photoaffinity labelling
Technique by which a photochemically reactive molecular entity, specifically associated with a biomolecule, is photo-excited in order to covalently attach a @[email protected] to the biomolecule, usually via intermediates. Identification of the resulting photo-crosslinked product provides structural information on the protein′s @[email protected]
