Lysine sorbylation, a newly described posttranslational modification , is reported as a covalent lysine adduct formed by an electrophilic sorbyl species. The key advance is its recognition on proteins and preliminary mapping principles. This addition broade...

Lysine sorbylation, a covalent addition of sorbate to lysine side chains, is emerging as a distinct posttranslational modification uncovered by chemoproteomic mapping. Early profiles indicate selective, stimulus-responsive labeling across proteins that inte...
