Tyrosine Deprotonation Yields Abundant and Selective Backbone Cleavage in Peptide Anions upon Negative Electron transfer Dissociation and Ultraviolet Photodissociation

Tyrosine deprotonation in peptides yields preferential electron detachment upon NETD or UVPD, resulting in prominent N – Cα bond cleavage N-terminal to the tyrosine residue. UVPD of iodo-tyrosine modified peptides was used to generate localized radicals on neutral tyrosine side chains by homolytic c...
