ARIA 1.0, CNS 1.0 This structure represents the lowest energy solution based on 2406 SH2 intramolecular restraints, 1628 SH3 intramolecular restraints, 37 SH2-SH3 intermolecular restraints, 64 SH2-phosphopeptide intermolecular restraints, 50 hydrogen bonds, 54 direct 3J-HNHA couplings and 166 dihedral angle restraints from TALOS Residues 217-220 and 225-229 of the Crk phosphopeptide (Chain B) are disordered. As intermolecular contacts between the SH2 domain (Chain A) and the SH3 domain (Chain C) limited to amino acids 67-75 in DE-loop of the SH2 domain, there is no unique orientation between the SH2 domain and SH3 domain. 1
