Influenza hemagglutinin drives viral entry via two sequential intramembrane mechanisms

A. Pabis, R. J. Rawle, P. M. Kasson

The paper uses molecular dynamics simulations to show influenza hemagglutinin drives fusion via two sequential intramembrane mechanisms: lipid tail protrusion/stalk formation and distal leaflet engagement/curvature.

Bifunctional Substrate Activation via an Arginine Residue Drives Catalysis in Chalcone Isomerases

J. R. Burke, J. J. LaClair, R. N. Philippe, A. Pabis, J. M. Jez, G. A. Cortina, M. Kaltenbach, M. E. Bowman, G. V. Louie, K. B. Woods, A. T. Nelson, D. S. Tawfik, S. C. L. Kamerlin, J. P. Noel

The paper elucidates the catalytic mechanism of chalcone isomerases, showing how an arginine residue activates substrates via Bronsted and Lewis acid interactions, and highlights structural differences between type-1 and type-2 enzymes.

Evolution of chalcone isomerase from a non-catalytic ancestor

M. Kaltenbach, J. R. Burke, M. Dindo, A. Pabis, F. S. Munsberg, A. Rabin, S. C. L. Kamerlin, J. P. Noel, D. S. Tawfik

This study shows chalcone isomerase evolved from a non-catalytic ancestor through four founder mutations with weak epistasis, enabling enantioselective activity.
