Figure 2.
(a) Real-time NMR spectra demonstrating spontaneous, sequential interconversions among different lid domain conformations in the transition pathway between two extreme conformations: open and closed (T = 310 K, pH 7.4). Variable temperature NMR experiments demonstrating (b) temperature effect on the rate of exchange between open conformations of sol-hMGL and (c) effect of temperature on the distribution of open-closed conformers for the H272A mutant (pH 7.4).
