Raw 16-bit tif images of -HA blots were imported into western blot detection software (Image Studio Lite, version 5.2, LI-COR, Lincoln, NE). Because each crosslinking pair is identified in an independent experiment, the proximity requirements for the formation of Cys-BrEtY adduct are not expected to be all satisfied simultaneously by a single conformational snapshot of the flexible complex. the best experience, we recommend you use a more up to date browser (or turn off compatibility mode in Solution for Identify the highlighted structures. Bttke, T. et al. After monitoring, the reaction mixture was cooled down to RT, filtered and the solvent was removed under reduced pressure. By genetically incorporating photo-activatable and electrophilic non-canonical amino acids (ncAAs) throughout the whole arr2, we define the footprint of PTH1R on the arrestin and identify 136 intermolecular pairs of proximal amino acids at the PTH1R-arr2 interface.
