对于缺乏同源亲和标记的酶设计基于活性的探针,对亲电体的蛋白质组反应性的洞察是至关重要的。在这里,我们显示了不同类别的碳亲电体在蛋白质组中表现出明显不同的氨基酸标记图谱,范围从与半胱氨酸的选择性反应到与几种氨基酸的加合物。这些数据指定了具有受限和允许反应性特征的亲电化学类型,以指导下一代功能蛋白质组探针的设计。
Insights into the proteome reactivity of electrophiles are crucial for designing activity-based probes for enzymes lacking cognate affinity labels. Here, we show that different classes of carbon electrophiles exhibit markedly distinct amino acid labeling profiles in proteomes, ranging from selective reactivity with cysteine to adducts with several amino acids. These data specify electrophilic chemotypes with restricted and permissive reactivity profiles to guide the design of next-generation functional proteomics probes.
