Abstract

(Chemical Equation Presented) Change the Tyr: A tyrosinase-assisted chemoenzymatic method was used to modify and enrich phosphotyrosine-containing peptides from a peptide mixture. This approach could be used to study protein tyrosine phosphorylation, and represents a promising alternative to immunoaffinity purification by using antiphosphotyrosine antibodies.
