substrate specificity of an enzymatic activity comprising the following steps: providing an assembly comprising a plurality of amino acid sequences on a planar surface of a support material, whereby the amino acids are directionally immobilised; contacting and/or incubating of an enzymatic activity with the assembly; and detection of a reaction between one of the amino acid sequences that are immobilised on the assembly and the enzymatic activity. According to the invention, during the reaction of the enzymatic activity with the assembly, a change in the molecular weight of at least one of the amino acid sequences takes place.
本发明涉及一种确定酶活性底物特异性的方法,包括以下步骤:在支撑材料的平面表面上提供包含多个
氨基酸序列的组装体,其中
氨基酸被定向固定;将酶活性与组装体接触和/或孵育;检测组装体上定向固定的
氨基酸序列之一与酶活性之间的反应。根据本发明,在酶活性与组装体反应期间,至少一个
氨基酸序列的分子量发生变化。
