Abstract

Using a deuterated sample, all the observable backbone (1)H(N), (15)N, (13)C(a), and (13)C' chemical shifts for the dimeric, periplasmic sensor domain of the Burkholderia pseudomallei histidine kinase RisS were assigned. Approximately one-fifth of the amide resonances are "missing" in the (1)H-(15)N HSQC spectrum and map primarily onto α-helices at the dimer interface observed in a crystal structure suggesting this region either undergoes intermediate timescale motion (μs-ms) and/or is heterogeneous.
