Researchers monitored thermal unfolding of a monomeric enzyme by circular dichroism at 222 nm while heating from 20°C to 90°C in buffers of varying pH. The apparent melting temperature (TmT_m) was defined as the midpoint of the unfolding transition. Measured TmT_m values were: pH 5.0: 64°C; pH 7.0: 72°C; pH 9.0: 62°C. Based on the data, which inference about protein stability is most supported?
