Identification of Angiotensin II-binding Domains in the Rat AT2 Receptor with Photolabile Angiotensin Analogs

To identify binding domains between angiotensin II (AngII) and its type 2 receptor (AT2), two different radiolabeled photoreactive analogs were prepared by replacing either the first or the last amino acid in the peptide with p-benzoyl-L-phenylalanine (Bpa). Digestion of photolabeled receptors with...
