    • The present invention relates to a process for the identification of a kinase substrate specificity by using a peptide library. More particulary, the present invention is directed to a process for indent ifying a kinase substrate specificity, comprising: i ) linking a plurality of peptides, having a same amino acid sequence, to the surface of a solid support resin to obtain a peptide library which has peptides, with the same amino acid sequence, on the surface of the solid support resin; ii) repeating the step i ) with changing the amino acid sequence to give a random mixture of peptide libraries, wherein each solid suppot resin has peptides with a same amino acid sequence, however the amino acid sequence liked to each solid support is different from one another," iii) phosphorylating selectively a specific amino acid of a peptide which has a certain amino acid sequence by reacting the random mixture of the peptide libraries with a kinase, to give a phosphorylated peptide library; iv) reacting the phosphorylated peptide library with an antibody which is conjugated with one of a phosphatase and a peroxidase and binds selectively to a phosphorylated amino acid, followed by the addition of a substrate selectively acting on the thus prepared reaction mixture; v) selecting a solid support resin which has a peptide library of which property has been changed, by detecting the change of property due to the reaction of the sbustrate with one of the phosphatase and the peroxidase; and vi) separating a peptide from the selected solid support resin followed by analysing a sequece of the separated peptide.
    • 本发明涉及通过使用肽文库鉴定激酶底物特异性的方法。 更具体地,本发明涉及一种用于缩进激酶底物特异性的方法,其包括:i)将具有相同氨基酸序列的多个肽连接到固体支持树脂的表面,以获得肽文库, 在固体支持树脂的表面上具有相同氨基酸序列的肽; ii)通过改变氨基酸序列来重复步骤i),得到肽文库的无规混合物,其中每个固体支素树脂具有相同氨基酸序列的肽,然而对于每种固体支持物所喜欢的氨基酸序列不同于 另一个,“iii)通过使肽文库的无规混合物与激酶反应,使具有特定氨基酸序列的肽的特定氨基酸磷酸化,得到磷酸化肽文库; iv)使磷酸化肽文库与 抗体,其与磷酸酶和过氧化物酶之一缀合,并且与磷酸化氨基酸选择性结合,然后加入选择性地作用在如此制备的反应混合物上的底物; v)选择固体支持树脂,其具有肽文库 通过检测由于sbustrate与磷酸酶和过氧化物之一的反应引起的性质变化,该性质已经改变 Ë; 和vi)从所选择的固体支持树脂中分离肽,然后分析分离的肽的片段。
