CD and HSQC characterization of the first Nck2 SH3 domain. (a) The NMR structure of the first human Nck2 SH3 domain (PDB code 2B86). (b and c) Far-UV CD and NMR HSQC spectra of the first SH3 domain (58 residues) of the human Nck2 protein (AAC04831) at pH 6.2 and 20°C. The protein concentration of the NMR sample was ∼200 μM.
