Enzyme activity and flexibility at very low hydration [PDF]

, 2005
Recent measurements have demonstrated enzyme activity at hydrations as low as 3%. This raises the question of whether hydration-induced enzyme flexibility is important for activity. Here, to address this, picosecond dynamic neutron scattering experiments

The molecular basis of the effect of temperature on enzyme activity [PDF]

, 2010
Experimental data show that the effect of temperature on enzymes cannot be adequately explained in terms of a two-state model based on increases in activity and denaturation.

Ineffective degradation of immunogenic gluten epitopes by currently available digestive enzyme supplements. [PDF]

PLoS ONE, 2015
Due to the high proline content of gluten molecules, gastrointestinal proteases are unable to fully degrade them leaving large proline-rich gluten fragments intact, including an immunogenic 33-mer from α-gliadin and a 26-mer from γ-gliadin.
