Stereospecific assignments of valine and leucine methyl groups were obtained from a constant time 1H 13C HSQC on a 10%13C/100%15N5N [C117S]YmoB 1.4 mM sample in buffer B. One fresh sample of 15N 13C labelled [C117S]YmoB at 1.0 mM in buffer B was used for NOE correlation spectroscopy (NOESY) experiments and an equivalent fresh sample for total correlation spectroscopy (TOCSY) experiments.
