FIG. 2.

An ¹H-¹⁵N HSQC spectrum of Rv2302 with the assigned cross-peaks labeled. Unassigned cross-peaks are identified with a question mark, and weak cross-peaks are identified with an “x.” The spectrum was collected at 25°C in NMR buffer (100 mM KCl, 20 mM potassium phosphate, 2.0 mM dithiothreitol, pH 7.1) at a ¹H resonance frequency of 600 MHz.
