摘要

We have developed a highly efficient method for the site-specific attachment of biophysical probes to unprotected peptides after chemical synthesis. This methodology takes advantage of the selective reactivity of an N-methylaminooxy amino acid that is appropriately protected for direct incorporation during solid-phase peptide synthesis. The functional N- methylaminooxy group is unmasked using normal peptide cleavage conditions and is ...
