| Details | Sequential and intra-residue 1H, 15N, and 13C backbone and side-chain chemical shift assignments were extracted from a series of double and triple resonance NMR experiments (HNCA, HNCO, HNCACB, CBCA(CO)NH, C(CO)NH, HCC(CO)NH, 1H-13C-CT HSQC,and HCCH-TOCSY) conducted on a DRX600. nOe data were obtained from 3D 15N NOESY experiments with mixing times (tmix) of 100, 120, and 140 msec and from 3D HCHC-NOESY (tmix=140 msec) spectra acquired at 600 MHz. Additional 15N NOESY-HSQC and 13C NOESY-HSQC experiments (nOe mixing times of 120 msec) were acquired on a Varian 800 INOVA (800 MHz) instrument. |
