Peptide phosphorylation was measured by time resolved fluorescence with 7 nM streptavidin-Surelight™ allophycocyanin (Perkin-Elmer, Waltham, MA) and 1 nM Europium-conjugated phospho-tyrosine antibodies (Perkin-Elmer). Plates were read in a Victor X5 or Viewlux 1430 ultra HTS microplate imager (Perkin-Elmer).

    • IR protein was expressed and purified as previously described (Li, S.; Covino, N. D.; Stein, E. G.; Till, J. H.; Hubbard, S. R. J. Biol. Chem. 2003, 278, 26007). Protein at 10 mg/ml was complexed with a 3-fold molar excess of inhibitor for 1 h prior to crystallization. Crystals were grown by hanging drop vapor diffusion at 22° from 0.1 M MOPS, pH 7.0, 1.0 M trisodium citrate. Crystals were flash frozen in PFO prior to data collection. The structure was solved by molecular replacement using PDB:1P14 as a starting model.
