化学生物学面临的开放挑战之一是确定在中性pH值下以大速率常数进行的反应。如此处所示,在没有催化剂的情况下,二醛在中性pH值下与O-烷基羟胺的反应速率为500 M -1 s -1。这些结合的关键是异常稳定的环状中间体,该中间体最终会脱水以生成肟。概述了该方法的范围和局限性,以及其在生物偶联中的应用以及有助于在低底物浓度下进一步发展与烷基羟胺反应的机理的解释。

The reversible phosphorylation of proteins is one of the most important mechanisms for the regulation of signal transduction cascades. Recently, there has been substantial progress made in the identification of new phosphoproteins and phosphorylation sites. Unfortunately, there are very few methods available that allow this information to be used to identify the upstream kinase responsible for the phosphorylation event. Herein, we describe a new method that allows the cross-linking of a substrate of interest to its upstream kinase. This method relies upon a novel, mechanism-based cross-linker and the replacement of the phosphorylated residue with a cysteine residue. The application of this method to a number of kinase-peptide substrate pairs is described.
