Benchmarking cleavable biotin tags for site-centric chemoproteomics


ABSTRACT: the performance of five common cleavable biotin linkers are assessed parallelly by using commercially available thiol-reactive probe IPM (2-iodo-N-(prop-2-yn-1-yl)acetamide) in profiling cysteinome

Click chemistry─specifically the copper-catalyzed azide-alkyne cycloaddition─has enabled the development of a wide range of chemical probes to analyze subsets of the functional proteome. The "clickable" proteome can be selectively enriched by using diverse cleavable biotin tags, but the direct identification of probe/tag-modified peptides (or peptide-centric analysis) remains challenging. Here, we evaluated the performance of five commercially available cleavable biotin tags in three most common  ...[more]
