Structure and dynamics of a cold-active esterase reveals water entropy and active site accessibility as the likely drivers for cold-adaptation

N. Noby, H. Sabah Auhim, H. Worthy, S. Winter, A. Embady, H. Saeed, A. Hussein, C. Pudney, P. Rizkallah, S. A. Wells, D. Jones, C. R. Pudney

This study determines the structure of a cold-active esterase and identifies increased substrate accessibility and water entropy tolerance as the main drivers of its cold adaptation.

The effect of proximity on the function and energy transfer capability of fluorescent protein pairs

J. Pope, R. Johnson, W. D. Jamieson, H. Worthy, S. Kailasam, H. Auhim, D. Watkins, P. Rizkallah, O. Castell, D. Jones

This study shows that dimerization of fluorescent protein pairs alters their fluorescent properties and FRET efficiency, challenging assumptions about FP-based proximity sensing.
